Abstract:
Background: Meniscal injuries are common in athletes across many sports. How professional baseball players respond to partial meniscectomy is not well documented. Purpose/Hypothesis: The purpose was to determine the performance and return-to-sports (RTS) rate in professional baseball players after arthroscopic partial knee meniscectomy and compare the results of partial medial meniscectomy versus partial lateral meniscectomy. The hypothesis was that there would be a high RTS rate in professional baseball players after partial meniscectomy with no difference in the RTS rate or timing of RTS between players who underwent partial medial meniscectomy versus partial lateral meniscectomy. Study Design: Cohort study; Level of evidence, 3. Methods: All professional baseball players who underwent arthroscopic partial meniscectomy between 2010 and 2017 were identified using the Major League Baseball Health and Injury Tracking System database. Demographic and performance data (before and after injury) for each player were recorded. The RTS rate and timing of RTS were then compared between players who underwent partial medial meniscectomy versus partial lateral meniscectomy. Results: A total of 168 knees (168 players) underwent arthroscopic partial meniscectomy (mean age, 25 ± 5 years; 46% medial meniscectomy, 45% lateral meniscectomy, and 9% both medial and lateral meniscectomy). The most common mechanism of injury was fielding in the infield on natural grass. Injuries were spread evenly across positions: 18% catchers, 24% infielders, 20% outfielders, and 38% pitchers. The overall RTS rate was 80% (76% returned to the same or a higher level, and 4% returned to a lower level). For performance, pitchers saw significant decreases in usage but significant improvements in performance using the advanced statistics of fielding independent pitching ( P < .001) and wins above replacement ( P = .011). Hitters saw significant decreases in usage but increases in efficiency as seen by improvements in wins above replacement ( P = .003). Of the 79 athletes who returned during the same season, the median time to return to play was 42 days. Conclusion: The RTS rate after meniscectomy in professional baseball players was 80%. Player efficiency improved after surgery in pitchers and position players. No difference in the RTS rate or timing of RTS existed between players who underwent partial medial meniscectomy versus partial lateral meniscectomy.

Abstract:
AimsThe aim of this study was to evaluate the cost-effectiveness of arthroscopic partial meniscectomy versus physical therapy plus optional delayed arthroscopic partial meniscectomy in young patients aged under 45 years with traumatic meniscal tears.MethodsWe conducted a multicentre, open-labelled, randomized controlled trial in patients aged 18 to 45 years, with a recent onset, traumatic, MRI-verified, isolated meniscal tear without knee osteoarthritis. Patients were randomized to arthroscopic partial meniscectomy or standardized physical therapy with an optional delayed arthroscopic partial meniscectomy after three months of follow-up. We performed a cost-utility analysis on the randomization groups to compare both treatments over a 24-month follow-up period. Cost utility was calculated as incremental costs per quality-adjusted life year (QALY) gained of arthroscopic partial meniscectomy compared to physical therapy. Calculations were performed from a healthcare system perspective and a societal perspective.ResultsA total of 100 patients were included: 49 were randomized to arthroscopic partial meniscectomy and 51 to physical therapy. In the physical therapy group, 21 patients (41%) received delayed arthroscopic partial meniscectomy during follow-up. Over 24 months, patients in the arthroscopic partial meniscectomy group had a mean 0.005 QALYs lower quality of life (95% confidence interval -0.13 to 0.14). The cost-utility ratio was €-160,000/QALY from the healthcare perspective and €-223,372/QALY from the societal perspective, indicating that arthroscopic partial meniscectomy incurs additional costs without any added health benefit.ConclusionArthroscopic partial meniscectomy is arthroscopic partial meniscectomy is unlikely to be cost-effective in treating young patients with isolated traumatic meniscal tears compared to physical therapy as a primary health intervention. Arthroscopic partial meniscectomy leads to a similar quality of life, but higher costs, compared to physical therapy plus optional delayed arthroscopic partial meniscectomy.Cite this article: Bone Joint J 2023;105-B(11):1177–1183.

