Hi

I think anyone who is serious about playing football again after the injuries mentioned needs to focus on a comprehensive rehab programme that involves graduated strengthening as the knee improves and builds strength, leading to agility drills which mimic the actions undertaken during football (ie dribbling the ball, changing direction etc) and ultimately doing plyometrics to increase strength and power. This needs to be under the supervision of a physio so that the appropriate exercises are given at the appropriate stage of recovery.

Good luck
