Hey,
Thanks for taking the time to reply. Since I last posted I have seen an orthopaedic specialist who sent me for an X-ray that showed no bone damage. I'm now on waiting list for a scan which could be a few months.
I mentioned my history of knee injuries to the specialist, he said it was very unlikely that I'd ruptured it completely. After examination he reckoned my knee was stable enough and didn't think there was any ACL damage but said the scan would give him a better idea. Didn't offer much advice, so I'm still in the dark!
The knee is still giving me a lot of bother after 3 months, too painful to flex and extend fully. I've been in the gym using the exercise bikes and doing some weights too as theres been a lot of muscle wastage about the knee. For someone that's usually very active, the past 3 months have been awful, just so annoying!!