Abstract:
Background: An intact meniscus is considered a secondary stabilizer of the knee after anterior cruciate ligament reconstruction (ACLR). While loss of the meniscus can increase forces on the anterior cruciate ligament graft after reconstruction, it is unclear whether this increased loading affects the success of the graft after ACLR. Purpose: To identify the risk of subsequent knee surgery when meniscectomy, either partial or total, is performed at the time of index ACLR. Study Design: Cohort study; Level of evidence, 3. Methods: We conducted a matched cohort study using data from the Kaiser Permanente Anterior Cruciate Ligament Reconstruction Registry. Patients were identified who had a primary ACLR performed between January 1, 2005 and December 31, 2016, with up to 12 years of follow-up. The study sample comprised patients with ACLR who had a lateral meniscectomy (n = 2581), medial meniscectomy (n = 1802), or lateral and medial meniscectomies (n = 666). For each meniscectomy subgroup, patients with ACLR alone were matched to patients with a meniscectomy on a number of patient and procedure characteristics. After the application of matching, Cox proportional hazards regression was used to evaluate the risk of aseptic revision, while competing risks regression was used to evaluate the risk of cause-specific ipsilateral reoperation between meniscectomy and ACLR alone. Analysis was performed for each meniscectomy subgroup. Results: After the application of matching, we failed to observe a difference in aseptic revision risk for patients with ACLR and a meniscectomy—lateral (hazard ratio [HR], 0.80; 95% CI, 0.63-1.02), medial (HR, 0.95; 95% CI, 0.70-1.29), or both (HR, 1.25; 95% CI, 0.77-2.04)—as compared with ACLR alone. When compared with patients who had ACLR alone, patients with a lateral meniscectomy had a higher risk for subsequent lateral meniscectomy (HR, 1.89; 95% CI, 1.18-3.02; P = .008), and those with a medial meniscectomy had a lower risk for manipulation under anesthesia (HR, 0.13; 95% CI, 0.02-0.92; P = .041). Conclusion: No difference in aseptic revision risk was observed for patients undergoing primary ACLR between groups with and without meniscectomy at the time of index surgery. Partial lateral meniscectomy at the time of index ACLR did associate with a higher risk of subsequent lateral meniscectomy.

Abstract:
SummaryTotal removal of a knee joint meniscus is followed by osteoarthritis in many mammalian species. Altered load-bearing has been observed in the human knee following meniscectomy but less is known about biochemical effects of meniscectomy in other species. Using pressure sensitive paper in sheep knee (stifle) joints it was found that, for comparable loads, the load-bearing area on the medial tibial condyle was significantly reduced following medial meniscectomy. Also, for loads of between 50 N and 500 N applied to the whole joint, the slope of the regression of contact area against load was much smaller. Following medial meniscectomy, the ability to increase contact area as load increased was markedly reduced.The load bearing area on the medial tibial condyle was reduced following meniscectomy.

Abstract:
Background: There are limited data comparing the outcomes of similarly matched patients with a medial meniscus posterior root tear (MMPRT) treated with nonoperative management, partial meniscectomy, or repair. Purpose/Hypothesis: The purpose was to compare treatment failure, clinical outcome scores, and radiographic findings for a matched cohort of patients who underwent either nonoperative management, partial meniscectomy, or transtibial pull-through repair for an MMPRT. We hypothesized that patients who underwent meniscus root repair will have lower rates of progression to arthroplasty than patients who were treated with nonoperative management or partial meniscectomy. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent transtibial medial meniscus posterior horn root repair were matched by meniscal laterality, age, sex, and Kellgren-Lawrence (K-L) grades to patients treated nonoperatively or with a partial meniscectomy. Progression to arthroplasty rates, International Knee Documentation Committee and Tegner scores, and radiographic outcomes were analyzed between groups. Results: Forty-five patients were included in this study (15 nonoperative, 15 partial meniscectomy, 15 root repair). Progression to arthroplasty demonstrated significant differences among treatment groups at a mean of 74 months (nonoperative, 4/15; partial meniscectomy, 9/15; meniscal repair, 0/15; P = .0003). The meniscus root repair group had significantly less arthritic progression, as measured by change in K-L grade from pre- to postoperatively (nonoperative, 1.0; partial meniscectomy, 1.1; meniscal repair, 0.1; P = .001). Conclusion: Meniscus root repair leads to significantly less arthritis progression and subsequent knee arthroplasty compared with nonoperative management and partial meniscectomy in a matched cohort based on patient characteristics.

