Patient Presentation:
A 14 year old, previously healthy male golfer and basketball player presented to an orthopedic knee clinic with 1 week of worsening right lateral knee pain.

The pain started on the first day of basketball tryouts and progressively worsened over the next three days, finally causing him to sit out of basketball on day 4 of tryouts. The pain localized just proximal to his lateral femoral condyle and was described as sharp, non-radiating and 9/10 in severity. The pain was first noticed during a set of lunges. There was no twisting, trauma, popping, catching, locking, or giving-way episodes. HIs pain was worsened by running, especially downhill. After practice walking was painful, and he observed a small amount of swelling. The pain would keep him up at night. Ibuprofen had provided some pain relief, and his pain had improved slightly since sitting out of basketball tryouts over the last four days.
