Patient Presentation:
A 23 year old collegiate volleyball player presented to the clinic with a 5 day history of left knee pain.
History:
The pain began after she was playing volleyball, dove for the ball, and hyperflexed her knee. She subsequently felt a pop, which led to significant pain. She then collapsed to the floor and had difficulty ambulating. She was unable to finish the game and has since had worsening pain and swelling of her left knee. Since the injury, she has been unable to bear weight and has been using crutches to ambulate. The pain was initially in the posteromedial aspect of the left knee, but has become more lateral. She described the pain as a throbbing, achy, 8/10 level which improved with rest and was exacerbated with walking. She tried a knee brace and ibuprofen without relief. The patient also had a previous left knee anterior cruciate ligament (ACL) reconstruction surgery in 2020.
