Functional Outcome was studied at one year following anatomical reconstruction of anterior cruciate ligament using quadrupled semitendinosus tendon autograft in patients who had presented with symptomatic torn anterior cruciate ligament.
Methods: Thirty skeletally mature patients with anterior cruciate ligament tear confirmed by Lachman Test, with or without concomitant meniscal injury underwent Arthroscopic anterior cruciate ligament reconstruction using quadrupled semitendinosus autograft, provided that they were permitted to undergo rehabilitation for six months post operatively. Single surgeon performed all surgeries and functional outcome was assessed periodically till one year followup.
Results: In our study of 30 patients with minimum one year follow-up, the IKDC score was normal in 70%, near normal in 23.3% and abnormal in 6.6%. 21 patients were very satisfied and rest 7 patients were satisfied as per SQ scoring. Before surgery affected leg hop test had mean of 42.36 with SD 10.19 and it increased postoperatively to 76 with SD of 19.93 which is statistically significant (p<0.001).Limb Symmetry Index scores significantly increased to mean±SD of 82.01±7.25 postoperatively from mean±SD of 45.88±6.94 preoperatively. Lachman upto grade one laxity observed in 56.67% patients but with hard end point, which is the reason of success of surgery.
Conclusion: The functional outcome of arthroscopic single bundle anatomical anterior cruciate ligament reconstruction with quadrupled semitendinosus tendon autograft is excellent to good (93%).
