BACKGROUND Twisting and braiding of four-strand hamstring tendon grafts used for anterior cruciate ligament reconstruction has been proposed, but not proven, as a method of improving tensile properties. HYPOTHESIS Twisting and braiding four-strand human hamstring tendon grafts will have no significant effect on initial graft strength or stiffness. STUDY DESIGN Paired in vitro biomechanical ...

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...

Background: Hamstring and peroneus longus tendon auto graft has similar biomechanical strength. Peroneus is a potential in reconstructive orthopaedic procedures. There was few study evaluation of usage ACL reconstruction. We aimed to quantify the outcome donor site morbidity reconstruction using graft.Methods: Patients who suffered isolated injury were enrolled underwent trans-portal single bun...

BACKGROUND Bone-patellar tendon-bone (bone-tendon-bone) and four-strand hamstring tendon grafts (hamstring) are the most commonly utilized autografts for primary anterior cruciate ligament (ACL) reconstruction. Existing clinical trials, registry studies, and meta-analyses offer conflicting opinions regarding the most favorable graft choice. QUESTIONS/PURPOSES Which graft type for ACL reconstr...

BACKGROUND Recent clinical investigations have identified inadequate autograft hamstring graft diameter (<8 mm) to be predictive of failure after reconstruction of the anterior cruciate ligament (ACL). PURPOSE/HYPOTHESIS The objective of this study was to determine the utility of preoperative magnetic resonance imaging (MRI) variables of the hamstring tendons for the prediction of graft diame...

Background: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament(ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sportsthat need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in thisarea, we designed this prospect...
