Double-Limb Graft Versus Single-Limb Graft Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Dislocation: A Meta-analysis of Randomized Controlled Trials and Cohort Studies

American Journal of Sports Medicine, 2022
Background: The medial patellofemoral ligament (MPFL) is the most important stabilizer of lateral dislocation of the patella. Single-limb (SL) and double-limb (DL) graft MPFL reconstructions have been increasingly used to treat recurrent patellar ...

Medial Patellofemoral Ligament Reconstruction for Adolescents With Acute First-Time Patellar Dislocation With an Associated Loose Body

American Journal of Sports Medicine, 2021
Background: The management of adolescents with acute first-time patellar dislocation with an associated loose body remains a debated topic. The rate of recurrent dislocation in these patients may be up to 61% if the medial patellofemoral ligament (MPFL ...

Development of a Multivariable Model Based on Individual Risk Factors for Recurrent Lateral Patellar Dislocation.

Journal of Bone and Joint Surgery. American volume, 2021
BACKGROUND Nonoperative treatment after first-time patellar dislocation is the standard of care. There is evidence that certain patients may be at high risk for recurrent instability.

Fixed (Congenital) Patellar Dislocation

Clinics in Sports Medicine, 2022
Congenital dislocation of the patella is a rare condition characterized by lateral dislocation of the patella that is irreducible without surgical correction. Although there is no clear inheritance pattern, it is associated with several congenital syndromes. Patients often demonstrate flexion contracture, loss of active knee extension, increased tibial

The Number of Patellar Dislocation Events Is Associated With Increased Chondral Damage of the Trochlea

American Journal of Sports Medicine
Background: Patellofemoral instability is associated with chondral injuries to the patella, trochlea, and lateral femoral condyle. Although studies have demonstrated an association between patellar dislocations and chondral injuries, the influence of the

Patellar dislocation in Kabuki syndrome

American Journal of Medical Genetics, 2002
AbstractWe describe four individuals (two females and two males) with Kabuki syndrome and recurrent dislocation of the patella. The age of diagnosis of patellar dislocation ranged from 11 to 23 years. One individual underwent excision of the free fragment and transfer of the tibial tuberosity with good outcome.

Patellar Subluxation and Dislocation

2021
Patellar subluxation/dislocation is common in children with an incidence of 11.9 to 43 per 100,000 (Keyes et al., Am J Orthop 47, 2018; Liu et al., Am J Sports Med 46:3299–306, 2017; Ries et al., J Knee Surg 28:265–78, 2015). It is a common cause of acute knee effusion with pain and discomfort, resulting in missed time from activity.
