Pes Anserine Bursitis
Pes anserine bursitis, also known as pes anserine tendinobursitis or anserine bursitis, is a condition characterized by inflammation of the pes anserine bursa located on the inner side of the knee, just below the knee joint. This condition typically causes pain and tenderness in the area where the tendons of the hamstring muscles insert into the shinbone (tibia).
1. Overuse or Repetitive Stress: Activities that involve repeated bending and straightening of the knee, such as running, cycling, or stair climbing.
2. Muscle Imbalances: Weakness or tightness in the muscles of the thigh and lower leg, particularly the hamstrings, quadriceps, and calf muscles.
3. Obesity: Excess body weight can increase stress on the knee joint and contribute to bursitis.
4. Poor Biomechanics: Abnormalities in walking or running gait that affect knee alignment and mechanics.
5. Direct Trauma: Injury or blow to the inner side of the knee.
6. Osteoarthritis: Degenerative changes in the knee joint can sometimes lead to bursitis.
1. Pain: Deep, aching pain on the inner side of the knee, just below the joint. Pain may worsen with activities that stress the knee, such as climbing stairs or getting up from a chair.
2. Tenderness: Localized tenderness over the pes anserine bursa, which may be sensitive to touch.
3. Swelling: Mild to moderate swelling over the inner knee.
4. Stiffness: Difficulty fully straightening or bending the knee due to discomfort.
5. Pain at Rest: In some cases, pain may be present even at rest, especially if the bursa is significantly inflamed.
