Abstract:

Background: In an effort to improve the strength and stiffness of anterior cruciate ligament grafts, several authors have advocated alterations of graft structure and orientation, including braiding the tendons in hamstring tendon grafts. Hypothesis: Braiding hamstring tendons does not increase graft strength and stiffness. Study Design: Controlled laboratory study. Methods: Sixteen hamstring tendon and 21 bone-patellar tendon-bone grafts were harvested from 12 cadavers and divided into three groups: 1) braided four-strand hamstring tendon, 2) unbraided four-strand hamstring tendon, and 3) bon

Abstract:

The purpose of this study was to compare two different methods of joining tendons of similar and dissimilar sizes between recipient and donor tendons for flexor tendon grafts. Flexor digitorum profundus (FDP) and peroneus longus (PL) canine tendons were harvested and divided into four groups. The repair technique we compared was a step-cut (SC) suture and a Pulvertaft weave (PW). FDP tendons were significantly larger in diameter than PL tendons ( p < 0.05). The volume of the SC repairs using either FDP or PL tendon as a graft was significantly smaller than PW repairs ( p < 0.05). The ult

Abstract:

Background: The quadriceps tendon is becoming a popular graft option for anterior cruciate ligament (ACL) reconstruction. Few studies have examined the biomechanics of the quadriceps tendon compared with more commonly used graft choices. Due to the risk associated with small-diameter hamstring tendon grafts, various modifications of hamstring tendon preparation techniques have been described—specifically, a tripled, 6-strand hamstring tendon construct. This is the first study to directly compare the biomechanical properties of quadriceps tendon and hamstring tendon grafts. Purpose/Hypothesis:

Functional results of simultaneous reautoplasty of finger flexor tendons with the graft from the tendon of superficial flexor of injured finger (38 cases) versus the graft from the tendon of extensor digitorum longus pedis (74 cases) were evaluated. The conclusion was made that use of extrasynovial grafts from tendon of extensor longus of second-fourth toe was to be preferred: the rate of excellent results was by 15% higher (t=1.5), satisfactory results 2 times lower (t=1.2), the rate of graft detachment was 4 times lower (t=1.8) in comparison with plasty using intrasynovial grafts.

Partial width tendon grafts are commonly used in upper limb reconstructive surgery. Different techniques are described to harvest the graft including a "cheese wire" technique to split the tendon along its fibres with a filament. However no study has looked at the best material for this purpose. Fresh flexor tendons from pigs' trotters were used to analyse the splitting qualities of 11 different suture materials. The qualities assessed were: whether the suture material was successful in splitting the tendon, the average force required to split the tendon and the resulting quality of the spilt

Abstract:

Comparative studies have shown that bone-bone union develops faster than a junction between grafted tendon and bone, and would thus allow earlier post-operative movement, limiting adhesion formation. In this context the nature of the insertion of the plantaris tendon into the calcaneus is reviewed as a possible source of composite bone-tendon grafts. It is proposed that the composite plantaris tendon with its bony block attachment is inserted through a hole in the distal phalanx of the finger creating an immediate firm distal fixation.

Abstract:

Hamstring grafts are the most often grafts used for ACL reconstruction procedures. Especially in Asia, hamstrings are preferable since small incision for taking the graft, and not produce anterior knee pain during kneeling, since there is no bony part taken. However, sometimes hamstring is too small for the graft. Many literatures mention that at least 7-8 mm needed for the best result of ACL reconstruction using hamstring tendon. It is not easy to predict the size of the hamstring tendon before surgery. Quadriceps tendons are good alternative as the grafts for ACL reconstruction. However, som

Abstract:

An increase in anterior laxity following reconstruction of the anterior cruciate ligament (ACL) can result from lengthening of the graft construct either at the sites of fixation and/or between the sites of fixation (i.e., graft substance). Roentgen stereophotogrammetric analysis (RSA), which requires that radio-opaque markers be attached to the graft, has been shown to be a useful technique in determining lengthening in these regions. Previous methods have been used for attaching radio-opaque markers to the graft, but they all have limitations particularly for single-loop grafts. Therefore, t

