A 65-year-old woman presented with right elbow pain after a fall. Imaging showed an avulsion fracture of the olecranon. The patient subsequently underwent surgery using the suture bridge technique with anchors. However, loosening was observed intraoperatively. Therefore, a McLaughlin cerclage with an artificial ligament was added, resulting in a rigid fixation. Bone union was achieved at 4 months postoperatively. At 18 months postoperatively, no limitation was observed in the range of motion of the elbow joint; the disabilities of the arm, shoulder and hand score was 0. McLaughlin cerclage with an artificial ligament provided additional fixation, demonstrating greater strength compared with suture anchors and minimizing the risk of cut-through in the osteoporotic bone. This approach offers a promising alternative for such cases by combining firm fixation with a reduced risk of complications, particularly in older patients with osteoporosis.

Ligament tears can strongly influence an individual's daily life and ability to engage in physical activities. It is essential to develop artificial scaffolds for ligament repairs in order to effectively restore damaged ligaments. In this experiment, the objective was to evaluate fibrous membranes as scaffolds for ligament repair.

The anterior cruciate ligament (ACL) is one of the most injured ligaments, with approximately 100,000 ACL reconstructions taking place annually in the United States. In order to successfully manage ACL rupture, it is of the utmost importance to understand the anatomy, unique physiology, and biomechanics of the ACL, as well as the injury mechanisms and healing capacity. Currently, the "gold standard" for the treatment of ACL ruptures is surgical reconstruction, particularly for young patients or athletes expecting to return to pivoting sports.

Background: The individual variation in on-snow performance outcomes after anterior cruciate ligament (ACL) reconstruction (ACLR) in elite alpine ski racers has not been reported and may be influenced by specific injury characteristics.
Purpose: To report the performance statistics of elite ski racers before and after ACLR and to identify surgical and athlete-specific factors that may be associated with performance recovery.
Study Design: Descriptive epidemiological study.

This Technical Note describes a surgical approach that combines circumferential fiber augmentation with transtibial pullout repair for the treatment of medial meniscal posterior root tears. To address the challenge of meniscal extrusion and subsequent joint space narrowing that predisposes to osteoarthritis, this technique uses an artificial ligament to add circumferential collagen fiber reinforcement to improve meniscal extrusion. This integrated approach is designed to address the limitations of conventional tibial pullout repairs by potentially providing better results in preventing meniscal extrusion.

While TGF-β3 promoted defect healing in a primate baboon skull defect model and patients, it remains unclear whether TGF-β3 affects the formation of osteoclasts and bone resorption between osteogenesis and osteolysis. Analysis of the full transcriptome of hPDLSCs (human periodontal ligament stem cells) revealed that the expression of RANKL was significantly up-regulated after TGF-β3 treatment during osteogenesis, which suggests its involvement in clock-controlled autophagy in bone metabolism. TRAP staining and bone resorption lacunae were used to assess the osteoclasts formed from RANKL-induced differentiated BMMs.
