Abstract: Objective To observe the effect of early rehabilitation training combined with continuous passive motion (CPM) on knee joint function after total knee arthroplasty (TKA).Methods23 patients (28 knees) post TKA were randomly divided into the treatment group (15 knees) and control group (13 knees). The patients of the treatment group were treated with early rehabilitation training combined with CPM, and those of the control group were treated with CPM only.ResultsThe scores of knee grade and function grade of the treatment group were not different from those of the control group before treatment ( P>0.05), but two weeks later, there was a significnat difference between two groups ( P<0.01).ConclusionThe early rehabilitation training combined with CPM can improve recovery of function of knee joint after TKA.
