Which of the following statements regarding the use of continuous passive motion (CPM) devices following total knee arthroplasty is true?
The use of CPM decreases the incidence of knee flexion contracture at 6 months following surgery.
The use of CPM has been associated with a decreased incidence of secondary surgery for knee manipulation.
The use of CPM has not demonstrated any difference in clinical outcomes at one year following surgery.
The use of CPM has been associated with increasing analgesic pain requirements in the first 3 days following surgery.
The use of CPM decreases knee flexion at one year following surgery.
