Abstract:

Background and objectives: Previous studies consistently found no significant difference between supervised and home-based rehabilitation after anterior cruciate ligament reconstruction (ACLR). However, the function of the nonoperative knee, hamstring strength at deep flexion, and neuromuscular control have been overlooked. This prospective observational study was performed to investigate the outcomes after ACLR in operative and nonoperative knees between supervised and home-based rehabilitations. Materials and Methods: After surgery, instructional videos demonstrating the rehabilitation process and exercises were provided for the home-based rehabilitation group. The supervised rehabilitation group visited our sports medicine center and physical therapists followed up all patients during the entire duration of the study. Isokinetic muscle strength and neuromuscular control (acceleration time (AT) and overall stability index (OSI)) of both operative and nonoperative knees, as well as patient-reported knee function (Lysholm score), were measured and compared between the two groups 6 months and 1 year postoperatively. Results: The supervised rehabilitation group showed higher muscle strength of hamstring and quadriceps in nonoperative knees at 6 months (hamstring, p = 0.033; quadriceps, p = 0.045) and higher hamstring strength in operative and nonoperative knees at 1 year (operative knees, p = 0.035; nonoperative knees, p = 0.010) than the home-based rehabilitation group. At 6 months and 1 year, OSIs in operative and nonoperative knees were significantly better in the supervised rehabilitation group than in the home-based rehabilitation group (operative knees, p < 0.001, p < 0.001; nonoperative knees, p < 0.001, p < 0.001, at 6 months and 1 year, respectively). At 1 year, the supervised rehabilitation group also demonstrated faster AT of the hamstrings (operative knees, p = 0.016; nonoperative knees, p = 0.036). Lysholm scores gradually improved in both groups over 1 year; however, the supervised rehabilitation group showed higher scores at 1 year (87.3 ± 5.8 vs. 75.6 ± 15.1, p = 0.016). Conclusions: This study demonstrated that supervised rehabilitation may offer additional benefits in improving muscle strength, neuromuscular control, and patient-reported knee function compared with home-based rehabilitation up to 1 year after ACLR.

Abstract:

Therapeutic Yoga can be especially well-suited to aiding in the rehabilitation of knee injuries. This article discusses some common types of knee injuries and how Yoga can help rehabilitate some knee injuries. Specific âsanas for the knees are discussed, as well as how to work with the wellness of the whole person through âsana, prânâyâma, and meditation. Consideration is given to how Yoga therapists can work with other healthcare providers to improve the safety and efficacy of Yoga therapy. Two case studies of knee rehabilitation through Yoga therapy (one in a group class setting, and one in private Yoga therapy) are described, including details of the Yoga interventions that helped both individuals avoid surgical intervention.

Abstract:

Background: Understanding objective measures of ACL-reconstructed knee function is important in determining the efficacy of rehabilitation protocols and a patient’s return to activities of daily living and sport activities. Objective: To assess the range of motion (ROM), isokinetic strength (torque) and functional performance measures (hop test) of ACL-reconstructed and ACL-intact knees. Methods: Twelve volunteers (5 females, 7 males) with unilateral ACL injury and reconstruction were given a battery of tests (hop test for distance, knee range of motion, knee extensor isokinetic testing to assess both affected and unaffected lower limb function, flexibility and strength. Main effects and interactions were analyzed by mixed-model repeated measures ANCOVA. Dependent variables included hop test for distance, knee flexion and extension range of motion, and knee extensor isokinetic torque. The independent variables were the intact/reconstructed ACL knee and time from surgery. Sex was the covariate. Results: No statistically significant differences (p>0.05) were found across all dependent variables hop test for distance (P = 0.939), knee flexion (P = 0.576) and extension (P = 0.431) ROM, and knee extensor torque (eccentric P = 0.923 and concentric P = 0.723) for the main effects and interactions of knee (ACL-reconstructed and ACL-intact) and time (0-12 months, 13-24 months, 25-36 months and 37+ months). The covariate, sex, did produce significant differences for the hop test (P < 0.0001) and isokinetic testing (eccentric peak torque P = 0.003 and concentric peak torque P=0.012). Conclusions: Clinicians may consider present rehabilitation protocols to be adequate in developing ROM and isokinetic strength following ACL reconstruction. However, greater improvements in ROM and strength may be achieved over an extended period following ACL reconstruction surgery.

