What experience have you had with partial or full knee replacement surgery? What was your recovery like? How has it impacted your tennis game. I am very confused. I have spoken to 4 surgeons. Two have recommended full knee replacements, two have recommended partial knee replacements. Of the two who recommend full replacement, one would take MRIs of my knee and send them off to whoever supplies replacements; the other uses less of a "custom knee". Of the two doctors who would do partial replacement, one uses a method called Maaco which uses an MRI for laser guiding of the surgeon; the other is laproscopic but not as customized. I am 66 year old 4.0 who likes to play daily. Any insights would be very much appreciated.
