Table 3 Studies investigating the usefulness of continuous passive motion after total knee replacement
Ref.Type of studyOutcome
Maniar et al[35]Prospective randomized trial. To use or not to use continuous passive motion post TKRNo benefit from CPM use in immediate functional recovery post-TKR and postoperative ROM. The postoperative knee swelling persisted longer in the CPM group
He et al[34]Meta-analysis of randomized trials (Cochrane). CPM or not against VTENo evidence that CPM reduces VTE after TKR
Harvey et al[33]Meta-analysis of randomized trials (Cohrane). CPM use or notCPM increases passive knee flexion ROM by mean 2 degrees and active knee flexion ROM by mean 3 degrees. This effect is too small to clinically justify the use of CPM. Weak evidence that CPM reduces the need for manipulation under anesthesia
Alkire et al[32]Prospective randomized study. CPM use or not for computer-assisted TKANo statistically significant difference in flexion, edema or drainage, function, or pain between groups 3 mo post-surgery
Lensenn et al[31]Randomised controlled trial. Effectiveness of prolonged CPM use vs in hospital only use of CPMNo long term difference in ROM or any of the outcome assessments
Leach et al[29]Prospective randomized trial investigating the effect of CPM on range of knee flexion, lack of extension, pain levels and analgesic use after TKRNo differences among studied groups
Brosseau et al[28]Meta-analysis of studies examining the effectiveness of CPMSignificant improvement in active knee flexion and analgesic use 2 wk postoperatively with the use of CPM and PT compared with PT alone
