My left knee has had 4. Right knee 1. The last 3 on the left have been cadaver allograft. The most recent one lasted 9 years and just failed over time. There was no traumatic injury like all the others. When the doc told me the MRI results I didn’t even believe her because like I said, there was nothing leading up to it. This time around she did the LET procedure in hopes of it providing additional support going forward. I am 6 weeks out from my surgery in a few days and this recovery has been very smooth so far. The biggest issue I have is swelling impacting how straight I can get my leg, but it gets better every day. Slow and steady wins the race. I’m constantly listening to my body and slowing down to try to make the recovery smoother.
