Abstract
|
|
|
The purpose of this study was to evaluate recovery of hamstring force after anterior cruciate ligament (ACL) reconstruction using hamstring tendon grafts. Sixty patients who underwent ACL reconstruction with hamstring autograft were evaluated after a minimum period of 2 years. To
analyze the functional deficit after graft harvest, the peak isokinetic torque for knee flexion were measured in sitting position and prone position using the BIODEX System III(USA). Comparing the isokinetic peak torque with unaffected knee, the number (percentage) of patients that
showed less than 15% difference in strength at 60°/sec and 240°/sec in sitting position, and hyperflexion in prone position, were 48(81.6%), 54(90%), and 5(8.3%), respectively.
Recovery of flexor strength of the knee after reconstruction of ACL with hamstring autograft may be expected for 0°-90°. However, the loss of knee flexor strength were found in injury knee of patients at high knee flexion angles.
