Traumatic avulsion of the anterior medial meniscus root combined with PCL injury: a case report Anqi Wang and Hongzhang Lu*
Abstract Background: Avulsion of the anterior medial meniscus root (AMMR) has a low incidence rate, especially when it is combined with posterior cruciate ligament (PCL) injury, which hasn’t been reported in any literature to date. The aim of this study was to share our experience in the diagnosis and treatment of a patient with traumatic avulsion of AMMR combined with PCL injury. Case presentation: This article reports a 26-year-old male patient diagnosed with traumatic avulsion of the AMMR with PCL injury. After arthroscopic surgery, he achieved remission of symptoms and recovery of functions. Conclusions: Anterior meniscus root injuries are relatively rare. Its diagnosis can be made preliminarily based on clinical manifestations, physical examinations, and magnetic resonance imaging (MRI), and then confirmed by arthroscopic exploration. Arthroscopic suture anchor fixation of the injured anterior meniscus horn shows a good therapeutic effect. Keywords: Meniscus root avulsion, PCL injury, Meniscal repair, Suture anchor
Background Meniscus tear, a common condition in young and middle-aged adults, has a mean annual incidence of 9.0 per 10,000 in men, and 4.2 per 10,000 in women [1]. The avulsion of the posterior medial meniscus root (PMMR) occurs more often than that in the AMMR, and therefore most of the available studies have focused on PMMR avulsion [2–5]. So far, only a few cases of AMMR avulsion have been reported that were caused by iatrogenic factors [6], or anatomical variation and combined with anterior cruciate ligament (ACL) injury [7, 8]. No reports of AMMR avulsion combined with PCL injury have been found yet. In this case study, we report a 26year-old man with traumatic avulsion of the AMMR complicated with PCL injury. The purpose of this study was to

share our experience in the diagnosis and treatment of this rare condition.
Case presentation A 26-year-old male patient was referred to our clinic for pain in the right knee while walking, and being unable to run or jump for 6 weeks, after a jump landing on flat ground. Since the injury, he had received immobilization of the injured knee in extension position for 4 weeks with a hinged knee brace and crutches, then tried flexion and loading weight without the brace for 2 weeks, which however, did not relieve the pain effectively. Physical examinations on admission showed effusion of the injured knee, tenderness in the anteromedial aspect of the knee, and deep anterior knee pain when the flexion angle was greater than 40°. In addition, a positive McMurray test and grade I° posterior instability were found without unstable collateral ligaments. Coronal view of MRI showed protrusion of medial meniscus at the front of the injured knee
