Dr. Lemak did both of mine at Grandview. Rehab isn’t that bad if you have a good physical therapist. The quicker you get your hamstrings stretched back out the better. Both of mine still hurt, but not as bad as before. Arthritis eat mine up and as the doc said, he replaced the damaged joint, but the arthritis never goes away. So you’ll still deal with some pain and inflammation. It’s different for everyone though. Seems like it’s tougher to recover from the younger you are.
