A 20-year-old National Serviceman presented with left knee pain and swelling after training for his physical fitness test. Lateral knee radiography and magnetic resonance (MR) imaging showed patellar tendon-lateral femoral condyle friction syndrome (PT-LFCFS), on a background of patella alta and patellar malalignment. The patient was treated non-operatively with a course of physiotherapy and given advice on rest and activity modification. PT-LFCFS is a less well-recognised but important cause of anterior knee pain and represents an entity in a spectrum of disorders related to patellofemoral instability...

Running is a common form of exercise but predisposes athletes to several running-related injuries. Most running injuries are due to overuse and respond to conservative treatment. Tendinopathies in the patellar, Achilles, and hamstring tendons are common, and are primarily treated with eccentric exercise. Iliotibial band syndrome and patellofemoral pain syndrome are less common than patellar tendinopathy and are treated by strengthening exercises for the core and legs in addition to flexibility exercises. Acute hamstring strains and medial tibial stress syndrome require a period of relative rest, followed by stretching and graded return to activity...

CONTEXT: Tightness or lack of flexibility of flexibility of several muscles of the thigh has been associated with patellofemoral-join pain. A tight iliotibial band can lead to laterally located patella and an abnormal patellar tracking pattern. Diacutaneous fibrolysis is commonly used to reduce muscle tightness, but no studies have evaluated the effects of this technique in the treatment of patellofemoral pain syndrome patients. OBJECTIVE: To assess the effect of diacutaneous fibrolysis on patellar position in patients with patellofemoral pain syndrome...

[Purpose] Neuromuscular activity has been evaluated in patellofemoral pain syndrome but movement velocity has not been considered. The aim was to determine differences in onset latency of hip and knee muscles between individuals with and without patellofemoral pain syndrome during a single leg squat, and whether any differences are dependent on movement velocity. [Subjects and Methods] Twenty-four females with patellofemoral pain syndrome and 24 healthy females participated. Onset latency of gluteus maximus, anterior and posterior gluteus medius, rectus femoris, vastus medialis, vastus lateralis and biceps femoris during a single leg squat at high and low velocity were evaluated...

Patellofemoral syndrome (PFS) is a common etiology of anterior knee pain, particularly amongst young female athletes. Despite recent advancements in the resolution of magnetic resonance imaging (MRI), there still remains a paucity of literature that has investigated the MRI findings associated with PFS. This pictorial essay will describe our institutions experience with cases of PFS and review what we believe to be a constellation of findings associated with this diagnostic entity. This review will also describe common pitfalls encountered during the diagnosis of PFS...

Patellofemoral pain syndrome (PFPS) is one of the most common causes of knee pain and is present in females disproportionately more relative to males. PFPS causes tend to be multifactorial in nature and are described in this review. From a review of the current literature, it is clear that there needs to be further research on PFPS in order to better understand the complex etiology of this disorder in both males and females. It is known that females with patellofemoral pain syndrome demonstrate a decrease in abduction, external rotation and extension strength of the affected side compared with healthy patients...

Patellofemoral pain syndrome (PFPS) is one of the most common diseases that cause pain in the knee joint. At present, there is no specific diagnostic measure. The diagnosis of patellofemoral pain syndrome may be considered when imaging is performed without cartilage, ligament and soft tissue injuries. The etiology includes abnormalities of the patellar motion caused by various anatomical abnormalities, such as abnormal patellar position, increased Q angle, and excessive valgus foot. Dysfunction of the lower extremity muscles such as the imbalance of the four biceps and the dysfunction of the gluteal muscles also play an important role in the development of patellofemoral pain syndrome...

We discuss the pediatric patella, with an emphasis on diagnostic imaging. Topics include normal patellar development, anatomical variants and their physiologic significance, genetic syndromes that alter the appearance of the patella, physiology of patellar tracking and stability, patellofemoral instability, and injury patterns and classification. Recognition of appropriate development on imaging prevents diagnostic error and unnecessary evaluation. Knowledge of the pertinent features of syndromes associated with morphological patellar abnormalities can aid in generating a succinct and relevant differential diagnosis...

INTRODUCTION: Up to 20% of total knee arthroplasty patients remain unsatisfied post-surgery, and a large proportion of them report anterior knee pain. This study aims to verify whether patients who experience anterior knee pain after total knee arthroplasty (TKA) will exhibit kinematic characteristics similar to those associated with patellofemoral syndrome, including in the frontal and transverse planes. MATERIALS AND METHODS: Using four different assessment methods [radiological, patient-reported outcome, musculoskeletal assessment with functional performance testing, and a 3D kinematic assessment during gait], the clinical and 3D knee kinematic profiles of three groups were compared: a painful and an asymptomatic TKA group and a healthy control group...
