Few studies have been reported on the longitudinal comparison of recovery patterns between patellar tendon graft(PT) and hamstring tendon graft(HS) for anterior cruciate ligament reconstruction(ACLR). Purpose is to investigate different isokinetic recovery patterns according to graft types, and to suggest a proper rehabilitation protocol during early rehabilitation phase. Twenty two patients using either PT (n=12) or HS (n=10) were selected. All of them participated in our accelerated rehabilitation program 3 to 12 weeks after surgery. Serial isokinetic tests for the knee extension/flexion were done at 6, 8 and 12 weeks. The differences of serial comparisons were analyzed by general linear model repeated measure. Peak torque of knee extension showed similar values in PT (104.3±30.2 Nm) and HS (109.5±36.7 Nm) at 12 weeks. In knee flexion, PT group (81.0±15.5 Nm) attained greater strength than HS group (64.0±23.2 Nm). There was no significant difference in recovery pattern of peak torque in both groups. In work fatigue ratio, PT group showed faster recovery than HS group from 8 to 12 weeks. The recovery pattern of two groups in average work was significantly different. (P<0.05) In conclusion, the program in early rehabilitation phase should emphasize the endurance and power recovery of knee extensor/flexor in patients with hamstring graft.
