Background:Osteoarthritis (OA) of the knee is one of the leading causes of disability among adults older than 65 years. Total knee arthroplasty (TKA) is an excellent treatment option for individuals with symptomatic osteoarthritis in at least 2 of the 3 compartments of the knee and who have failed conservative treatment. Hence; the present study was conducted for evaluating the outcome of primary total knee arthroplasty. Materials &Methods:A total of 100 patients were analyzed. complete demographic and clinical details of all the patients were obtained. Only those patients were enrolled which were scheduled to undergo TKA. Inclusion criteria for the present study included patients more than 18 years of age, patients which were skeletally mature, and which were scheduled to undergo TKA. A Performa was made and details of radiographic findings of all the patients were recorded. All the patients underwent TKA under general anesthesia. Postoperative follow-up findings of all the patients were recorded. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was used for follow-up assessment. Complications were assessed on follow-up. Results:While assessing KOOS, symptoms and stiffness score was 88.3 while pain score was 85.1. Function in daily life score was 81.3 while function in sports and recreation was 30.9. quality of life score was 82.8 while global KOOS was 76.2. Complications were encountered in 12 percent of the patients. Among these two patients, arthrofibrosis was seen in 5 patients while soft tissue infection, was seen in 3 patients. Conclusion: Good functional results were obtained among patients undergoing TKA with minimal complications rate.
