OBJECTIVE The objective of this study was to determine the association between biomechanical and neuromuscular factors of clinically diagnosed mild to moderate knee osteoarthritis (OA) with radiographic severity and pain severity separately. METHOD Three-dimensional gait analysis and electromyography were performed on a group of 40 participants with clinically diagnosed mild to moderate media...

BACKGROUND We were not aware of a well-validated patellofemoral joint-specific scoring system. We performed this study to develop and validate a scoring system (Samsung Medical Center [SMC] patellofemoral scoring system) suitable for the evaluation of patellofemoral joint status. METHODS We recruited 179 individuals consisting of a study group of 123 patients with anterior knee pain but witho...

OBJECTIVE To verify the biologic links between progressive cellular and structural alterations within knee joint components and development of symptomatic chronic pain that are characteristic of osteoarthritis (OA), and to investigate the molecular basis of alterations in nociceptive pathways caused by OA-induced pain. METHODS An animal model of knee joint OA pain was generated by intraarticu...

General description: The Anterior Knee Pain Scale (AKPS) – sometimes called the Kujala Scale (Kujala et al 1993) is a 13-item knee-specific self-report questionnaire. It documents response to six activities thought to be associated specifically with anterior knee pain syndrome (walking, running, jumping, climbing stairs, squatting, and sitting for prolonged periods with knees bent), as well as ...

BACKGROUND Osteoarthritis of the knee involving predominantly the medial tibiofemoral compartment is common in older people, giving rise to pain and loss of function. Many people experience progressive worsening of the disease over time, particularly those with varus malalignment and increased medial knee joint load. Therefore, interventions that can reduce excessive medial knee loading may be ...

BACKGROUND Patellofemoral pain syndrome is a descriptive term applied to patients with nonspecific anterior knee pain, and is the most common knee problem. The pain in most patellofemoral disorders is generalized to the anterior part of the knee. One important concept in patellofemoral joint function is the quadriceps angle (Q-angle). Theoretically, a higher Q-angle increases the lateral pull o...

From a population survey of 2865 subjects, test characteristics of a number of clinical findings relating to knee osteoarthritis were calculated against the standard of radiographic diagnosis. The clinical findings included from the history were age, gender, current pain in the knee, swollen knee, pain in both hands, morning stiffness, osteoarthritis in any joint, pain or stiffness, or both, in...

BACKGROUND Symptomatic knee joint effusion is frequently observed after hip fracture, which may lead to postoperative knee pain during rehabilitation after hip fracture surgery. However, unfortunately, very little has been reported on this phenomenon in the literature. The purpose of the current study was to investigate the relationship between symptomatic knee effusion and postoperative knee p...

background: knee osteoarthritis (oa) is the most common musculoskeletal disease among old individuals which affects ability for sitting on the chair, standing, walking and climbing stairs. our objective was to investigate the short and long-term effects of the most simple and the least expensive exercise protocols in combination to conventional conservative therapy for knee oa.   methods : it w...

Knee joint pain is one of the most common complaints related to the skeletal system encountered by paediatricians. Knee joint pain generally occurs as the result of hypermobility and growing pains, though disorders manifesting as arthritis/arthralgia and orthopaedic problems should be considered in the differential diagnosis. A thorough and careful physical examination and laboratory and radiol...
