BACKGROUND The menisci are integral to normal knee function. The purpose of this study was to measure the contact pressures transmitted to the medial tibial plateau under physiological loads as a function of the percentage of the meniscus involved by the radial tear or repair. Our hypotheses were that (1) there is a threshold size of radial tears above which contact mechanics are adversely affe...

Numerous studies have shown the biomechanical properties of the meniscus can be restored with repair. The aim of this study is to evaluate if partial undersurface tears of the medial meniscus encountered at the time of arthroscopy have any biomechanical impact on the contact area and peak pressure of the knee. Methods: Nine unmatched cadaveric knees were harvested. The knees were inspected for ...

PURPOSE To describe corneal sensitivity changes caused by different incision methods-manual small-incision cataract surgery (manual SICS) and phacoemulsification-and their influence on tear film quantity and quality. METHODS This was a prospective observational study conducted in 30 subjects undergoing manual SICS or phacoemulsification. Corneal sensitivity was assessed before and 1, 7, and 1...

Marginal fractures of the medial tibial plateau have been reported in the literature as a secondary type of Segond fracture. Some reports described this entity in the setting of combined injuries such as root avulsions of the medial meniscus, complete disruption of the posterior cruciate ligament (PCL), partial tear of the anterior cruciate ligament (ACL), and tears of the medial meniscus and m...

Extensive studies have explored the dynamics of the ocular surface fluid, though theoretical investigations are typically limited to the use of the lubrication approximation, which is not guaranteed to be uniformly valid a-priori throughout the tear meniscus. However, resolving tear film behaviour within the meniscus and especially its apices is required to characterise the flow dynamics where ...

oblique tear of the meniscus with an attached fragment displaced away from the donor meniscus (1,2). In order that surgical intervention is appropriate, it is important to visualize the displaced meniscal fragment as well as determine the type of meniscal injury(1,3). Several magnetic resonance imaging (MRI) findings have been used for the diagnosis of bucket-handle tears: (1) the double poster...

INTRODUCTION A discoid medial meniscus is a rare pathology of the knee joint, and is even rarer when it presents bilaterally with clinical symptoms. CASE PRESENTATION We present the case of a 38-year-old female with symptomatic bilateral discoid medial meniscus. Magnetic Resonance Imaging (MRI) showed complete discoid meniscus in one knee and incomplete, on the other side. The MRI findings we...

PURPOSE To evaluate the classification of punctal stenosis based on the shape of the external punctum, clinical characteristics and histopathologic features. METHODS Patients who experienced tearing and were diagnosed with punctal stenosis were evaluated in this study. Punctal stenosis was classified according to the shape of the lower external punctum, which included membranous type, slit ty...
