Derotational Femoral Osteotomy for Treating Recurrent Patellar Dislocation in the Presence of Increased Femoral Anteversion: A Systematic Review

Orthopaedic Journal of Sports Medicine, 2021
Background: Studies on the clinical outcomes of derotational femoral osteotomy to treat recurrent patellar dislocation in the presence of increased femoral anteversion are limited. Purpose: To investigate the role of derotational femoral osteotomy in the

Morphological characteristics of femoral condyle in patients with high-grade femoral trochlear dysplasia based on MRI images

陆军军医大学学报, 2022
Objective To quantitatively measure the morphological parameters of femoral condyle based on MRI images so as to determine the effect of anterior-posterior femoral condyle geometry on patellar instability (PI) in patients with high-grade femoral ...

Mobile Bearing Total Knee Arthroplasty for Valgus Knee Osteoarthritis with Permanent Patellar Dislocation: A Case Report and Review of the Literature

Case Reports in Orthopedics, 2017
Permanent patellar dislocation with tibiofemoral joint osteoarthritis is a relatively rare condition. To treat this condition, total knee arthroplasty with proximal or distal realignment of the extensor mechanism has been reported.

Distalization of tibial tubercle osteotomy is not necessary for patients with recurrent patellar dislocation accompanied by patella alta and increased TT–TG distance

BMC Musculoskeletal Disorders, 2022
Background The aim of this study is to determine whether distalization of the tibial tubercle is necessary for patients with recurrent patellar dislocation accompanied by patella alta and increased TT-TG.

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

Current Concepts for Patellar Dislocation

Archives of Trauma Research, 2015
Context Patellar dislocation usually occurs to the lateral side, leading to ruptures of the Medial Patellofemoral Ligament (MPFL) in about 90% of the cases.

Combined Total Knee Arthroplasty and Medial Patellofemoral Ligament Reconstruction for Chronic Patellar Dislocation and Severe Osteoarthritis

Arthroplasty Today, 2021
Chronic patellar dislocation in the setting of severe knee osteoarthritis is a rare clinical problem. Surgical management often consists of total knee arthroplasty combined with realignment of the extensor mechanism.

The morphology of patella changed significantly after soft tissue correction for children with recurrent patella dislocation

BMC Musculoskeletal Disorders, 2020
Background Although morphological improvement of femoral trochlea has been investigated in children with patellar dislocation after surgery, whether the patellar shape changed under the same condition is still unknown.

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.
