BACKGROUND Tendon disorders are common problems in sports and are known to be difficult to treat. Only limited information is available concerning treatment of proximal hamstring tendinopathy. To the authors' knowledge, no histopathologic findings of proximal hamstring tendinosis have been published. HYPOTHESIS Surgery (semimembranosus tenotomy and exploration of the sciatic nerve) is an effe...

BACKGROUND The use of validated outcome questionnaires and magnetic resonance imaging (MRI) when assessing outcomes after surgical treatment of proximal hamstring avulsions has been limited. PURPOSE To comprehensively evaluate clinical, functional, and radiological outcomes in patients treated with surgical repair for complete proximal hamstring avulsions. STUDY DESIGN Case series; Level of...

The Four-Strand Hamstring Tendon Autograft has been long established as the gold standard for surgical reconstruction of the Anterior Cruciate Ligament. Some studies have suggested wider grafts, such as a Five-Strand hamstring graft, may provide greater strength and a larger scaffold for incorporation of the graft into the bone tunnels, leading to greater postoperative anterior stability of the...

INTRODUCTION: The hamstring tendon autograft is widely used for anterior cruciate ligament reconstruction because of its superior tensile strength and lower donor site morbidity. The successful reconstruction surgery depends on not only initial graft fixation but also biologic integration of the graft. The healing process of transplanted tendon graft to bone via the development of fibrovascular...

Only 20 years ago reconstruction of the anterior cruciate ligament (ACL) involved an open intra-articular operation in which the graft was placed in a position where it was not anatomical and which involved opening both the medial and lateral capsules. There was a long scar and considerable analgesia was required after the operation. The patient remained in hospital for ten days and in a cast f...

Increased stability has been reported with both autografts and allografts for anterior cruciate ligament (ACL) reconstruction. However, meta-analysis has shown significantly lower overall knee stability rates and more than double the abnormal stability rate with allografts. Some issues surrounding allograft sterilization (ie, risk of disease transmission) are unresolved, and cost is also a conc...
