Pes anserine pain syndrome
In the acute setting, it is not important for a primary care or emergency medicine doctor to know if there is bursal involvement; pes anserine pain syndrome and pes anserine bursitis are approached similarly.
Patients with genu valgum (eg, being "knock-kneed") and who are obese may be at increased risk. This condition may occur more frequently in women, although any sex can be affected. Stiffness or tightness of the hamstrings contributes to the etiology of this condition.
Pes anserine pain syndrome can be associated with concomitant medial compartment knee osteoarthritis, medial collateral ligament injury (MCL), and medial meniscus tear of the knee.
