Continuous Passive Motion is commonly used after which scenario?

• A. Postoperative knee procedures
• B. Acute ankle sprain
• C. Chronic back pain
• D. Acute concussion

Answer: (A)

Continuous Passive Motion devices move a joint through a controlled range of motion without the patient actively contracting muscles. They’re used early in the healing process to keep the joint flexible, reduce scar tissue, and promote circulation, while protecting healing tissues. This approach is most beneficial after knee surgery, where stiffness is a common concern and gradual, controlled movement helps restore motion after procedures like knee arthroplasty or meniscal/ligament repairs. Therefore, continuous passive motion is commonly used after postoperative knee procedures. It isn’t typically used for an acute ankle sprain, chronic back pain, or an acute concussion, where other rehab strategies are more appropriate.
