Results, clinical outcome and analysis of non-patella resurfacing total knee arthroplasty in osteo arthritis knee

Introduction: There is no difference in clinical and functional outcome after total knee arthroplasty (TKA) for knee osteoarthritis between patellar resurfacing and non-resurfacing. Thus, we have performed this study to evaluate the outcome of non-patella resurfacing total knee arthroplasty. Materials and Methods: A total of 50 patients in series who came to our institute with clinical signs and symptoms of osteoarthritis confirmed radiologically, were operated. We measured the outcomes with Knee society score and VAS score. Results: There was significant difference in outcome of non-resurfaced patella pre-operatively and post-operatively. There was significant improvement in mean range of motion (ROM) 87.2 pre-op vs 104.4 post-op, KSS pre-op mean 39.66 vs post op mean 83.26. The improvement in functional score were pre-op 52.5 to post-op 83.36. The mean VAS score decreased from 7.98 to 2. Conclusion: The results showed significant difference in knee society score and VAS pre-operatively and post-operatively. Keywords: Non-patellar resurfacing, Osteoarthritis, Total knee arthroplasty.
