The arthroscopic study of knee joint is of outstanding interest in assessment of knee complaints. The present article describes the results of arthroscopic examination of 100 patients (Mean age 29.4 years 82% male) evaluated from 1996 to 1997 in Imam Khomeini hospital of Tehran. Sport injury was the most prevalent cause of referral (40%). The 2 most frequent complaints were knee pain (94%) and ...
Abstract Objective: proprioception is part of the body's sensory system who is responsible for collecting information for the central nervous system to inform about the status of different parts of the body relative to each other Fatigue can causes disorder in the proprioception. In this research, the effect of quadriceps and hamstrings muscles fatigue on knee proprioceptive function in healt...
It is unclear how rotations of the lower limb affect the knee joint compression forces during walking. Increases in the frontal plane knee moment have been reported when walking with internally rotated feet and a decrease when walking with externally rotated feet. The aim of this study was to investigate the knee joint compressive forces during walking with internal, external and normal foot ro...
Objective : To study the correlation between ankle and knee cartilage morphology to test the hypothesis that knee joint cartilage loss in gonarthritis can be estimated retrospectively using quantitative MRI analysis of the knee and ankle and established regression equations; and to test the hypothesis that sex differences in joint surface area are larger in the knee than the ankle, which may ex...
Introduction: Osteoarthritis (OA) is one of the most common joint diseases that is accompanied with cartilage loss and finally leads to joint destruction. The most common joint that is affected in OA is the knee joint. Knee joint OA may lead to significant illness. Methods: The effect of excessive running load on the development of knee OA was investigated in rats. This study aimed to ev...

Muscles are significant contributors to the high joint forces developed in the knee during human walking. Not only do muscles contribute to the knee joint forces by acting to compress the joint, but they also develop joint forces indirectly through their contributions to the ground reaction forces via dynamic coupling. Thus, muscles can have significant contributions to forces at joints they do...
Background and Aim: Fatigue and abnormalities in the lower extremities, such as the pronated foot, can adversely affect the biomechanics of human movements such as running, leading to a lack of muscle contraction and unstable symptoms in the joints of the lower extremities (knees). Therefore, the main purpose of this study was to investigate the effect of exhaustive protocol on knee muscle co-c...
For a proper functional restoration of the knee following knee arthroplasty, a comprehensive understanding of bony and soft tissue structures and their effects on biomechanics of the individual patient is essential. If the joint surface is altered due to arthritis, fracture or alloplastic knee surface replacement, knee biomechanics may be disturbed [Sharma2012, Delport2012]. Otherwise, if the l...
In the single-joint torque exertion task, which has been widely used to control muscle activity, only the relevant joint torque is specified. However, the neglect of the neighboring joint could make the procedure unreliable, considering our previous result that even monoarticular muscle activity level is indefinite without specifying the adjacent joint torque. Here we examined the amount of hip...
