Abstract

Introduction: Arthritis is the most common disabling disease that affects millions of people in our India. The incidence of osteoarthritis is increasing with increase in ageing population. The purpose of the study is to prospectively study the functional outcome and radiological outcome of Total Knee Arthroplasty for severe varus deformity. Materials and methods: In our study 20 cases of arthritis knee treated with Total Knee Arthroplasty. Both cruciate retaining and cruciate substituting prosthesis were used. Out of 20 cases 8 were males and 12 females, left side is more commonly involved than right side. The outcome was measured using the knee society scoring system at 6months and 1 year. Results: In our study there is significant improvement in knee society scoring system post operatively. The average post-operative Knee Clinical Score was 91.6. The average post-operative Knee Functional Score was 86. In our study out of 20 cases anterior knee pain was noted in 6 cases, superficial infection in 2 cases which was treated with culture sensitive antibiotics and notching of anterior femoral cortex in 1 case.Conclusion: Total Knee Arthroplasty improves the functional ability of the patient and the ability of the patient to get back to pre-disease state, which is to have a pain free mobile joint, as reflected by the improvement in the post-op Knee Clinical Score and Knee Functional Score.
