Good luck with your 2nd opinion, good move. Hot Rod had lp surgery on one of his knees and like Vivian said, the post op is the hard part. We had to keep Hot Rod still for 6 weeks and about the 4th week it was very long.
But all worth it. He will still pick his leg up but he's tight as can be and the surgeon doesn't believe that he will have arithis from this in his knee.
Please keep us update on your appt. Best of wishes. Hugs.
