The patient states it started yesterday and has been steadily worsening. She recently joined a volleyball team to try to get into shape as she was informed that weight loss would be beneficial for her at her last physical exam. She states that she has been repetitively pivoting and twisting on her knee while playing volleyball. The patient has a past medical history of polycystic ovarian syndrome and is currently taking oral contraceptive pills. Her temperature is 98.5F 36.9C, blood pressure is 13788 mmHg, pulse is 90min, respirations are 12min, and oxygen saturation is 98 on room air. Physical exam reveals an obese woman with facial hair. Physical exam is notable for tenderness that is mediated with palpation over the medial aspect of the tibia just inferior to the patella. Her BMI is 37 kgm2. The rest of the exam of the lower extremity is not remarkable. Which of the following is the most likely diagnosis?? A: Medial collateral ligament tear, B: Medial meniscus tear, C: Osteoarthritis, D: Patellofemoral syndrome, E: Pes anserine bursitis,  <response>: This is a clinical vignette describing a 23-year-old obese woman with knee pain that started after playing volleyball. The key findings on history and physical exam are:- Acute onset of knee pain after repetitive pivotingtwisting while playing volleyball - Tenderness medial to the patella inferior to the joint line- No other abnormalities on exam of the kneeBased on the acute onset after injury and the location of tenderness, this presentation is most consistent with pes anserine bursitis. The pes anserine bursa is located on the medial side of the knee below the joint line, where the patient is tender. Acute inflammation of this bursa can occur with overuse from sports that require repetitive knee flexion, like volleyball. The other choices are less likely:- Medial collateral ligament MCL tear would cause tenderness directly over the MCL.- Medial meniscus tear could cause medial knee pain but there is no poppingcatching. - Osteoarthritis would not present acutely after an injury.- Patellofemoral syndrome typically causes anterior knee pain, not medial.E: Pes anserine bursitis
