- Abstract
- Purpose: This study was designed to compare the preoperative strengths and endurances of the quadriceps and hamstring muscles in patients with anterior cruciate ligament (ACL) versus posterior cruciate ligament (PCL) tears. Methods: Quadriceps and hamstring muscle strength and endurance were compared between 20 prospectively enrolled patients with isolated PCL tears and a retrospective, matched control group of 20 patients with isolated ACL tears. The maximal torque (60 degrees/s) and total work (180 degrees/s) of the quadriceps and hamstring were evaluated with an isokinetic testing device. Results: Total work (1,094.4 +/- 505.8 J v 797.5 +/- 332.7 J, P = .035) and peak torque (129.9 +/- 56.2 N.m v 98.2 +/- 37.4 N.m, P = .046) of the quadriceps muscle on the involved side were higher in the PCL tear group than in the ACL tear group. However, there were no significant differences between the PCL tear group and ACL tear group in hamstring muscle strength (45.8 +/- 42.3 N.m and 46.0 +/- 24.4 N.m,respectively; P = .940) and endurance (429.3 +/- 238.9 J and 382.4 +/- 256.1 J, respectively; P = .574) on the involved side. Conclusions: The strength and endurance of the quadriceps muscle of the injured limb were greater after PCL tears than after ACL tears. However, there were no significant between-group differences in hamstring muscle strength and endurance on the involved side.
