Yes, I do. Sorry this is long, but if I can help just 1 person, I'll be pleased.
Diagnosed when I was also only 40. I'm an ex dancer and athlete, used to walk a great deal and had a job mainly on my feet. Dr thought part wear and tear and part genetics. At one point I was in agony. I couldn't even lie in bed, absolutely still, without pain. I've never been depressed nor had dark thoughts, but I'd be crying in pain all the time, not sleeping and honestly thought having it amputation would be a better option. I was not offered a steroid injection and told I should hold off having a replacement because I was still young. I tried turmeric, gel rubs, heat pads, ice pads and all sorts.
The consultant said I shouldn't be in that much pain as the osteo was mild apparently. I'd read up about stem cell transplant, but he said the NHS don't have enough evidence to find it effective, but if I went to Harley St, someone there would take my money! As I was walking out the room, I showed him the boots knee brace I'd bought. It was purely in passing he mentioned a uni loader brace- which changed my life!
My arthritis is worse on the inner aspect of my knee. The uniloader uses straps to move your weight to the better side of the knee and opens up the grinding/painful side. I had 2 types over about 2 yrs, both provided on the NHS:
-Thusane brand. Soft, stretchy fabric with straps. It fitted under loose trousers so was discreet. I did find the elastic started to stretch and loose shape after about 6mths so was given another, but it soon did the same.
-Harder, exo skeleton type. A metal type brace. It did the same thing but due to the size, I had to wear it over trousers. The metal work also rubbed certain parts of my leg so I needed to use little foam pads to prevent that.
Being able to walk again was a game changer. I lost weight, could do physio, and work more hours. With physio and time I was able to ween myself off the brace altogether. That was 5yrs ago. I do the odd stretching now but not all the time. If I do a long walk, I feel it the next day, but don't have any of the pain I previously had and don't feel the need for a replacement anytime soon. I still can't squat or kneel easily though. I have no idea if it was psychosomatic, I did actually strengthen my muscles to support the knee or something else was going on? Happy to answer any questions you have x
