In reply to razmitaz: In 2007 after months of pain I had a total knee replacement,(TKR). After more months of carefully structured hard work, exercising, swimming and being careful I started climbing again by going to my local wall, Kendal, and doing easy low level traverses. This allows you to build up problems gradually and if you need to you just step off the wall, rest, and start again. I was climbing well and ski-ing within 6 months of the Op. Unfortunately I am now heading for another TKR but intend to follow the same procedure and hope to be climbing again as soon after the op as I can. Hope you also return to climbing soon. Good Luck.
