Commentary on“The deterministic condition for the ground reaction force acting point on the combined knee valgus and tibial internal rotation moments in the early phase of cutting maneuvers in female athletes”

*** For decades,substantial disagreement has persisted as to whether dynamic knee valgus is the cause of the majority of anterior cruciate ligament(ACL)injuries or rather the result of the ACL rupture.1 Consequently,great effort and expense has gone into capturing 3-dimensional kinetics and kinematics from live athletes to drive in vitro and in silico models of ACL injury in order to elucidate the actual mechanism of injury,as these factors have been demonstrated to be surrogates of intraarticular structural loading on the ACL.2,3 The elucidation of injury mechanisms for non-contact ACL injuries is of great medical value as such knowledge consequently permits quantified examination and validation of interventions and their respective effectiveness in both prevention and rehabilitation of these traumatic knee injuries.

Mesenchymal Stromal Cells and Their Uses in Bio-Regenerative Therapies for Bone and Cartilage: A Review

引用

Open Journal of Regenerative Medicine 2024年第1期13卷 1-19页

作者： nathan Smernoff Texas College of Osteopathic Medicine University of North Texas Health Science Center Fort Wort Texas USA

Mesenchymal stromal cells (MSCs) are a top candidate for new clinical treatments in the repair of bone and cartilage. In several clinical trials, they have shown reliable, effective, and safe management of inflammation, pain, and the regenerative capabilities of resident tissues. MSCs are likely derived from pericytes. They modulate the environment they are placed in by secreting immunomodulatory and signaling molecules to reduce inflammation and direct resident cells to create new tissues. They are easily isolated from several different adult tissues, and inexpensive to grow in a lab. However, a mistake made in the initial classification of MSCs as stem cells has created deeply engrained misconceptions that are still evident today. MSCs are not stem cells, despite a large fraction of research and therapies using the name “mesenchymal stem cells”. This mistake creates false narratives attributing the observed positive outcomes of MSC treatments to stem cell characteristics, which has led to distrust in MSC research. Despite inconsistencies in their classification, MSCs demonstrate consistent positive effects in numerous animal studies and human clinical trials for non-unions and osteoarthritis. With an aging population, regenerative techniques are very promising for novel therapies. To produce trusted and safe new treatments using MSCs, it is essential for the International Society for Cellular Therapies to re-establish common ground in the identity, mechanism of action, and isolation techniques of these cells.
