We studied the relationship between how patients believed they could rise from a chair following total knee replacement (TKR) surgery and stair-climbing readiness. Group 1 believed they could only rise from a chair using their hands and   arms. Group 2 believed that their pain did not affect their ability to rise from a chair. Group 3 believed that their knee did not affect their ability to rise from a chair. We measured stair-climbing time, chair-rise repetitions, knee muscle strength, and physical function. Group 3 descended stairs quicker, performed more chair-rise repetitions, and had better knee survey scores than group 1. Group 3 had greater involved and noninvolved knee muscle strength than groups 1 or 2. Patients' beliefs about chair-rise capability approximately 3.6 weeks after TKR surgery helped physical therapists determine stair-climbing readiness.
