purpose : to investigate tear film status after phacoemulsification surgery with temporal and supratemporal clear corneal incision in a cohort of patients with senile cataract methods : we enrolled sixty eight eyes of 68 patients with senile cataract requiring phacoemulsification in a prospective, cohort study. all patients undergone basic tear secretion test (btst), tear meniscus height (tmh),...

BACKGROUND The management of meniscus tears identified at the time of primary anterior cruciate ligament (ACL) reconstruction is highly variable and includes repair, meniscectomy, and nontreatment. HYPOTHESIS/PURPOSE The purpose of this study was to determine the reoperation rate for meniscus tears left untreated at the time of ACL reconstruction with a minimum follow-up of 6 years. The hypot...

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...

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 ...

Magnetic resonance (MR) imaging is currently the modality of choice for detecting meniscal injuries and planning subsequent treatment. A thorough understanding of the imaging protocols, normal meniscal anatomy, surrounding anatomic structures, and anatomic variants and pitfalls is critical to ensure diagnostic accuracy and prevent unnecessary surgery. High-spatial-resolution imaging of the meni...

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...

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...
