Knee pain is a common complaint that affects people of all ages. Knee pain may be the result of an injury, such as a ruptured ligament or torn cartilage. Medical conditions — including arthritis, gout and infections — also can cause knee pain.
Many types of minor knee pain respond well to self-care measures. Physical therapy and knee braces also can help relieve pain. In some cases, however, your knee may require surgical repair.
Knee pain can be caused by injuries, mechanical problems, types of arthritis and other problems.
The location and severity of knee pain may vary, depending on the cause of the problem. Signs and symptoms that sometimes accompany knee pain include:
1- Swelling and stiffness
2- Redness and warmth to the touch
3- Weakness or instability
4- Popping or crunching noises
5- Inability to fully straighten the knee
Medications
Your doctor may prescribe medications to help relieve pain and to treat the conditions causing your knee pain, such as rheumatoid arthritis or gout.
Therapy
Strengthening the muscles around your knee will make it more stable. Your doctor may recommend physical therapy or different types of strengthening exercises based on the specific condition that is causing your pain.
If you are physically active or practice a sport, you may need exercises to correct movement patterns that may be affecting your knees and to establish good technique during your sport or activity. Exercises to improve your flexibility and balance also are important.