Abstract:
Background: Meniscal tears are common in active patients, but treatment trends and surgical outcomes in young patients with lateral meniscal tears are lacking. Purpose: To evaluate treatment trends, outcomes, and failure rates in young patients with lateral meniscal tears. Study Design: Cohort study; Level of evidence, 3. Methods: Patients aged ≤25 years treated surgically for isolated lateral meniscal tears from 2001 to 2017 were identified. Treatment trends were compared over time. International Knee Documentation Committee (IKDC) scores and failure rates were compared by treatment modality (meniscectomy vs meniscal repair). Failure was defined as reoperation, symptomatic osteoarthritis, or a severely abnormal IKDC score. Univariate regression analyses were performed to predict failure and IKDC scores based on treatment, type and location of tear, or extent of meniscectomy. Results: Included were 217 patients (226 knees) with a mean age of 17.4 years (range, 7-25 years); of these patients, 144 knees (64%) were treated with meniscectomy and 82 knees (36%) with meniscal repair. Treatment with repair increased over time compared with meniscectomy ( P < .001). At a minimum 2-year follow-up (mean, 6.1 ± 3.9 years), 107 patients (110 knees) had IKDC scores, and analysis indicated that although scores in both groups improved from pre- to postoperatively (repair: from 69.5 ± 13.3 to 97.4 ± 4.3; meniscectomy: from 75.7 ± 9.0 to 97.3 ± 3.9; P < .001 for both), improvement in IKDC score was greater after repair (27.9 ± 13.9) versus meniscectomy (21.6 ± 9.4) ( P = .005). Included in the failure analysis were 184 patients (192 knees) at a mean follow-up of 8.4 ± 4.4 years. The rates of reoperation, symptomatic osteoarthritis, and failure were not significantly different between the meniscectomy and repair groups. Conclusion: An increase was seen in the rate of isolated lateral meniscal tear repair in young patients. IKDC score improvement was greater after repair than meniscectomy, although postoperative IKDC scores were similar. Symptomatic arthritis, reoperation, and failure rates were similar between groups; however, there was a trend for increased arthritis symptoms in patients treated with meniscectomy, especially total meniscectomy. Treatment modality, type and location of tear, and amount of meniscus removed were not predictive of final IKDC scores or failure.

