Methods From June 2008 to June 2009, 86 patients were treated due to closed tibial plateau fractures without combined injuries. The patients were treated with (27 patients, CPM group) and without (59 patients, control group) CPM. The wound healing rates, range of motion and the knee function were compared between the two groups. Results There was no significant difference between the two groups in wound healing rates (P=0.566). Two and six weeks after the operation, there were significant differences between the two groups in flexion degree (Plt;0.001); three and 12 months after the operation, there were no significant differences between the two groups (P=0.219, P=0.512). At the 2nd and 6th week, 3rd and 12th month postoperatively, there were no significant differences between the groups in extension degree. Twelve months after the operation, there were no significant differences between the groups in functional recovery of the knee. Conclusion CPM in the post-operative treatment of tibial plateau fractures is effective increasing knee flexion in the early stage, but is not effective increasing range of motion or knee function in a long term.
