The successful protocol involved arthroscopic microdrilling/ microfracture surgery followed by postoperative injections of autologous peripheral blood progenitor cells (PBPCs) and hyaluronic acid. [15] The procedure creates a blood clot scaffold on which injected PBPCs can be recruited and enhance chondrogenesis at the site of the contained lesion.
The surgery is performed by arthroscopy, after the joint is cleaned of calcified cartilage. Through use of an awl, the surgeon creates tiny fractures in the subchondral bone plate. [10] Blood and bone marrow (which contains stem cells) seep out of the fractures, creating a blood clot that releases cartilage-building cells.
This is not always the case and microfracture surgery is therefore considered to be an intermediate step. [citation needed] An evolvement of the microfracture technique is the implantation of a collagen membrane onto the site of the microfracture to protect and stabilize the blood clot and to enhance the chondrogenic differentiation of the MSCs.
Knee arthroscopy, or arthroscopic knee surgery, is a surgery that uses arthroscopic techniques. It has, in many cases, replaced the classic open surgery that was performed in the past. Arthroscopic knee surgery is one of the most common orthopaedic procedures, performed approximately 2 million times worldwide each year. [2]
