Abstract

Hamstring tendons have become the most accepted grafts for ACL reconstruction. Harvesting only semi-T instead of SemiT-G from the pes anserinus can reduce the deficit of the knee flexor strength and improve the functional recovery without weakening the reconstructed ligament. A Retrospective study was conducted on 63 patients who underwent anatomical ACL reconstruction using tripled semitendinosus graft fixed with interferential screws. The average length of the Semitendinosus graft was 25cm. The cases had an average follow up upto 24 months. Functional evaluation informs radiological laxometry and objective knee scores in the forms of IKDC, Lysholm and Tegner scores. The mean Lysholm score improved from 49 (35-65) pre-op to 86 (55-100) on follow-up. The Tegner score improved from 4+1 to 5+1. The IKDC(International knee documentation committee) score improved from pre-op A=2cases, B=7, C=15, D=39 to Post-op A=28, B=22, C=10, D=3 respectively. 4 cases have pivot shift positive (6%) including 3 cases of traumatic graft ruptures at a mean age of 9.3 months. After radiological laxometry, 48 cases have anterior laxity <3mm, 6 cases have 3-5mm and 4 cases have >5 mm laxity. Tripled ST graft is an adequate graft for ACL reconstruction in the Indian population, considering the varied anthropometry and squatting habit. It obviates the need for harvesting the gracilis, yet retains adequate strength for use as an ACL graft.
Keywords: Tripled Semi Tendinosus graft; Knee scores; Gracilis.
