Locked Superior Patellar Dislocation

Orthopedics, 2016
Superior dislocation of the patella is a rare cause of knee locking, with fewer than 20 cases reported in the English literature. The vast majority of traumatic or even atraumatic knee locking cases are due to such varied conditions as meniscal tears, osteochondral lesions, osteoarthritis, and ligamentous tears.

Patellar dislocation in achondroplasia

Journal of Pediatric Orthopaedics B, 2008
The knee was assessed by normal plain radiographs in 20 achondroplasia patients (40 lower extremities), whose age ranged from 10.5 to 23 years. Five patients (seven knees) had permanent patellar dislocation. There was a significant difference between the achondroplasia group and control group (50 knees without skeletal dysplasia) for femoral sulcus ...

Bisect offset ratio and cartilaginous sulcus angle are good combined predictors of recurrent patellar dislocation in children and adolescents

Journal of ISAKOS, 2021
Objectives Recurrent patellar dislocation (RPD) is found most commonly in the juvenile population. While risk factors have been well-established in adults, there remains a paucity in radiographical data to define normal and pathoanatomical juvenile ...

Anatomy of patellar dislocation

Operative Techniques in Sports Medicine, 2001
Acute patellar dislocation is a common injury that can lead to disabling knee pain and/or recurrent instability. Recent research focuses on patellofemoral anatomy, on the injuries associated with acute patellar dislocation, and the specific contributions the injured structures make to patellar stability in intact knees.

Acute patellar dislocations

The American Journal of Sports Medicine, 1986
Of 27 patients sustaining primary patellar dislocations, 20 were treated with immobilization and subsequent physiotherapy (including nine patients who underwent arthrosocoy) and seven with immediate surgical stabi lization and lateral release. The patients with predis posing factors such as patellofemoral malalignment, abnormal patellar configuration,

Factors Associated With an Increased Risk of Recurrence After a First-Time Patellar Dislocation: A Systematic Review and Meta-analysis

American Journal of Sports Medicine, 2019
Background: Recurrent dislocations after a first-time lateral patellar dislocation may occur in more than 50% of patients and can cause long-term disability. Many factors have been suggested to influence the risk of recurrence. Purpose: To systematically

Episodic Patellar Dislocation

2014
This condition is defined by a history of one or more episodes of patellar dislocation confirmed by the patient or the physician and/or a radiographic abnormality due to a dislocation (fracture of the medial border of the patella or fracture of the lateral condyle).
