A simultaneous patellar tendon and anterior cruciate ligament (ACL) tear is an uncommon injury, resulting in limit of clear information for diagnosis and treatment. Therefore, the purposes of this case report are to share the data of this case and review literature to indicate process of investigation and treatment. A 33-years-old Thai male presented with severe right knee pain and cannot bear weight for 1 week, resulting from jumping from a high velocity vehicle. Marked swelling and ecchymosis at right knee could be observed during a physical examination and the patient was palpated a gap at patellar tendon area and could not extend his right knee. Initially, the preoperative planning was set as a direct end-to-end patellar tendon repair; however, a complete torn of anterior cruciate ligament (ACL) with body and posterior horn torn of lateral meniscus was found during intraoperative phase, and thus, the patient also underwent patellar tendon repair and open lateral meniscus repair.
