ORTHOPLASTY is a disposable device for treating subchondral bone lesions.
The subchondral bone plasty procedure is a minimally-invasive, fluoroscopically-assisted procedure that identifies and repairs subchondral bone defects, also named Bone Marrow Lesions (BMLs). The procedure is carried out with a minimally-invasive approach under fluoroscopy guidance along with arthroscopy, to target and manage of findings inside the joint.
The pathology is classified as a SIFK (Subchondral Insufficiency Fracture of the Knee) and in the initial stages of SONK (Spontaneous Osteonecrosis of the Knee). The patient that presents with this pathology, suffers from relatively early osteoarthritis and consults the clinical specialist as a result of intense pain that does not correspond to a significantly compromised radiographic scenario.
In fact, these lesions are not visible under X-Ray and only a diagnostic confirmation using MRI reveals a hyper-intense uptake signal in sequences sensitive to T2 fluids (hydrogen) and in STIR sequences.
The objective of the method is to reinforce subchondral bone lesions using the same principal as vertebroplasty and involves the percutaneous insertion into the bone rarefaction site, of an appropriate bone substitute or of an autologous bone graft enhanced with a concentrate of mesenchymal stromal cells.
