Knee dislocation is an uncommon, potentially limb-threatening, knee injury. Most often caused by high-velocity trauma, it can also result from low- or even ultra-low-velocity trauma. Rapid identification of the injury, reduction, and definitive management are necessary to minimize neurovascular damage. We present a case of rotatory anterolateral knee dislocation sustained during a twisting sports-related event. Special emphasis is placed on diagnosing vascular injuries associated with knee dislocations.

Introduction: The extent of change in Patient Reported Outcome Measures (PROs) required to meet surgeon-defined satisfactory outcomes after isolated Medial Patellofemoral Ligament Reconstruction (MPFL-R) has not been reported. The primary aim of the study was to define the threshold value of maximal outcome improvement (MOI) in PROs associated with surgeon-defined satisfactory postoperative outcomes. The secondary aim was to identify the most effective PRO in predicting these outcomes and to evaluate the factors associated with it.

Objective: To compare tibial tubercle-trochlear groove (TT-TG) and tibial tubercle-Roman arch (TT-RA) distances in patients with patellar dislocation or subluxation, evaluate TT-RA reliability and reproducibility, and determine pathological threshold values for surgical treatment using magnetic resonance imaging (MRI) and computed tomography (CT).
Materials And Methods: Retrospective analysis included 259 patient and 262 control examinations of knee MRIs and/or CTs performed. TT-RA, TT-TG, and tibial tubercle-posterior cruciate ligament (TT-PCL) distances, Roman Arch height, trochlear sulcus angle, and total femoral condyle width were measured by two radiologists, and trochlear morphology was assessed.

Purpose: Patellofemoral instability is a common knee condition and often associated with trochlear dysplasia. Sulcus-deepening trochleoplasty is a surgical option to reshape the trochlear groove and stabilise the patella. Although this procedure is considered safe and effective, the development of postoperative patellofemoral chondral lesions remains a topic of concern.

Background: Correct sizing of Oxford Medial Unicompartmental Knee Replacement (OUKR) femoral component can be challenging. Incorrect sizing can increase risk of bearing dislocation or revision. This study aimed to assess the accuracy of a simple but novel templating method in sizing the femoral component in OUKR.
