Introduction: It has been approved that in most tissues NO production increases during acute inflammation and Angiotensin II has a role in production of reactive oxygen species (ROS). As regulation of joint blood flow (JBF) is important in this situation, this study was performed to investigate the interaction of local Ang II and ROS production and the modulatory role of NO on regulation of JBF...

primary knee osteoarthritis (oa) is one of the degenerative diseases that destroy auricular cartilage within knee joint and cause pain, varies deformity, decrease knee function. total knee arthroplasty (tka) is an effective intervention in order to relieve pain, improve function and qol (quality of life) in patients with severe osteoarthritis of the knees that have different degrees of varus de...

The knee joint is the one of the most common locations for congenital and developmental musculoskeletal abnormalities. Initial imaging of the knee joint should always begin with conventional radiographs. However, evaluation of the bone marrow, cartilaginous, ligamentous, and other soft-tissue components of the knee joint are better characterized with magnetic resonance imaging (MRI). We present...

BACKGROUND Many studies have been published on the development of the human knee joint, but different investigators disagree on its morphogenetic time table. Most discrepancies center on the cavitation of the knee joint and the participation of the superior tibiofibular joint in the joint knee system. METHODS We summarize our observations of the development of the knee joint in 50 serially se...

BACKGROUND Stair ascent is a very demanding task for transfemoral amputees (TFAs). The purpose of this study was to investigate the lower extremity joint kinematics of TFAs who can climb stairs using a step-over-step gait pattern without an active artificial prosthetic knee joint or handrail use. CASE DESCRIPTION AND METHODS Case series. Participants were two traumatic TFAs and 10 control par...

[Purpose] The purpose of this study was to ascertain the kinematic characteristics on a horizontal plane, including knee joint rotation, when walking with a tandem gait on a sine wave walkway. [Subjects and Methods] Eighteen healthy adults were enrolled as subjects in this study. They walked with a tandem gait on a sine wave walkway. A three-dimensional motion analysis system was used to record...

Anterior knee pain and/or radiological evidence of degeneration of the patellofemoral joint are considered to be contraindications to unicompartmental knee replacement. The aim of this study was to determine whether this is the case. Between January 2000 and September 2003, in 100 knees (91 patients) in which Oxford unicompartmental knee replacements were undertaken for anteromedial osteoarthri...

  Background: Osteoarthritis is a disabling musculoskeletal disease with no definite treatment. This study compared the effect of Platelet-rich plasma (PRP) and Transcutaneous Electrical Nerve Stimulation (TENS) plus exercise in the treatment of patients with knee joint osteoarthritis.   Methods : 54 eligible patients with knee osteoarthritis were randomly allocated into two groups. (IRCT201211...
