Total knee replacement (knee arthroplasty) is a surgery that replaces the knee joint with an artificial implant. Knee arthroplasties are primarily performed for clients with severe pain or mobility impairment from arthritis. Following a knee arthroplasty, the nurse must plan care to reduce the client's risk of complications while promoting comfort and recovery. Contracture of the operative joint is a serious complication of knee arthroplasty that impairs the client's mobility. To prevent contracture formation, the nurse should maintain the operative knee in an extended position with a knee immobilizer or pillow placed under the lower leg or heel. Placing a pillow behind the knee causes joint flexion, which increases the risk of contracture (Option D). (Option A) Cold packs may be applied intermittently over the operative joint to reduce postoperative swelling and pain. (Option B) Using a continual passive motion device, if prescribed, may improve range of motion through knee flexion and extension and prevent contractures. (Option C) Applying a leg immobilizer during ambulation provides support, maintains alignment, and prevents dislocation of unstable operative joints. Educational objective: Knee arthroplasty is the surgical replacement of the knee joint. Following a knee arthroplasty, the nurse should avoid placing a pillow behind the client's operative knee due to the risk of contracture. Proper postoperative care includes applying intermittent cold packs to reduce pain and edema, using a continual passive motion device for flexibility, and obtaining a leg immobilizer for joint stability during ambulation.
