Abstract

Background: Total joint arthroplasty are simple to relieve pain, to provide motion while maintaining stability and to correct deformity. Current total joint prosthesis which is properly implanted, consistently achieve excluding high success rates, in meeting these goals in both short term and long term follow up studies. The aim of this study is to analyze the functional outcome of fixed bearing total knee arthroplasty. To assess the functional outcome in patients undergoing total knee arthroplasty using knee society knee score system. Materials and Methods: This study was conducted in a tertiary care set up. This is a Prospective study conducted during the period of June 2009 – September 2014. Study includes 40 patients who underwent total knee Arthroplasty in 40 knees. Post traumatic arthritis patients were excluded from the study. Results and Discussion: In this study except two patients all others showed an improvement in knee score. Among those, 39 patients had excellent scores (85-100), 1 patients had good score (70-84). The mean increase in Knee score was 48.17. In our study we observed that the return to function is excellent to good at the follow up. All our patients showed an improvement in knee score except two. 19 patients had excellent scores (85-100), 1 patients had good score (70-84), 0 patients had fair results (60-69) and 0 had poor results. The mean increase in Knee score was 48.17. The function score was also improved from 19.75 in the preoperative period to 80.82 in the postoperative period. Conclusion: From this study it can be concluded that, the average postoperative range of movement improved to 101.89 degrees from the preoperative range of 92.7 degrees. The mean preoperative Knee society knee score was 36.03, while the mean postoperative score was 84.2 indicative of the overall good functional outcome.
