What is the target knee flexion range by the end of CPM treatment?

• A. 90-100 degrees
• B. 110-120 degrees
• C. 120-130 degrees
• D. 100-110 degrees

Answer: (B)

Continuous passive motion is used after knee surgery to gradually stretch the joint while protecting healing tissues. By the end of CPM therapy, a target of about 110 to 120 degrees of knee flexion is chosen because it provides enough bending for many daily activities—such as sitting comfortably, stepping and climbing stairs—without pushing healing structures too far too soon. If the end range were only around 90 to 100 degrees, functional tasks would be harder and stiffness risk would stay higher. Pushing toward 120 to 130 degrees too early can increase tissue stress during recovery. So, 110–120 degrees is a practical, functional end goal for most CPM protocols.
