Tendon and ligament injuries caused by trauma and degenerative diseases are frequent and affect diverse groups of the population. Such injuries reduce musculoskeletal performance, limit joint mobility, and lower people's comfort. Currently, various treatment strategies and surgical procedures are used to heal, repair, and restore the native tissue function. However, these strategies are inadequate and, in some cases, fail to re-establish the lost functionality. Tissue engineering and regenerative medicine approaches aim to overcome these disadvantages by stimulating the regeneration and formation of neotissues. Design and fabrication of artificial scaffolds with tailored mechanical properties are crucial for restoring the mechanical function of tendons. In this review, the tendon and ligament structure, their physiology, and performance are presented. On the other hand, the requirements are focused for the development of an effective reconstruction device. The most common fiber-based scaffolding systems are also described for tendon and ligament tissue regeneration like strand fibers, woven, knitted, braided, and braid-twisted fibrous structures, as well as electrospun and wet-spun constructs, discussing critically the advantages and limitations of their utilization. Finally, the potential of multilayered systems as the most effective candidates for tendon and ligaments tissue engineering is pointed out.

Osteoarthritis (OA) is heterogeneous and involves structural changes in the whole joint, such as cartilage, meniscus/labrum, ligaments, and tendons, mainly with short T2 relaxation times. Detecting OA before the onset of irreversible changes is crucial for early proactive management and limit growing disease burden. The more recent advanced quantitative imaging techniques and deep learning (DL) algorithms in musculoskeletal imaging have shown great potential for visualizing "pre-OA.

Background: The aim of this study was to predict intraoperative graft diameter with our new method by evaluating the cross-sectional areas (CSAs) of the hamstrings in axial sections of MRI.
Methods: This study included 78 patients who underwent single-bundle ACLR between 2022 and 2023. MRIs of the patients were evaulated preoperatively and four CSAs of the hamstring tendons were measured in two different regions by two participants.

Background: Sports-related injuries remain a significant problem for collegiate baseball players. Although some studies reported the epidemiology of sports-related injuries among collegiate baseball players, the latest information on sport-related injuries should be provided.
Purpose: To examine the current trends of sports-related injuries among collegiate baseball players in the Pacific 12 (PAC-12) Conference.

Revision of anterior cruciate ligament reconstruction presents various challenges not encountered in the primary settings, including malpositioned tunnels, tunnel widening, and the lack of consensus on the ideal graft to be used. This Technical Note describes a one-stage anterior cruciate ligament reconstruction revision using a bone-patellar tendon-bone autograft combined with lateral extra-articular tenodesis. This technique represents the ideal approach to tackle complex revision cases primarily characterized by tibial and femoral tunnel osteolysis and rotational knee instability.

The medial patellofemoral complex provides the primary static restraint to lateral patellar translation and is composed of the medial patellofemoral ligament and medial quadriceps tendon femoral ligament. Multiple techniques including medial patellofemoral ligament and/or medial quadriceps tendon femoral ligament reconstruction have demonstrated good results; however, modification of the femoral fixation technique is required for skeletally immature patients or revision cases in which anatomic bony fixation on the femur is not possible. This technique describes an all-soft-tissue procedure for single-bundle medial patellofemoral complex reconstruction in which the graft is fixed on the adductor tendon while using the medial collateral ligament as a distalizing pulley, for anatomic and isometric recreation of the native ligament.
