Question - ACL Rehab Exercises

by Carly
(Pennsylvania)

I had acl reconstruction on May 2, 2008 with a hamstring graft.
I haven't had much pain only sometimes behind my knee after exercising. I recently had to stop my physical therapy and I was wondering if anyone had some advice on what exercises I should do besides squats, lifting weights, lunges, jumping rope, box jumping, step ups, riding an exercise bike and running.

I really what to get back to playing volleyball because it's my senior year. I can pass and serve in volleyball and I'm gradually starting to hit again but, I'm afraid my leg will give out. My doctor also told me I don't need a brace.
If anyone has more exercises for me to do I would really appreciate it.

Thanks
