The patient was a 21-year-old male who was referred to physical therapy with a 1-week history of right knee pain and stiffness following an injury of traumatic onset. While attempting to jump off of both legs to dunk a basketball during a game, the patient heard and felt a pop in his right knee that was associated with an immediate onset of pain and swelling. He was unable to bear weight following the injury and, therefore, immediately went to the emergency department, where radiographs were completed and interpreted as negative for a fracture. However, the patella for the right knee was superiorly displaced. The patient was issued crutches and referred to physical therapy. At the time of the initial physical therapy examination, the patient was still not able to bear full weight on the right lower extremity or actively fully extend his right knee. Due to concern over possible meniscal, medial collateral ligament, or patellar tendon involvement, the patient's physician was contacted and magnetic resonance imaging was ordered. Five days later, the patient presented with decreased knee effusion and the special tests for the medial collateral ligament and meniscus were negative. However, the patient was still not able to actively extend his knee, suggesting a possible rupture of the patellar tendon, which was later confirmed on magnetic resonance imaging. Surgical repair of the patellar tendon was performed 2 weeks later.
