For example, in the Study of the Treatment of Articular Repair (STAR), 49% of Carticel ACI patients underwent an SSP on the treated knee, during the 4-year follow up. The most common serious adverse events (up to 5% of patients), include arthrofibrosis and joint adhesions, graft overgrowth, chondromalacia or chondrosis , cartilage injury, graft ...
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 main target groups are patients with very small defects of the articular cartilage.
There are several different repair options available for cartilage damage or failure. "Maci" or autologous cultured chondrocytes on porcine collagen membrane, is a treatment to correct cartilage defects in the knee. This treatment has been approved by the Food and Drug Administration in 2016 for adult treatment only. [1]
The AMIC procedure was first proposed by Behrens in 2003. it aims to extend the use of microfracture surgery to larger cartilage lesions > 2.5 cm2. [5] Its clinical efficiency in autologous chondrocyte implantation (ACI), another cartilage repair technique for larger cartilage lesions, has been studied. [6] [7] [8]
Articular cartilage stem cell paste grafting was initially described by Kevin R. Stone M.D., a San Francisco-based orthopedic surgeon, in 1997 . The technique was devised in response to reports that many of the contemporary cartilage restoration procedures lead to the development of fibrocartilage, not true hyaline articular cartilage. Knowing ...
Marrow-nucleated cells are used every day in regenerative orthopedics. The knee microfracture surgery technique relies on the release of these cells into a cartilage lesion to initiate fibrocartilage repair in osteochondral defects. [13] In addition, this cell population has also been shown to assist in the repair of non-union fractures. [14]
The procedure is less effective in treating older patients, overweight patients, or a cartilage lesion larger than 2.5 cm. [11] Further on, chances are high that after only 1 or 2 years of the surgery symptoms start to return as the fibrocartilage wears away, forcing the patient to reengage in articular cartilage repair.
Autologous articular cartilage transfer from a non-weight-bearing area to the damaged area, called osteochondral autograft transfer system, is one possible procedure that is being studied. [147] When the missing cartilage is a focal defect, autologous chondrocyte implantation is also an option. [148]
