BACKGROUND Injury patterns of the meniscus following impact trauma resulting in anterior cruciate ligament (ACL) rupture are not well understood. This study explored the spatial and temporal distribution of meniscal tears in a novel in vivo lapine model. METHODS Skeletally mature Flemish Giant rabbits were subjected to either tibiofemoral impaction resulting in ACL rupture or surgical ACL tra...

Abstract— Knee joint is very complex and delicate joint in human body structure. Due to weight load, stress, knees can be injured and damaged and Osteoarthritis (OA) is one of the common diseases of knee injury. It is a degenerative joint disease in which cartilage slowly degrades. Another problem of knee is meniscus tear. Meniscus act as a weight distributer on joint surfaces and gives stabili...

Meniscal pathologies are among the most common injuries of the femorotibial joint in both human and equine patients. Pathological forces and ensuing injuries of the cranial horn of the equine medial meniscus are considered analogous to those observed in the human posterior medial horn. Biomechanical properties of human menisci are site- and depth- specific. However, the influence of equine meni...

INTRODUCTION The study sought evidence for apoptosis, the expression of MMP-1, MMP-3 and TIMP-2 and their effect on the mechanical and biochemical properties of rabbit fresh knee medial meniscal grafts in a 6-month follow-up. MATERIAL AND METHODS Forty white male New Zealand rabbits were chosen for the study. The medial meniscus was excised from 28 animals and stored under tissue culture cond...

We describe a prospective survival analysis of 63 consecutive meniscal allografts transplanted into 57 patients. The lateral meniscus was transplanted in 34, the medial meniscus in 17, and both menisci (combined) in the same knee in six. For survival analysis we used persistent pain or mechanical damage as clinical criteria of failure. A total of 13 allografts failed (5 lateral, 7 medial, 1 med...

BACKGROUND Limited in vivo kinematic information exists on managing meniscal injury during anterior cruciate ligament reconstruction (ACLR). HYPOTHESIS Isolated anatomic ACLR restores knee kinematics, whereas ACLR in the presence of medial meniscal injury is associated with altered long-term knee kinematics. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS From March 2011 to Decem...

OBJECTIVE This work aimed to assess tibial rotations, meniscal movements, and morphological changes during knee flexion and extension using kinematic magnetic resonance imaging (MRI). METHODS Thirty volunteers with healthy knees were examined using kinematic MRI. The knees were imaged in the transverse plane with flexion and extension angles from 0° to 40° and 40° to 0°, respectively. The tib...

BACKGROUND Knowledge of the impact of viable medial meniscus allograft and autograft transplantation on biochemical and mechanical properties of cartilage is needed to understand the development of joint osteoarthritis. The purpose of this study was to evaluate this relationship 6 months after viable medial meniscal autograft and allograft transplantation. METHODS Twenty rabbits were chosen f...

This guide to ultrasound imaging of the knee describes basic scanning planes and contains corresponding high-resolution images. The patient probe positionings are explained in a simplified step-by-step manner using schematic drawings. standard simple examination technique seems be an appropriate way improve learning curve novice musculoskeletal sonographers. In this manuscript, emphasis is plac...
