The purpose of the study was to identify the effects of closed chain exercise on strength of the vastus medialis obliquus (VMO) muscle and functional activities in patients with total knee replacement. 19 patients was divided by the experimental group (n=9) and control group (n=10). Experimental group was received closed chain exercise including terminal knee extension and lateral set up. Control group was received electrotherpy and continuous passive motion (CPM) for 30 min/day, 4-weeks. strength of VMO was measured by isometic contraction at knee flexion of 30° using isokinetic dynomometer. Korean-Western Ontario and McMaster University Osteoarthritis Index (K-WOMAC) was measured, There was significant difference in strength of VMO and K-WOMAC (p<.05). Comparing with control group, experimental group was more improved. Therefore, after surgery, Closed chain based strength training as early rehabilitation intervention seems to be needed for early return to the patients with total knee replacement.
