Hi Darshin
As Jenni says initially aspirations can last a while but unfortunately the synovial fluid will build up again over time. Sometimes it can be controlled by the RA meds generally so fingers crossed this will be the case for you. My knees always produce loads of the yucky stuff but it's better out than in and such a relief too to have it removed!
I had a synovectomy/debridement plus cartilage repair last year. Rather hoped it would keep the knee ticking over a while longer but it doesn't seem to be happening! Off to orthopaedics on Friday to see about two bad knees, an ankle that isn't functioning as it should, several subluxated metacarpophalangeal joints and severe ulnar drift of right hand as a result! Such fun ... I just love the hospital
Heyho on we go, no choice best just get on with it!
