Non-inflammatory knee pain is usually caused by injuries to the cartilage surrounding the knee. Many forms of minor knee pain can be helped by simple self-care steps. Ice packs and cold showers can decrease inflammation, which will make healing easier. Knee braces and physical therapy can also help alleviate minor knee pain caused by various mechanical problems. In some instances, though, your knee might need more invasive surgery.
If you experience knee pain that interferes with normal activity, you should consult a physician. He or she will first evaluate the cause of the pain, which may be due to a physical therapy or knee brace that does not adequately support the muscles supporting your joint. Your doctor may recommend physical therapy to strengthen your muscles and restore range of motion if needed. Knee surgery may be necessary in some instances, so be sure to discuss all of your options with your doctor.
