Krishna L, Chan CX, Lokaiah L, et al. - This two-year's follow-up study was intended to compare the clinical outcomes of the routine use of 5-strand hamstring grafts (where possible) with those of 4-strand grafts in a primary anterior cruciate ligament (ACL) reconstruction. A prospective randomized controlled study of a total of 64 patients was conducted to correlate the use of 5-strand and 4-strand semitendinosus-gracilis autografts in single-bundle ACL reconstruction (n=32 in each group). This study's findings demonstrate that the routine use of the 5-strand hamstring tendon autograft was not superior to that of the quadrupled or 4-strand graft in primary ACL reconstruction at the 2-year follow-up.
