PURPOSE To examine the influence of two patellofemoral braces on pain response, patellar alignment, and patellofemoral joint contact area in persons with patellofemoral pain. METHODS Fifteen women between the ages of 18 and 45 yr with a diagnosis of patellofemoral pain participated. After the assessment of pain response using a visual analog scale, subjects underwent axial plane magnetic reso...

background: patellofemoral pain (pfp) is a common affliction and complex clinical entity. deficit in neuromotor control of the core may be a remote contributing factor to the development of pfps. comparative evaluation of core and extensor mechanism muscle activation patterns between healthy group and patients involved by patellofemoral pain syndrome(pfps) in a stair stepping task is the aim of...

background:   patellofemoral pain syndrome (pfps) is defined as pain surrounding the patella when sitting with bent knees for prolonged periods of time or when performing activities like ascending or descending stairs, squatting or   athletic activities. patella dislocation is not included in pfps.     purpose:   this review analyzes the evidence based conservative management of pfps.   methods...

There are a variety of operative and non operative modalities that can be used to address patellofemoral pain secondary to arthrosis. Patellofemoral Arthroplasty (PFA) is one of the latest alternatives designed to address the pain caused by severe, isolated osteoarthritis (OA) of the patellofemoral joint (PFJ). in the past, PFA has experienced variable success rates, and as a result many surgeo...

Patellofemoral pain is seen frequently in young and physically active people. The incidence in primary care for the young adult age is about 10 to 12 new cases per 1000 patients per year, while in sports medicine practice, its prevalence may well be around 25%1. The palette of complaints is varied, from mild short-term pain to long-term and load-dependent pain, leading to functional restriction...

abstract introduction: patellofemoral pain syndrome is a common problem in the knee joint, which comprise 20 to 40 percent of knee pain and 10 to 20 percent of subjects admitted in physiotherapy clinics. the aim of this study was to investigate the relationship between navicular drop and tibia torsion in active girl students with and without patellofemoral pain syndrome. materials and methods: ...

abstract   background: the purpose of this study was to evaluate the significance of the q angle with respect to the patella position. we assess the correlation between the q angles (calculated by clinical exam) in different positions and ct indices (with more impression on tttg).   method: atotal number of 68 knee joints of 50 cases entered the study. clinical examination was used to measure q...

conclusions the study findings indicate that short-term exercises had no significant effect on the ratio of vmo to vl muscle fiber angles in patients with pfps. results there were no significant differences in the muscle strength and fiber angle of the vmo, vl oblique and longus muscles after training between the control and experimental groups (p > 0.05). patients and methods thirty-five subje...

PURPOSE Elevated cartilage stress has been identified as a potential mechanism for retropatellar pain; however, there are limited data in the literature to support this mechanism. Females are more likely to develop patellofemoral pain than males, yet the causes of this dimorphism are unclear. We used experimental data and computational modeling to determine whether patients with patellofemoral ...

Powers CM, et al. Br J Sports Med 2017;51:1713–1723. doi:10.1136/bjsports-2017-098717 IntroductIon The aetiology of patellofemoral pain (PFP) is a complex interplay among various anatomical, biomechanical, psychological, social and behavioural influences. Numerous factors associated with PFP have been reported in the literature, but the interaction between these proposed risk factors and the cl...
