“…Meniscal posterior root avulsions result in a significant increase in peak contact pressure and decreased contact areas in comparison with the intact knee. 12 , 22 , 23 , 24 , 25 Two studies also reported a significant increase of meniscal extrusion and gap formation after meniscus root injuries compared to intact and repaired roots. 1 , 26 …”

ObjectivesThe aim of this study was to analyze the effect of tibial tunnel positioning in single bundle and double bundle ACL reconstructions on lateral meniscus anterior root.MaterialsTwelve single knee cadavers were used, 6 for a single bundle ACL reconstruction, which were reamed gradually starting from 8 mm, 9 mm and ended with a 10 mm reamers, while the other 6 were prepared for a double bundle ACL reconstruction in which 7 mm reamer for the AM tunnel and 6 mm reamer for the PL tunnel were used. After drilling, changes of lengths and thicknesses of anterior horns of the lateral menisci were recorded.ResultsBefore drilling, the groups were homogenous for the lateral menisci dimensions. After drilling, no statistically significant difference was noticed between the two groups. However, in single bundle group, 2 anterior horns width injury (1.44 mm and 2.13 mm) with the 9 mm reamer and 3 anterior horns width injury (2.51 mm, 3.55 mm and 4.28 mm) with the 10 mm reamer were recorded. However in double bundle group a single anterior horn width injury (2.82 mm) was recorded.ConclusionUsing a greater size reamer in single bundle reconstruction, causes a relatively higher risk of lateral meniscal anterior root injury. Lateral meniscus stability should be examined arthroscopically after reaming with large reamers.

“…Comparing to posterior meniscus root injury, fewer cases of anterior meniscus root injury have been reported due to its low incidence rate. In 2007, Navarro-Holgado and colleagues [8] reported two cases of anterior medial meniscus detachment associated with tearing of the ACL, to which the anatomic variation of the AMMR attachment sites was thought to have contributed. Both of the patients received arthroscopic partial meniscectomy and ACL reconstruction.…”

“…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.…”

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.

“…Aus klinischer Sicht würden die hier gefundenen geringen Kräfte in den meniskotibialen Bändern darauf hindeuten, dass keine sehr rigide Verankerung notwendig ist. So würden beispielsweise bei moderaten Rehabilitationsmaßnah-men nach Refixierung einer Meniskushornavulsion keine übermäßigen Belastungen auf das refixierte Meniskushorn ausgeübt werden [17]. Andererseits wurde beschrieben, dass die Integrität der Meniskuskörper-Ligament-Verbindung unbedingt gewährleistet sein muss, da deren Verlust aus biomechanischer Sicht einer Meniskektomie gleich kommt [19].…”

“…Zudem bleibt weiterhin unklar, welche Lasten über die meniskotibialen Ligamente während kurzzeitig einwirkender, stoßförmiger Meniskusbelastungen übertragen werden. In einem solchen Fall könnten höhere Belastungen in den Bändern auftreten [17], was letzten Endes die hohen Reißkräfte der Ligamente erklären würde. Interessenkonflikt.…”
