A 19-year-old male professional Taekwondo athlete presented with a 2-year history of pain-free snapping of his right knee. He reported that his right knee joint gave way during games and training and that he could induce pain-free snapping between the proximal-to-fibular head and the lateral knee joint line. None of these physical findings suggested a meniscal pathology or ligamentous instabili...
Tear hyperosmolarity is thought to play a key role in the mechanism of dry eye, a common symptomatic condition accompanied by visual disturbance, tear film instability, inflammation and damage to the ocular surface. We have constructed a model for the mass and solute balance of the tears, with parameter estimation based on extensive data from the literature which permits the influence of tear e...
Background: Meniscal root tears cause biomechanical changes comparable to a total meniscectomy. The resultant compromise in hoop stress, leads decreased tibiofemoral contact area and increased pressure. This will lead early arthritis. meniscus tear causes more detrimental people with varus alignment of the lower limb. increases chances progression arthritis, causing joint pain functional limita...
Meniscal tears and meniscal instability are rare complications of a discoid lateral meniscus in a very young child. We report a case of a 32-month-old male who presented with a limp and limited extension of his right knee. Magnetic resonance and sonographic images demonstrated a discoid meniscus with a posterior horn tear and unstable anterior horn, confirmed by arthroscopy. The patient was tre...
BACKGROUND Discoid lateral meniscus (DLM) is relatively common in East Asia..Symptomatic discoid lateral meniscus (SDLM) is an important indication for knee arthroscopic surgery. However, studies investigating SDLM are rare. The purpose of this study was to evaluate the clinical characteristics and intra-articular variants of SDLM in a Chinese population. METHODS We retrospectively reviewed a...
BACKGROUND Consistency of arthroscopic evaluation and documentation in meniscal tears between investigators is essential to the validity of multicenter studies. A group of experts developed a classification of meniscal tears that may be used internationally. HYPOTHESIS The International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification of meniscal te...
PURPOSE To investigate tear meniscus volumes during short-term lens wear by soft contact lens (SCL) wearers with dryness symptoms. METHODS Three groups of 20 subjects were recruited. Group 1 consisted of SCL wearers with self-reported dryness. Group 2 consisted of asymptomatic wearers. Group 3 was composed of asymptomatic non-lens wearers. Contact lenses were fitted on each eye, and both uppe...
BACKGROUND Recent studies have demonstrated that pterygium has a close relationship with dry eye disease. This study is to determine abnormalities in meibomian gland and tear function in patients with pterygium and to assess the relationship between the variables. MATERIALS AND METHODS Forty eyes from forty patients with primary nasal pterygium and forty eyes from forty volunteers without ocu...
OBJECTIVE Successful repair of defects in the avascular zone of meniscus remains a challenge in orthopedics. This proof of concept study aimed to investigate a guided tissue regeneration approach for treatment of tears in meniscus avascular zone in a goat model. DESIGN Full-depth longitudinal tear was created in the avascular zone of the meniscus and sutured. In the two treatment groups, porc...
