Surgical management of pes anserine bursitis is very rarely warranted. Surgery is usually indicated when an immunocompromised patient has a localized infection that does not resolve with standard antibiotic treatment. Surgical decompression of the bursa may be performed in such cases.

Clinically, pes anserine bursitis can mimic distal anteromedial knee disorders or internal derangement of the knee, sometimes leading to unnecessary surgery. In an investigation of 509 magnetic resonance imaging (MRI) studies done on patients thought to have an internal knee derangement, the prevalence of pes anserine bursitis was found to be 2.5%. [16]

In cases of disability, such as those causing 6-8 weeks of limitation in athletes, some surgeons advocate resection, especially if mature exostosis is present and causing irritation. The operation includes excision of the bursa and any bony exostosis.
