Gigi, everything I'm reading online says that the total knee replacement involves removing the meniscus and the cranial and caudal cruciate ligaments. From this source:
http://surgery.anzcvs.org.au/surgery...re%20Liska.pdf
"TKR is a menisci plus cranial and caudal cruciate sacrificing procedure so removal of a potential cause of postoperative complications (menisci injury) and an apparent inflammatory mediator (CCL) are eradicated." (This sentence starts at the bottom of page 2 and continues on to page 3).
I would get some clarification on why it's being "repaired" if I were you.
