there's been some uncertainty about whether or not my knees have sustained permanent damage ('secondary' osteoarthritis & possibly other types of damage I don't understand yet). Saw my Rheumy today and he was adamant that such damage has occurred.
I've had 3 sets of x-rays this year: end of February, early June, end of August. Knees were okay in February but damaged by June 11th so if the Rheumy is right it took two and a half months for loss of cartilage, significantly reduced joint spaces & lipping to occur and by August it was worse still with some sort of hole beginning to form(!)
Unfortunately my time was nearly up (consultation-wise, not life!) by the time we got around to this issue so I'm left feeling very confused. My Rheumy's explanation for the speed of damage was that my quads had 'collapsed' because, presumably, of immobility caused by my PsA. But I was very active indeed up until this year & continued to walk & exercise as much as I could once I got ill except for about 2 weeks in April when I was almost completely immobilised by a nasty flare or something. In fact I had worried that the strenuous Yoga class I kept going to till about mid-March might have been partly to blame for the damage.
Has anyone else experienced something similar? Especially with knees, due to wasted & therefore unsupportive quadricep muscles?
