Hip resurfacing is an alternative to hip replacement surgery. It has been used in Europe since 1998 and became a common procedure. It has been used in Europe since 1998 and became a common procedure. Health-related quality of life measures are markedly improved and patient satisfaction is favorable after hip resurfacing arthroplasty.
Stem cells, as a concept, originated as a theory in the 19th century to potentially allow certain tissues to self-renew. There are five types of stem cells, and MSC's are multi-potent, meaning they are cells that have the ability to develop into more than one type of specialized cell. Mesenchymal stem cells were originally discovered and ...
For the cell type, see Stem cell. Stem-cell therapy uses stem cells to treat or prevent a disease or condition. [1] As of 2016, the only established therapy using stem cells is hematopoietic stem cell transplantation. [2] This usually takes the form of a bone marrow transplantation, but the cells can also be derived from umbilical cord blood.
These transplanted cells thrive in their new environment, forming new articular cartilage. Autologous mesenchymal stem cell transplant. For years, the concept of harvesting stem cells and re-implanting them into one's own body to regenerate organs and tissues has been embraced and researched in animal models.
The human body's own cartilage is still the best material for lining knee joints. This drives efforts to develop ways of using a person's own cells to grow, or re-grow cartilage tissue to replace missing or damaged cartilage. One cell-based replacement technique is called autologous chondrocyte implantation (ACI) or autologous chondrocyte ...
Microfracture surgery. Left knee-joint from behind, showing interior ligaments. ( Lateral meniscus and medial meniscus are cartilage.) Microfracture surgery is an articular cartilage repair surgical technique that works by creating tiny fractures in the underlying bone. This causes new cartilage to develop from a so-called super-clot.
Gene therapy for osteoarthritis. Gene therapy for osteoarthritis is the application of gene therapy to treat osteoarthritis (OA). Unlike pharmacological treatments which are administered locally or systemically as a series of interventions, gene therapy aims to establish sustained therapeutic effect after a single, local injection.

Regenerative medicine. A colony of human embryonic stem cells. Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". [1] This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair ...
Hip resurfacing has been developed as a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap (usually made of cobalt-chrome metal), which is hollow and shaped like a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum (pelvis socket), replacing the articulating surfaces of the ...
Stem-cell transplantation was pioneered using bone marrow-derived stem cells by a team at the Fred Hutchinson Cancer Research Center from the 1950s through the 1970s led by E. Donnall Thomas, whose work was later recognized with a Nobel Prize in Physiology or Medicine. Thomas' work showed that bone-marrow cells infused intravenously could ...
