10 Causes of Knee Pain
Reviewed: Dr. Gromatzky
Cause #3: Osteoarthritis
Osteoarthritis is a degenerative condition. When it occurs in the knee, it is referred to as degenerative arthritis of the knee or simply, wear-and-tear arthritis. It is a condition that occurs when the cartilage inside the joints begins to wear away.
This cartilage prevents the bones in the joints from rubbing together, but when it wears away, there is nothing to stop them. This can create pain, inflammation, and swelling. As a degenerative condition, osteoarthritis tends to get worse if it’s not managed properly.
