Prevalence and mechanisms of anterior cruciate ligament tears in military personnel: A cross-sectional study in Iran.

Background: Anterior cruciate ligament (ACL) tear is common in military setting; such an injury increase institutional costs and workforce strain, however, few studies have investigated the mechanism and associated factors of ACL tear specifically in a military setting. The aim of this study was to investigate the prevalence and mechanisms of ACL tears in military personnel at a military referral hospital in Iran.

Material And Methods: This cross-sectional study examined 402 military personnel who presented with knee complaints at a single referral Iranian military hospital.

Treatment of Femoral Head Osteonecrosis (Stages 2B, 3 Ficat) Through Open Direct Core Decompression by Allograft Impaction and Light Bulb Technique.

Background: Femoral head avascular necrosis is the cause of paralyzing status of youth population. Initial diagnosis is the main element in treating the disease. Bone grafting and core decompression are the approved cures at the early steps of the disease.

A theory of planned behavior-based intervention to improve quality of life in patients with knee/hip osteoarthritis: a randomized controlled trial.

Osteoarthritis (OA) is a common chronic disorder among elderly people that affects joints such as the knee and hip in particular. The objective of the current study was to examine the efficacy of an intervention based on a theory of planned behavior (TPB) in improving health-related quality of life in middle-age and older adults with this condition. One hundred twenty patients diagnosed with knee/hip OA were recruited from a general hospital.

Acute Cardiovascular and Hemodynamic Responses to Low Intensity Eccentric Resistance Exercise with Blood Flow Restriction.

Background: Recently it has been suggested that low intensity (LI) resistance exercise (RE) alone or in combination with blood flow restriction (BFR) can be applied for cardiovascular function improvement or rehabilitation.

Objectives: The aim of the present study was to investigate the acute effects of LI eccentric RE with and without BFR on heart rate (HR), rate pressure product (RPP), blood pressure (BP) parameters [systolic, diastolic, and mean arterial pressure (MAP)], oxygen saturation (SpO2) and rate of perceived exertion (RPE).

Methods: In a semi-experimental study 16 young adults (26.

Comparison of Indirect MR Arthrography With Conventional MRI in the Diagnosis of Knee Pathologies in Patients With Knee Pain.

Background: Knee pain is a common problem in the general population. In order to determine the extent of the injury and the appropriate treatment, MRI provides the most accurate imaging method. This may be done through conventional MRI techniques or by injecting a contrast material (MR arthrography).

Studying the Relation Between Medial Tibial Stress Syndrome and Anatomic and Anthropometric Characteristics of Military Male Personnel.

Background: Medial Tibial Stress Syndrome (MTSS) is common among military recruits and to our knowledge; the factors that might put the military recruits at higher risk of incidence of MTSS are not well known.

Objectives: This study was done to investigate the association between some anthropometric and anatomical factors and the prevalence of MTSS among military recruits.

Patients And Methods: One hundred and eighty one randomly selected military recruits were included in this cross sectional study.

Association of Soccer and Genu Varum in Adolescents.

Background: Genu varum is a physical deformity marked by bowing of the leg. One of the risk factors of this musculoskeletal alignment is stress on the knee joint such as with exercise.

Objectives: Since the evaluation of genu varum has not been widely studies, this study was conducted to examine the association between genu varum and playing soccer.

Psychometric examination of the Persian version of Osteoarthritis Knee and Hip Quality of Life questionnaire.

Aim: Osteoarthritis is a serious and prevalent health problem that creates considerable disability when it involves the knee or hip joints. The aim of the study was to adapt and validate the Osteoarthritis Knee and Hip Quality of Life (OAKHQOL) questionnaire for use in a Persian-speaking population.

Methods: A total of 434 patients were recruited.

Effects of preoperative use of oral dextromethorphan on postoperative need for analgesics in patients with knee arthroscopy.

Background: Studies have shown that N-methyl-D-aspartate receptor (NMIDA) plays an essential role in postoperative pain. It seems that use of NMDA receptor antagonists such as Dextromethorphan intensifies the analgesic effects of opioids.

Objectives: In this study, we evaluated the effect of preoperative administration of Dextromethorphan on postoperative pain reduction.

Knee Flexion Strength Before and After ACL Reconstruction Using Hamstring Tendon Autografts.

Background: Anterior cruciate ligament (ACL) injury is the most common sports injury in both athletes and nonathletes; it can cause disability if not treated correctly. In cases with minor injuries, conservative treatments suffice. But, in cases with ACL tear, surgery by different methods and autografts are indicated.

Concomitant ligamentous and meniscal knee injuries in femoral shaft fracture.

Background: Concomitant knee injury is a common finding in femoral fractures but can be easily missed during early management of the initial trauma. Degrees of damage to the articular structures vary considerably; from only a mild effusion to complete ligamentous and meniscal tears. Since previous reports were mostly from developed societies, this study was designed to look into characteristics of associated knee injury in a sample from Iran, to represent a developing country perspective.
