Although, various pathologies can cause BML seen on magnetic resonance imaging
(MRI), in this technical note we would like to focus on treating the lesions associated
with osteoarthritis (OA) in the knee joint. The role of the subchondral bone in
transferring loads within the knee joint, as well as in cartilage homeostasis is well
established. In addition, cartilage and subchondral bone are increasingly considered as
an osteochondral unit, rather than as two separate structures. The knee OA, along with
insufficiency fracture, is one of the main indications for the treatment of painful BML.
Nowadays, there is a growing interest in this field and new approaches are developed.
Our technique can be defined as a surgical procedure aimed directly at pathology
within the subchondral bone and was named osteo-core plasty. It consists of two parts.
The first one is decompression of bone marrow to decrease intra-osseous pressure.
The second part is administration of bone marrow aspirate concentrate for better
healing potential and bone autograft to deliver supportive tissue. It should be noted,that
the cause of BML must be known before performing this kind of treatment.
