PATIENT PRESENTATION
A 33-year-old female presents with left lateral knee pain following being kicked in the medial left knee during a karate class 1 week ago. The patient reports the pain is worse with trying to use the left leg as a stance leg during kicks and with trying to get out of the car, especially from the driver’s seat. She denies popping, clicking, or giving way in the knee, but does report feeling less stable when performing karate moves that involve standing on the left leg only. There is mild swelling and moderate tenderness in the lateral knee. Range of motion is full with pain at end range extension. There is no pain with resisted knee flexion or extension, but hip abduction in side lying does reproduce pain. Patellar instability testing is negative, but varus stress test is positive for pain with a firm end feel and no apparent laxity.
