Total Knee Arthroplasty (TKA) is now a proven and reliable treatment for severe osteoarthritis of knee joint with the incidence of the same increasing day by day.
Material and Methods: 60 patients with primary osteoarthritis knee were included in the study between February 2013 and June 2015 at a tertiary care hospital in Mumbai city. Revision cases, Post-traumatic and Inflammatory arthritis were excluded from the study.
Results: Clinical, functional and radiological outcome were assessed by Knee Society Knee Score. Paired T-test and Pearson correlation co-efficient formula were used. The mean pre-op Knee Clinical Score (KCS) was 28.28 which improved to 94.23 post-operatively. 52 patients (86.67%) had excellent results and 08 patients (13.33%) had Good results. The mean pre-op Knee Functional Score (KFS) was 41.67 in this study which improved to 87.33 post-operatively. 50 patients (83.34%) had Excellent, 08 patients (13.33%) had Good and 2 patients (03.33%) had Fair results respectively. KCS and KFS were found to be statistically significant (P<0.001).The value of R2 co-efficient of determination was 0.5938(P<0.00001).
Conclusion: Total Knee Arthroplasty improves the functional ability of the patient and gets him back to the pre-disease state, which is to have a pain free mobile joint, as reflected by the improvement in the post-op KCS and KFS.
