Finite Element Analysis of Patellofemoral Contact Pressure with Varying Fixation of Transverse Patella Fractures

JBJS Open Access
Background:. Understanding patellofemoral contact pressure is crucial for knee biomechanics, as abnormalities can lead to joint issues. This study investigates the changes in contact pressure after surgical fixation of patellar fractures.

Femoral malrotation from diaphyseal fractures results in changes in patellofemoral alignment and in higher patellofemoral stress from a finite element model study

, 2018
International audienceBackground: Malrotation of the femur is a frequent complication in the management of a diaphyseal fracture. It is often responsible for pain and adverse functional results.

Comparative study of four types of patellofemoral ONLAY prostheses: Is there superiority of one design over another?

Journal of Orthopaedic Reports
Introduction: Patellofemoral osteoarthritis (PFOA) has been associated with anterior knee pain, stiffness, and functional impairment. The incidence of PFOA ranges from 2 % to 24 % in individuals over 55 years old.

Early osteoarthritis of the patellofemoral joint

, 2016
Patellofemoral joint cartilage lesions are associated with a variety of clinical situations including blunt trauma, lateral patella dislocations, or as a secondary development in the setting of abnormal joint loading.

Tibial Tubercle Anteromedialization Using the Multi-Directional Tibial Tubercle Transfer System

Video Journal of Sports Medicine
Background: Tibial tubercle osteotomy (TTO) can realign the patellofemoral joint and reduce patellofemoral contact stress. Anteriorization can reduce compressive patellofemoral loads and medialization shifts the pulling direction on the patella, thereby ...
