An athletic 17-year-old man presents to the doctor with patellar knee pain (localized to anterior section), joint tenderness, and decreased range of motion that has developed steadily over the past 4-6 weeks. The patient notes that the knee pain is worst when he is playing basketball or when sitting down for prolonged periods of time. Patient can perform a straight leg raise during physical examination.
Is it patellar tendon rupture, patellar tendinopathy, lateral patellar compression syndrome, or patellofemoral pain syndrome?
