I did have that surgery in my knee about 5 years ago, due to a torn meniscus, also using a sports medicine doctor. He cut out the ripped part and so far its been great. And no, he didn’t recommend exercises or rehab.
My wife had the arthroscopic surgery on both knees about 15 years ago and it worked out really well for her. No subsequent issues. She plays a lot of pickleball now, too.
