Surgical reattachment of medial meniscus posterior root tear (MMPRT) with transtibial sutures can delay the presenceof medial knee joint compartment osteoarthritis. Most suture configurations are placed five mm away from the tornmargin in the meniscal substance which is already degenerated and may decrease the pull out strengths of repairconstruct. The number of meniscus penet...

Background: Meniscus tear is a common finding in patients with anterior cruciate ligament (ACL) injury and may affectthe natural history of the injury and the outcomes of treatment. In the current study, the characteristics of meniscus tearsin patients who underwent arthroscopic ACL reconstruction were investigated.Methods: The hospital records of 1022 patients were reviewed. ...

The meniscus roots are critical for meniscus function in preserving correct knee kinematics and avoiding meniscus extrusion and, consequently, in the progression of osteoarthritis. Several techniques exist for medial meniscus posterior root tear repair; however, current surgical techniques have been proved to fail to reduce meniscus extrusion, which has been shown to be associated with developm...

Meniscal root tears are defined as radial tears located within 1 cm from the meniscal attachment or a bony rootavulsion. This injury is biomechanically comparable to a total meniscectomy, leading to compromised hoop stressesresulting in decreased tibiofemoral contact area and increased contact pressures in the involved compartment.These changes are detrimental to the articular cartilage and ult...

The posterior lateral meniscus root (PLMR) provides the circumferential tension required to stabilize the lateral meniscus. Thus, preservation of the PLMR is important to prevent an increase in tibiofemoral contact pressure, which could result in osteoarthritis. We describe an all-arthroscopic approach to the fixation of PLMR using suture anchors through associated posterolateral arthroscopic p...

PURPOSE To retrospectively determine the prevalence of posterior lateral meniscus root tears (LMRTs), as depicted on magnetic resonance (MR) images, in patients with an anterior cruciate ligament (ACL) tear and to investigate the association of LMRTs with lateral meniscus extrusion and other ligament injuries. MATERIALS AND METHODS Institutional review board approval was obtained; informed co...

BACKGROUND Complete radial tears near the medial meniscus posterior root attachment site disrupt the circumferential integrity of the meniscus (similar to a posterior root avulsion). These tears can compromise the circumferential integrity, and they have been reported in biomechanical studies to be comparable with the meniscectomized state. PURPOSE To quantify the tibiofemoral contact pressur...

BACKGROUND An avulsion of the posterior root attachment of the lateral meniscus or a radial tear close to the root attachment can lead to degenerative knee arthritis. Although the biomechanical effects of comparable injuries involving the medial meniscus have been studied, we are aware of no such study involving the lateral meniscus. We hypothesized that in situ pull-out suture repair of latera...

BACKGROUND Ultrasound techniques have been utilized for detection of discrete meniscus tears and extrusion. Meniscal extrusion is associated with increased contact pressure and decreased contact area contributing to the advancement of knee osteoarthritis. The purpose of this biomechanical study was to detect meniscal extrusion using a clinically available, portable ultrasound device. And furthe...
