Patellofemoral Joint Stress during Running with Added Load in Females
International Journal of Sports Medicine, 2020AbstractPatellofemoral joint (PFJ) pain syndrome is a commonly reported form of pain in female runners and military personnel. Increased PFJ stress may be a contributing factor. Few studies have examined PFJ stress running with added load. Our purpose was to analyze PFJ stress, PFJ reaction force, quadriceps force, knee flexion angle, and other ...

Patellofemoral joint stress during running in females with and without patellofemoral pain
The Knee, 2012Patellofemoral pain (PFP) is a common complaint among female runners. The etiology for PFP is frequently associated with increased patellofemoral joint stress (PFJS) and altered hip and knee joint kinematics during running. However, whether PFJS during running is increased among runners with PFP is unknown.

The Effect of Speed on Achilles Tendon Forces and Patellofemoral Joint Stresses in High-Performing Endurance Runners [PDF]
Scandinavian Journal of Medicine and Science in Sports, 2021 Achilles tendinopathy and patellofemoral pain are common running injuries associated with increased Achilles tendon (AT) forces and patellofemoral joint (PFJ) stresses. This study examined AT forces and PFJ stresses at different running speeds in high‐performing endurance runners. Twenty runners ran overground at four running speeds (3.3, 3.9, 4.8, and

Methods to assess patellofemoral joint stress: A systematic review
Gait & Posture, 2018Changes in patellofemoral joint (PFJ) stress are related to the development and course of PFJ dysfunctions. Different methods for PFJ stress calculation have been used, making the comparison of PFJ stress values across different studies difficult.

The Influence of Patella Alta on Patellofemoral Joint Stress During Normal and Fast Walking
Clinical Biomechanics, 2004To determine if persons with patella alta exhibit elevated patellofemoral joint stress compared to pain-free controls during normal and fast walking speeds.Twenty-four subjects (13 patella alta, 11 pain-free controls) participated.Sagittal and axial magnetic resonance images of the knee were obtained to quantify subject specific knee extensor mechanics

Clinical Biomechanics, 2014
Patellofemoral pain is common among runners and is frequently attributed to increased patellofemoral joint stress. The purpose of our study was to examine the effects of changing step length during running on patellofemoral joint stress per step and stress per mile in females with and without patellofemoral pain.Ten female runners with patellofemoral ...

In vivo quantification of the cat patellofemoral joint contact stresses and areas
Journal of Biomechanics, 1995A new method for in vivo measurement of patellofemoral joint contact areas, stresses, and patellar displacements, with joint loading approximating physiologic conditions was developed. Joint contact measurements were obtained using pressure sensitive film inserted directly between articular joint surfaces. Two-dimensional joint kinematics were measured

A Modeling Framework to Estimate Patellofemoral Joint Cartilage Stress In Vivo
Medicine & Science in Sports & Exercise, 2005Patellofemoral (PF) pain is common among athletes and may be caused by increased subchondral bone stress as a result of increased stress in the cartilage of the femur or patella. This article presents a modeling pipeline to estimate in vivo cartilage stress in the PF joint.The modeling pipeline uses the finite element method to calculate stresses and ...

Patellofemoral Joint Stress during Running with Alterations in Foot Strike Pattern
Medicine & Science in Sports & Exercise, 2015This study aimed to quantify differences in patellofemoral joint stress that may occur when healthy runners alter their foot strike pattern from their habitual rearfoot strike to a forefoot strike to gain insight on the potential etiology and treatment methods of patellofemoral pain.Sixteen healthy female runners completed 20 running trials in a ...
