A STUDY OF PRIMARY TOTAL KNEE ARTHROPLASTY (TOTAL KNEE REPLACEMENT) IN SEVERE DEGENERATIVE OSTEO ARTHRITIS OF KNEE

Abstract

AIM: To assess the clinical outcome, to study radiological variable inuencing the outcome of total knee arthroplasty and to identity patient variable which signicantly inuence the outcome. Out MATERIALS&METHODS: of the 30 Arthroplasties performed in 28 patients with in the study period. 5 patients (5 knees) were lost to follow-up for various reasons and thus 23 patients (25 knees) were available for clinical review. The mean age of the patient RESULTS: at the time of surgery was 61.04 years. 76% of Knee had primary osteoarthritis and 25% had secondary OA. The average post-operative alignment as 4.3º valgus (range, 3º varus-10º valgus), the mean posterior slope of tibia (s) was 3.5º (range, 0-8º)c and the average femoral exion angle (?) 7.6º. In the assessment of post CONCLUSION: operative outcome of total knee arthroplasty, Knee Society Score is a very useful tool. Restoration of normal alignment of valgus (6 + 2º) is possible with conventional (without computer assisted navigation) surgical technique.
