Osteoarthritis gradually leads to a flexion deformity which could be attributed to either soft tissue contractures or bony blocks due to proliferating abnormal osteophytes after which surgical intervention is advocated. The different surgical options which exist are high tibial osteotomy, proximal fibular osteotomy, and knee replacement which could be unicondylar or Total. Amongst all these Total Knee replacement (TKR) provides a way to overcome all afflictions of arthritis. A prospective study was conducted in the department of orthopaedics in S.C.B medical college & hospital from October 2018 to October 2020 in 30 Patients who presented with a flexion deformity of the knee due to osteoarthritis. The mean age of the patients was 55.8±6.25 years (range 44-69). The disease is more common in the geriatric age group patients with the highest proportion (36.67%) cases in the 56-60 years age group. The male to female ratio was almost 1:2. The left knee was found slightly more affected 16(53%) than the right knee 14 (47%). Most of the patients 18 (60%) were in KL Stage III Osteoarthritis which signifies the negligence on part of the patient in seeking early medical care. The mean knee range of motion in flexion was 86.6⁰ ± 10.5⁰ (range 68-110). Additional Varus deformity was seen in 10 (33.3%) cases. No cases of valgus deformity were found in our study. The difference between the means of pre and post-op FFD is 21.9(18.37-25.42, 95% CI). The difference between the means of pre and post-op scores is 41.3 (35.0-47.5, 95% CI). The difference between the means of pre and post-op scores is 43.19 (37.0-49.3, 95% CI). In an Indian scenario where the patient comes late with gross varus and fixed flexion deformity, Posterior Cruciate Sacrificing Total Knee Replacement will give greater mobility and stability, so it can be the preferred mode of management. This implies the universality of Total Knee Arthroplasty as the Gold standard in the treatment of Osteoarthrosis of knee cutting across demographic variation and socio-economic distributions.
