Background: The aim of this study was to analyze the locations of the femoral attachments of the popliteus tendon (PT) and lateral collateral ligament (LCL) via magnetic resonance imaging (MRI) and cadaveric dissection in a Korean population and compare with literature standards to determine whether variability exists.
Methods: We retrospectively analyzed knee MRIs from 87 cases selected from January 2017 to December 2018. The relationship between the femoral attachment of PT and LCL was analyzed by MRI using PACS and Image J. In addition, the femoral attachments of each structure were identified and marked in 14 unpaired human cadaveric knees. Three-dimensional models were reconstructed, and the surface area, location and distances were analyzed.
Results: On MRI, the femoral attachment of PT was located at mean distances of 0.89 mm posterior and 9.35 mm inferior to the LCL femoral attachment. We identified three groups of PT locations relative to the LCL on MRI evaluation: parallel (63%), posterior (29%), and anterior (8%). On cadaveric evaluation, the femoral attachment of the PT was located at mean distances of 0.77 mm posterior and 8.90 mm inferior to the LCL femoral attachment. We also identified three groups of PT locations relative to the LCL on cadaveric evaluation: parallel (43%), posterior (36%), and anterior (21%).
Conclusions: Based on both MRI and cadaveric evaluations in a Korean population, the femoral attachment of the PT is located just distal to and posterior to the LCL. The differences between the centroids of the femoral attachments of the two structures was approximately 9.7 mm, suggesting that racially based anatomical differences of the posterolateral corner may exist.

Introduction: Numerous orthopaedic procedures including dynamic hip screw plating and various osteotomies require placement of a reference guide pin or K wire to direct bone cuts or for drilling screw holes. Appropriate positioning of these wires is a critical component of surgery. Irrespective of whether one is a seasoned surgeon or an apprentice, these wires often need repositioning and readjustment.

Background: Dual mobility (DM) implants in total hip arthroplasty provide excellent range of motion with low dislocation rates. A complication of this design is intraprosthetic dislocation (IPD), where the polyethylene (PE) liner dissociates from the femoral head. In older designs, IPD occurred due to a small head size and late PE wear with head-capture-mechanism failure.

Background: The aim of the study is to identify the potential risk factors for postoperative AKI in hip fracture patients.
Design And Methods: Using our local neck of femur (NOF) registration data, patient details were selected using inclusion and exclusion criteria. Electronic records of patients were assessed retrospectively, including blood results, radiological investigations, clinical documentation, and drug charts.

Removal of spontaneously fractured leads with their proximal ends migrated into the vascular space has not been analysed in detail thus far. The study aimed to compare the effectiveness of different approaches and auxiliary tools for removing fractured leads with migrated proximal ends. Retrospective analysis of 72 cases from a database containing 3847 TLEs (transvenous lead extraction).

Objective: To observe the clinical effect of internal heat acupuncture therapy for knee osteoarthritis of early to middle stages, and explore its influence on cartilage thickness.
Methods: A total of 44 patients with knee osteoarthritis of early to middle stages were treated with internal heat acupuncture therapy at points (most of them are located at the subpatellar fat pad, both sides of the patellar ligament, the tendon of the quadriceps and the attachment of the medial and lateral collateral ligaments), once a week, a total of 4 weeks of treatment. Before and after treatment, after 3 months of treatment completion (in the follow-up), the visual analogue scale (VAS) score, Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, frequency of 30-second chair stand test (30sCST), cartilage thickness of femoral intercondylar and knee joint ultrasound score were compared, and the clinical effect was evaluated.
