In between filming Yes, Madam! (1985) and The Millionaires' Express (1986), Rothrock ripped the anterior cruciate ligament in her right knee. Turning down the option of reconstructive surgery because of her tight filming schedule, she amazed doctors by continuing to work without adverse effects. While the injury would normally have caused recurring dislocation of the kneecap, a study on her leg revealed that Rothrock's quadriceps and hamstrings were so strong that they held her kneecap in place even without the aid of the ligament. As of June 2012, Rothrock still had not undergone reconstructive surgery.
