Functional and Radiological Outcomes of Total Knee Arthroplasty in Osteoarthritis with Varus Deformity of Knee: A Prospective Study

Abstract

Introduction: Total knee replacement (TKR) is the most commonly performed orthopedic surgical procedure for treating severe arthritis of the knee joint either due to osteoarthritis or due to inflammatory arthropathy. There was cartilage damage in either the medial or patella femoral joint/lateral compartment. Severe pain through deformity develops, subsequently necessitating a total joint replacement. This study assessed the Functional and radiological outcomes of total knee arthroplasty in osteoarthritis with varus deformity of the knee. Materials and Methods: From February 2021 to July 2022, all patients with osteoarthritis with varus deformity of knee were subjected to total knee arthroplasty after obtaining approval from the Institutional Ethics Committee were required to enroll patients. Results: The age of the patients in our study was 63.58 years ranging from 52 to 79 years. In 72.09% of the patients were females while the remaining 27.91% were females. In our study, 45% of the patients were overweight while the remaining 59.48% were overweight. In our study, 55.81% of the patients get their left knee operated first while the remaining 44.19% of the patients get their right knee operated first. In 25.58% patella resurfacing was done. The p-value was found to be significant between the pre- and post-oper knee society scores. In our study, 5 patients had complications out of which 4.65% of the patients had superficial wound infection, 4.65% of them patient had anterior knee pain and 2.33% had popliteal artery thromboembolism. Conclusion: Total knee arthroplasty is a relatively safe procedure. Treatment with total knee arthroplasty resulted in greater pain relief and functional improvement after 6 months. It 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, There was a significant association between the knee clinical score and knee functional score at six months follow-up.
