Prehabilitation and quality of life three months after total knee arthroplasty: a pilot study

Knee osteoarthritis (OA), which affects over 27 million Americans, decreases the individual's quality of life through decreasing mobility, deconditioning, reducing functional ability, and increasing knee pain. The present aim was to assess whether such patients engaging in exercise prior to surgery ("prehabilitation"; preoperative exercise intervention) rate higher quality of life 3 mo. after their surgery compared with ratings by patients who did not engage in prehabilitation. Standard populations consist of OA patients that do not participate in any preoperative exercise programs, such as a prehabilitation exercise intervention. 18 knee osteoarthritis patients were randomly assigned to a control or a prehabilitation group. The latter group participated in an exercise intervention three times per week, once at home and twice at the physical therapy lab, for 8 wk. prior to their surgery. The control group participated in their usual preoperative care prescribed by the physician for all patients. Eight health-related quality of life domains were assessed at 3 mo. post surgery. These preliminary findings suggest efficacy of prehabilitation in facilitating quality of life of total knee arthroplasty (TKA) patients 3 mo. after surgery.
