Self-reported chair-rise ability relates to stair-climbing readiness of total knee arthroplasty patients: a pilot study.
Following total knee arthroplasty (TKA), physical therapists must evaluate patient readiness to safely begin stair-climbing. Physical therapists might find self-reported chair-rise ability useful in determining stair-climbing readiness of patients. We grouped 31 subjects who were at approximately 3.6 weeks post-TKA by chair-rise ability (group 1 = "Because of my knee, I can only rise from a chair if I use my hands and arms to assist," group 2 = "I have pain when rising from the seated position, but it does not affect my ability to rise from the seated position," and group 3 = "My knee does not affect my ability to rise from a chair"). Next, we determined time of stair-climbing ascent and descent, number of chair rises in 30 seconds, isokinetic quadriceps femoris and hamstring muscle group strength, and self-reported knee function survey scores. Groups 3 and 2 descended stairs more quickly than group 1; group 3 displayed greater involved and noninvolved knee extensor torque per body weight than group 1 or 2 and had superior self-reported knee function scores than group 1. Patient perception of chair-rise ability at approximately 3.6 weeks post-TKA is useful in helping physical therapists determine patient readiness to safely begin stair-climbing.
