Trabecular edema, also known as bone marrow edema (BME), is a traditional term describing the interstitial fluid accumulation at the trabecular bone marrow. The term was first used in 1988, [ 1 ] referring to the changes in the bone marrow due to inflammation . [ 3 ]
A study of United States community hospitals showed that in 2012, among hospitalizations that involved an OR procedure, knee arthroplasty was the OR procedure performed most frequently during hospital stays paid by Medicare (10.8 percent of stays) and by private insurance (9.1 percent).
Autologous matrix-induced chondrogenesis, which is also known as AMIC, is a biological treatment option for articular cartilage damage bone marrow stimulating technique in combination with a collagen membrane. It is based on the microfracture surgery with the application of a bi-layer collagen I/III membrane.

Arthroscopic lavage is a "cleaning up" procedure of the knee joint. This short-term solution is not considered as an articular cartilage repair procedure but rather a palliative treatment to reduce pain, mechanical restriction and inflammation. Lavage focuses on removing degenerative articular cartilage flaps and fibrous tissue.
The most commonly affected bone is the femur (thigh bone). [1] Other relatively common sites include the upper arm bone, knee, shoulder, and ankle. [1] Diagnosis is typically by medical imaging such as X-ray, CT scan, or MRI. [1] Rarely biopsy may be used. [1] Treatments may include medication, not walking on the affected leg, stretching, and ...
The most commonly used source of MSC's is bone marrow aspirate. Most of the adult bone marrow consists of blood cells in various stages of differentiation. [10] These marrow components can be divided into plasma, red blood cells, platelets, and nucleated cells. The adult stem cell fraction is present in the nucleated cells of the marrow.
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.
