ARTICULAR CARTILAGE REPAIR
Articular cartilage is the smooth slippery layer covering the portion of bones inside the joint. Localised defects of this cartilage can be repaired by arthroscopic techniques like microfracture, mosaic-plasty, osteochondral transfer (OATS), or by two-stage procedure using cartilage cell culture techniques (ACI). In OATS or mosaic-plasty, healthy cartilage plugs from unimportant areas in the knee are used as “spare parts” to replace lost cartilage in important weight bearing areas.
In ACI, a small sample of healthy cartilage is harvested through arthroscopic surgery, and sent to the lab where it is processed and incubated to get a huge number of healthy cartilage cells in 6 to 8 weeks’ time. The knee is then opened and these cells are implanted using a gel matrix to cover the cartilage defect at the second stage operation.
