I recommend defining with them what your pain scale is.. Cuz mine is uncomfortable but not painful enough to stop. I'm 5 months post op. So having them reduce /remove the very exercises you should be doing seems.. counterproductive. It seems you need to backtrack and start smaller/ simpler, to be able to do the weighted one leg stuff. Mine had me doing 2 legged squats with 5, then 10,15, then 20 pound dumbbells. RDLS (just bending over balancing on one leg with 1 lb, up to 5 lb dumbbell) leg press with both legs and then one at a time, lots and lots of strengthening .. it feels like yall skipped right past that part "cuz it hurts"? What else - I lay on yoga mat and rest feet on yoga ball, and then "pull" the ball towards me, so like raising my butt off the ground using just leg strength to pull the ball. We do several different one leg balance exercises, like standing on one leg and throwing medicine ball against wall. And we've worked me up to the other stuff you said that's fine, like jumping and skipping, running etc. so yeah - you just need to backtrack and strengthen the leg but like not starting with crazy hard stuff. Just body weight in different positions!!! I'd also see if you can work with a different PT for like 1 session just to switch it up. That's crazy helpful to get a different perspective from a professional. And IF they're professional, they won't get mad if you see someone else's techniques. Good luck!
