What causes knee bursitis or tendonitis of the knee?

Knee bursitis and tendonitis are common knee injuries. They are caused by repetitive stress on the knee or by a direct blow to the knee. These conditions are often associated with overuse, trauma, or inflammation of the bursa or tendon.

Bursitis of the knee is inflammation of the bursa, a small fluid-filled sac that cushions the knee joint. It can be caused by repetitive motion, such as kneeling or squatting, or by a direct blow to the knee.

Tendonitis of the knee is inflammation of the tendon, which is a thick band of tissue that connects muscle to bone. It can be caused by overuse, such as running or jumping, or by a sudden injury, such as a fall.

Symptoms of knee bursitis or tendonitis may include pain, swelling, redness, and limited mobility. Treatment may include rest, ice, compression, and elevation of the affected knee, as well as physical therapy and medication to reduce inflammation. In some cases, surgery may be necessary to repair the damaged tissue. It is important to seek medical attention if you suspect that you have knee bursitis or tendonitis, as these conditions can worsen if left untreated.
Knee bursitis and tendonitis are common conditions that can cause pain and inflammation in the knee joint. Here are the common causes of knee bursitis and tendonitis:

**Knee Bursitis:**

Bursitis is the inflammation of the fluid-filled sacs (bursae) that cushion the joints and reduce friction between moving parts. In the knee, there are several bursae that can become inflamed, leading to knee bursitis.

Common causes of knee bursitis include:

1. **Overuse or repetitive strain**: Repeatedly bending, kneeling, or squatting can cause friction and irritation to the bursae, leading to inflammation.
2. **Direct blows or trauma**: A fall or direct blow to the knee can cause bursitis.
3. **Infection**: Bacterial or fungal infections can cause bursitis, especially in people with weakened immune systems.
4. **Gout or rheumatoid arthritis**: These conditions can increase the risk of developing bursitis.
5. **Poor posture or biomechanics**: Abnormal movement patterns or poor posture can put additional stress on the knee joint, leading to bursitis.

**Knee Tendonitis:**

Tendonitis is the inflammation of the tendons, which connect muscles to bones. In the knee, the quadriceps and patellar tendons are commonly affected.

Common causes of knee tendonitis include:

1. **Overuse or repetitive strain**: Sudden
