background: rupture of anterior cruciate ligament (acl) would cause instability and disability and if left untreated. reconstruction is performed by different techniques including patellar bone graft, as the strongest device. application of brace after acl reconstructions has revealed doubtful results.   methods: one hundred acl ruptured patients randomized into two groups were reconstructed wi...

BACKGROUND There are still controversies about graft selection for primary anterior cruciate ligament reconstruction, especially with respect to knee stability and functional outcome. HYPOTHESIS Biodegradable interference screw fixation of hamstring tendon grafts provides clinical results similar to those achieved with identical fixation of bone-patellar tendon-bone grafts. STUDY DESIGN Coh...

The purpose of this study was to compare the tensile strength of the central one third patellar tendon--as used for reconstruction of the anterior cruciate ligament--to that of the residual patellar tendon. Ten matched pairs of human cadaveric knees were used for this study, each specimen consisting of an intact patella-patellar tendon-proximal tibial unit. One knee from each pair was randomly ...

Anterior cruciate ligament reconstruction with bone-patellar tendon-bone autograft has long been considered the graft preference for young, active patients with anterior cruciate ligament injuries. The central-third of the native patellar tendon is a reliable graft and is the preferred option for competitive athletes given its excellent track record with high return-to-play rates and low failur...

BACKGROUND Although differences in mechanical properties between symptomatic and healthy tendons have been observed for the Achilles tendon, the impact of tendinopathy on patellar tendon mechanics is not fully documented. The aim of the present case-control study was to assess the mechanical properties of the tendon and jump performance in elite athletes with and without patellar tendinopathy. ...

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using the middle third of the patellar tendon is an effective method for treating ACL insufficiency. Donor site morbidities are usually mild. This article presents a case of simultaneous patellar fracture and patellar tendon avulsion that occurred 8 weeks after this operation. Such a case has rarely been reported. Theoretically...

reconstruction by means of bone-patellar-bone (BTB) autografting is an increasingly popular procedure for the stabillization of ACL-deficient knee (1, 2). The central one-third of the patellar tendon and bony plugs are excised together to increase strength, durability and elasticity (3, 4) and the donor site is allowed to heal by primary intensification. The outcome of ACL reconstruction, using...

BACKGROUND Patellar and hamstring tendon autografts are the most frequently used graft types for anterior cruciate ligament reconstruction, but few direct comparisons of outcomes have been published. HYPOTHESIS There is no difference in outcome between the two types of reconstruction. STUDY DESIGN Prospective randomized clinical trial. METHODS After isolated anterior cruciate ligament rup...

PURPOSE Patellar tendon and hamstrings are both used in anterior cruciate ligament (ACL) reconstruction, and comparisons have been reported with different results. The purpose of this clinical study was to compare the results of ACL reconstruction in athletes with 2 different graft types, both using bone-to-bone healing: bone-patellar tendon-bone graft and a quadrupled bone-semitendinosus graft...
