BACKGROUND The meniscus plays critical roles in the knee, contributing to load transmission, shock absorption, and joint stability. Little is known about gene expression in meniscal tears, particularly in relation to injury pattern and patient age and sex. The purpose of this study was to test the hypothesis that gene expression in meniscal tears varies depending on patient age and sex and whet...

BACKGROUND The traumatic or degenerative internal derangement of the knee requires certain investigations for the establishment of diagnosis, in addition to clinical history and a thorough physical examination. The use of arthrography and arthroscopy improves the accuracy of the diagnosis. MRI scanning of the knee joint has often been regarded as the noninvasive alternative to diagnostic arthro...

BACKGROUND To identify and characterize the concomitant ligamentous and meniscal injuries in floating knee. METHODS A total of 37 cases of floating knee were enrolled. Arthroscopic or open surgical examination of the knee, Lachman test, posterior drawer's test, and varus and valgus stress tests under anesthesia were carried out to determine the incidence of knee injury. RESULTS Through arth...

OBJECTIVE To investigate the associations between patient sex, age, cause of injury, and frequency of meniscus and articular cartilage lesions seen at the time of the anterior cruciate ligament reconstruction. SETTING University affiliated hospital, Hong Kong. PATIENTS Medical notes and operating records of 672 Chinese patients who had received anterior cruciate ligament reconstruction betw...

Background This study investigated the presence of bursitis in the medial compartment of the knee (pes anserine, semimembranosus-tibial collateral ligament, and medial collateral ligament bursa) in osteoarthritis, chondromalacia patella and medial meniscal tears. Patients and methods Radiological findings of 100 patients undergoing magnetic resonance imaging with a preliminary diagnosis of kn...

OBJECTIVES The purpose of this study was to determine what patient and injury factors are associated with the presence of a meniscus tear in tibial plateau fractures. We also sought to compare functional outcome, pain scores, and range of motion between patient groups with and without meniscal injury. MATERIALS AND METHODS A total of 99 patients with 101 acute tibial plateau fractures were in...

OBJECTIVE The geometry of the tibial plateau has a direct influence on the translation and the screw home biomechanics of the tibiofemoral joint. Little information on the relationship between the tibial slope and meniscal lesions is available. The objective of this retrospective study was to examine the effect of the tibial slope on the medial and lateral meniscus lesions in patients with inta...

MR imaging provides information on soft tissue damage and has been accepted widely for the evaluation of internal knee derangements. Hence the purpose of this study was to evaluate the usefulness of MRI in the early and precise diagnosis and to study the meniscal anatomy, normal variants, types and incidence of injuries in menisci by MRI. Out of 43 patients the males (84%) are commonly affected...

OBJECTIVE To determine clinicians' accuracy and reliability for the clinical diagnosis of unstable meniscus tears in patients with symptomatic osteoarthritis of the knee. DESIGN A prospective cohort study. SETTING A single tertiary care centre. PATIENTS One hundred and fifty-two patients with symptomatic osteoarthritis of the knee refractory to conservative medical treatment were selected...
