Sartorius Distal Insertion Bursa

Region: Thigh
Clinical Relevance

Clinical Notes

Sartorius distal bursitis is part of the pes anserinus bursitis complex producing medial knee pain inferior to the joint line in obese, osteoarthritic, or diabetic patients. It is distinguished from MCL sprain by its more distal location and absence of valgus stress pain. Ultrasound identifies the bursa between the tendon and tibia. Weight loss, stretching, and injection are the primary management approaches.