Abstract:

A safe rehabilitation exercise for anterior cruciate ligament (ACL) injuries needs to be compatible with the normal knee arthrokinematics to avoid abnormal loading on the joint structures. The objective of this study was to measure the amount of the anterior tibial translation (ATT) of the ACL-deficient knees during selective open and closed kinetic chain exercises. The intact and injured knees of fourteen male subjects with unilateral ACL injury were imaged using uniplanar fluoroscopy, while the subjects performed forward lunge and unloaded/loaded open kinetic knee extension exercises. The ATTs were measured from fluoroscopic images, as the distance between the tibial and femoral reference points, at seven knee flexion angles, from 0° to 90°. No significant differences were found between the ATTs of the ACL-deficient and intact knees at all flexion angles during forward lunge and unloaded open kinetic knee extension (). During loaded open kinetic knee extension, however, the ATTs of the ACL deficient knees were significantly larger than those of the intact knees at 0° (). It was suggested that the forward lunge, as a weight-bearing closed kinetic chain exercise, provides a safer approach for developing muscle strength and functional stability in rehabilitation program of ACL-deficient knees, in comparison with open kinetic knee extension exercise.

Abstract:

If not treated adequately, the knee injuries in adolescents can cause long-term functional impairments. The aim of our study was to quantify the functioning capacity in children who suffered soft tissues and/or bone lesions of the knee treated by arthroscopy. We reviewed the medical charts of 5 adolescent patients diagnosed with sport knees injuries, admitted in our clinic in the last two years. Arthroscopy was made three weeks after the injury. Afterwards, they were addressed to the Rehabilitation Department and followed the physical exercise programme. The patients were assessed at the beginning of rehabilitation and after 3 months: knee ROM (flexion and extension deficit) and International Knee Documentation Committee (IKDC) subjective evaluation. At the final assessment all patients presented significantly improvements in knee range of motion and functional capacity. Arthroscopic surgery, followed by a tailored rehabilitation programme, is important in the management of adolescents with knee injuries.

Abstract:

The knee is one of the largest and most complex joints in the body. The knee joins the thigh bone (femur) to the shin bone (tibia). The smaller bone that run alongside the tibia and the knee cap are the other bones that makes the knee joint. Osteoarthritis is the most common form of arthritis and often affects the knee, due to ageing. It can be common in children also. Prompt physical therapy leads to achieve functional goals. Bow leg deformity also called as genu varum. In this the legs are curved outwards at the knees. It is rarely serious and usually goes away with treatment. A 58-year-oldlady presented with genu varum which was diagnosed since last six years. The patient complains of chronic pain and was unable to walk and sit on the floor. The patient started physiotherapy treatment which comprise of exercises, electrotherapy, gait training for a period of six weeks which resulted in improvements in pain, range of motion, functional activities. The present case report suggests that classic and prompt structure physical rehabilitation led to improving the functional goals progressively and significantly which majorly leads to a successful recovery

Abstract:

After knee anterior cruciate ligament reconstructive surgery, the recovery of the former level of physical activity takes from 3 to 12 months. Such a wide range of recovery period of physical activity suggests that rehabilitation in most cases is not optimal. According to the majority of authors, after the surgery, a patient can resume intensive physical activity, when the difference in muscle strength between the operated lower extremity and another extremity is not greater than 10–15%. The aim of this study was to compare the impact of intensive and normal rehabilitations on the recovery of knee extensor muscle strength after the surgery. Material and methods. A total of 40 patients were enrolled in this study. The subjects were divided into two groups. Both groups were engaged in physical activity. The mean age of patients (16 men and 4 women) in the first group at the time of surgery was 26.4±8.1 years, mean height – 179.8±8.5 cm, and mean weight – 76.0±14.0 kg. An intensive rehabilitation was applied for the first group of the patients studied. The second group consisted of 13 men and 7 women who were engaged in moderate physical activity. Their mean age at the time of surgery was 27.0±9.3 years, mean height – 173.2±6.2 cm, and mean weight – 71.0±9.0 kg. A traditional rehabilitation was applied to this group. Muscle strength was measured in the patients of both groups studied approximately 5.2 months following surgery using the Biodex isokinetic dynamometer. Results. The patients undergoing an intensive rehabilitation achieved higher levels of knee extensor muscle strength than those patients undergoing a traditional rehabilitation program. Applying an aggressive rehabilitation program, knee extensor muscles recover more quickly than using a traditional rehabilitation program. The comparison of intensive and traditional rehabilitation programs applied to the operated and unoperated lower extremities has shown that the indexes of knee extensor muscle strength differed by 11.51– 12.74%. Applying a traditional rehabilitation, a 23.68–49.42% difference in knee flexor muscle strength between operated and unoperated extremities was noted. Conclusions. The effect of intensive rehabilitation aimed at strength recovery of knee extensor muscles after anterior cruciate ligament reconstructive surgery is greater than after ordinary rehabilitation.

