There are >200,000 anterior cruciate ligament (ACL) ruptures each year in the United States, and, due to the poor healing properties of the ACL, surgical reconstruction with autograft or allograft tissue is the current treatment of these injuries. To regenerate the ACL, the ideal matrix should be biodegradable, porous, and exhibit sufficient mechanical strength to allow formation of neoligament tissue. Researchers have developed ACL scaffolds with collagen fibers, silk, biodegradable polymers, and composites with limited success. Our group has developed a biomimetic ligament replacement by using 3D braiding technology. In this preliminary in vivo rabbit model study for ACL reconstruction, the histological and mechanical evaluation demonstrated excellent healing and regeneration with our cell-seeded, tissue-engineered ligament replacement.

Introduction: The aim of this study was to establish an international consensus statement on the indications for the addition of a patellofemoral joint arthroplasty (PFJA) in patients with a unicondylar knee arthroplasty (UKA) and symptomatic progression of patellofemoral compartment osteoarthritis.

Materials And Methods: A systematic review of the literature was conducted, and the results used to inform the development of a statement by an expert working group. This was then evaluated and modified, using a Delphi process, by members of the European Knee Society (EKS).

Cranial cruciate ligament (CCL) disease causes variable stifle instability assessed by specific clinical tests. Radiographs are performed to measure the tibial plateau angle (TPA) for planning tibial plateau leveling osteotomy (TPLO) surgery. Concomitant damage to other intra-articular structures, for which clinical detection is unreliable, may occur and potentially affect the surgical outcome.

Introduction: the two most used types of prosthesis are posterior cruciate ligament preserving (CR) and posterostabilized (PS). Proponents of CR TKA cited greater stability, greater range of motion, better proprioception, and greater kickback associated with the native posterior cruciate ligament.

Objective: to assess the degree of pain, return of mobility and functionality of the joint of patients who had TKA, between the years January 2018 and December 2022 at the Juárez Centro Medical Surgical Unit, using their records as a study unit.

BACKGROUND Perineal injuries affecting the scrotum and penis are rare in pediatric patients, owing to the protective anatomy of the male genitalia. However, when such injuries do occur, timely surgical intervention is crucial. This kind of damage might not be life-threatening but could cause functional disorders and have a huge impact on the patients' psychological condition if not treated appropriately, especially as they enter puberty.
