I am a 33 years old male who has experienced left knee pain since the age of 17 (no trauma). I had an x-ray at that time but it was all ok. It was not too problematic but in the last 2 years has become very problematic. It is painful to squat and then stand again and painful after running (not an excessive runner or sports person). I had an MRI which shows: minimal joint effusion, complete loss of joint space, marginal osteophytes and subchondral bone marrow oedema and cystic change of the proximal tibiofibular joint. It also showed thinning of the articular catilage at the patellar apex, focal thinning/fissuring of the articular catilage at the inferior aspect of the trochlear groove and lateral margin of the trochlea. Everything else was normal (summary: severe proximal tibiofibular osteoarthritis and mild patellofemoral arthritis). I did have juvenile arthritis as a 2 year old but subsequently recovered after 1 year.

Would the history of the juvenile arthritis cause osteoarthritis later on in life as I still feel quite young to be having idiopathic osteoarthritis without trauma or excessive use?
