Five-Strand Versus Four-Strand Hamstring Autografts in Anterior Cruciate Ligament Reconstruction-A Prospective Randomized Controlled Study.

Purpose: To compare the clinical outcomes of the routine use of 5-strand hamstring grafts (where possible) with those of 4-strand grafts in primary anterior cruciate ligament (ACL) reconstruction.

Methods: A total of 64 patients were enrolled in a prospective randomized controlled study comparing the use of 5-strand and 4-strand semitendinosus-gracilis autografts in single bundle ACL reconstruction (n = 32 in each group). Four participants in each group were lost to follow-up and were excluded from the outcome analysis.
