Because mesenchymal stem cells may regenerate cartilage, cartilage growth in human knees using autologous cultured mesenchymal stem cells is under research and preliminary clinical use, and appears to be safe as of 2016. [11] An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system ...
Autologous chondrocyte implantation (ACI, ATC code M09AX02 ()) is a biomedical treatment that repairs damages in articular cartilage.ACI provides pain relief while at the same time slowing down the progression or considerably delaying partial or total joint replacement (knee replacement) surgery.
The selection and use of essential medicines: report of the WHO Expert Committee, 2017 (including the 20th WHO Model List of Essential Medicines and the 6th Model List of Essential Medicines for Children).

It is used to treat symptomatic, full-thickness cartilage defects of the knee with or without bone involvement. [2] [1] Autologous cultured chondrocytes on porcine collagen membrane is an autologous cellularized scaffold product. [1] This treatment is approved by the US Food and Drug Administration (FDA). [1] It is only administered to adults. [1]
Cartilage is a slow adapting substance. Where a muscle takes approximately 35 weeks to fully adapt itself, cartilage only undergoes 75% adaptation in 2 years. If the rehabilitation period is too short, the cartilage repair might be put under too much stress, causing the repair to fail.
Articular cartilage stem cell paste grafting was initially described by Kevin R. Stone M.D., a San Francisco-based orthopedic surgeon, in 1997 . The technique was devised in response to reports that many of the contemporary cartilage restoration procedures lead to the development of fibrocartilage, not true hyaline articular cartilage. Knowing ...
In 2021 OrthoTrophix, the developer of the drug reported that one-year study of 93 patients suggested that TPX-100 treatment was associated with significant and sustained improvements in critical knee functions, preservation of knee cartilage thickness, reduced pathologic changes in underlying bone, and a >60% decrease in use of pain ...
Another stem-cell therapy, called Prococvhymal, was conditionally approved in Canada in 2012 for the management of acute graft-vs-host disease in children who are unresponsive to steroids. [9] It is an allogenic stem therapy based on mesenchymal stem cells (MSCs) derived from the bone marrow of adult donors.
