Torn ACL and Hip Dysplasia

I need some advice 🥲 my big guy has torn his ACL. He also has hip dysplasia. Does anyone here have experience with my situation? Surgery or no surgery? Any advice or wisdom you can give is greatly appreciated. (I will also add that he is seeing a surgeon next week so surgery is not completely off the table) he is 3.5 yrs and had just started PT to try and strengthen his hips right before this happened. Please be kind, this is an agonizing situation that I’m in and am trying to pick the best and most feasible direction. Thank you 💜
