Article Abstract
Proximal fibular osteotomy (PFO) was found to relieve pain and improve knee function in patients with medial compartment knee osteoarthritis (OA). Therapy redistributes the load applied from the inside to the outside and alleviates the load applied on the inside through fibula osteotomy. Therefore, the clinical effect of fibular osteotomy using the finite element (FE) method was evaluated to calculate the exact change in stress inside a knee joint with varus deformity. Using CT and MRI images of a patient's lower extremities, 3D models of the bone, cartilage, meniscus, and ligaments were constructed. The varus angle, representing the inward angulation of the knee, was increased by applying a force ratio in the medial and lateral directions. The results showed that performing proximal fibular osteotomy led to a significant reduction in stress in the medial direction of the meniscus and cartilage. The stress reduction in the lateral direction was relatively minor. In conclusion, the study demonstrated that proximal fibular osteotomy effectively relieves stress and redistributes the load in the knee joints of patients with medial compartment knee osteoarthritis. The findings emphasize the importance of considering force distribution and the position of fibular osteotomy to achieve optimal clinical outcomes.

Objective: To analyze the Schatzker classification and related epidemiological situation of posterolateral tibial plateau fractures (PTPFs), and analyze the curative effect of different surgical approaches and internal fixation methods according to the subtype of PTPFs, to provide a strategic basis for clinicians to treat posterolateral plateau fractures.
Methods: A comprehensive search was conducted across the PubMed, Embase, Cochrane Library, and Web of Science databases to identify PTPFs between 2000 and 2024. The epidemiological data related to PTPFs, including its injury reason, Schatzker and OTA/AO classification, combined injury, complication, fixation methods, function evaluation methods, and other data, were manually screened and retrieved for comparative analysis.

Background: Reconstructive surgery following head and neck cancer resection is inherently complex and technically demanding. Procedures such as osteotomy and flap inset involve a steep learning curve, yet opportunities for hands-on training are increasingly limited. Physical simulation using cost-effective, anatomically realistic models offers a promising solution.

Introduction: Syndesmotic injuries, particularly those involving the posterior inferior tibiofibular ligament (PITFL), are complex and often result in chronic pain and instability if not appropriately treated. The PITFL plays a crucial role in maintaining syndesmotic stability, especially in resisting rotational forces. This case report examines a PITFL injury involving two posterior fibular fragments, supporting the hypothesis that the superficial and deep components of the ligament function independently.

Background: Oral and maxillofacial tumors, particularly those requiring mandibular reconstruction, present significant clinical challenges due to the complexities involved in achieving precise surgical outcomes and ensuring post-operative stability. Traditional methods for mandibular reconstruction, such as freehand bending of titanium plates, often result in errors in osteotomy and reconstruction, compromising both the precision and stability of the procedure.
Methods: This study initially developed the Robot-assisted Augmented Reality Osteotomy Navigation System (RARONS) and constructed a virtual surgical plan using imaging data.

This article presents a descriptive review focused on the proximal tibiofibular joint (PTFJ), a synovial plane joint located posterolaterally beneath the lateral tibial plateau. The PTFJ facilitates axial load transmission, allows subtle tibiofibular motion, and works in conjunction with the distal syndesmosis to preserve ankle and knee function. Dysfunction-resulting from anatomical variation, trauma, instability, or degeneration-can lead to pain, mobility impairment, and nerve compression.
