Background: The ultimate goal of the treatment of infectious knee arthritis is to protect the articular cartilage fromadverse effects of infection. Treatment, however, is not always hundred percent successful and has a 12% failurerate. Persistent infection is more likely to happen in elderly patients and those with underlying joint diseases,particularly osteoarthritis. Eradica...

knee surgery. the purpose of this study was to assess the analgesic effects of intra-articular injection of a dexmedetomidine following knee arthroscopy. methods:   forty six patients schadualed for arthroscopic knee surgery under general anaesthesia, were randomly devided into two groups. intervention group received 1μg/kg dexmedetomidine (d) and isotonic saline. control group received 25ml is...

hysteretic dampers as the most practical passive control methods have improved the seismic performance of steel structures through energy dissipation induced by large inelastic deformations. among them in this paper, kbf (knee braced frames), a special form of braced frames having a diagonal brace connected to a knee element instead of beam-column joint, is investigated. in such systems, the kn...

Postoperative flexion is an important factor in the outcome of total knee arthroplasty. Although normal activities of daily living require a minimum of 105° to 110° of flexion, patients from non-Western cultures often engage in activities such as kneeling and squatting that require higher flexion. The desire to achieve greater flexion serves as the driving force for prosthetic modifications, in...

OBJECTIVE To estimate the costs and health outcomes of C-Leg and non-microprocessor-controlled (NMC) knees using a decision-analytic model. DESIGN Data on costs, rates and duration of problems, knee survival, and health-related quality of life were obtained from interviews with patients and prosthetists with experience of both C-Leg and NMC knees. Interview data were assessed in a decision-an...

Iliotibial band syndrome (ITBS) is a common overuse knee injury that is twice as likely to afflict women compared to men. Lower extremity and trunk biomechanics during running, as well as hip abductor strength and iliotibial band flexibility, are factors believed to be associated with ITBS. The purpose of this cross-sectional study was to determine if differences in lower extremity and trunk bi...

Experiments were carried out on anesthetized adult New Zealand rabbits. Acute joint inflammation was achieved by intra-articular injection of 2% carrageenan. Radiolabelled microspheres were used to measure the effect of acute inflammation on blood flow in the knee joint and establish whether neural influences on blood vessel caliber were affected. Surgical exposure of the posterior joint "capsu...
