Reporting on my own case of knee problem:
Ca 2014, after a serious fall, I developed knee pain (the walk-in treatment centre in Nottingham had only treated my heavily bleeding thumb). Eventually a young doc after an x-ray (in Bonn) confirmed what one of the same in the UK had told me already: knee replacement was the only way. Instead, I did my own research, used acupuncture and acupressure, bandages and some natural remedies, I am now 85% pain-free and have 75% mobility in that knee. Pretty good outcome for one of those replacements I gather, without the cost. 😏 You may want to say that was an untypical case. However professionally, as a social worker, in England, I have found that similar happens very frequently. I do all I can to empower would-be patients to do their own responsible research.
