Continuous passive motion (CPM) after total knee arthroplasty speeds up knee motion recovery and reduces the risk of deep vein thrombosis. This study compared CPM patients to a control group, finding significant benefits for CPM use.

Area of Science:

  • Orthopedic Surgery
  • Rehabilitation Medicine
  • Vascular Surgery

Background:

  • Total knee arthroplasty (TKA) is a common procedure for end-stage knee arthritis.
  • Postoperative rehabilitation is crucial for optimal patient outcomes.
  • Deep vein thrombosis (DVT) is a significant complication following TKA.

Purpose of the Study:

  • To evaluate the efficacy of continuous passive motion (CPM) in accelerating knee flexion recovery after primary TKA.
  • To assess the impact of CPM on the incidence of DVT in patients undergoing TKA.

Main Methods:

  • Prospective study of 62 patients undergoing primary TKA.
  • 42 patients received postoperative CPM, while 20 served as controls.
  • All patients underwent postoperative venography to detect DVT.

Main Results:

  • CPM group achieved 90 degrees of knee flexion significantly faster (9.1 days) than controls (13.8 days).
  • No significant difference in flexion or extension was observed at hospital discharge between groups.
  • Incidence of DVT was lower in the CPM group (45%) compared to the control group (75%).

Conclusions:

  • Continuous passive motion (CPM) therapy enhances early range of motion recovery post-TKA.
  • CPM may offer a protective effect against the development of deep vein thrombosis after knee arthroplasty.
