Within 3 minutes of the bell's having rung today, I was getting into my car--had to rush to my ortho appointment to see how my recovery is progressing. Made it to the office with 2 minutes to spare!
The doctor is pleased with the improvement in strength and flexibility in my quad muscles and knee, saying the muscle mass looks good. She recommends I lay off running on the treadmill for another couple months until I get more strength in the leg, and since I don't enjoy her suggestion of riding the bikes at the gym, she suggested swimming (but the gym pool is cold!). I'll probably stick with my leg extensions and leg presses :-)
The best news, though, is that progress is sufficient such that she didn't schedule a next appointment, moving me instead to an "as needed" basis. I'm a week-and-a-half short of six months into this.