Abstract:
Meniscal tears are the commonest knee injury and currently are addressed almost exclusively by arthroscopy. Ian Smillie the late Professor of orthopaedics in Tayside, popularised open total meniscectomy worldwide during the 1950s believing that this was necessary for a functioning fibrocartilage replica to completely occupy the ensuing space. The cohort in this study underwent open total meniscectomy under his care prior to their 19th birthday. It was documented in their then records that no other knee pathology was observed during the operation and that the same post operative regime was followed by all. This presents a unique opportunity to evaluate the long term outcomes of open total knee meniscectomy during adolescence and to further investigate biological markers of osteoarthritis 40 years down the line. Fifty-three patients who underwent radiographic evaluation at the 30 year follow-up were further studied at this 40 year review. All surviving and contactable patients were consented prior to assessment and were evaluated clinically; biochemically, radiologically and subjectively once ethical approval and funding were secured. Standardisation of all methods used for examination, radiographic evaluation, sampling of serum and synovial fluid and patient reported outcome measures (PROMs) was achieved by the use of recognised, validated and credible systems as well as good communication between all involved parties. Such examples include the construction of a wooden apparatus standardising the weight bearing skyline views and the need for a smooth and efficient transition between sampling, preparing, storing and transferring the synovial and serum samples. Once all the data were collected, the first striking finding was the proportion of total knee arthroplasties (TKAs) observed as a hard endpoint in this cohort, which suggested a 132 fold increase when compared to their age and geographically matched population data, as per Scottish Arthroplasty Project. It was important to assess if in this cohort the site of meniscectomy demonstrated a significant difference in terms of tibiofemoral joint (TFJ) osteoarthritis, range of motion (ROM) and PROMs as per our chosen scoring systems. As this proved not to be the case, the operated knee was assessed against the non-operated knee where possible and not as per site of meniscectomy. Also the assessed sagittal laxity between the knees did not demonstrate any significant difference and as such was excluded as a confounding factor in terms of initiators of osteoarthritis. A linear correlation was observed between the chosen scoring systems of TFJ osteoarthritis. The calculated relative risk (RR) of developing osteoarthritis (OA) in the operated vs. non-operated knee was calculated for both the KL & Ahlback grading systems with presumed osteoarthritis as =2 for KL & =1 for Ahlback. This was found to be 4.5 & 4.25 respectively. Decreased ROM between the Index and Non-index knees was observed, with the ROM correlating with PROMs and inversely with TFJ OA. In addition the usually under investigated patellofemoral joint was assessed. Patellofemoral joint osteoarthritis was noted in the index knees as opposed to the non-index knees with an observed RR of 1.8 as per presence of osteophytes. There was no significant difference in the degree of patellofemoral joint (PFJ) osteoarthritis between lateral and medial meniscectomies. There was however significant correlations between the joint space narrowing (JSN) and PROMs, TFJ OA and ROM. Worsening results were observed where the PFJ was <5mm. Malalignment was greater in those knees that underwent medial meniscectomy as opposed to either lateral or medial & lateral meniscectomies. Malalignment demonstrated correlation with ROM and TFJ OA. Serum and synovial fluid was processed and analysed with regards to biomarkers of OA in the form of MMP-3 and GAG. Neither serum nor synovial MMP-3 demonstrated any significant correlation with other measured parameters. GAG on the other hand demonstrated a significant difference between the index and non-index knee as well as a positive correlation to IKDC and an inverse correlation with TFJ OA. Although this is suggesting that synovial GAG as a biomarker for OA may indicate progression of disease and symptoms, the wider spread of values questions this. Two different PROMs were utilised to assess this cohort. Interestingly the KOOS demonstrated that in all its 5 parameters the cohort was symptomatic. Correlations were observed between the KOOS ADL & Sport as well as IKDC with TFJ OA. This is currently the longest follow-up of open total meniscectomy in adolescence worldwide. A >4 fold increased risk of osteoarthritis in the operated knee as compared to the non-operated knee was demonstrated and possibly a 132 fold increase in TKA as compared to their aged matched geographical peers.

Abstract:
This study investigated the effects of hyperbaric oxygen (HBO2) therapy following partial arthroscopic meniscectomy surgery on swelling, perceived pain, range of motion at the knee joint, isokinetic strength, and leg function. Subjects were 8 males and 1 female with an acute tear to the meniscus. Subjects were randomly assigned to either a control group (n = 5) or an HBO2 treatment group (n = 5). The HBO 2 group received 5 HBO2 treatments at 2.5 ATA for 90 minutes at 95% O2 beginning 24 hours post-operation. Both groups were tested pre-operation (day 0) and on days 1, 2, 3, 4, 5, 20, 35, and 50 post-surgery. No significant difference was found between groups for any of the dependant variables. The results indicated that the control and HBO2 groups responded in a similar pattern when assessed for swelling, perceived pain, range of motion at the knee joint, leg function and isokinetic strength.

