Comparison of Bone Bruise Pattern Epidemiology between Anterior Cruciate Ligament Rupture and Patellar Dislocation Patients—Implications of Injury Mechanism

Bioengineering, 2023
Different bone bruise patterns observed using magnetic resonance imaging (MRI) after non-contact anterior cruciate ligament (ACL) rupture and lateral patellar dislocation may indicate different knee injury mechanisms.

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

Pathological Thresholds of Segmental Femoral Torsion in Patients With Patellar Dislocation: Influence on Patellofemoral Malalignment

Orthopaedic Journal of Sports Medicine, 2022
Background Femoral torsion can be evaluated from different femoral segments. The pathological thresholds for femoral torsion of different segments and the influence of segmental femoral torsion on patellofemoral alignment remain unknown.

Effect of Patellar Morphology on the Risk of Osteochondral Fracture after Patellar Dislocation: A Cross‐sectional Study

Orthopaedic Surgery
Objective The risk of osteochondral fracture (OCF) after patellar dislocation has been shown to be related to patellofemoral anatomy, but its relationship to patellar morphology remains unknown.

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

Clinical Outcomes After Medial Patellofemoral Ligament Reconstruction With Suture Fixation of the Gracilis Tendon via Transosseous Tunnels

Orthopaedic Journal of Sports Medicine, 2020
Background: Several fixation methods have been introduced in medial patellofemoral ligament (MPFL) reconstruction. However, the optimal management of patients with recurrent patellar dislocation remains controversial.

Missed Transient Patellar Dislocation in Younger Patients With Traumatic Knee Injuries

Journal of Orthopedic and Spine Trauma, 2016
Background: Acute patellar dislocation is a common injury, with up to 40% of the cases missed due to a high rate of spontaneous reduction. Complications mainly arise due to osteochondral fractures, resulting in patellofemoral osteoarthritis and rupture ...
