Meniscus Studies

2018 AJSMComplete radial tears of the medial meniscus have been functionally described as being similar to a total meniscectomy, and they represent a challenging problem to treat. Without treatment, radial tears of the medial meniscus can lead to rapid joint [...]

2017 AJSM Osteonecrosis of the knee is a debilitating disease that can progress to end-stage osteoarthritis. Spontaneous osteonecrosis of the knee (SONK or SPONK) is 1 of 3 categories that are used to substratify osteonecrosis, the other 2 being secondary [...]

The meniscus was once considered a functionless remnant of muscle that should be removed in its entirety at any sign of abnormality. Its role in load distribution, knee stability, and arthritis prevention has since been well established. The medial and [...]

2017 AJSM Menisci are crescent-shaped, fibrocartilaginous wedges that play an important role in complex knee mechanics and function. The menisci are primarily responsible for distributing loads through the tibiofemoral joint, joint stabilization, and congruency. The circumferential collagen fibers in the [...]

2017 AJSM Complete radial meniscus tears constitute a unique subset of meniscus injuries, resulting in disruption of the circumferential fibers and compromising their ability to with-stand hoop stresses. This results in decreased contact area and increased tibiofemoral contact pressure, which [...]

The purpose of this review was to summarize recent advances in the diagnosis and treatment of meniscus root tears. Over the past decade, meniscal root tears have become increasingly recognized as a significant source of pain and disability. Meniscal root [...]

AJSM 2016 Background: Outcomes after transtibial pull-out repair for posterior meniscal root tears remain underreported, and factors that may affect outcomes are unknown. Purpose/Hypothesis: The purpose of this study was to compare patient-centered outcomes after transtibial pull-out repair for posterior [...]

2016 OJSM Meniscal ramp lesions are more frequently associated with anterior cruciate ligament (ACL) injuries than previously recognized. Some authors suggest that this entity results from disruption of the meniscotibial ligaments of the posterior horn of the medial meniscus, whereas [...]

AJSM 2015 Complete radial tears of the medial meniscus have been reported to be functionally similar to a total meniscectomy. At present, there is no consensus on an ideal technique for repair of radial midbody tears of the medial meniscus. [...]

2015 Springer The purpose of this study was to investigate associated pathologies identified at arthroscopy in patients with meniscus root tears. This study was Institutional Review Board approved. All patients who underwent arthroscopic knee surgery where a complete meniscus root tear [...]

JAAOS 2015 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 [...]

AJSM 2015 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 [...]

AJSM 2015 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 [...]

AJSM 2015 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 [...]

AJSM 2014 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 [...]

KSSTA 2014 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, [...]

THE JOURNAL OF BONE AND JOINT SURGERY 2014 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 [...]

THE JOURNAL OF BONE AND JOINT SURGERY 2014 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 [...]

THE KNEE 2013 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 [...]

AJSM 2012 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 [...]

AJSM 2010 Symptomatic early-onset chondromalacia often develops after a meniscectomy in the affected knee compartment. The role of meniscal transplantation in reducing pain and improving function in patients with prior ipsilateral meniscectomy is still being defined. Download Full Article