Abstract:
Relatório do Projeto de Investigação apresentado para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Fisioterapia, área de especialização em Fisioterapia em Condições Músculo-Esqueléticas<br>Enquadramento: A ruptura meniscal do joelho, apresenta uma taxa de ocorrência estimada por ano de 23.8/100000 (Clayton, & Court-Brown’s, 2008). Os tratamentos artroscópicos, a rupturas meniscais, estão entre os mais comuns realizados pelos cirurgiões ortopédicos, constituindo 10% a 20% de todas as cirurgias em alguns centros cirúrgicos (Renstrom & Johnson, 1990 cit. por Shybut & Strauss, 2011). Os objectivos da Fisioterapia, pós-operatória da artroscopia meniscal, são assim resolver os sintomas, restaurar a função, prevenir lesões futuras e promover o retorno à atividade. (Goodyear-Smith & ·Arroll, 2001). Objetivo: Este estudo teve por objetivo investigar prospetivamente a evolução da intensidade da dor, rigidez articular e função física, em utentes que se encontravam a realizar fisioterapia pós-meniscectomia. Adicionalmente, pretendeu-se conhecer o beneficio percepcionado pelos participantes, relativamente à evolução da sua condição. Tipo de Estudo: Trata-se de um estudo do tipo observacional de Coorte prospectivo no qual se registou a evolução da dor, rigidez e funcionalidade ao longo de 8 semanas, em indivíduos submetidos a cirurgia de meniscectomia e que se encontram a realizar tratamento de Fisioterapia. No final da 4ª e 8ª semanas de intervenção foi ainda avaliada a percepção de mudança do estado de saúde e satisfação com o tratamento. Instrumentos: Questionário de caracterização sócio-demográfica e clínica, END, WOMAC, PGIC-PT. Amostra: Dos 33 pacientes iniciais, 8 foram excluídos, constituindo os restantes 25 a amostra em estudo. Resultados: Ocorreu uma diminuição da dor de 52% de 5 (T0) para 2.4 (T3) segundo a END, a sub-escala dor da WOMAC reportou uma diminuição da dor de 45% de 7.92 (T0) para 4.36 (T3). A sub-escala rigidez da WOMAC apresentou uma diminuição de 65,2% de 4.2 (T0) para 1.5 (T3). Verificou-se um aumento da funcionalidade, através da sub-escala da funcionalidade da WOMAC 36,12 (T0) para 16.92 (T3) representando um aumento funcional de 53.26%. Relativamente à WOMAC total observouse uma redução na pontuação de 48.32 (T0) para 22.88 (T3), o que se traduziu numa melhoria de 52.81% da função final. Os resultados mostram ainda que após a intervenção de Fisioterapia ocorreu uma redução significativa da, intensidade dor X2 (3)= 46.130, p<0.0005, e da incapacidade funcional X2 (3)= 53.069, p<0.0005. As melhorias foram percepcionadas como clinicamente importantes (PGICPT ≥5) para 72% dos participantes no estudo. Foi também possível observar parcialmente uma associação positiva e significativa entre a intensidade da dor e o nível de incapacidade funcional autoreportado. Verificou-se ainda que existe uma associação positiva e significativa entre a redução da incapacidade funcional e a melhoria percepcionada pelos indivíduos pós-meniscectomia, durante e após o tratamento de Fisioterapia. Conclusão: Com base nos resultados observados, este estudo parece indicar uma melhoria clínica dos pacientes a realizar Fisioterapia pós-meniscectomia, quer a nível dos resultados clínicos, quer na melhoria percepcionada pelo paciente.<br>Background: The knee meniscal rupture has a rate estimated to occur each year 23.8/100000 (Clayton & Court-Brown’s, 2008). Arthroscopic treatments of meniscal injuries are among the most common orthopaedic procedures performed, constituting 10% to 20% of all surgeries at some centers (Renstrom & Johnson, 1990 cit. por Shybut & Strauss, 2011). The rehabilitation objectives in meniscal postoperatory arthroscopy are resolving the symptoms, restore function, prevent further injuries and promote return to activity. Post-operatory rehabilitation generally follows a phased progressive approach (Goodyear-Smith &·Arroll, 2001). Objective: This study aimed to prospectively investigate the evolution of the intensity of pain, stiffness and physical function in users who were conducting physiotherapy after meniscectomy. Additionally, we sought to understand the benefit perceived by participants regarding the progress of his condition. Study Type: This is a study of a prospective observational cohort study, in which was recorded the evolution of pain, stiffness and function over 8 weeks in patients undergoing meniscectomy surgery and are conducting physiotherapy treatment. At the end of the 4th and 8th weeks of intervention was also assessed, perceptions of change in health status and satisfaction with treatment. Instruments: Questionnaire of socio-demographic and clinical characterization, Numerical Rating Pain Scale, Western Ontario and McMaster Universities Osteoarthritis Index, Patients Global Impression of Change Scale. Participants: Of the initial 33 patients, 8 participated to the 4th week the remaining 25 patients completed the study, which (n=25) were subject to statistical analysis. Results: Results show pain diminishment of 52% from a initial 5 (T0) to 2.4 (T3) occurred according to NRPS, the pain subscale of WOMAC reported a pain reduction of 45% from 7.92 (T0) to 4:36 (T3). A stiffness subscale of the WOMAC fell by 65.2% from 4.2 (T0) to 1.5 (T3). There was an increased functionality through the sub-range of functionality of WOMAC 36.12 (T0) to 16.92 (T3) representing a functional increase of 53.26 %. For the total WOMAC is observed 48.32 (T0) to 22.88 (T3), which resulted in an improvement of 52.81 % of the final function. The study also found that after the intervention of physical therapy a significant reduction in pain intensity X2 (3) = 46,130, p < 0.0005, a significant reduction in disability X2 (3) = 53,069, p < 0.0005 occurs. Users who reported a clinically important change (≥5) in PGIC - PT, the improvements were perceived as clinically important in 72 % of study participants. Is partially corroborated a positive and significant association between pain intensity and the level of self-reported functional disability. It was also found that there is a positive and significant association between reduction in functional disability and perceived improvement by post-meniscectomy individuals, during and after treatment of Physiotherapy. Conclusion: Based on the observed results, this study demonstrates clear implications not only in the clinical improvement of patients undergoing physiotherapy after meniscectomy, and lets say that the patient perceives it as very useful for the resumption of normal life.

