Posterior root avulsions of the medial and lateral menisci result in decreased areas of tibiofemoral contact and increased tibiofemoral contact pressures. These avulsions may lead to the development of osteoarthritis. Therefore, two surgical techniques, the transtibial pullout repair and the suture anchor repair, have recently been developed to restore the native structure and function […]
Posterior medial meniscal root tears have been reported to extrude with the meniscus becoming adhered posteromedially along the posterior capsule. While anatomic repair has been reported to restore tibiofemoral contact mechanics, it is unknown whether nonanatomic positioning of a meniscal root repair to a posteromedial location would restore the loading profile of the knee […]
Current methods of the transtibial pull-out meniscal root repair significantly displace under cyclic loading in porcine models but have not been evaluated in human models. One potential explanation for the displacement is that a single transtibial tunnel may not fully restore the attachment of the entire posterior medial meniscal root.
The purpose of this study […]
Recent biomechanical evidence suggests that the meniscus-suture interface contributes the most displacement to the transtibial pull-out repair for meniscal root tears. Therefore, optimization of surgical technique at the meniscus-suture interface may minimize displacement and improve the strength of meniscal root repairs.
The purpose of this study was to investigate the cyclic displacement and ultimate failure […]
Meniscal root tears present in many forms and can have profound consequences on the health of knee articular cartilage. While the biomechanics, natural history, and treatment of root tears have been increasingly investigated, the spectrum of meniscal root tear patterns observed during arthroscopic examination has yet to be defined and categorized. The purpose of this […]
This study presents the first reported case of iatrogenic injury to the anterior medial meniscal root attachment following intramedullary nailing for a tibial shaft fracture. The patient experienced a closed right tibia-fibula fracture 7 years prior to presentation, which was treated with a reamed intramedullary nail. Experiencing chronic anterior knee pain, the nail was […]
An avulsion of the posterior root attachement of the lateral meniscus or a radial tear close to the root attachment can lead to degenerative knee arthritis. The study hypothesized that in situ pull-out suture repair of lateral meniscus root avulsions and of complete radial tears 3 and 6 […]
Detachment of the meniscal roots from their tibial posterior attachements can cause meniscal extrusion and joint space narrowing, and has been associated with knee arthritis. This study analyzes a series of cases in which the posterior horn meniscal roots were detached iatrogenically because of malpositioning of the transtibial PCL […]
The study compared the mechanical characteristics of meniscal repair fixation using horizontal sutures and six different sutures under submaximal cyclic and load to failure test conditions. The purpose fo this study is to help aid physicians in selecting a suture type.
This manuscript went into specific detail about the attachment sites of the posterior roots of the medial and lateral meniscus. This is a very hot topic currently, and this is the first study to actually define in detail where the attachment sites are located. This information is very important because it is well recognized that tears […]
