Patellofemoral joint arthritis is a common condition which can be extremely debilitating. Although it is a common condition, the treatment of isolated patellofemoral arthritis varies and remains controversial. The objective of this review is to provide an overview of the current understanding of patellofemoral arthritis and various different surgical options, indications, and their respective o...

The Patellofemoral pain syndrome (PFPS) is the most common knee complaint seen in adolescent and young adults. Pain in the knee is usually anterior, not well localized, and diffuse. The purpose of this study was to analyze which of the presumed physical examination signs which can be present in an asymptomatic population are a consequence of intrinsic risk factors for this disease. 263 patients...

BACKGROUND Patellofemoral pain is a very common musculoskeletal condition. In the last years, evidence regarding this disease increased exponentially. Although widely investigated, this problem still frustrates patients and clinicians for having an unfavorable prognosis. Some gaps still exist in the understanding and managing of patellofemoral pain. Numerous cross-sectional association studies ...

The medial patellofemoral ligament has been recognized as the structure primarily responsible for preventing patellar subluxation or dislocation.1-3 Anatomic dissection studies identified the medial patellofemoral ligament as a band of tissue connecting the femoral medial epicondyle to the proximal part of the medial edge of the patella (Figure 1).1-6 Imaging studies7-11 and surgical exploratio...

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...

The objective of this study was to determine the effects of tibial rotation on in situ strain in the peripatellar retinaculum and patellofemoral contact pressures and areas. Patellofemoral joint biomechanics demonstrate a strong correlation with the etiology of patellofemoral disorders, such as chondromalacia, and are significantly influenced by tibial rotation. Six human cadaveric knees were u...

BACKGROUND The intent of the present study was to determine the effectiveness of massage therapy in the rehabilitation of post-anterior cruciate ligament reconstruction patellofemoral pain syndrome. The primary complications following surgical repair of the anterior cruciate ligament-classified as patellofemoral pain syndrome-are hamstring flexion contracture and quadriceps weakness, leading to...

The medial soft-tissue restraints of the patella, specifically the medial patellofemoral ligament and the vastus medialis obliquus muscle, are critical to patellofemoral joint stability. A reliable and inexpensive imaging technique would be clinically useful especially after acute patellar dislocation. The medial patellofemoral ligament and the vastus medialis obliquus muscle were identified in...
