Background Excessive foot pronation during gait is frequently linked to patellofemoral pain syndrome (PFPS) development, due a proposed coupling of increased foot pronation with increased tibial and femoral internal rotation. However, there is a paucity of research which has compared kinematics associated with foot pronation between individuals with PFPS and controls. The aim of this study was ...

Background: Mobile health (mHealth) apps play an emerging role in managing chronic conditions. This study aimed to design, develop, and evaluate the usability of exercise therapy mHealth app individuals with patellofemoral pain syndrome (PFPS). Objectives: paper presents development, evaluation procedures conceptual mHelath app, called Vitoapp, using progressive web application (PWA) approach. ...

INTRODUCTION Patellofemoral pain syndrome (PFPS) is the most common running injury, and is characterized by pain under and/or around the patella during movement [1]. Although no biological cause for PFPS is known, recent biomechanical studies have shown that PFPS may be related to knee joint loading. Specifically, Stefanyshyn et al. [2] found that patients with PFPS experience increased knee ab...

CLINICAL SCENARIO Patellofemoral pain syndrome (PFPS) is one of the most common disorders affecting the lower extremities. To improve function and decrease pain, affected individuals often undergo a guided rehabilitation program. Traditional programs have concentrated on quadriceps strengthening and other knee-focused exercises, but recent literature suggests that adding hip-muscle strengthenin...

OBJECTIVES The aim of this study is to evaluate the usefulness of Magnetic Resonance Imaging (MRI) at 20° of knee flexion in patients with patellofemoral pain syndrome (PFPS) caused by suspected patellofemoral malalignment (PFM). MATERIAL AND METHOD Fifty MRIs were performed on 25 patients with PFPS secondary to suspected PFM based on clinical examination, and on 25 patients without PFPS (con...

Background Although excellent long-term clinical results have been reported for the total knee arthroplasty (TKA), 37% of patients have limited functional improvement one year after the surgery [1]. Patients with a clinical presentation of anterior knee pain could be diagnosed with patellofemoral pain syndrome (PFPS). Modified clinical classification of PFPS patients includes two main groups: w...

A common rehabilitation strategy for patellofemoral pain syndrome (PFPS), which lacks scientific evidence, includes pulling the patella medially with tape to reduce pain and increase the vastus medialis oblique (VMO) muscle activity. The purpose of this study was to examine the effect of various patellar taping procedures on force production, EMG activity of the VMO and vastus lateralis (VL) mu...

Objectives: Patellar maltracking is the main reason for pain and disability in patellofemoral pain syndrome (PFPS). Patellar taping can considerably reduce such pain and disability. This study compared the effectiveness of physiotherapy exercises and kinesio taping on the patellar position in women with PFPS (mean age 32.2±1.12 years) by using magnetic resonance imaging (MRI). Methods: ...

Background There is emerging evidence that foot orthoses are effective in the management of patellofemoral pain syndrome (PFPS), however the identification of those most likely to benefit from orthoses has not been adequately explored. The primary aim of this study was to develop a clinical prediction rule to help identify individuals with PFPS who are most likely to benefit from foot orthoses....

INTRODUCTION Patellofemoral pain syndrome (PFPS) is pervasive and debilitating in the sport of cycling. Currently, little is known about the underlying mechanism causing patellofemoral pain in cyclists. PURPOSE The purpose of this study was to determine whether temporal differences in the muscle activity of the vastus medialis (VM), vastus lateralis (VL), semitendinosus (ST), and biceps femor...
