The posterolateral approach is associated with the highest risk of postoperative hip dislocation if the hip flexes beyond 80° to 90° during the early postoperative weeks. This is because the posterior capsule and hip abductors are disrupted during surgery, making the posterior hip joint less stable. The anterolateral approach has a lower risk of dislocation because it preserves the posterior capsule and hip abductors. The lateral approach also has a lower risk of dislocation, as it does not disrupt the posterior capsule. Therefore, options A and B are incorrect, and option D is a false statement.
