This study aimed to compare the concentric and eccentric activity and the temporal order of peak activity of the hip and knee muscles between women with patellofemoral pain (PFP) and healthy women during the single leg triple hop test (SLTHT). Electromyographic (EMG) and Kinematic data were collected from 14 healthy women (CG) and 14 women diagnosed with PFP (PFG) during a single session of the single leg triple hop test. Integral surface electromyography (iEMG) data of the hip and knee muscles in eccentric and concentric phases and the length of time that each muscle needed to reach the maximal peak of muscle activity were calculated...

BACKGROUND: The etiology of patellofemoral pain (PFP) is thought to be the result of increased patellofemoral joint (PFJ) load and aberrant lower extremity mechanics, including altered vertical ground reaction forces (VGRF). However, few studies have investigated the association between an increase in pain and VGRF loading rates in the context of PFP. Thus, this study aimed to investigate the immediate effects of PFJ loading on pain and VGRF loading rate, and to see if there is a link between modification of both pain and VGRF loading rate during stair negotiation...

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...

BACKGROUND: Patellofemoral pain (PFP) has been linked to increased patellofemoral joint stress as a result of excessive hip internal rotation. Lower hip strength and/or excessive rearfoot eversion have been used to explain such altered movement pattern; however, it is unknown which one is the best predictor of excessive hip internal rotation. RESEARCH QUESTION: To investigate if peak rearfoot eversion and/or peak concentric hip abductor strength can predict peak hip internal rotation during stair ascent in women with PFP...

Reconstruction of the medial patellofemoral ligament has gained in popularity as a surgical technique to reconcile recurrent lateral patellar instability. This technique has shown success in a variety of settings including with concomitant osseous abnormalities. Despite the general good to excellent results with medial patellofemoral ligament reconstruction, a number of technical errors are still commonly made and may result in decreased range of motion, pain, chondrosis, and arthrofibrosis. In a recent study, the importance of knee flexion angle during final fixation of the graft is emphasized...

A biplanar osteotomy aiming to anteromedialize the anterior tibial tuberosity to realign the patellofemoral joint described by Prof. Fulkerson is one of the classical operations to address many pathologies of the patellofemoral joint. The procedure is evidence-based and effective for the management of patellofemoral pain and osteoarthritis, confirming that the original ideas and concepts are still valid, and still stand strong. In high-demand patients, the Fulkerson osteotomy offers good opportunities of success in terms of return to sport...

[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...

Background: Patellofemoral pain (PFP) is often reported as a diffuse pain at the front of the knee during knee-loading activities. A patient's description of pain location and distribution is commonly drawn on paper by clinicians, which is difficult to quantify, report and compare within and between patients. One way of overcoming these potential limitations is to have the patient draw their pain regions using digital platforms, such as personal computer tablets. Objective: To assess the validity of using computer tablets to acquire a patient's knee pain drawings as compared to paper-based records in patients with PFP...

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...

INTRODUCTION: Patella alta (PA) is one of the primary correctable risk factors for patellofemoral instability (PFI). Both an accurate diagnosis of PA and a clinically relevant target for correction are necessary for optimal treatment. An ideal test for PA should relate the position of the patella to the femur rather than tibia, should do so with the quadriceps contracted and the patellar tendon under tension and should have good sensitivity and specificity. None of the currently used radiographic tests PA meet these criteria, most of which are based on the position of the patella relative to the tibia with diagnostic cutoffs based on 2 standard deviations from the mean rather than optimal sensitivity and specificity...
