Abnormal knee kinematics following reconstruction of the anterior cruciate ligament may exist despite an apparent resolution of tibial laxity and functional benefit. We performed upright, weight-bearing MR scans of both knees in the sagittal plane at different angles of flexion to determine the kinematics of the knee following unilateral reconstruction (n = 12). The uninjured knee acted as a co...

the resistant* of patesa against lateral displacement (le. the stability), was studied tinder a range of conditions in vitro, at a range of knee flexion angles. muscle forces were applied in physiological directions along the separate quadriceps muscles. normal muscle actions with constant tension showed constant patellar stability up to sixty degrees knee flexion, and then a significant increa...

This study explored the link between vitamin D status and frequency of skin infections, inflammation, and injury in college wrestlers during an academic year. METHODS Serum 25-hydroxyvitamin D (25(OH)D) (n = 19), plasma cytokine (TNF-α, IL-6, IL-10) (n = 18) concentrations, and body weight/composition were measured and injury/illness/skin infection data were collected in fall, winter, and spr...

Ten young men sustained an isometric contraction of the knee extensor muscles at 20% of the maximum voluntary contraction (MVC) torque on three separate occasions in a seated posture. Subjects performed an isometric knee extension contraction on a fourth occasion in a supine posture. The time to task failure for the seated posture was similar across sessions (291 +/- 84 s; P > 0.05), and the MV...

Background. Osteoarthritis (OA) ranks fifth in the most disabling conditions. Karate is an unarmed combat sport that uses hands and feet to deliver and block blows. The karate movements, such as high load and frequent flexion and extension of the knee, make the athletes susceptible to knee injuries and progress to knee OA (KOA). Objectives. The study aims to address the prevalence and risk fac...

Purpose: Coronary angiography can cause post-procedural pain, and limited flexibility in the hips and knees may contribute to this discomfort. Patients with restricted hip and knee flexibility may experience increased stress. This study was designed to assess the flexibility of the hip and knee and its relationship with pain experienced after femoral angiography. Methods: This cross-sectional ...