Abstract:
Pre-operatively (pre-op) and following arthroscopic partial meniscectomy (every 2 weeks for 12 weeks), bilateral knee extensor and flexor peak torques (PT) were evaluated at the Sports Medicine Lab (SML) and Sacre Coeur Hospital (SCH) via Cybex II or II+, in 22 subjects. Three submaximal contractions were followed by 3 maximal contractions at 60, 120, 180 and 240 deg/sec, with a 2 minute rest between sets. For both groups, the quadriceps had a significant deficit in PT at pre-op, except at 180 and 240 deg/sec at the SML, whereas the hamstrings only had a significant deficit at 60 deg/sec. Despite significant differences in PT (SML $>$ SCH) and percent deficit (SCH $>$ SML) the recovery pattern was similar in both groups. Extensor PT dropped significantly at 2 and 4 weeks post-op, returned to pre-op values by 6 weeks post-op and plateaued at this level until and including 12 weeks post-op. Flexor PT dropped significantly at 2 weeks post-op, except at the faster speeds, and was fully recovered 2 weeks later. These results indicate that while the hamstrings were minimally involved, the extensors were not able to recover beyond their pre-op level of strength within 3 months, without training. The differences between the SML and SCH may be attributed to differences in Cybex machines, thigh muscle cross sectional area and tourniquet time.