Abstract:

Background:Polycentric knees for transfemoral prostheses have a variety of geometries, but a survey of literature shows that there are few ways of comparing their performance.Objectives:Our objective was to present a method for performance comparison of polycentric knee geometries and design a new geometry.Study design:In this work, we define parameters to compare various commercially available prosthetic knees in terms of their stability, toe clearance, maximum flexion, and so on and optimize the parameters to obtain a new knee design.Methods:We use the defined parameters and optimization to design a new knee geometry that provides the greater stability and toe clearance necessary to navigate uneven terrain which is typically encountered in developing countries.Results:Several commercial knees were compared based on the defined parameters to determine their suitability for uneven terrain. A new knee was designed based on optimization of these parameters. Preliminary user testing indicates that the new knee is very stable and easy to use.Conclusion:The methodology can be used for better knee selection and design of more customized knee geometries.Clinical relevanceThe method provides a tool to aid in the selection and design of polycentric knees for transfemoral prostheses.

Abstract:

Background: The relationship between the biomechanical dose of rehabilitation exercises administered after anterior cruciate ligament (ACL) reconstruction and the healing response of the graft and knee is not well understood. Hypothesis: After ACL reconstruction, rehabilitation administered with either accelerated or nonaccelerated programs produces the same change in the knees’ 6 degrees of freedom, or envelope, laxity values. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Patients who underwent ACL reconstruction with a bone–patellar tendon–bone autograft were randomized to rehabilitation with either accelerated (19 week) or nonaccelerated (32 week) programs. At the time of surgery, and then 3, 6, 12, and 24 months later, the 6 degrees of freedom knee laxity values were measured using roentgen stereophotogrammetric analysis and clinical, functional, and patient-oriented outcome measures. Results: Eighty-five percent of those enrolled were followed through 2 years. Laxity of the reconstructed knee was restored to within the limits of the contralateral, normal side at the time of surgery (baseline) in all participants. Patients in both programs underwent a similar increase in the envelope of knee laxity over the 2-year follow-up interval (anterior-posterior translation 3.2 vs 4.5 mm, and coupled internal-external rotations 2.6° vs 1.9° for participants in the accelerated and nonaccelerated programs, respectively). Those who underwent accelerated rehabilitation experienced a significant improvement in thigh muscle strength at the 3-month follow-up ( P < .05) compared with those who participated in nonaccelerated rehabilitation, but no differences between the programs were seen after this time interval. At the 2-year follow-up, the groups were similar in terms of clinical assessment, patient satisfaction, function, proprioception, and isokinetic thigh muscle strength. Conclusion: Rehabilitation with the accelerated and nonaccelerated programs administered in this study produced the same increase in the envelope of knee laxity. A majority of the increase in the envelope of knee laxity occurred during healing when exercises were advanced and activity level increased. Patients in both programs had the same clinical assessment, functional performance, proprioception, and thigh muscle strength, which returned to normal levels after healing was complete. For participants in both treatment programs, the Knee Injury and Osteoarthritis Outcome Score (KOOS) assessment of quality of life did not return to preinjury levels.

Abstract:

Awareness of the possibility of multiple ligament injuries in the traumatized knee is essential for the successful management of an injured knee. Relative infrequency of occurrence, heterogeneous presentation, inconsistent treatment protocols, ambiguity in the timing of surgery, post-surgical rehabilitation protocol, and paucity of literature on the subject make the situation perplexing. This study aims at the evaluation of a multi-staged protocol and determination of various factors having influence on outcome. This study included 39 patients with injury to two or more ligaments of the knee, without associated complications. Staged protocol of ligament surgery included repair or reconstruction of collaterals and corners in the initial stage, followed by reconstruction of posterior cruciate ligament (using Hamstring graft) and anterior cruciate ligament (using Bone Patellar Tendon Bone graft). Rehabilitation included two weeks of immobilization following repair/reconstruction of collaterals/corners followed by protected range of motion exercises. In final IKDC qualification, 10 knees (25.64%) were normal (A), 26 knees (66.6%) were near normal (B), 2 knees (5.1%) were abnormal (C), and 1 knee (2.56%) was severely abnormal (D). Our staged management protocol had good subjective, and objective outcomes, and nearly all patients, but two, returned to their routine activities.