The flexor digitorum profundus tendon in 11 digits with division of both flexor tendons in zone 2 was reconstructed with a palmaris longus tendon graft in a two-stage procedure. The distal and proximal fixation of the graft was reinforced with a polyester mesh sleeve placed around the ends of the graft during stage 1. All digits were mobilized with a combination of active extension and active and passive flexion within 3 days of the second stage. There were three ruptures, one due to faulty technique and two due to falls on outstretched hands during alcohol intoxication and football. Excluding

Introduction: Preoperative estimation of graft parameters can be useful while using hamstring grafts in knee ligament surgeries. Anthropometric parameters may be an easy way to predict the length and diameter of hamstring tendons. A prospective study was conducted to find the correlation between different anthropometric parameters and activity level of the patient on the length and diameter of the graft. Separate regression equations for males and females were also derived for easy prediction. Methods: Data were obtained from 95 patients who underwent arthroscopic anterior cruciate ligament re

Abstract:

Uncomplicated healing of grafts for tendon reconstruction remains an unsolved problem in hand surgery. Results are limited by adhesion formation and decreased strength properties, especially within the tight fibro-osseous sheath of the digits. This is especially problematic when an extra synovial tendon graft is used to replace an intra synovial flexor tendon. Compositional differences are likely to play an important role in these processes. The aim of this study was, therefore, to compare protein expression in pair-matched intra synovial tendon grafts with extra synovial tendon grafts, using

Abstract:

Despite recent developments in anterior cruciate ligament (ACL) reconstruction techniques, there are still several intraoperative factors affecting clinical outcomes that remain widely debated. Among such factors, graft selection might be the most critical yet controversial question for surgeons. As the primary factor influencing a patient’s choice for the ACL graft is surgeon recommendation, surgeons have to consider several factors to select the best graft for each patient. Graft options currently include autograft, allograft or synthetic grafts. In terms of autograft, there are three main o

Abstract:

To minimize adhesions following tendon repair, early post-operative movement is recommended. This has proved difficult with tendon grafting because of weakness of the repair sites, particularly distally, and because of slow revascularization. A potential solution is the use of a composite tendon-bone graft in which a bone block is attached to the end of the tendon. The tendon is threaded through a hole in the distal phalanx from the dorsal to the palmar side and impacted like a cork to create an immediate strong fixation. The tendon itself is then tunnelled through the pulley system and the pr

Various graft materials have been used in posterior cruciate ligament (PCL) reconstruction. However, it is unclear if these grafts can reproduce the structural behavior of the PCL. This paper analyzed the effect of graft length on the structural behavior of the graft using a minimal deformation energy method. An analytical solution was obtained to determine the optimal effective graft length that can best reproduce the structural behavior of the PCL. This optimal graft length was determined as a function of the axial rigidity of the graft. Two typical grafts, bone-patella tendon-bone (BPTB) an

In clinical practice, it is observed that the hamstring tendon graft, despite being first choice in knee ligament reconstruction, may not present adequate size. Therefore, it becomes necessary to search for other graft alternatives. In this context, the peroneus longus tendon arises as an option to replace or complement other grafts. The surgeon can opt to use the tendon in its totality or only its anterior half, presenting adequate length, diameter, and biomechanics, without major repercussions for the donor site.

AbstractThe incidence of anterior cruciate ligament (ACL) injuries is rising every year. The autologous hamstring tendon graft, using semitendinosus tendon (SMT) and gracilis tendon (GR), is a common repair technique in the management of ACL injuries due to its multiple advantages. Using a final graft with a minimum diameter of 8 mm is necessary to avoid graft failure. The aim of this study was to find a correlation between preoperative ultrasound (USG) measurement of the SMT and GR tendon diameters (SMTd and GRd) and their actual diameters measured during the grafting procedure.
