18-year-old male with right knee pain in the musculo- tendinous junction and tendinous insertion of rectus femoris. Symptoms began during a baseball game on 2/19/2018 (patient is the catcher on his high school team). Pain was the worst when he would try standing up from his squatting position. As the week progressed, the pain intensity decreased from 6–7/10 (VAS) to 4–5/10, mainly with squatting/lunging movements.
