Post-hip replacement precautions?

• A. Do not bend at the hip more than 90 degrees and do not cross legs or ankles
• B. Bend beyond 90 degrees and cross legs
• C. No restrictions
• D. Only avoid knee flexion

Answer: (A)

After a hip replacement, protecting the new joint from dislocation is the priority. The movement guidelines aim to keep the hip in a safe position during healing by limiting how far the hip can bend and by preventing crossing the legs. Bending the hip more than 90 degrees increases the risk of the femoral head slipping out of the acetabulum, especially from a posterior approach, and crossing the legs or ankles compromises alignment, also raising the dislocation risk. The other options would either allow dangerous positions or ignore necessary restrictions, making dislocation more likely. In practice, use a raised chair or toilet seat, keep the hip in neutral alignment, avoid deep bending or twisting, and use assistive devices to reach objects without bending at the hip. Keep in mind specifics can vary with surgical approach, but the goal is consistent: minimize hip flexion beyond 90 degrees and avoid crossing legs to prevent dislocation.
