What are risk factors for knee pain?
Biomechanics: The knee joint is a complicated in its operation and is used frequently throughout the day. Any change in the movement of the joint (leg-length difference, change in walking style due to back problems) can cause subtle changes and cause pain and injuries.
Excess weight: The stress on the knee joint is increased with excess weight. Obesity also increases the risk of osteoarthritis as the cartilage breaks down more rapidly.
Overuse during repetitive motions as are found during certain exercises (jogging, skiing) or work conditions (long periods of kneeling) can cause breakdown of cartilage and lead to pain.
When should people with knee pain call a health-care professional?
Any pain that does not respond to rest or disappears within a few days should be evaluated by a doctor. In addition, the following are symptoms and signs in the knee that a doctor should evaluate:
- Swelling
- Inability to bend
- Deformity
- Unable to walk or discomfort while walking
- Or a qualified therapist