Abstract:

A 67-year-old male underwent bilateral total knee replacement surgery and was subsequently placed on a bilateral isokinetic knee rehabilitation program. Isokinetic knee testing was performed on unilateral dominant (UD; right) and nondominant (UND; left) limbs as well as bilateral limbs (BLs) before and after a three-times-per-week, 8-week protocol during which the patient followed a bilateral isokinetic velocity spectrum (60 to 300°/s) rehabilitation program. The protocol was made possible by the introduction of a new bilateral isokinetic knee attachment developed by the authors. The BL extension and flexion peak torque increased 41% and 51% at 60°/s, respectively. The UD and UND extension peak torque increased 22% and 37%, respectively, while flexion peak torque increased 68% and 52%, respectively. The bilateral deficit decreased with increasing velocity for both extension and flexion. These results demonstrate that a bilateral isokinetic approach to rehabilitation may be a legitimate technique to increase knee extension and flexion peak torque both unilaterally and bilaterally following bilateral total knee replacement surgery.

Abstract:

The research aimed at designing a rehabilitation program using electric stimulation for rehabilitating knee joint working muscles as a result of ACL tear using an apparatus developed by the researchers that stimulate the muscle vibration and work as well as the ability to rehabilitate the join in shorter periods. In addition to that, it aimed at identifying the effect of this program on rehabilitating the knee joint working muscles. The researchers used the experimental method on Baghdad clubs’ players who suffer from complete knee joint ACL tear aged (19 – 24) years old. The results showed that the training program developed the working muscles significantly achieving normal levels of activity.

Abstract:

Abstract Background and Purpose. Although weight-bearing (WB) exercise and increased hamstring muscle activity may contribute to knee joint stability in knees with an injured anterior cruciate ligament (ACL), the relationship among ACL integrity, muscle activity, and joint surface motion is not fully understood. The purpose of this study was to investigate whether knee joint rolling and gliding movements and electromyographic (EMG) activity differed between subjects with injured ACLs and subjects without knee pathology. Subjects. Fifteen subjects with injured ACLs (9 men and 6 women; mean age=26 years, SD=7, range=18–36) and 15 age- and sex-matched subjects without knee pathology (9 men and 6 women; mean age=25 years, SD=6, range=18–36) participated in the study. Methods. Sagittal-plane knee joint rolling and gliding movements and lower-extremity EMG activity were measured during non-weight-bearing (NWB) and WB movements. Mixed-model analyses of variance were conducted to analyze rolling and gliding and EMG data. Results. During NWB knee extension, greater joint surface gliding occurred in knees with injured ACLs at full knee extension. During WB knee extension, greater gliding occurred in knees with injured ACLs throughout the range of motion tested. No differences in EMG activity occurred between groups. Discussion and Conclusion. The results suggest that, in the absence of increased hamstring muscle activity, anterior tibial displacement is not reduced in knees with injured ACLs during WB movement.

Abstract:

Background: Following Total Knee Arthroplasty (TKA) patients experience lower extremity muscle weakness and commonly require physical rehabilitation to enhance functional outcomes and overall recovery.1 In Australia, there are recognised variations in rehabilitative care following TKA, however rehabilitation most commonly provided is in an outpatient setting, on a one-to-one treatment basis.2 Outpatient physiotherapy is beneficial as the physiotherapist can monitor progress and modify therapy, however such methods are resource- intensive and impose a significant cost burden.1 The number of TKA procedures is rising, bringing concern of the sustainability and economic impact of one-to-one rehabilitation. Further research is needed to determine whether outpatient physiotherapy yields superior outcomes compared to less-costly alternatives such as group or home-based rehabilitation. The Maxm skate is a portable, lower limb post-operative and post-injury rehabilitation exercise device for individual use in a hospital or home-based setting. The Skate intends to facilitate rehabilitation and conditioning through graded therapeutic exercises and minimal joint loading. Study investigators aim to conduct a randomised controlled trial (RCT) to compare the safety, efficacy and cost-effectiveness of the Maxm Skate rehabilitation device to standard rehabilitative care. The primary outcome is to assess the range of motion (ROM) achieved by patients whom received the Maxm Skate device compared with standard care, 3 months postoperatively. Methods: This is a study protocol for an open-label RCT, in which 116 participants will be randomly allocated to an interventional or control group. A total of 58 participants per group will provide 90.0% power (α=0.05) to detect 10 degrees of difference (SD=16) in ROM, at 3 months post TKA. Participants assigned to the interventional group will receive the Maxm Skate in addition to standard care in the in-patient setting. Following discharge, participants will be asked to limit physiotherapy to Skate use only, and compliance will be documented. Outcomes will be compared to those receiving standard rehabilitative care. A blinded physiotherapist will evaluate functional outcomes preoperatively and at 2, 4, 6, 12, 26 and 52 weeks post TKA. The functional assessment will include measures of knee ROM, pain, isometric knee strength, balance, and knee/thigh circumference. Limited measures will also be assessed at Day 2 postoperatively by an alternate, un-blinded physiotherapist. Clinical and patient-reported outcome measures will be administered preoperatively, and at 6, 12 and 52 weeks postoperatively. An economic evaluation assessing the relative cost-effectiveness of the Maxm Skate rehabilitation device, compared to standard care, will be conducted. Patients will also be screened for adverse event occurrences and complications from the time of consent to 1 year postoperatively. Discussion: This clinical trial is the first developed to assess the efficacy of the Maxm Skate on patient’s rehabilitation following TKA.

