Tough break and just when you were playing even better golf.
Had my left knee reconstructed 20 some years ago after tearing the ACL playing baseball. I had to had 2 other scopes to take out torn cartilage within a 2 year period after the ACL reconstruction. I still have tendonitis from the patellar tendon graft that was used from the same knee to repair the ACL. But, it lasted 4 years of college baseball and has held up with what I do now.
What's your surgeon using to repair the ligament--cadaver ligament, tendon graft, synthetic, I've heard they can use pig ligament too? They should be able to do the surgery arthroscopically.
