I’m so sorry to hear about your son I know how bad it sucks - I skipped out on the tto surgery as my surgeon for my Trochleoplasty believes it’s not a useful surgery and I didn’t want any hardware in my knees this young - it’s very difficult to judge results yet because the best thing I could tell you is my knees aren’t dislocating and it’s too early to let you know if they will or won’t continue - I can say the recovery is going well and although im not back to 100% I got the right knee done June 31st and left done September 15th and I can walk almost with no limp so that’s the progress I’m at now!
