Differences in the stress distribution in the distal femur between patellofemoral joint replacement and total knee replacement: a finite element study [PDF]

Journal of Orthopaedic Surgery and Research, 2012
Background Patellofemoral joint replacement is a successful treatment option for isolated patellofemoral osteoarthritis. However, results of later conversion to total knee replacement may be compromised by periprosthetic bone loss.

Take your shoes off to reduce patellofemoral joint stress during running

British Journal of Sports Medicine, 2013
Aim Elevated patellofemoral joint stress is thought to contribute to the development and progression of patellofemoral pain syndrome. The purpose of this study was to determine if running barefoot decreases patellofemoral joint stress in comparison to shod running ...

Comparison of two methods of determining patellofemoral joint stress during dynamic activities

Gait & Posture, 2015
Joint specific models rely on muscle force estimates to quantify tissue specific stresses. Traditionally, muscle forces have been estimated using inverse dynamics alone. Inverse dynamics coupled with static optimization techniques allow for an alternative method in estimating muscle forces.

Influence of sex and knee joint rotation on patellofemoral joint stress [PDF]

Influence of sex and knee joint rotation on patellofemoral joint stress
application/pdf Purpose: Females are two times as likely to experience patellofemoral pain syndrome (PFPS) than males, however, the reason for this difference between sexes remains unclear. Patellofemoral joint (PFJ) stress is believed to contribute to PFPS alterations through knee joint rotation alignment, but the influence of knee joint rotation ...

Effects of Anterior Knee Displacement During Squatting on Patellofemoral Joint Stress

Journal of Sport Rehabilitation, 2018
Context:Squatting is a common rehabilitation training exercise for patellofemoral pain syndrome (PFPS). Patellofemoral joint stress (PFJS) during squatting with more anterior knee displacement has not been systematically investigated.Objective:To compare PFJS during squatting using 2 techniques: squat while keeping the knees behind the toes (SBT) and ...

Patellofemoral Joint Stress During Front and Back Squats at Two Depths

Applied Sciences
The purpose of this study was to identify differences between patellofemoral joint stress (PFJS), patellofemoral joint reaction force (PFJRF), quadriceps force, trunk and knee flexion angles, and horizontal position of applied load relative to the knee ...

Biomechanical effects of patellar taping in subjects with patellofemoral pain syndrome (PFPS). [PDF]

, 2008
PhDPatellofemoral pain syndrome (PFPS) is one of the most common musculoskeletal disorders affecting adults. Patellar taping provides an effective treatment in alleviating the symptoms of a high proportion of subjects who present with PFPS.

EFFECT OF HEEL LIFTS ON PATELLOFEMORAL JOINT STRESS DURING RUNNING. [PDF]

Int J Sports Phys Ther, 2017
Patellofemoral pain is a debilitating injury for many recreational runners. Excessive patellofemoral joint stress may be the underlying source of pain and interventions often focus on ways to reduce patellofemoral joint stress.Heel lifts have been used as an intervention within Achilles tendon rehabilitation programs and to address leg length ...

Biphasic Analysis of Cartilage Stresses in the Patellofemoral Joint [PDF]

Journal of Knee Surgery, 2015
The objective of this study was to examine the state of stress within the solid matrix of articular cartilage in the patellofemoral joint, using anatomically faithful biphasic models of the articular layers, with the joint subjected to physiologic muscle force magnitudes.

Influence of sex and knee joint rotation on patellofemoral joint stress

Acta of Bioengineering and Biomechanics, 2022
Purpose Females are two times as likely to experience patellofemoral pain syndrome (PFPS) than males; however, the reason for this sex difference remains unclear. Patellofemoral joint (PFJ) stress is believed to contribute to PFPS alterations through knee joint rotation alignment, but the influence of knee joint rotation conditions on PFJ stress ...
