Oh no Betsi, I'm so sorry
I remember doing ACL repairs but not MCL repairs. Their not that bad and if it helps in the long run why not. The only thing that pisses me off is that those darn orthopedics hate stitching and use staples even when it's laparoscopy procedure. You know they don't have to put you all under either.
Please be careful and do as your doctor order. XOXO
