Knee pain is a common problem that can affect people of all ages. It may result from injury, medical conditions, or everyday wear and tear. Because the knee is one of the most used joints in the body, pain in this area can interfere with walking, sitting, climbing stairs, and overall quality of life.

- Rheumatoid arthritis and other inflammatory conditions
- Sports injuries or overuse of the knee joint
- Obesity, which puts extra pressure on the knees
- Poor posture or improper movement patterns
