Thanks for the feedback and advice. The knee was replaced with a prosthetic, pretty amazing really, when you think about what they do.
You are right Mark , the physio is painfull, mainly exercise bike so far, and some squats, but early days yet and haven't sailed for nearly a year already. Sailing is flatwater am 64 yrs old but pretty fit, so no point in wrecking a $ 15000 knee before its use by date! (That is the cost if you don,t have private cover and won't, or can't wait at least 12 months for the public system......
