Patellofemoral dislocations are common. In cases with recurrence or residual instability, surgical intervention is usually considered. Numerous treatment protocols have been used in the past to treat patellofemoral instability secondary to patella dislocation. Reconstruction of the medial patellofemoral ligament is one of the possible options, since it was acknowledged to have a major medial st...

BACKGROUND There are conflicting reports of allograft performance, immune response, tissue incorporation, and rerupture rates when used for anterior cruciate ligament reconstruction. PURPOSE To evaluate the clinical outcome of a fresh-frozen, nonirradiated, patellar tendon allograft for primary anterior cruciate ligament reconstruction surgery. STUDY DESIGN Case series; Level of evidence, 4...

OBJECTIVE To analyse the bone-ligament integration «ligamentization» of the tendon graft in the reconstruction of anterior cruciate ligament (ACL) performing tunnels of different diameter. MATERIAL AND METHODS We performed the same reconstruction procedure using an autologous tendon graft taken from the superficial tendon of the hoof in 41 adult sheep. In Group A the tibial and femoral tunnel...

Massive irreparable rotator cuff tears in young patients are a particular challenge for the orthopaedic surgeon. Surgical treatment options include debridement, partial rotator cuff repair, patch-augmented rotator cuff repair, bridging rotator cuff reconstruction with graft interposition, tendon transfer, and reverse total shoulder arthroplasty. Recently, reconstruction of the superior glenohum...

We present a case of disruption of the posterolateral corner of the knee with avulsion of the tendon of biceps femoris. Repair and reconstruction included an allogenic tendon graft to replace the posterior cruciate ligament. Surgery was followed by a complete common peroneal nerve palsy. Revision surgery revealed that the nerve had been displaced anteriorly by avulsion of the biceps tendon and ...

We report the incidental discovery of a flexor carpi radialis brevis tendon, a rare anatomical variant identified during a surgical procedure. Magnetic resonance imaging of the contralateral side helped to delineate the anatomy of the flexor carpi radialis tendon and to differentiate the flexor carpi radialis brevis tendon from it. We describe the use of this rare tendon in ligament reconstruct...

PURPOSE We aimed to provide anatomical data and mechanical tensile properties for the rectus femoris tendon to determine if it is a feasible substitute for the anterior cruciate ligament during knee joint reconstruction. METHODS The length and width of the quadriceps femoris tendon were measured from ten adult cadavers (20 knees; age =48±2 years). The anatomic features of the patellar inserti...

Generalized joint laxity is a genetically determined component of overall joint flexibility. The incidence of joint laxity in the overall population is approximately 5% to 20%, and its prevalence is higher in females. Recently it was noticed that individuals with generalized joint laxity are not only prone to anterior cruciate ligament injuries but also have inferior results after a reconstruct...

Clinical results of our reconstruction technique for anterior cruciate ligament using the double bundle, i.e., the combination of bone-tendon-bone (BTB) from the patellar tendon and semitendinosus tendon (ST), were evaluated. BTB was fixed in the tunnels produced on the isometric points on the tibia and femur, and ST, on the tibial tunnel through the same route as BTB. Throughout the observatio...

BACKGROUND The palmaris longus tendon is frequently used as a tendon graft or ligament replacement. In rare instances the median nerve has been inadvertently harvested instead of the palmaris longus for use as a tendon. METHODS Nineteen cases in which the median nerve had been mistakenly harvested instead of the palmaris longus tendon were collected from members of the American Society for Su...
