Study of functional and radiological outcome of total knee arthroplasty using the knee society score

Abstract

The common causes of arthritis of the knee include Osteoarthritis (OA), Rheumatoid Arthritis (RA), Juvenile Rheumatoid Arthritis, Post traumatic Arthritis or secondary Osteoarthritis and other types of inflammatory arthritis. Osteoarthritis is thought to be the most prevalent chronic joint disease. The surgical techniques have varied from soft tissue interposition arthroplasty to resection arthroplasty to surface replacement arthroplasty. In surface replacement arthroplasty different types of prosthesis were developed to address the complex knee kinematics. Total Knee Arthroplasty (TKA) is now a reliable treatment for severe arthritis. Various systems are available with specific features regarding the geometry of the components, the degree of conformity of the articulating surface and the anchoring technique. Aim: To study the clinical, functional and radiological outcome in a consecutive series of Total Knee Arthroplasty using Knee Society Score. Materials and Methods: This study was done to analyse the clinical, functional and radiological outcome of Total Knee Arthroplasty using Knee Society score using a Posterior Cruciate substituting (Indus Knee Prosthesis). A Prospective study consisting of 30 patients who consented and underwent Total Knee Arthroplasty. The follow up period was at 3 months, 6 months and 1 year. Results and Discussion: According to the Knee Society Functional Scoring system, 30 patients were assessed in this study. 16 patients (53%) had Excellent, 11 patients (37%) had Good, 2 patients (7%) had Fair and 1 patient (3%) poor results. The results were found to be comparable with other studies. Conclusion: Total Knee Arthroplasty improves the functional ability of the patient and the ability of the patient to get back to pre-disease state, which is to have a pain free mobile joint, as reflected by the improvement in the post-op Knee Clinical Score and Knee Functional Score.
