Case: A 62-year-old man presented with a posterolateral knee dislocation sustained in a motorcycle collision initially managed nonsurgically. His treatment was complicated by recurrent dislocation from noncompliance with bracing and weight-bearing restrictions and by comorbidities including peripheral artery disease, type 2 diabetes, and heavy smoking and drinking. He was treated with a multiplanar knee-spanning external fixator and patellar tendon repair without further ligamentous reconstruction. This treatment provided a stable, functional knee with minimal pain.
Conclusions: In this complex, noncompliant patient with a subacute knee dislocation, knee-spanning biplanar external fixation and patellar tendon repair without ligament reconstruction were crucial in achieving a satisfactory outcome.

Background: In the knee joints of patients with recurrent patellar dislocation (RPD), an increased relative tibial external rotation (rTER) is often observed. However, the changes in this parameter pre- and postoperatively remain unclear.
Purpose: The purpose of this study was to reveal preoperative and postoperative changes in rTER in patients with RPD.

Background: Consequences of osteochondral fractures associated with patellar dislocation can be severe for younger patients. Precise 3-dimensional characterization of fracture location, size, frequency, and radiographic associations remain undefined in this population.
Purpose: (1) To define the topographic characteristics of osteochondral fractures in pediatric and adolescent patients with first-time patellar dislocations and (2) to determine the relationship between these characteristics and radiographic and patient factors.

Objectives: Long bone fractures with concomitant vascular injury have the potential to be life and limb threatening injuries, with increased risk for limb loss. There is currently no established surgical order of operations for orthopaedic and vascular intervention. This study compares injury classification, warm ischemia time and patient outcomes in patients with long bone fractures and associated vascular injury after orthopaedic versus vascular primary intervention.

Background: Spacer-type tibial osteotomy have been proven a novel and effective osteotomy to treat osteoarthritis, while lack of comparison with other surgical methods in younger patients. This study aims to evaluate the short-term clinical outcomes of spacer-type tibial osteotomy versus open wedge high tibial osteotomy (OWHTO) and unicompartmental knee arthroplasty (UKA) for Kellgren-Lawrence (K-L) grade 3-4 osteoarthritis (OA) in patients younger than 65 years.
Methods: This retrospective study analyzed a total of 224 patients with K-L grade 3-4 knee OA treated from March 2018 to November 2020.

Introduction And Importance: The estimated incidence of congenital dislocation of the knee, also referred to as genu recurvatum, is approximately 1 in 100,000 live births. The purpose of this report is to present a rare case of unilateral congenital knee dislocation, highlighting the clinical presentation and management.
Case Presentation: A 9-day-old female infant was born to a 30-year-old primigravida mother following an uncomplicated term pregnancy of 39 weeks and 4 days.
