Which of the following is recommended after a total hip arthroplasty?

After a total hip arthroplasty, maintaining the hip at no more than 90 degrees when sitting is crucial for preventing dislocation of the hip joint. During the initial recovery period, patients are at an increased risk of dislocating the newly implanted hip joint, especially if they bend at the hip excessively. By keeping the hip at or below 90 degrees, patients can avoid stressful positions that may compromise the integrity of the joint and ensure a safe healing process.

While using a recliner may be comfortable, it does not specifically address the degree of hip flexion necessary for safety after surgery. Placing a pillow under the knees at night can actually promote flexion beyond the recommended angle, increasing dislocation risk. Walking without assistance may also lead to complications if the patient lacks stability, especially initially post-surgery. Therefore, the emphasis on maintaining hip flexion below 90 degrees directly correlates to post-operative safety and prevention of injury.
