To assess the effects of preoperative balance training on the early postoperative balance and functional outcomes after total knee replacement surgery and to test whether an outpatient intervention may be as effective as a domiciliary intervention.
This is a three-arm randomized controlled trial.
University hospital.
Eighty-six individuals were recruited. Seventy-seven were analysed, aged 72.1 (SD 7.6) years, of which 68% were women.
Overall state of balance, as measured with the Berg Balance Scale, and patient-perceived functionality, as measured with the Knee Injury and Osteoarthritis Outcome Score Function in Activities in Daily Living (KOOS-ADL) questionnaire, were the primary outcomes. Secondary assessments targeted knee function, balance and mobility, quality of life, and self-reported outcomes. The primary end-point was six weeks after surgery.
The hospital group implemented a four-week preoperative outpatient balance-oriented intervention. The home group implemented similar training, but this was domiciliary. The control group was instructed to keep performing their normal activities.
Home and hospital groups presented a moderate effect against the control group (
Preoperative balance training, conducted either as domiciliary or as an outpatient, is an effective approach to enhance early postoperative balance outcome but not the perceived functionality of individuals undergoing total knee replacement.
