My experience - It took me about 3 months to really clear this thing with 4 different physical therapists. My condition started 4 months ago and I was really frustrated about the lack of progress in the first two months after doing tons of stretches and seeing PTs. What really helped: 1. Rest - took a 2 week break from tennis during month 2. And limiting myself to 1 tennis games/week in month 3 really helped to calm my knees 2. Finding the right PT - the last PT diagnosed my problems more quickly and got me to stretch better and did more muscle stimulating routines and icing. 3. Doing the right stretches. The PT taught me some. But the best book I could find is this one by Susanna McGee. It's very comprehensive. http://www.amazon.com/Tennis-Fitness-Love-Approach-Injury-free/dp/0982949960 4. Don't sit too long. I try to stand/work instead of sit/work. Sitting is really bad for the gluteus muscles. 5. I bought a bunch of knee braces (Proband KneedIT, double hingers, etc. etc.). The one thing that helped was the Ace brand neoprene. But I only started wearing it from month 3. It seems to help to keep my knee warmed up for tennis. I didn't wear it when my knee was still crunchy cause I thought it may make it worse.
