A Magnetic Resonance Imaging–Based Clinical Prediction Model Accurately Identifies Patellar Instability Risk Using Common Patellofemoral Measurements

Arthroscopy, Sports Medicine, and Rehabilitation
Purpose: To predict parameters associated with patellar instability from magnetic resonance imaging (MRI) measurements using a machine learning model and to quantify the relative importance of radiographic risk factors that are associated with the ...

Arthroscopic management of patellar instability

, 2010
Several arthroscopic techniques have been described to address patellar instability. Most arthroscopic procedures focus on soft-tissue plication or tightening of the medial retinacular structures to correct lateral patellar instability.

Surgical Treatment of Patellar Instability in Children and Adolescents [PDF]

, 2018
Patellar instability in children and adolescents is caused by abnormalities of various knee structures. Instability of the patellofemoral joint can manifest as an acute dislocation, recurrent dislocation, habitual dislocation, and congenital dislocation.

Pathological threshold of patellar tendon-trochlear groove distance using magnetic resonance image in patients with patellar instability

, 2022
The objective was to evaluate and compare values of patellar tendon-trochlear groove distance (PT-TG) in individuals with and without patellar instability.

Editorial Commentary: Contact Is Not Containment: In High‐Grade Trochlear Dysplasia, the Patellotrochlear Index Quantifies Cartilage Overlap in the Absence of Osseous Constraint

Arthroscopy, EarlyView.
Abstract Patella alta remains among the most critical anatomical risk factors for recurrent patellofemoral instability and failure of patellar stabilization surgery. The Caton‐Deschamps index references the patella to the tibia by measuring the position of the patella relative to the anterosuperior margin of the tibial plateau.

Concomitant Medial Patellofemoral Ligament Reconstruction, Tibial Tubercle Osteotomy, Trochleoplasty, and Osteochondral Autograft Transfer to the Patella

Arthroscopy Techniques
Recurrent patellar instability increases the risk of developing patellofemoral arthritis, among other complications. Chronic patellar instability frequently evolves into a debilitating issue that necessitates surgical intervention.

INCREASED INCIDENCE OF ACUTE PATELLAR INSTABILITY AND PATELLAR INSTABILITY SURGERY ACROSS THE UNITED STATES IN PEDIATRIC & ADOLESCENT PATIENTS

Orthopaedic Journal of Sports Medicine, 2019
Background: Participation in organized sports has been increasing over the last several decades for pediatric and adolescent athletes in this country. It is hypothesized that the overall incidence of acute patellar dislocation in this population would ...

Anatomy of Lateral Patellar Instability

, 2010
Background A trend toward young women being at greatest risk for primary and recurrent dislocation of the patella is evident in the current literature. However, a causative factor is missing, and differences in the anatomical risk factors between men and
