Try to hang in there and continue your current recovery before thinking of another operative procedure. If you feel scar tissue now, another surgery could possibly increase that. I'm facing meniscal tear surgery on May 13th with diagnostic scope to see how badly my kneecap cartilage is worn out (tilted and maltracking patella), and then will have to make the decision to live with the pain for a few more years or to ahead with a lateral release and TTT. I know that it's going to be a hard decision and that recovery will be long and not very fun, but it's part of my life and I'll have to deal with it.
I guess what I'm trying to say is that right now, you should put all of your energy and concentration on healing and getting your knee as strong as you can. The more you think "what if..." and stress out, the slower your knee will heal. It's tough, but it's a choice that you CAN make for yourself... you can spend time stressing and questioning yourself, or you can make a positive decision to put all of your energy and thought into healing and getting better. You can't change the fact that you've been through the lateral release, but you CAN make a conscious choice to focus on healing and strengthening from this point on and to make the best of it that you possibly can.
I'm sure once I have my surgery I'll be on this forum a lot more, and I'm sure I'll have "down" days as well. Though I haven't participated in the forum much to this point, I think this forum is going to be my sanity when I'm in recovery
Hang in there, and please keep us posted on how you're doing. Be strong!!!!
