Which exercise is most appropriate shortly after knee surgery to begin improving range of motion?

• A. Heavy squats
• B. Leg press
• C. Passive knee extension
• D. Full leg lift

Answer: (C)

Passive knee extension is the most appropriate exercise shortly after knee surgery for improving range of motion. This exercise allows for gentle stretching of the knee joint without placing excessive stress on the healing tissues. Passive movements facilitate the loosening of the joint and surrounding soft tissues, helping to restore flexibility without requiring the patient to actively engage their muscles, which may still be weak or compromised post-surgery.

This approach is essential in the early stages of recovery when the primary focus is on regaining range of motion while minimizing the risk of pain or further injury. As the patient progresses, they can gradually transition to more active or resistance-based exercises, but in the immediate phase following surgery, passive knee extension provides the safest and most effective means of promoting motion recovery.
