Steve,
Typically neither of those structures in the knee get better without surgery. Time to find a great sports med surgeon. The medial meniscus typically is just resected and made even, it is rarely repairable. The ACL is replaced with a cadaver graft (dead guys tendon). Going to be a lot of physical therapy post op but folks do great with these surgeries. Good luck!
Go to dr first in clear lake guy is world class and probably best around. He is a little blunt but incredible surgical doctor.
