Knee pain is a common problem with many causes, from acute injuries to complications of medical conditions. A joint is formed by two or more bones that are connected by thick bands of tissue called ligaments. The knee is the largest joint in the body. Knee is made up of three main parts:
- The kneecap
- The upper end of the shin bone
- The lower end of the thigh bone
Knee pain is a common problem that can originate in any of the bony structures compromising the knee joint, the kneecap, or the ligaments and cartilage of the knee. Knee pain can affect people of all ages. Thorough physical examination will usually establish the diagnosis of knee pain
A thorough physical examination will usually establish the diagnosis of knee pain. Gout occurs when a substance called uric acid gathers in the knee, causing sharp pain. Pseudogout strike the knees after crystals of calcium pyrophosphate build up in the joints.
Another condition that causes knee pain is when your kneecap becomes dislocated. Instead of resting in its normal location in a notch at the bottom of your thigh bone, it moves to the side, typically toward the outside edge of your knee. This often occurs when a person is bearing the full body weight on one foot and twists or changes directions quickly.
One of the most common causes of knee pain and loss of mobility is the wearing away of the joint’s cartilage lining. The most common cause is a condition known as osteoarthritis.
Some of the other findings that accompany knee pain are
- Due to instability of the knee difficulty walking,
- limping due to discomfort,
- Redness and swelling,
- locking of the knee,
- Difficulty down steps due to ligament damage.
