About Osteoarthritis Knee Pain

How a knee with OA differs from a healthy knee
In a normal, healthy knee joint, there is a fluid that acts as both a cushion and a lubricant. In a knee with osteoarthritis, the features of this fluid are reduced, and the cartilage at the end of the bones wears down. Bone may be exposed, and bony protrusions called spurs may form. Joint space can be reduced and movement can be limited. The lining of the joint may become irritated, and you may feel pain in the knee.

How OA knee pain is treated
In general, OA knee pain can be treated nonsurgically, but in more severe cases, surgery may be required. Oral medications provide only temporary pain relief, up to 24 hours, while injectable treatments can provide OA knee pain relief that can last for weeks to months.
