Patellofemoral pain is common in both athletic and nonathletic individuals. It is observed in 15%–33% of the young active group and approximately in 21%–45% in adolescence. Among athletes, men tend to present with more patellofemoral injuries than women. In the nonathletic population, women and young individuals more commonly present with patellar disorders. Many static and dynamic internal der...

The etiology of patellofemoral pain is likely related to pathological femoral shape and soft-tissue restraints imbalance. These factors may result in various maltracking patterns in patients with patellofemoral pain. Thus, we hypothesized that femoral shape influences patellofemoral kinematics, but that this influence differs between kinematically unique subgroups of patients with patellofemora...

Myhill-Nerode Theorem is regarded as a basic theorem in the theories of languages and automata and is used to prove the equivalence between automata and their languages. The significance of this theorem has stimulated researchers to develop that on different automata thus leading to optimizing computational models. In this article, we aim at developing the concept of congruence in general fuzzy...

Patellofemoral ağrı sendromu (PFAS), fleksiyon ve ekstansiyon sırasında dize aşırı yüklenme nedeniyle çömelle, koşma, tırmanma merdiven inip çıkma gibi ekleme yük binen aktiviteler ki ön diz ağrısı olarak tanımlanır. Klinik teşhiste altın bir standart yoktur. Olabilecek diğer problemler elimine edilerek tanı konulur. Konservatif tedavide nonsteroid anti-inflamatuvar ilaçlar, dizlik, bantlama, g...

We describe the radiographic measurement of the angle of tilt of the patella and relate it to malalignment of the extensor mechanism. The tilt angle is defined as the angle subtended by a line joining the medial and lateral edges of the patella and the horizontal. The radiograph (Merchant type) is taken with the foot pointing up, the lower edge of the film parallel to the ground, and the knee a...

Accurate rotation of the femoral component in total knee arthroplasty is important for normal patella tracking, symmetrical patellofemoral joint contact, neutral varus-valgus positioning in flexion, correct rotational alignment of the tibia in extension and the avoidance of anterior femoral notching . Internal rotation of the femoral component causes a shift into valgus alignment with flexion a...

purpose there is a decrease in quadriceps muscle strength in subjects with patellofemoral pain syndrome. various types of strengthening exercises of the quadriceps are done as part of its management, but the effect of isotonic eccentric quadriceps muscle exercises on patellofemoral pain syndrome has not been studied. hence the aim of this exploratory pilot study was to evaluate the effect of ec...

Clinical analyses have shown that injuries and pain linked specifically to fencing training/competition were prevalent in 92.8% of fencers. Patellofemoral pain is the most common chronic injury in athletic populations and females are considered to be more susceptible to this pathology. This study aimed to examine gender differences in patellofemoral contact forces during the fencing lunge. Pate...

Although wearing high-heeled shoes has long been considered a risk factor for the development for patellofemoral pain (PFP) in women, patellofemoral joint kinetics during high-heeled gait has not been examined. The purpose of this study was to determine if heel height increases patellofemoral joint loading during walking. Eleven healthy women (mean age 25.0±3.1 yrs) participated. Lower extremit...
