Anterior cruciate ligament remnants nodule: potential factor causing extension loss Abstract: Backgroud Extension loss caused by Anterior Cruciate ligament (ACL) remnants nodule was usually reported by case report. There is no systematic report analyzing ACL remnants nodule. The purpose of this study was to investigate the characteristics of extension loss caused by remnants of anterior cruciate ligament (ACL) after injury. Methods From June 2008 to December 2011, ACL remnant were observed by arthroscopy in 1012 cases with ACL injuries at the time of primary reconstruction. ACL remnants nodules were recorded. The time of extension loss occurrence caused by ACL remnants nodule, associated symptom and sign, Magnetic resonance imaging (MRI), and arthroscopic findings were observed. Histological examination was performed on the lesion resected. Results 24 cases with ACL remnants nodules were found by arthroscopy. Among them extension loss caused by remnants of ACL happened in 19 c
