Hello I had an ACL reconstruction 17 years ago and never regained full range of motion. I had further surgery after a few months - supposedly to release what was causing problems - and that may have helped a bit but I've been left with a knee that cant fully bend or straighten (other than under pressure), and gets inflamed and sore more often than one would like. Haven't done anything high impact since the surgery, I kept up distance walking for quite a while but it gets harder and more painful to recover so generally avoiding too much walking now. Reformer pilates and aqua aerobics are my go-to activities - eventually couldn't manage standing poses in yoga. Over time I've strengthened all the supporting muscles and with passive stretching and regular but not daily NSAIDS I'm not incapacitated. I just limp at times. I'm really fed up with never finding anyone who could tell me why my knee wasn't right - MRI looked OK according to the sports physician. So maybe this arthrofibrosis and if it is, does that mean there could be a diagnosis based on blood chemicals? And possibly a quite different form of treatment. Who can I talk to in Sydney? If I self-fund a cytokine panel, I'll want someone to interpret it. Any advice would be much appreciated. Thanks Debbie K
