Thank you Sueimn! I too have a hip replacement from a ski injury that Ive played soccer on for 13 years so far without a problem. The ankle joint though is mysterious. There just aren't a lot of them out there. I appreciate your cautionary advice, but am still bewildered. My surgeon said he is not allowed to recommend cutting sports on an ankle replacement, but many of his patients do play cutting sports like basketball and soccer. And he said if you wear it out it's not a big deal to just slide in another plastic donut between the the capped tibial plateau and the long bones. I do think though the danger of cutting sports might be the loosening of the implanted caps and that could be serious.
