OBJECTIVE: We aimed to (i) determine reference values for trochlear morphology and patellofemoral (PF) alignment in adults without MRI-defined PF full thickness cartilage damage or knee pain; and (ii) evaluate dose-response patterns for these measures with prevalent MRI-defined PF structural damage and/or knee pain. DESIGN: The Framingham Community Cohort is a population-based sample of ambulatory adults aged ≥50 years. We evaluated six morphology and alignment measures using MRI (n=985), and reported reference values (mean ± 2SD) in a subsample without MRI-defined PF full thickness cartilage damage or knee pain (n=563)...

BACKGROUND: The available comparative studies of computer navigation-assisted and conventional knee arthroplasties have short-term follow-up periods. Therefore, the clinical benefits after long-term follow-up are not clear. The purposes of the current long-term study were to compare clinical outcomes, alignment of the knee components, prevalence of aseptic loosening of the components, implant survival, and complications of total knee arthroplasties performed with and without computer navigation...

This study aimed to 1) investigate the incidence and characteristics of injuries in emerging rugby league players; and 2) explore the differences in injury incidence and characteristics between the various sub-elite competitions. An NRL emerging player development squad (n = 34) was observed from the beginning of pre-season until the finish of competition. Time-loss injury was defined as any physical pain or impairment sustained that resulted in players missing a match. Injuries were categorised according to circumstance, incidence, characteristics, playing position and competition level...

OBJECTIVE: Hemophilic arthropathy is associated with pronounced vascular joint remodeling. Also, compared to the general population, PWH have a higher prevalence of hypertension not explained by usual risk factors. Since vascular remodeling in various vascular beds is a hallmark of hypertension, we hypothesized that vascular joint remodeling is associated with elevated blood pressures and hypertension. METHODS: Elbows, knees and ankles of 28 adult PWH were evaluated for vascular abnormalities with MSKUS/PD, as well as for radiographic and clinical status and pain...

Previous research has reported a prevalence of running related injuries in 25.9% to 72% of all runners. A greater hip internal rotation and adduction during the stance phase in running has been associated with many running related injuries, such as patellofemoral pain. Researchers in the USA designed a treatment device 'the Powers™ strap' to facilitate an external rotation of the femur and to thereby control abnormal hip and knee motion during leisure and sport activities. However, to date no literature exists to demonstrate whether the Powers™ strap is able to reduce hip internal rotation during running...

Isolated patellofemoral osteoarthritis is relatively prevalent, with the lateral facet of the patella being the most commonly affected portion. This pathology can be a result of a patellar maltracking syndrome, patella instability, or idiopathic degenerative changes. A thorough diagnostic work-up with a physical examination and imaging studies are mandatory for a proper diagnosis and to rule out other causes of patellofemoral knee pain. These patients are often treated nonoperatively with exercises for patella mobility, intra-articular injections, braces, patellar tracking, quadriceps balance and strength, and activity modification...

REVIEW
Chaitu Malempati, Cale A Jacobs, Christian Lattermann
Patients with early osteoarthritis (OA) have been reported to have inferior outcomes with an increased prevalence of early failure after cartilage procedures. The underlying reasons for this failure are likely multifactorial, including a chronic synovial and chondrogenic process, which is confounded by persistent muscle weakness and altered pain processing for those with increased preoperative symptom duration. Pain, radiographic changes, patient-reported outcomes, and macroscopic changes on arthroscopic evaluation or MRI can assist clinicians in identifying the early OA knee to both aid in clinical decision making and create realistic postoperative expectations for patients...

BACKGROUND: The aims of this study were to identify the prevalence and causes of dissatisfaction in a cohort of private practice patients, and to compare the psychological characteristics of dissatisfied patients to matched, satisfied controls. METHODS: Unilateral TKR patients were evaluated to identify those dissatisfied with their TKR. Dissatisfied and satisfied patients were matched in terms of age, gender, follow-up duration and body mass index (BMI). Psychological evaluation was performed using the Pain Catastrophizing Scale (PCS), Depression, Anxiety and Stress Scale (DASS) and the Multidimensional Health Locus of Control (MHLC) scale...

A 29-year-old man with a previous football injury to his left knee presented with pain of the same knee. The patient twisted it as he was turning a corner quickly while going up the stairs, leading to internal rotation of his femur on his tibia with his knee in flexion. MR imaging revealed a bucket-handle tear of the medial meniscus, as well as a complete tear of the anterior cruciate ligament. However, image interpretation was complicated by the presence of a medial oblique meniscomeniscal ligament, a rare normal variant among intermeniscal ligaments of the knee...

Tal Frenkel Rutenberg, Michael Drexler
The prevalence of overweight and obesity in the western world is growing, and with it there is a growing number of patients with osteoarthritis, a condition that leads to pain and disability. The association between body weight and osteoarthritis is mediated by both mechanical and humeral factors such as growth factors, hormones and mediators of the immune system. This review will present the mechanisms which lead to osteoarthritis, and will discuss available treatments which are suitable for the overweight and obese population, along with promising emerging new treatments...

AIM: The purpose of the present study was to investigate whether sarcopenia was associated with future falls in the general Japanese older population. METHODS: This study was a 2-year prospective observational study. Participants were recruited from individuals who had an annual town-sponsored medical check-up and had not received nursing care. The inclusion criteria for participants in our study were: (i) agreement to participate; (ii) living independently; and (iii) the ability to walk to where the survey was carried out and to provide self-reported data...

AIM: To explore pain screening in CPUP, a follow-up surveillance programme for people with cerebral palsy (CP), specifically to describe reported pain prevalence, localizations, patterns of distribution; to compare with studies using psychometrically sound assessment instruments; and to assess agreement between pain documented in CPUP and medical records. METHOD: Registry study of a population with CP, born 1993 to 2008, living in Skåne, Sweden in 2013. Descriptive data, cross-tabulations, and chi-square tests to characterize and compare the study groups...

Background: Musculoskeletal pain is highly prevalent and limits mobility in older adults. A potential mechanism by which pain affects mobility could be through its negative impact on the brain. We examined whether structural integrity of cerebral gray and white matter (WM) mediated the relationship between pain and mobility in community-dwelling older adults. Methods: Musculoskeletal pain, gait speed, and neuroimaging data were obtained concurrently from the Health ABC study (mean age = 83/56% female, n = 212)...

BACKGROUND: Physical activity (PA) typically decreases with aging, especially of moderate to vigorous level, and this change affects health outcomes of older adults. Age-related decline is not evenly distributed across elderly population and is attributed to psychosocial, physical, and environmental determinants. METHODS: We selected a sample of 1000 elderly people from urban parts of Shiraz in Southern Iran with a two-stage random sampling procedure. Self-reported PA data and correlates of moderate to vigorous activity were collected by interview with the respondents from selected households...

BACKGROUND: As an important outcome measure among rheumatoid arthritis (RA) patients, functional disability may contribute to unemployment, loss of work productivity, and impaired quality of life. However, little is known about the risk factors of functional disability in Chinese RA patients. This study aimed (1) to examine the prevalence of functional disability in Chinese RA patients; (2) to explore factors associated with the health assessment questionnaire-disability index (HAQ-DI)...