Abstract:
Thigh muscle strength and endurance were measured following partial arthroscopic meniscectomy of the knee in 24 patients divided into group 1 (age < 20 yr), group 2 (age 24-40 yr), and group 3 (age > 50 yr). Subjects were studied during and after release from isokinetic rehabilitation. Isokinetic testing was performed at 1.04, 2.09, 3.14, 4.19, and 5.24 radians/second, with release from rehabilitation when quadriceps strength achieved 85% recovery of the non-surgical leg.No significant difference existed among the 3 groups in days from the time of surgery to the start of the first test or for the weeks to release from rehabilitation. Approximately 50% quadricep muscle strength loss was observed at the time of the initial isokinetic test. Quadriceps torque (mean + SE) measured in newton-meters for group 1 at the 1.04 rad/sec speed showed the surgical leg significantly weaker (P<0.001) than the non-surgical leg when tested at the initial test (101.6 +18.2 vs. 189.6 +17.2) and at release from rehabilitation (157.4 +13.3 vs. 176.3 +15.2). Torque measured at the other 4 speeds reached non-significance by the second or third week of rehabilitation. Isokinetic testing for groups 2 and 3 showed surgical leg strength significantly weaker (P<0.05) at the initial test and at week 1 of rehabilitation for the 5 testing speeds, with 85% return of strength by weeks 2 or 3. Strength recovery for all 3 groups showed no significant weakness between legs for hamstring torque after the initial or after the first week of rehabilitation. Percent of knee extensor torque achieved by the knee flexor muscles of the surgical leg for the 3 groups showed significantly greater (P<0.001) values only for the initial test at speeds 1.04 and 2.09 rad/sec. Measures of total work, average power, and endurance calculated from work tests showed little change in muscle endurance between legs.These data indicate that quadricep muscle function is negatively affected following arthroscopic meniscectomy. Release from rehabilitation when surgical to non-surgical leg strength is between 85% to 90X appears to be a valid measure for most patients, which indicates age alone does not appear to be a limiting factor in regaining strength.

Abstract:
A rabbit lateral meniscectomy model was used to induce osteoarthritis. Separate studies were conducted to evaluate the progression of osteoarthritis and to identify possible biological markers. First, 21 male, New Zealand White rabbits were divided into 3 groups (n = 7 / group). A randomly selected left or right stifle underwent a lateral meniscectomy. The 3 groups were: corticosteroid administration, forced exercise and surgical control. An open field maze was used to assess mobility weekly. The rabbits were euthanitized 47 days after surgery. Histopathologic examination found that the lateral meniscectomy induced more severe lesions than in the non-surgical contralateral stifle. It also showed a significant sparing effect on erosion of cartilage in the corticosteroid group. The corticosteroid group, but not the exercise group, caused a significant increase in mobility (p = 0.008) compared to the surgical control. Secondly, synovial fluid was harvested from the 12 rabbits on days 0, 6, 26, 40, and 57 with surgery occurring on day 12. Trypan blue was used in the lavage fluid to estimate the volume of harvested synovial fluid. There was a significant increase in the volume harvested on day 26 (p < 0.001). Superoxide dismutase concentration in synovial fluid increased after surgery, although not significantly. These studies verify that the lateral meniscectomy model produce histopathologic lesions consistent with osteoarthritis. Furthermore, use of trypan blue appears to be a reliable concentration marker in a lavage sample to measure harvested synovial fluid.<br>Master of Science

Full text
Abstract:
Calcium pyrophosphate crystal deposition (CPPD) is rare in younger adults but becomes increasingly common over the age of 55 years, especially at the knee. Ageing and osteoarthritis (OA) are the main attributable risk factors. Hyperparathyroidism, hypomagnesaemia, haemochromatosis, and hypophosphatasia are other less common risk factors. Rare families with familial CPPD have been reported from many different parts of the world, and mainly present as young-onset polyarticular CPPD. Recent studies suggest that CPPD occurs as the result of a generalized constitutional predisposition and may also associate with low cortical bone mineral density. Previous meniscectomy, joint injury, and constitutional knee malalignment are local biomechanical risk factors specifically for knee chondrocalcinosis. Although associated with OA, current evidence suggests that CPPD does not associate with development or progression of OA.

Abstract:
Meniscectomy is a well-known risk factor for osteoarthritis (OA) in humans. It has been reported that total meniscectomy increases the risk of developing osteoarthritis radiographically by 14 times after 21 years [1] and that partial meniscectomy increases the risk of developing radiographic evidence of osteoarthritis within 16 years by a factor of four [2]. Two possible functional measures have been suggested as mechanisms for the development and progression of premature knee osteoarthritis: alterations in either kinematics or kinetics. Changes in kinematics, such as a shift in internal-external (IE) rotation after anterior cruciate ligament injury, have been suggested as a basis for an increased rate of cartilage thinning [3]. The other possible reason for the development of premature OA post-meniscectomy is a change in kinetics, the mechanical loading that occurs, particularly in the medial compartment [4]. The knee adduction moment has been associated with the rate of progression of osteoarthritis [5] and it has thus been suggested that the knee adduction moment is a good surrogate measure for in vivo load on the medial compartment osteoarthritis [6].

