<p>
Patients complain of knee pain just below medial joint line (esp with stairs)</p>
<p>
History may include sudden increase in running distance especially with hills (common)</p>
<p>
Associated with obesity, tight hamstring muscles and with knee OA</p>
<p>
PE: Tenderness to palpation of the bursa possibly with mild swelling</p>
<p>
DDx: MCL tear, medial meniscus injury, medial (knee) compartment arthritis, tibial stress fracture</p>
<p>
</p>
<p>
Treatment: Cessation/modification of offending activities, Icing and ice massage, NSAIDs, hamstring stretching and physical therapy. Failure of the above should prompt referral for bursal steroid injection.</p>
