Common symptoms include joint pain, stiffness, limited movement or reduced stability of the joint; it can resolve spontaneously or recur. The most common symptoms are pain in the affected joint, aggravated by activity, relieved by rest, and stiffness after a long period of inactivity, etc. The symptoms are not severe at the beginning, but gradually become painful during activity and after fatigue, and due to the involvement of the subchondral bone, patients may also feel dull pain and stiffness of inflexible joints at rest. If the patient has been in a fixed position for a long time, the pain can be felt at the beginning of the activity, but after a little activity, the pain is reduced. When a large piece of cartilage is lost and becomes free in the joint, the patient may experience sudden interlocking of the joint (the feeling that the joint is stuck), subcutaneous nodules in the finger joints, and swelling of the joint. However, there are some patients who only find osteophytes (bone spurs) on x-rays and do not have any symptoms themselves, which is medically referred to as radiological osteoarthritis or asymptomatic osteoarthritis.