Full text
Abstract:
Meniscal injury is a well-known risk factor for osteoarthritis (OA); the leading treatment (meniscectomy) increases the risk for osteoarthritis four times over sixteen years [1]. Reports that meniscectomy patients display altered gait kinetics and kinematics post-operation [2,3] suggest altered gait mechanics as a potential link between meniscal resection and increased risk for OA. Specifically it has been suggested that altered gait is a pathway to OA by causing a shift in tibiofemoral cartilage contact location to unprepared regions, which leads to cartilage breakdown [4]. The altered gait mechanics of particular interest are secondary motions of the knee, including internal-external (IE) rotation and adduction angle. While previous research has shown there to be a decrease in early stance (ES) and mid-stance (MS) range of motion (ROM) in knee flexion angle along with decreased peak extension of the affected versus contralateral limb, there is a lack of data relating the interaction between primary (flexion) and secondary (IE rotation and adduction angle) motions of the knee in the meniscectomy population [2,3]. Yet this information is important for understanding the ambulatory conditions associated with knee OA following meniscectomy.

Abstract:
Abstract Partial or complete removal of the meniscus has been found to produce progressive degeneration in the knee characteristic of osteoarthritis (OA) (4). Experimental models of meniscectomy have been successful in reproducing many changes in articular cartilage with OA, including fibrillation, compositional and metabolic changes (2,5,9,11). In both human OA and experimental models of joint instability, loss of tensile stiffness of the articular cartilage has been reported as an early sign of degeneration (1,6,8,10). Little is currently known of the mechanical properties of cartilage following meniscectomy and their relationship to progressive degeneration (7). The objective of this study was to quantify the tensile properties of articular cartilage in an experimental model of meniscectomy and to compare these findings with those of both human OA and experimental models of joint instability.

Abstract:
Irreparable tears of the posterior horn of the medial meniscus are the most common meniscal injury and arthroscopic partial meniscectomy is the current standard of care (1–3). However, despite the excellent results of partial meniscectomy, there is still little known regarding the effects of the size of a resection on tibiofemoral stability, as measured by laxity and anterior-posterior (AP) position. Therefore in this study, we sought to determine this by conducting three successive partial meniscectomies of the posterior horn of the medial meniscus (PMM) and measuring the laxity and AP position of the medial femoral condyle over a series of loading conditions following each resection. It was hypothesized that more than a 50% resection would result in significant changes in laxity and AP position equivalent to a 100% removal of the PMM.

Abstract:
Analysis of the stress distribution within cartilages of the human knee joint in response to external loads can help to understand the causes of pathological cartilage degeneration and lead to prevention of injury. Wilson et al [1] demonstrated that by modeling the cartilage material as isotropic, type-2 damage can be explained and with the assumption of transverse isotropic properties, type-1 damage could be explained. In this study, we explore the effect of meniscectomy on the shear stress distribution through the knee joint cartilages by modeling the cartilage as three layers and considering the biphasic properties of the top, middle and deep zones. The results of the analysis indicate that complete meniscectomy of the knee joint induces the maximum shear stress at the cartilages surface to increase substantially. This suggests the need for developing an artificial meniscus that could replace the damaged one.

Abstract:
Meniscal injury has been found to leave patients at high risk for the development of knee osteoarthritis (OA). Partial meniscectomy is often used to treat meniscal tears, and while this procedure adequately addresses pain and the restoration of function, it does not prevent the progression of OA in the injured knee. Often during arthroscopy, surgeons identify areas of “softened” cartilage, which do not always correlate with visible signs of surface damage or cartilage loss. This softening has been related to changes in the cartilage matrix, which could represent early structural damage that can lead to irreversible cartilage damage and OA.