Abstract:

Objective:In this study a numerical model of a skier was developed to investigate the effect of different rehabilitation strategies after anterior cruciate ligament (ACL) rupture.Methods:A computer model using a combined finite-element and multibody approach was established. The model includes a detailed representation of the knee structures, as well as all major leg muscles. Using this model, different strategies after ACL rupture were analyzed.Results:The benefit of muscle training to compensate for a loss of the ACL was shown. The results indicate that an increase of 10% of the physiological cross-sectional area has a positive effect without subjecting other knee structures to critical loads. Simulating the use of a hamstring graft indicated increasing knee loads. A patellar-tendon graft resulted in an increase of the stress on the lateral collateral ligament.Conclusion:Muscle training of both extensors and flexors is beneficial in medical rehabilitation of ACL-deficient and ACL-reconstructed knees.

Abstract:

Knee instability is a common condition found in degenerative knee osteoarthritis. The evolution of the disease is a chronic one, with acute exacerbations that accentuate the static and dynamic deterioration of the knee joint. Women are more susceptible in 70% - 80% of cases, with an increased frequency after menopause, between 40 to 70 years, being often associated with obesity and varicose veins. Starting from these data and then extrapolating with the increased number of people coming to treatment with this condition, we considered that a more in-depth study theoretically, but especially practical, in terms of the effectiveness of physiotherapy treatment is slowing down the evolution of the disease. Based on the objectives we presented earlier, we are determined to focus our efforts on this category of patients, and through our study we try to find new ways to reduce the suffering of the patients and to ensure the sustainability of the obtained results.

Abstract:

The majority of soft pneumatic actuators for rehabilitation exercises have been designed for adult users. Specifically, there is a paucity of soft rehabilitative devices designed for infants with upper and lower limb motor disabilities. We present a low-profile vacuum-powered artificial muscle (LP-VPAM) with dimensions suitable for infants. The actuator produced a maximum force of 26 N at vacuum pressures of −40 kPa. When implemented in an experimental model of an infant leg in an antagonistic-agonist configuration to measure resultant knee flexion, the actuator generated knee flexion angles of 43° and 61° in the prone and side-lying position, respectively.

Abstract:

Background: There is a need for a prosthetic knee joint design that is technologically and functionally appropriate for use in developing countries.Objectives: To develop and clinically evaluate a new type of stance phase controlled prosthetic knee joint that provides stance phase stability without inhibiting swing phase flexion.Study design: A crossover repeated measures study design comparing the new knee joint to the participant's conventional low- or high-end prosthetic knee joint.Methods: The new knee joint was fitted to fourteen individuals aged 15 to 67 years with unilateral lower limb amputations. Walk tests were performed to measure walking speed. Energy expenditure was estimated using the physiological cost index (PCI).Results: Walking speeds with the new knee joint were on average 0.14 m/s faster than conventional low-end knees ( p < 0.0001), but 0.07 m/s slower than conventional high-end prosthetic knees ( p = 0.008). The PCI was similar across all three knee joint technologies ( p = 0.276).Conclusions: Mobility function with the new knee joint, in terms of walking speed, was more closely matched to high-end than low-end prosthetic knee joints. Therefore, given its relatively simple design, the new stance phase control mechanism may offer a functional and cost effective solution for active transfemoral amputees.Clinical relevance This paper describes a new type of prosthetic knee joint mechanism that is intended to be cost-effective while providing high-level stance phase function to active individuals with a transfemoral amputation. Initial clinical testing suggests that the new knee joint may have some functional advantages over existing technologies in this category.
