A total of 108 patients with unilateral instability of the knee, associated with rupture of the anterior cruciate ligament, was prospectively randomised for arthroscopic single- or double-bundle reconstruction of the ligament using hamstring tendons. The same post-operative rehabilitation protocol was used for all. The patients were followed up for a mean of 32 months (24 to 36). We measured th...

We describe a case of painful snapping in the medial aspect of the knee of a 40-year-old man, following a knee hyperflexion injury. Dynamic real-time ultrasonography determined that the snapping was due to the distal tendon of sartorius passing over a medial meniscal cyst. The patient subsequently underwent arthroscopic decompression of the cyst instead of an inappropriate hamstring tendon harv...

the femur, grazing and shattering the bone, but not injuring the popliteal vessels or the hamstring tendons. Crepitus could be distinctly felt on movement of the limb, and fractured bone was felt with.the probe. The escape of synovial fluid in large quantities a few days later, showed that the fracture extended into the knee-joint, but there was no displacement of the bone or distortion of the ...

BACKGROUND Previous studies have suggested that hamstring tendons can regenerate following harvesting for anterior cruciate ligament reconstruction. HYPOTHESIS This "neo-tendon" is a true, functional tendon, not scar tissue. STUDY DESIGN Controlled laboratory study. METHODS Semitendinosus tendons were harvested from 35 New Zealand white rabbits using a standard tendon stripper. The rabbit...

BACKGROUND Although surgical repair has been reported to provide improved outcomes compared with nonoperative treatment in the management of complete proximal hamstring origin avulsions, no intact or avulsion repair biomechanical data exist to support various repair strategies or guide postoperative rehabilitation. PURPOSE To compare failure load among 4 proximal hamstring tendon conditions: ...

Background Hamstring autograft size <8 mm has been shown to be a predictor for failure after anterior cruciate ligament (ACL) reconstruction. The ability to predict graft size preoperatively is helpful in counseling patients about the possible need for graft augmentation. Purpose To determine whether preoperative ultrasound (US) measurements of hamstring tendons can predict intraoperative gra...

BACKGROUND Rotator cuff repair retear rates range from 25% to 90%, necessitating methods to improve repair strength. Although numerous laboratory studies have compared single-row with double-row fixation properties, little is known regarding regional (ie, medial vs lateral) suture retention properties in intact and torn tendons. HYPOTHESIS A torn supraspinatus tendon will have reduced suture ...

OBJECTIVE The aim of this study was to assess whether harvesting of two hamstring tendons (semitendinosus and gracilis) has the same rate of nerve injury as harvesting of the semitendinosus tendon alone, used as a triple graft. METHODS Changes in sensitivity relating to injury of the infrapatellar branch of the saphenous nerve were evaluated in 110 patients six months after they underwent ant...

PURPOSE To assess the potential therapeutic effect of intratendinous injection of platelet-rich plasma (PRP) under ultrasound (US) guidance to treat tendon tears and tendinosis in a pilot study with long-term follow-up. MATERIALS AND METHODS The study included 408 consecutive patients referred for treatment by PRP injection of tendinopathy in the upper (medial and lateral epicondylar tendons)...
