OA is primarily caused by wear and tear on the knee joint over time, leading to the breakdown of cartilage, the cushioning tissue that covers the ends of bones in joints.
- - Age: OA becomes more common with age.
- - Obesity: Excess weight increases stress on the knee joints.
- - Joint Injury: Previous knee injuries or surgeries can predispose individuals to OA.
- - Genetics: Family history of OA can increase susceptibility.
- - Gender: Women are more likely to develop knee OA compared to men.
- Pain: Gradual onset of pain that worsens with activity and improves with rest.
- Stiffness: Morning stiffness or stiffness after periods of inactivity.
