Pes Anserinus Tendinopathy

What is Pes Anserinus Bursitis?

Pes anserinus bursitis occurs when the pes anserine bursa becomes inflamed and painful.

A bursa is a small fluid-filled sac that helps reduce friction between tissues such as muscles, tendons, and bones. The pes anserine bursa is located on the inner side of the shin bone (tibia), just below the knee joint. It lies between three tendons — gracilis, sartorius, and semitendinosus — and the medial collateral ligament of the knee.

Bursitis refers to inflammation of a bursa, causing pain and swelling. Therefore, pes anserinus bursitis specifically describes inflammation of the pes anserine bursa, leading to pain on the inner side of the knee, particularly during activity or when pressure is applied.

How Does Pes Anserinus Bursitis Happen?

Pes anserinus bursitis commonly develops due to repetitive stress on the three tendons that attach near the inner knee — gracilis, sartorius, and semitendinosus. Activities such as running, golf, or basketball that repeatedly load these tendons can put pressure on the pes anserine bursa, leading to inflammation and pain.

Several factors can increase the risk of developing pes anserinus bursitis, including:ring muscles. Common causes include:

  • Injury to the medial collateral ligament (inside of the knee)
  • Osteoarthritis of the knee
  • Flat feet or other biomechanical problems
  • Obesity
  • Diabetes

What Are the Symptoms of Pes Anserinus Bursitis?

Pes anserinus bursitis usually develops gradually rather than suddenly. Common symptoms include:

  • Pain on the inner side of the knee or upper inner shin (tibia)
  • Swelling in the same area
  • Tenderness when touching the inner knee or upper inner shin

What Should I Do if I Have Pes Anserinus Bursitis?

If you suspect pes anserinus bursitis, it is important to seek physiotherapy. A physiotherapist can relieve pain, reduce inflammation, and prevent recurrence by addressing underlying biomechanical issues and strengthening surrounding muscles.

While waiting for professional care, you can help manage symptoms at home by applying ice to the affected area for 15–20 minutes every 1–2 hours. Use a bag of frozen peas or crushed ice wrapped in a damp cloth — never place ice directly on the skin.

What Shouldn’t I Do if I Have Pes Anserinus Bursitis?

If you suspect you have pes anserinus bursitis, it is important to stop activities that worsen your pain. These are usually sports or high-intensity exercises. Resting the knee allows the inflamed bursa to settle, preventing further damage and giving physiotherapy treatment the best chance to be effective.

Physiotherapy Treatment for Pes Anserinus Bursitis

Physiotherapy is highly effective in treating pes anserinus bursitis and preventing recurrence. A tailored programme may include:

  • Stretching Exercises: To improve flexibility of the hamstrings and surrounding muscles.
  • Strengthening Exercises: To support the knee and reduce stress on the bursa.
  • Biomechanical Treatment: Including gait re-education and orthotics such as insoles to correct foot or leg mechanics.
  • Education: Guidance on safe activity and exercise to prevent future flare-ups.

Could There Be Any Long-Term Effects from Pes Anserinus Bursitis?

When properly diagnosed and treated, pes anserinus bursitis rarely causes long-term effects. Physiotherapy not only treats current symptoms but also provides strategies to reduce the risk of recurrence, allowing you to return to activity safely and confidently.
