Continuous passive motion following total knee replacement: a prospective randomized trial with follow-up to 1 year
We have carried out a prospect i ve r and omised , single blind clinical trial to investigate the effect of continuous passive motion on range of knee flexion , lack of extension , pain levels and analgesic use after total knee replacement surgery . 85 subjects were r and omly allocated to control or study group . All subjects followed the existing rehabilitation protocol , which permits immediate active range of motion exercises and mobilisation with the study group using continuous passive motion for 1 h , twice a day . Outcome measures employed were range of motion , pain assessed on a visual analogue scale and analgesic use according to the WHO ladder . Blinded evaluation was carried out preoperatively , at time of discharge from hospital , 6 weeks , 6 and 12 months postoperation . No significant difference was observed between groups at all time intervals for each outcome variable using Wilcoxon Rank sum tests . The results substantiate previous findings that short duration continuous passive motion following total knee arthroplasty does not influence outcome of range of motion or reported pain
