Observational study to evaluate functional out-come of total knee replacement in primary osteoarthritis of knee joint

Abstract

Introduction: Osteoarthritis is thought to be the most prevalent chronic joint disease. Total knee arthroplasty is now s reliable treatment for severe arthritis and is commonly done for end stage arthritis of knee. The results of TKA are predictable in majority of cases, but with geriatric population, arthritis is often associated with other co-morbid condition along with age, which makes the results of TKA less predictable. So the present study was conducted to evaluate the clinical and functional outcome of TKA in this subset population. Materials and Methods: This prospective study was done at a tertiary center of new civil hospital surat. A total of 25 Consecutive patients who consented and underwent TKA were assessed clinically, functionally using the knee society score at 6 months. Results: The average pre-op knee Functional score was 65.8 which improved to an average post-op score of 83.68 At 6 month follow up, 19 patients (76%) had excellent, 2 patients (8%) had good, 2 patients (8%) had fair, and 2 patients (8%) had poor results as per KFS. The average pre op knee Clinical score was 47.4, which improved to a post op score of 83.84. At 6 month follow up, 18 patients (53%) had excellent, 5 patients (20%) had well, 1 Patient (4%) had fair and 1 patient (4%) had poor results as per KCS. Conclusion: Total knee arthroplasty improves the functional ability of the old patient above 60 years 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.
