What Is Pes Anserine Bursitis?

Pes anserineis the inflammation disease of pes anserine in the inner part of the human knee. The pain caused by this disease is medial. 

Pesanserinus actually is the inner area of knee joint where there is a shine bone. Shine bone is the point behind the knee joint where three tendons muscles attach. 

The spot where these muscles join forms a webbed foot form making a single tendon. This tendon gets attached with shine bone. 

Three muscles which form a single tendon on the shine bone are:


It is one of the most massive muscles in the human body that runs down and across a thigh to make hip and thigh movement smooth. 

sartorius muscle


It is a hip muscle which helps in leg movements. It lets the leg draw inwards. 



It is the hamstring muscle in the human body, which helps in bending the knee in its right position. Gracilis and Sartorius combine with semitendinosus to form a tendon. 


Inside the conjoined tendon formed by all these muscles, there is the pes anserine bursa. This Bursa is a small bag type substance that gets filled with liquid. Bursa is there behind the knee joint to control the level of friction among the tibia and the tendon. 

This fraction needs to get reduced as high fraction among these two can make you knee movements tough for you. As the fraction is reduced, your knee bones can remain strong.  This reduced fraction provides more cushioning to the tendons. It also smooth’s knee movements and prevent your knees from inflammation.

What actually causes Pes anserine pain?

Increased friction and more stress on the knee joint areas where these three muscles combine to cause inflammation in pes anserine. This inflammation gradually starts causing pain.

The pain in the start is not too intense, but as the knee activities keep on increasing, the pain worsens. 

Once the bursa is inflamed, it starts creating more fluid, and this leads to the swelled bursa. It also creates excessive pressure on knee joint surrounding structures. 

Below are the common reasons for pes anserine:

The muscles combined on the shine bone work collaboratively to make natural knee movements. When the muscles get used repetitively without providing much rest to them, they start creating more friction.

2. Muscle Tightness

If muscles around knee or hip are weak or tightened, this issue of pes anserine can arise. This tightness in muscles puts extra pressure on the tendons and this pressure damages the tendons.

6. Obesity

Obesity is one of the most common causes of excess weight and inflammation on the knee bursa and causes pes anserine.
