Classical signs and symptoms of osteoarthritis

Classical symptoms include pain at rest, reduced exercise tolerance, joint swelling.

Classical imaging signs include joint line narrowing, bone spurs, bone cysts, areas of increased bone denisty (sclerosis).

Usually knee osteoarthritis begins in one part of the knee (what we call a 'compartment'), and only later does it progress to involve the other compartments. This gives the patient the option to try to arrest progression by suitable intervention.
