Fixed flexion deformity at knee is common in osteoarthritic knee and is a combination of bony deformity, capsular and ligamentous deformity. It affects knee biomechanics in terms of increased forces at the patellofemoral and tibiofemoral joint. This in turn makes carrying out of routine daily activities like walking or use of staircase very difficult. Therefore, it is essential to correct this deformity at the time of operative intervention. Major interventions like posterior capsular release and removal of osteophytes and adequate bony resection helps in correcting the deformity. Post operatively, use of extension night splints and adequate physiotherapy can help in correcting the residual deformity left over at the time of knee arthroplasty.
