Destroyedbothtendons, I feel your pain. I am a double Patellar Tendon Rupturee (if that is a word, which I will trademark). I know it is a different situation/tendon, but there are a few of us out here with a double. I was working in my garden, which is on a slight slope and slipped in the mud and pretty much landed on my back with my heals hitting by butt. I felt the pain in my right knee and thought I could stand. How wrong I was. After attempting to get up three times, falling each time and doing a number on the right knee, I was able to crawl out of the garden to a retaining wall, where I was able to stand using a rake as a crutch and make it to my basement. After getting myself cleaned up and ready to go to the hospital, I stood up, and wham, there went the left knee. Needless to say, I knew I was screwed. Had no idea what a patellar tendon was until after the ER physician told me I needed them to stand and walk, both of which I would not be doing for awhile. I had surgery two day later and then had two weeks of intense rehab in a Specialty Rehab Hospital in St. Louis. After making it home, I was off work for another 6 weeks until I was able to get that first 30 degree bend in the braces. And one brace would be bad enough, but those of us with a double know the pain of two. 17 months later and still have some issues with my knees, but I manage to get better every few weeks.
I am not sure of a second surgery, except for the wire snipping. But I have some creaking and popping issues and the occasional pain and probably some arthritis, especially with the cold and rainy weather. If the OS says he can do it with out causing more issues and it will clean up the scar tissue, I say go for it. Hope it goes well.
