What is critical for safe driving after knee replacement surgery?

Flexibility of the knee is crucial for safe driving after knee replacement surgery because it directly impacts the driver's ability to operate the vehicle effectively. Adequate knee flexibility ensures that the driver can comfortably and safely perform necessary movements, such as pressing the brake and accelerator pedals or repositioning their foot quickly in response to sudden driving situations.

Post-surgery, individuals typically undergo a rehabilitation process focused on improving not only strength but also the range of motion in the affected knee. Without sufficient flexibility, a driver may risk reduced reaction times or difficulty in maintaining control of the vehicle, which can compromise safety on the road.

While factors such as arm strength, weight of the driver, and condition of the vehicle also play roles in overall driving safety, they are not as directly related to the specific impacts of knee function after surgery. Proper flexibility in the knee is essential for proper pedal operation and overall driving performance.
