brian,
You're getting physical agented (is that a word) to death...e-stim, phonophoresis with cortisone (that's useless by the way)?? What ever happened to plain old ice, ice, baby?
What the heck are they stretching

and how is that supposed to help and ACL Sprain (strains are muscles and tendons) and meniscus tear.
If there is concern over damage to the ACL supported squats on the wall are not a good choice. The hamstrings don't fire effectively and the quads will create a drawer effect which tenses the ACL.
Step-ups at a pain-free level, posterior chain exercises (glutes and hamstrings), unilateral bridging, sled drags/pushes, and squat variations to comfortable depths are good choices depending on symptoms.
If you have any effusion in the joint, your VMO may be inhibited. Does the joint feel really tight when you bend all the way? Most leg press variations in clinic will have a high foot placement on the footboard which emphasizes posterior chain. Lowering your foot placement may load the knee quite a bit. I personally don't use a leg press for any rehab patient.
Take everything I've said with a grain of salt (except for the phono thing...useless

) as I have not examined you. Your status, pain level, and actual diagnosis will drive your rehab.
When do you follow-up with the doc? Have you improved?
Bill
