To compare the two different anterior cruciate ligament surgery tech-niques’ effect in rehabilitation and activity performance. Fifty-five pa-tients were evaluated. Twenty-seven patients with transtibial technique (TT), 28 with anatomic single-bundle technique (AT) included. Tegner Activity Scale (TAS) was performed at preoperation and follow-up. The returning time of the sport and work was evaluated at follow-up. Sin-gle-leg hop test was performed at follow-up. Outcomes were compared between the two groups. The determined length difference between the operated knee and the intact knee was compared between the two groups. Average age of TT and AT was 27.9±6.4 yr, 28.3±6 yr, respec-tively. There was a significant difference between the two groups in du-ration of returning to sport. TT group had higher duration to return to sport (P<0.01). No difference between the two groups in duration of re-turning to work (P>0.05). There was a significant difference between the two groups. TT group had significantly higher values than AT group (P<0.01). No difference in TAS between the two techniques at preoper-ation and at last follow-up (P>0.05). The increase of TAS in patients who had AT was higher than the patients who had TT (P>0.05). No dif-ference in single-leg hop test at 55%–65%, 65%–75%, and 85%–95% level (P>0.05). In this test at 75%–85% TT group had higher values than AT group (P<0.05), AT group had higher values at 95%–105% level (P<0.05). Good short and long-term knee outcome scores depend on rehabilitation protocol after surgery. Surgery technique should provide the adequate stability in rehabilitation period. AT obtains better out-comes in rehabilitation.
