Editorial Commentary: Biological Cartilage Repair Technique-An "Effective, Accessible, and Safe" Surgical Solution for an Old Difficult Biological Problem.

Achieving good long-term outcomes while treating chondral defects has always been a challenge. Several surgical techniques for regeneration of the articular cartilage have been proposed. Among them, osteochondral autograft transplantation and 2-step procedures such as autologous chondrocyte implantation have provided good results, promoting formation of new hyaline-like cartilage tissue, whereas other techniques such as microfracture result in fibrous cartilage and a less durable repair. Single-stage cell-based procedures are an attractive treatment option given the potential for cost savings and avoiding a second-stage procedure. We believe that 1-stage cartilage repair in the knee with a hyaluronic acid-based scaffold embedded with mesenchymal stem cells sourced from bone marrow aspirate concentrate has a prominent role in treating chondral defects because this is a simple technique that could improve the care of patients and be cost-effective in the near future.
