Background Osteoarthritis of knee (OAK) is a chronic and major disease affecting geriatric population, characterized by the breakdown of joint cartilage. Arthritis of the hip and knee is the 12th highest contributor to global disability and the 38th highest contributor to disability-adjusted life years. The management includes amalgamation of pharmacological action, surgery as well as osteotomy, arthroplasty, stem cell therapy & physiotherapy. AIMS To evaluate the influence of posterior condylar offset on range of movements following a total knee Arthroplasty. Further, to assess the functional outcome following a total knee Arthroplasty according to Knee Society Score. Methodology A prospective hospital-based study with 40 patients was conducted. Patient will then undergo surgery and post operatively, all patients will be subjected to an x-ray to measure the posterior condylar offset. Post operatively all patients were be subjected to x-ray imaging and evaluated clinically at 3 weeks, 3 months and 6 months for the range of movements and Knee Society Score. Results In this study, 11 patients were male and 29 were females. Subject distribution as per the outcome result after treatment; into good, fair and excellent with 25, 2 and 13 subjects respectively. The pre and post-operative mean PCO value with it being 26.4 ± 1.9 and 26.0 ± 1.9 and pre and post-operative mean PCOR value with it being 0.44 ± 0.1 and 0.45 ± 0. It was found to be statistically significant. Conclusion The flexion angle after Knee Arthroplasty is predictor of the functional outcome as well as its prognosis over the long-term. Posterior Condylar Offset as well as Posterior Condylar Offset Ratio is key variable for the assessment of knee function. It is important to consider other variables to predict the associated complications as well as outcome of the disease process.
