Abstract:
The purpose of this study was to assess the knee strength and anterior laxity in between primary and revision anterior cruciate ligament (ACL) reconstruction. It was a cross-sectional study; 28 patients who had undergone revision ACL reconstruction and the another 30 patients who had primary ACL reconstruction once were compared each other which they all had been operated during the same period of season with the same technique in the same hospital. The isokinetic equipment was used to measure the main outcome for knee strength, and KT-2000 arthrometer was used for measuring anterior drawer test in 12 months post-reconstruction surgery. In the anterior drawer test, we found out that there were significantly differences between primary and revision ACL reconstruction groups (1.5±1.1 mm vs. 2.6±1.5 mm, p=0.001). There was no significant difference in the deficits of knee extensor and flexor muscle strength between primary and revision ACL reconstruction. Revision reconstruction groups have more laxity in anterior drawer than primary reconstruction groups. After revision ACL, the deficits of knee extensor and knee flexor muscle strength have no significantly difference from primary ACL reconstruction.
