Clinical profile of patients undergoing bilateral total knee replacement at a tertiary care hospital

Abstract

During standing, the joint reaction force increases with increasing knee flexion as the force vectors of quadriceps and patellar tendons become more parallel to the joint reaction force. It has been calculated, patella-femoral joint reaction forces is of 2-5 times body weight during activities of daily living; during squatting to 120 degree of knee flexion, the joint reaction force may be as high as 7-8 times body weight. During knee flexion, the patella makes a rolling or gliding motion along the femoral articulating surface. This study was conducted in Department of Orthopaedics, twenty patients who Consented (12 female and 8 male) and underwent SBTKR for tricompatrmental arthritis of knee using a posterior stabilized type of knee prosthesis, were assessed functionally using knee society score and oxford knee score. In the present study Knee society score and oxford scores were assessed in patients post operatively after simultaneous bilateral total knee replacement at 3 months, 6 months and 12 months. it was observed that the mean KSS score right knee improved from 132.9 at 3 months to 144.57 at 6 month and 159.86 at 12 months. Mean KSS score left knee improved from 133.7 at 3 months to 145.29 at 6 month and 161.1 at 12 months. Mean oxford score improved from 32.4 at 3 months to 36.76 at 6 month and 40.38 at 12 months.
