Abstract: Background and Objectives: To study the functional outcome following total knee replacement in primary osteoarthritis patients with varus deformity.
Method: In our study, we had analysed the functional outcome of patients with chronic osteoarthritis of knee between the ages of 50-76 and had undergone total knee replacement in Dr PSIMS & RF, Chinnaoutpalli. Out of 26 patients who had undergone knee replacement 15 were female patients and 11 were males. We had evaluated the functional outcome using American knee society score and documented the complications.
Results: In our study, 58% of the patients comprised of females and 42% of males. In this study 57% of patients of patients had excellent results, 33% of patients had good results, 10% of patients had fair results. Relief of pain was excellent in most patients: 86% had no pain or very mild pain postoperatively. The average post- op anatomical alignment of tibiofemoral angle was found to be 4.10 valgus on radiographic evaluation.
Conclusion: In our study, we found that total knee replacement in symptomatic primary osteoarthritis is a very effective procedure in management of pain and in regaining good range of movements. We also conclude that American Knee Society Score is a very useful tool to assess the outcome of the surgery. In our series, cemented total knee arthroplasty has demonstrated well to excellent results. Further follow-up studies are required to see if this performance is maintained in the long term results.
