Which item is NOT listed as affecting prognosis after ACL reconstruction?

• A. Insurance status
• B. Age
• C. Activity level
• D. Rehab compliance

Answer: (A)

Prognosis after ACL reconstruction is shaped by factors tied to the knee’s healing and the rehabilitation process. Age influences healing capacity and how quickly strength and function can be restored. Activity level sets the demands placed on the graft and the risk profile for return to sport, which in turn affects functional outcomes and re-injury risk. Rehab compliance is essential because following the prescribed program ensures proper restoration of range of motion, strength, and neuromuscular control, with safe progression back to activity; poor adherence can lead to stiffness, weakness, and higher chances of reinjury. Insurance status, while it can impact access to care and resources, does not directly predict how well the knee will recover after reconstruction, so it is not considered a prognosis-influencing factor in this context.
