Knee Surgery

Let me start off by saying that I am new to blogging and that this is my first blog. I recently had arthroscopic knee surgery, four weeks ago, and was looking for someone online to commiserate with. I just wanted to know if anyone else out there was going through the same things. Since I didn't find anyone, I thought I would just start my own post and see if anyone else jumps in. And anyway, I like to write and this seemed like a perfect place.
Ever since I was little, I've been playing some kind of sport. The first knee injury I can remember was when I was about 4 years old and I was adamant about learning how to ride a bicycle. So I took my two wheeler (without the training wheels)and headed out to the gravel driveway to teach myself. Needless to say, I had so many cuts and scrapes on my knees that the mercurichrome (remember that!) completely covered my knee caps. But I learned how to ride.
After that, I remember falling from trees and neighbors railings trying to keep up with the dares from neighborhood kids. In the summer we would play kickball and stickball in the streets. You really couldn't slide into bases, but you did alot of crashing into cars. And then, the ultimate game............. dodge ball. Now I'm not blaming my degenerating knees on dodgeball, but you have to admit, it is a rough sport.
The last twenty years though, I've been playing alot of tennis. There were a few years when my children were small, that I played six days a week. I was on one women's league, subbed on another, had my weekly clinic, team practice and a social game or two. I did this for years. in Florida we play all year long too! That combined with the gym (aerobics, spinning) and jogging with the dog, it's no wonder that at 51 I needed arthroscopic surgery to repair a medial meniscus tear. While in there looking around, what the surgeon thought was a nick in my articular cartilage on the MRI was actually arthritis because there was no articular cartilage left.
Needless to say, the advice after surgery was no more tennis. As I left his office crying my eyes out and feeling very sorry for myself, I thought that this can't be the end. I've heard of plenty of people playing with cartilage problems. So you see, that is the reason for this post. "Hey all you people out there with no cartilage, tell me how you are. " Do you play tennis? I'd like to find out how others are making it after surgery.
I am going to PT and walking in the pool. Today I'm trying the eliptical at the gym. Like I said, it's been four weeks. Can I start jogging now?
