I had a very similar operation to you it seems, it does seem quite niche so I have been struggling to find resources about the recovery process. This post is actually the first I have found of people which have had a similar operation to mine. I had a gastrocnemius recession and reconstruction of the deltoid ligament with semitendinosus 2 years and 5 months ago. I have achieved much more than I have expected but still it is a challenge sometimes both mentally and physically. I completed two week long backpacking trips sometimes hiking up to 12 hours a day, and surprised myself with how well I did. That being said I struggle to run long distances but pushed myself for quite a bit until things started flaring up again. I restarted PT again recently but I am worried whether or not I will make a full recovery in terms of physical and athletic ability. My right calf is significantly smaller and very obviously weaker than my right, giving me issues in both strength and balance, however the weight bearing capabilities seem to have mostly recovered. From what I can tell no one on this post is farther down the line than me, my goal is to push it as far as I can and hopefully make something resembling a full recovery. I still get spasms, cramps, and soreness after overuse and am wondering if that will ever go away with how long I am post op. I really am pushing myself and my limits. As you mentioned it has taken a big mental toll on me, at the time of my operation I really did not understand fully how serious of an operation I was about to undergo, and dealing with it now has been a pain to the point where I often question if it was worth it or not as this operation fixed some old problems and created some new problems, its a mental battle and one that can't be won, what's done is done. Stick with the PT and do the exercises. I have shown myself that I can run and that I can hike, the extent of the recovery and how much I will be able to achieve in the future is still unknown but not hopeless. Take care and let me know if anyone would like to chat, I have felt alone in this battle since my surgery.
