Xu T, Yang D, Liu K, et al. - Researchers conducted a randomized controlled study comparing standard supervised physiotherapy (SPT) vs a self-developed, home-based, enhanced knee flexion exercise program involving a low stool (KFEH) in patients who underwent total knee arthroplasty (TKA). Patients were randomly assigned to one of two groups: KFEH (n = 60) and SPT (n = 59). Outcomes revealed achievement of better ROM at early discharge among patients assigned to the self-developed home-based enhanced knee flexion exercise program. Further, non inferior measures of VAS, KSS, and WOMAC scores, and complication rates to SPT were recorded during the 12-month follow-up period. Furthermore, using a home-based program for TKA rehabilitation was verified as efficient and cost-effective. Via minimizing face to face contact, this home-based program might decrease the risk of coronavirus infection.
