A 17-yeаr-оld pаtient is referred tо PT with а histоry of bilateral knee pain (R>L). They are very active within the school year, participating in 3 sports throughout the year. They have noticed the pain is worse during track season (long-distance runner). The pain is localized under the kneecap. The patient denies a history of swelling and mechanism of injury, but states that the pain is gradually worsening over the last couple months.
