What is Pes Anserinus Bursitis/Tendonitis?
Pes Anserinus is the area on the inside of the knee where the tendons for the gracilis, sartorius and semitendinosus muscles attach. Under these tendons
is a bursa (fluid filled sac) which is important in reducing friction between the tendons and the bone.
Pes anserinus tendonitis refers to inflammation of the gracilis, sartorius and semitendinosus tendons. Pes anserinus bursitis is the name given to inflammation
of the underlying bursa. Due to their close anatomical relationship, these conditions often occur simultaneously.
What Causes Pes Anserinus Bursitis/Tendonitis?
There are a variety of factors which can cause (or place you at a higher risk of developing) pes anserinus bursitis/tendonitis, including:
- Activities/sports which involve repetitive use of the sartorius, semitendinosus and gracilis tendons such as: running, dancing and sports which require
a lot of direction changes (e.g. soccer, basketball)
- Abnormal hip, knee or ankle biomechanics
- Underlying knee pathology (e.g. OA)
- Inadequate warm-up and stretching prior to and following exercise
- Muscle imbalances
- Inappropriate footwear
- Sudden increase in activity level/sports training
What are the Symptoms of Pes Anserinus Bursitis/Tendonitis?
You may experience one or more of the following:
- Pain in the inner knee with knee bending and/or straightening
- Inner knee pain when going up or down stairs
- Weakness or feeling of giving way around the knee
- Swelling over the inside aspect of the knee
- Decrease in knee range of motion due to pain
How is Pes Anserinus Bursitis/Tendonitis Diagnosed?
On examination, your physiotherapist or sports doctor will look for signs of pes anserinus bursitis and tendinitis.
An MRI or diagnostic ultrasound may also be used to confirm the diagnosis.
What is the Treatment for Pes Anserinus Bursitis/Tendonitis?
Many patients with pes anserinus bursitis and tendonitis start to feel better within a few weeks of the injury. Your physiotherapy treatment will aim to:
- Reduce pain and inflammation.
- Normalise joint range of motion.
- Stretch tight muscles around the knee
- Strengthen your knee: especially quadriceps (esp VMO) and hamstrings.
- Strengthen your lower limb: calves, hip and pelvis muscles.
- Improve patellofemoral (kneecap) alignment
- Normalise your muscle lengths
- Improve your proprioception, agility and balance
- Improve your technique and function eg walking, running, squatting, hopping and landing.
- Minimise your chance of re-injury.
However, we strongly suggest that you discuss your knee injury after a thorough examination from a knee injury clinician such as a sports physiotherapist,
sports physician or knee surgeon.
The majority of people with pes anserinus bursitis and tendonitis will make a full recovery with conservative physiotherapy treatment. An injection into
the site of inflammation is sometimes also required to decrease pain and inflammation.
How to Prevent Pes Anserinus Bursitis/Tendonitis?
There are a variety of ways to reduce your risk of developing pes anserinus bursitis/tendonitis. These include:
- Correction of exercise technique
- Adequate warm-up and cool down before and after exercise
- Correction of muscle imbalances
- Appropriate footwear during exercise
- Gradual increase in training intensity/quantity
Return to Sports with Pes Anserinus Bursitis/Tendonitis?
It is important athletes who have experienced pes anserinus bursitis/tendonitis complete a full rehabilitation program to prevent recurrence or ongoing
issues. This will include a graduated return to your sport program.
For more information, please ask the advice of your physiotherapist.
