Postoperative care after knee arthroplasty includes progressive leg exercises to obtain 90-degree flexion as it helps to prevent stiffness and promote healing. Early ambulation with partial weight bearing is also encouraged in the first 24 hours after surgery, followed by full weight-bearing as tolerated. Bed rest and immobilization of the knee in extension for an extended period is not recommended as it can increase the risk of complications such as thrombosis and stiffness. Immobilization of the knee in 30-degree flexion for 6 weeks is also not recommended as it can lead to muscle weakness and delayed recovery.
