{Reference Type}: Case Reports {Title}: Reconstruction of a Neglected Patellar Tendon Rupture in an Adolescent: A Case Report. {Author}: Zigras F;Komnos GA;Hantes M; {Journal}: Cureus {Volume}: 16 {Issue}: 7 {Year}: 2024 Jul 暂无{DOI}: 10.7759/cureus.63844 {Abstract}: We present a case of a neglected patellar tendon rupture, misdiagnosed as an anterior cruciate ligament tear, in a 12-year-old child with open physis without an avulsion fracture. The patient was treated with an ipsilateral hamstring tendon autograft with preserved distal insertions, a transpatellar tunnel, and a transtibial fixation. At the final follow-up, the patient had a full range of motion and a fully functional knee. The described technique results in complete muscle strength, full range of motion, and pain-free gait. It can be used in chronic patellar tendon ruptures and is a valuable addition to the therapeutic quiver for this type of injury.
