Which radiological parameters of the coracoid process influence the diagnosis of atraumatic subscapularis tears? Systematic review and meta-analysis.

Introduction: Accurate diagnosis of subscapularis tears remains challenging due to the limitations of physical examinations and imaging techniques. Therefore, specific radiological parameters have been proposed as predictors of atraumatic subscapularis tears to improve diagnostic sensitivity and accuracy. These parameters include coracohumeral distance (CHD), coracoglenoid angle (CGA), coracoid angle (CA), coracoid overlap (CO), and coracohumeral angle (CHA).

Three-Dimensional Printing Guided for Double Meniscal Allograft Transplantation.

In complex cases of meniscus allograft transplantation, such as in double transplants, and when they are combined with ligament reconstructions, there is a high risk of tunnel overlap, which may compromise graft integrity and lead to treatment failure. Additionally, matching the meniscal allograft size to the patient's knee anatomy is critical and challenging. To address these challenges, a preoperative protocol was developed using three-dimensional (3D) printing.

Patient-specific 3D tibial model: transforming meniscal allograft transplantation and surgical planning.

Background: Meniscal allograft transplantation (MAT) restores knee function by replacing a damaged or absent meniscus with a healthy allograft, helping to preserve joint stability, distribute the load, and reduce cartilage degeneration. However, traditional 2D imaging techniques fail to fully capture the knee's complex three-dimensional anatomy, making accurate surgical planning challenging. Computed Tomography (CT)-based 3D printing offers a patient-specific solution by generating anatomically precise tibial models, allowing for enhanced preoperative planning.

Combined Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction Using a Flexible Reaming System.

The combination of anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction represents a therapeutic modality that exhibits superior clinical efficacy for certain risk groups when compared with isolated ACL reconstruction. This approach is progressively gaining broader applicability owing to its inherent prospective advantages. Despite the absence of a universally acknowledged gold-standard surgical technique, several methods have been delineated for its implementation.
