You got it. You have to lose weight. Too much load/weight on the joints, and your body can't handle it. Don't stay static while you're recovering from surgery (except for immediately after, of course). Upper body weight training is good. When your surgeon gives you the okay, start an aquatics program. Strenthens the muscles under reduced load. Swimming is good too (use a foam pillow to float the legs, while you use your upper body to thrust). Tons of fitness things you can do with a bum knee, until you are healthy enough to increase load on land.
Once you're back in tennis, PRACTICE running in all directions: forward, side shuffle, back sprint, and diagonally. That keeps all stability muscles in check
Thanks UCFS. Yeah, not going to rush back this time. Going to lose the weight and stick with the gym until I feel really fit and strong. Then will hit the courts again.
