Osteoarthritis is a risk factor for the development of pes anserinus symptoms.ДЄn ultrasound examination identifies muscles, tendons and bursas, but it is known that this is not a reliable examination when it comes to pes anserinus symptoms. Additional examinations such as X-ray examination or ultrasound examination have no added value in the case of these symptoms.ДЄn X-ray examination can, however, be used to determine the degree of osteoarthritis in the knee. The above-mentioned criteria play an important role in this. The diagnosis is made by a (general) practitioner or physiotherapist on the basis of an interview and physical examination. Difficulty getting out of a chair or car.Morning stiffness at the location (of the pain) lasting at least one hour.Pain when walking up and down the stairs.The set criteria for the diagnosis include: As a result, it is difficult to distinguish if the pain originates from the pes anserinus, medial meniscus or medial knee ligament. Pain is often experienced over a larger area. The typical symptoms are not always present, and the location of the pain can be different for everyone. The pain often gets worse by walking up and down the stairs. The insertion sits below the knee on the medial side of the tibia. Typical symptoms include pain on the medial side of the knee and pain when pressing on the insertion of the tendons. Osteophyte formation (extra ossification on the medial side of the knee).Local trauma (accident, fall or making a wrong movement).Flatfeet (which can play a role in the position of the knee).Repetitive sports (running, cycling, swimming can cause excessive strain).Rheumatism (reduced quality of the muscles results in higher likelihood of wear and tear).Diabetes (reduced circulation so that tendons and bursas recover less quickly).Arthrosis of the knee (which can cause knock knee).Obesity (the pressure on the knees becomes too high and this can cause knock knee). Female gender (the pelvis is usually wider, developing into knock knee faster).

Risk factors for developing pes anserinus complaints The difference also has no added value because the treatment is the same in both cases. Hence, the term pes anserinus syndrome is used. The difference between tendinitis ( tendinopathy) or bursitis is difficult to be distinguish. A bursa is a bag filled with fluid that makes sure that different structures slide over one another. The space between this conjoined tendon and the tibia contains a bursa. Valgus stress is the inward caving of the knee, which is why it is also referred to as a knock knee. The function of these three muscles is mainly to bend and rotate the knee and to provide support in order to prevent valgus stress. The pes anserinus is formed by the tendons of three separate muscles: the gracilis, sartorius and semitendinosus.
