AI Article Synopsis

  • Articular cartilage injuries are prevalent, especially among the elderly and active individuals, leading to a need for effective treatments due to cartilage's poor ability to regenerate.
  • Regenerative medicine, particularly through tissue engineering, combines cells, biomaterials, and growth factors to enhance cartilage healing and overcome traditional therapies.
  • Current studies explore various cell sources and scaffolds to recreate the natural cartilage environment, aiming to develop effective solutions for cartilage regeneration.

Article Abstract

Articular cartilage injuries are common in the population. The increment in the elderly people and active life results in an increasing demand for new technologies and good outcomes to satisfy longer and healthier life expectancies. However, because of cartilage's low regenerative capacity, finding an efficacious treatment is still challenging for orthopedics.Since the pioneering studies based on autologous cell transplantation, regenerative medicine has opened new approaches for cartilage lesion treatment.Tissue engineering combines cells, biomaterials, and biological factors to regenerate damaged tissues, overcoming conventional therapeutic strategies. Cells synthesize matrix structural components, maintain tissue homeostasis by modulating metabolic, inflammatory, and immunologic pathways. Scaffolds are well acknowledged by clinicians in regenerative applications since they provide the appropriate environment for cells, can be easily implanted, reduce surgical morbidity, allow enhanced cell proliferation, maturation, and an efficient and complete integration with surrounding articular cartilage. Growth factors are molecules that facilitate tissue healing and regeneration by stimulating cell signal pathways.To date, different cell sources and a wide range of natural and synthetic scaffolds have been used both in pre-clinical and clinical studies with the aim to find the suitable solution for recapitulating cartilage microenvironment and inducing the formation of a new tissue with the biochemical and mechanical properties of the native one. Here, we describe the current concepts for articular cartilage regeneration, highlighting the key actors of this process trying to identify the best perspectives.

Background: Preventing worsening osteoarthritis (OA) in persons with early OA is a major treatment goal. We evaluated if different early OA definitions yielded enough cases of worsening OA within 2-5 years to make trial testing treatments feasible.

Methods: We assessed different definitions of early OA using data from Multicenter Osteoarthritis (MOST) Study participants who were followed up longitudinally.

Intra-Articular Injection of Human Bone Marrow-Derived Mesenchymal Stem Cells in Knee Osteoarthritis: A Randomized, Double-Blind, Controlled Trial.

Cell Transplant

January 2025

Division of Rheumatology, Department of Internal Medicine, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.

To assess the impact of a single intra-articular (IA) injection of bone marrow-derived mesenchymal stem cells (BM-MSCs) in patients with knee osteoarthritis (OA), a randomized, double-blind, placebo-controlled study was conducted. The study included 24 patients with knee OA who were randomly assigned to receive either a single IA injection of BM-MSCs or normal saline. Changes in the visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Knee Injury and Osteoarthritis Outcome Score (KOOS) after IA injection were assessed at 3, 6, 9, and 12 months.

Osteoarthritis (OA) is a common degenerative bone and joint disease with an unclear pathogenesis. Our study identified that the histone acetyltransferase encoded by Kat7 is upregulated in the affected articular cartilage of OA patients and in a mice model of medial meniscal instability-induced OA. Chondrocyte-specific knockdown of Kat7 expression exhibited a protective effect on articular cartilage integrity.

Despite advancements in chronic arthritis treatment, there remains a significant demand for advanced nanotechnologies capable of efficiently delivering a wide range of therapeutic agents to provide symptomatic relief and facilitate the healing of inflamed cartilage tissue. Considering the significant impact of hypoxia on the development and maintenance of chondral tissue, replicating its effects on stem cells could be a potential approach for the treatment of osteoarthritis (OA). Cobalt is a prominent hypoxia-inducing agent, owing to its ability to activate the hypoxia-inducible factor (HIF) pathway regardless of cellular oxygen levels.

Background Deep learning (DL) methods can improve accelerated MRI but require validation against an independent reference standard to ensure robustness and accuracy. Purpose To validate the diagnostic performance of twofold-simultaneous-multislice (SMSx2) twofold-parallel-imaging (PIx2)-accelerated DL superresolution MRI in the knee against conventional SMSx2-PIx2-accelerated MRI using arthroscopy as the reference standard. Materials and Methods Adults with painful knee conditions were prospectively enrolled from December 2021 to October 2022.
