Oh gentleshores, I do sympathise with you in your predicament. I'm not medically trained but do try and keep up with medical issues. I have heard it said that medical training and practice these days tends to encourage a piecemeal approach to the human body instead of a systemic one. It sounds to me as if that is what has happened to you. How about consulting an Osteopath? Their training and knowledge of human anatomy is impressive and doctors have been known to admit that the osteopaths are more thoroughly trained than they are themselves as GPs! I myself have greatly benefitted from osteopathy on my back and knees in years past. Obviously this is not available on the NHS but half a dozen or so sessions could well see you right or at least very much improved. Wishing you well in the near future!
The thing I find frustrating is, the only real solution for knee cartilage tears, that impact your ability to walk or do steps - is a repair. There's virtually no blood supply in cartilage so it doesn't heal on its own. It needs someone to look at the MRI scans and determine what type of tear it is and where as some are repairable and some aren't, If they're not repairable it means removing some of the cartilage (but not all of it - they don't do that these days). The argument is that surgery to repair or remove cartilage, causes or worsens arthritis. So they don't want to do the surgery on anyone (seemingly) over 60!
But I researched this myself and it's wrong. It is only a risk to cause arthritis if the arthroscopy is done for arthritis rather than cartilage, - ie if you already have arthritis. My scans and x rays have consistently said "no arthritis". Although the physio now says my latest x ray does show some arthritis. So it looks like they won't even consider me for surgery, Both physios "wrote me off" as "it's degenerative". I keep telling them it was caused by injury originally. But at least having someone look at the scans would be a start to decide whether they're repairable or not.
The newer option is stem cell injections, which are a much lesser surgery and regrow/repair the cartilage using your own stem cells. However, I need to be better "conditioned" for any procedure really. I am still doing some of the physio exercises but I can't do the standing ones.
So while they might say there's a medical reason for it being about my age, I think it's too quickly and easily dismissed and not looking at individual circumstances.
It's a real long shot to get the stem cell treatment, even if I can get a referral from orthopaedics now. One thing that was explained was you have a lot less stem cells to harvest when you get older.
