BACKGROUND Our hypothesis that multiple, equally tensioned strands of hamstring graft used for reconstruction of the anterior cruciate ligament are stronger and stiffer than ten-millimeter patellar ligament grafts was tested biomechanically with use of tendons from cadavera. METHODS In the first part of the study, we measured the strength and stiffness of one, two, and four-strand hamstring g...

BACKGROUND In cases where the acetabular labrum is severely damaged and irreparable, labral reconstructions are becoming an increasingly preferred means of preserving the fluid seal effect of the labrum. However, the graft that most closely replicates the biomechanical properties of the native labrum remains undetermined. PURPOSE To characterize the tensile properties and geometry of the labr...

BACKGROUND Previous studies are contradictory in terms of the function, regeneration potential, insertion point, and cross-sectional area of the semitendinosus and gracilis tendons after harvest for anterior cruciate ligament (ACL) reconstruction. HYPOTHESES In the long term, the tendons will regenerate in most patients with a more proximal point of insertion, the cross-sectional area of the ...

To date, there is no consensus on the best technique to repair injured posterolateral structures of the knee. We evaluated the effects of a fibular head based isometric reconstruction of the posterolateral knee corner with a double bundle semitendinosus tendon. From February 2001 to February 2005, 18 isometric reconstructions of a chronic posterolateral corner (PLC) injury of the knee were perf...
