Pes Anserine Bursitis
The bursae refer to the small, jelly-shaped sacs found all over the body, such as around the shoulder, elbow, knee, hip and heel. These sacs have a small volume of fluid and sit between bones and soft tissues to act as cushions that minimise friction.
Pes anserine bursitis is a condition associated with the inflammation of the bursa situated between the tibia (shinbone) and the 3 tendons of the hamstring muscle on the inner side of the knee. This condition develops when the bursa gets irritated, leading to excess fluid production. In turn, this causes swelling and increased pressure on surrounding knee structures.
A common indicator of pes anserine bursitis is pain and tenderness on the inner knee.
Symptoms of Pes Anserine Bursitis
Pes anserine bursitis presents with the following symptoms:
- Gradual onset of pain on the knee’s inner side or at the shinbone’s centre, about 2 to 3 inches beneath the knee joint.
- Increased pain when climbing stairs or even exercising.
- Swelling, puffiness or tenderness when touching the affected area.
Causes
Pes anserine bursitis often develops due to overuse, friction or repeated strain on the bursa. It is especially common among athletes (mostly runners) and individuals with knee osteoarthritis.
Some of the factors that can increase the risk of developing this condition entail:
- Poor training habits, such as inadequate stretching, excessive hill running, or sudden increases in running distance.
- Tight hamstring muscles.
- Excess body weight.
- Structural issues, such as having knock knees or being duck-footed.
- Knee osteoarthritis
Diagnosis
During your visit, the GP will assess your knee and discuss your symptoms to determine the cause of your discomfort.
Since pes anserine bursitis can present symptoms similar to a stress fracture thus, an X-ray is often needed for an accurate diagnosis. Additionally, the condition may resemble a medial meniscus tear; hence, careful evaluation is required to distinguish between them.
Treatment of Pes Anserine Bursitis
Pes anserine bursitis is usually managed with non-surgical treatments. Athletes should adjust their workout routines to prevent the condition from recurring.
Common treatment approaches are:
- Rest: Avoid activities that aggravate the condition and consider alternative exercises until the inflammation subsides.
- Ice therapy: Apply ice to the affected area 3–4 times daily for 20 minutes per session. Always use a barrier such as a cloth in order to avoid direct skin contact.
- Anti-inflammatory drugs: Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, aspirin, or naproxen can help reduce pain and swelling. Topical NSAIDs, such as diclofenac gel, may also provide relief.
- Corticosteroid injection: Your physician may administer an anaesthetic and steroid injection directly into the bursa for quick symptom relief.
- Physical therapy: A structured rehabilitation program may include stretching exercises, ice therapy, and ultrasound treatments to aid recovery and prevent recurrence.
Bottom Line
Pes anserine bursitis usually causes significant discomfort that can impact day-to-day activities. However, addressing risk factors, modifying activity levels, and following a tailored treatment plan can relieve pain and prevent future flare-ups.
