Vertical axis dislocation with coronal fracture of the patella: A previously unreported injury pattern

Trauma Case Reports, 2015
The patella usually dislocates laterally. Less commonly, intra-articular dislocation occurs about either the vertical or horizontal axis. Patellar fractures are generally transverse with varying degrees of comminution, and less frequently vertical in the

Post patellectomy patellar tendon dislocation - An unusual injury

Journal of Orthopaedic Reports, 2022
Background: Acute lateral patellar dislocations are not uncommon and may account for 2–3% of all knee injuries. Patellectomy is usually performed as a last option in certain situations of comminuted patellar fractures where reconstruction is not possible

Total Knee Arthroplasty for Neglected Patellar Dislocation

, 2014
Neglected permanent post-traumatic patellar dislocation is rarely seen. In this group of patients, secondary osteoarthritis may develop within years, consequently, patients suffer from pain.

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

, 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 ...

Increased tibial tubercle-trochlear groove and patellar height indicate a higher risk of recurrent patellar dislocation following medial reefing

, 2021
Purpose!#!Identifying anatomical risk factors on recurrent dislocation after medial reefing is important for deciding surgical treatment. The present study aimed to retrospectively analyze the preoperative magnetic resonance imaging (MRI)-based ...

Epidemiology of Lateral Patellar Dislocation Including Bone Bruise Incidence: Five Years of Data from a Trauma Center

Orthopaedic Surgery
Objective Systematic summary of the epidemiology of patellar dislocation is rare. This study aims to investigate sex‐, age‐, type‐, injury causing events‐, incidence of bone bruise and time from last injury (TFLI)‐specific characteristics, and detail the

Anti‐inflammatory and osteogenic effects of transcutaneous electrical nerve stimulation in knee osteoarthritis rats via the regulation of the intestinal microbiota

Animal Models and Experimental Medicine, EarlyView.
Transcutaneous electrical nerve stimulation (TENS) improved knee osteoarthritis (KOA) in rats by regulating interleukin‐1β (IL‐1β), IL‐6, and IL‐8 expressions and the bone morphogenetic protein 2 (BMP‐2)/transforming growth factor β (TGF‐β) signaling pathway.

Systemic Hormonal Contraceptive Use Is Associated With Greater Odds of Rotator Cuff Tears, Shoulder Instability, Dislocation, and Other Shoulder Pathologies: A Propensity Matched Epidemiological Study

Arthroscopy, EarlyView.
Purpose To evaluate whether systemic estrogen‐only, progestin‐only, or combined hormonal contraceptives (HCs) are associated with increased risk of shoulder pathologies in reproductive‐age females. Methods A retrospective cohort study of female patients presenting to clinic from 2013 to 2020 and aged 13‐50 with 5 years of follow‐up was conducted using ...

Tibial Tubercle to Trochlear Groove Distance and Index in Children with One-Time versus Recurrent Patellar Dislocation: A Magnetic Resonance Imaging Study

Journal of Orthopaedic Surgery, 2016
Purpose To compare the tibial tubercle to trochlear groove (TT-TG) distance and index using magnetic resonance imaging (MRI) between children with one-time and recurrent patellar dislocation. Methods Records of first-time acute patellar dislocations from
