Background: One of the most important issues for patients with osteoarthritis is reducing pain and returning them to normal life. In addition to losing weight and improving daily activities, pain management treatments may be needed. One of these treatments is the injection of hyaluronic acid gel into the knee joint, which has been studied in this study. Methods: In this stud...

in order to study the development of knee joint in absence of movement; mouse limb buds were separated from 15 days old embryos and cultured in ham's f-io medium conditioned with 37°c and 5% co2 for 1 to 6 days. the medium was renewed every 24h during incubation. after 6 days, specimens were fixed by buin's fluid, embedded in paraffin wax, serially sectioned and stained with h&e.; the...

UNLABELLED Separate authors have reported that knee extension dominates power production during submaximal cycling (SUB(cyc)) and hip extension is the dominant action during maximal cycling (MAX(cyc)). Changes in joint-specific powers across broad ranges of net cycling powers (P(net)) within one group of cyclists have not been reported. PURPOSE Our purpose was to determine the extent to which...

Background: Spasticity is a common motor impairment in patients with stroke that not only has a negative impact on the patient’s quality of life but also has high economic burdens for society. Recently the application of shock wave therapy has attracted considerable attention as a safe and effective method in treatment of spasticity. The objective of the present study was to investigate the eff...

“Knee Joint Osteoarthritis” is the topic chosen for the first editorial of the second volume of this journal. The aim of this editorial is to discuss this interesting but little analyzed topic in the current literature, in order to explain and help readers to better understand the functional anatomical aspects of knee joints affected by Osteoarthritis (OA). As the knee joint is tri-compartmenta...

A fold that occurs within a joint is referred to as a plica synovialis. Three such plicae are seen with regularity within the human knee joint. These folds are normal structures that represent remnants of mesenchymal tissue and/or septa formed during embryonic development of the knee joint, and can be seen during arthroscopic inspection of the knee joint. Controversy exists within the orthopaed...

BACKGROUND Unilateral below-knee amputees often develop comorbidities that include knee joint disorders (e.g., intact leg knee osteoarthritis), with the mechanisms leading to these comorbidities being poorly understood. Mechanical knee loading of non-amputees has been associated with joint disorders and shown to be influenced by walking speed. However, the relationships between amputee knee loa...

BACKGROUND Although total knee arthroplasty reduces pain and improves function, patients continue to walk with asymmetrical movement patterns, that may affect muscle activation and joint loading patterns. The purpose of this study was to evaluate the specific biomechanical abnormalities that persist after total knee arthroplasty and examine the neuromuscular mechanisms that may contribute to th...

Anterior cruciate ligament injuries are occurring at a higher rate in female athletes compared with their male counterparts. Research in the area of anterior cruciate ligament injury has increasingly focused on the role of joint proprioception and muscle activity in promoting knee joint stability. We measured knee joint laxity, joint kinesthesia, lower extremity balance, the amount of time requ...
