Patellofemoral pain is a common and debilitating disorder. Elevated cartilage stress of the patellofemoral joint is hypothesized to play a role in the onset of pain. Estimating cartilage stress requires accurate measurements of contact area. The purpose of this study was to estimate patellofemoral joint contact areas in a group of healthy, pain-free subjects during upright, weight-bearing condi...

We assessed patellofemoral joint function by combining the measurement of maximal isometric extensor torque at the knee with clinical and radiological measurements in order to calculate the patellofemoral contact force. Eighteen volunteers established the normal ranges of results and the reliability of the system. Of the 39 patients with a variety of knee problems, 29 had anterior knee pain, an...

Patellofemoral pain is the most common chronic pathology in recreational runners. Female runners are at greater risk of developing patellofemoral pain, although the exact mechanism behind this is not fully understood. This study aimed to determine whether female recreational runners exhibit distinct knee loading compared to males. Fifteen males and 15 females recreational runners underwent 3D r...

OBJECTIVE To assess the effectiveness of supervised exercise therapy compared with usual care with respect to recovery, pain, and function in patients with patellofemoral pain syndrome. DESIGN Open label randomised controlled trial. SETTING General practice and sport physician practice. PARTICIPANTS Patients with a new episode of patellofemoral pain syndrome recruited by their general pra...

Patellofemoral disease is one of the most controversial management issues in orthopedic surgery. Nonoperative management as a prerequisite first line treatment is successful in the majority of cases. However, a small subset of patients with persistent pain after adequate rehabilitation will be potential candidates for surgical intervention. Careful assessment of the underlying pathomechanics is...

The conceptualization of factors responsible for the etiology of patellofemoral pain are changing. In the recent past, chondromalacia and malalignment were believed to be most important factors relative to the genesis of anterior knee pain symptoms. However, new evidence from Europe and North America indicates other factors may be more important, such as overuse of anatomically normal patellofe...

Pain in the kneecap (patellofemoral joint) or surrounding soft tissues (ligaments, tendons, etc.) might be grouped together under umbrella term patellofemoral pain syndrome. Squatting, sit-to-stand exercise, stair climbing activity, jogging, and running are all associated with a worsening of syndrome, chronic disease (2). Objective Methodology: The purpose this study is to evaluate efficacy kin...

Patellar maltracking is thought to be one source of patellofemoral pain. Measurements of patellar tracking are frequently obtained during non-weight-bearing knee extension; however, pain typically arises during highly loaded activities, such as squatting, stair climbing, and running. It is unclear whether patellofemoral joint kinematics during lightly loaded tasks replicate patellofemoral joint...

OBJECTIVES: To assess the feasibility of a 30-minute education session for patients with patellofemoral pain on levels catastrophizing and kinesiophobia. DESIGN: Randomised study SETTING: Three sites within single NHS Organisation in England. PARTICIPANTS: Thirty-one adult were screened inclusion, resulting twenty-four who had clinical diagnosis being randomised equally to either intervention o...
