Although being debated for many years, the superiority of Posterior Cruciate-Retaining (CR) Total knee Arthroplasty (TKA) and Posterior Cruciate Stabilizing (PS) TKA remains controversial. The primary objective of this study was to compare functional outcome in patients who underwent primary total knee arthroplasty surgery using posterior stabilized and cruciate retaining implants. Material and method: Sixty diseased osteoarthritis knees in 42 patients were included in the study, with 30 cases (Knees) operated with CR prosthesis and 30 cases (Knees) with PS Prosthesis. The two groups were then compared using disease specific functional scores; 2011 knee society score. Pain, range of motion, any flexion, varus, valgus deformity, instability at knee joint was assessed preroperatively and postoperatively. Functional outcome (e.g. walking, climbing stairs) was assessed. Result: Postperative objective knee score and range of motion was significantly better in PS group than CR group, with significant p value. No significant difference in functional outcome between both the groups was
