What is Pes Anserine Tendinitis and How to Manage It

Generally, pes anserine tendonitis may be caused by degenerative changes of the pes anserine tendon, overuse, trauma, tendon atrophy, diabetes, and other factors. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific explanations are as follows:

1. Degenerative changes of the pes anserine tendon: With aging, the Achilles tendon may undergo degenerative changes, leading to narrowing of the sheath-like structure around the pes anserine tendon, increased pressure, and subsequent inflammation. Sufficient rest is recommended to avoid overuse of the joints or limb movements that cause pain. For example, reducing prolonged walking, climbing stairs, and other activities can provide time for tendon recovery.

2. Overuse: Long-term engagement in repetitive or high-intensity activities, such as in athletes or laborers who regularly perform strenuous muscular work, can easily lead to tendon wear and inflammation of the pes anserine muscle group. It is recommended to immediately stop activities that cause pain, rest sufficiently, and avoid further injury.

3. Trauma: Trauma may cause soft tissue damage; if not treated promptly or rehabilitated properly, it may lead to pes anserine tendonitis. Additionally, if an open wound is not properly managed, bacteria may enter the body through the skin and spread to surrounding tissues, causing infection. Immediate irrigation with clean water or saline to remove surface dirt and debris from the wound is recommended, followed by gentle disinfection with an agent such as povidone-iodine to prevent worsening of the infection.

4. Tendon atrophy: The pes anserine tendon is formed jointly by the sartorius, gracilis, and semitendinosus muscles, along with plantar flexor muscle groups. Factors such as strain or trauma may lead to muscle atrophy, dysfunction, or damage, thereby causing pes anserine tendonitis. Electrical stimulation therapy using specialized equipment at professional medical facilities can be used to stimulate muscle contraction, activate muscle function, and aid in muscle recovery.

5. Diabetes: Genetic factors and unhealthy lifestyle habits may lead to diabetes. A state of hyperglycemia may increase the risk of nerve and vascular damage, and over time, complications such as diabetic foot may develop, subsequently affecting the health of the pes anserine tendon. Primary diseases should be actively treated, blood glucose strictly controlled, and maintained within the target range through proper diet and regular exercise.

Cold weather may exacerbate symptoms of pes anserine tendonitis. Therefore, it is important to keep warm and avoid chilling of the knee joints during cold seasons.
