Which of the following would be most appropriate when training a firefighter 10 weeks post-ACL reconstruction?

The most appropriate option for training a firefighter 10 weeks post-ACL reconstruction is squats up to 60 degrees of knee flexion. At this stage in rehabilitation, it is important to focus on rebuilding strength, mobility, and functional capacity without overwhelming the healing tissues.

Squats within this range allow for a controlled movement pattern that engages the quadriceps, hamstrings, and glutes while not placing excessive strain on the knee joint. This degree of flexion ensures that the knee is not subjected to high compressive forces that can occur with deeper squats, which may be inappropriate so soon after surgery.

Additionally, squatting is a compound movement that mimics many functional tasks that a firefighter might perform, making it beneficial for their specific demands. Using this exercise also encourages joint stability and proper tracking of the knee during movement, which is critical following an ACL injury.

The other options may not align with the rehabilitation goals or risk management for someone at this stage. Seated knee extensions focus on isolation of the quadriceps and may place undue strain on an already recovering knee. Low-intensity skipping drills would introduce dynamic movements that could risk instability or reinjury. Leg press exercises might allow for greater load but could also lead to improper alignment and unanticipated
