This is an arthroscopic procedure (the key hole surgery). The thorough knee is visualised and explored to learn the extent of the lesion arthroscopically. The loose cartilage surrounding the lesion is removed with the special instrument. The process of thoroughly cleaning and preparing the defect is essential for optimum results. Once it is defined the lesion range 1-4 cm2 is treated with Microfracture.

Here in this technique multiple vertical small holes (microfracture) are created. Which are 3 to 4 mm apart to maintain the integrity of the osteochondral micro cylinders. The depth created is up till tough superficial tough bony platform and not in the soft bone or marrow but just the give way of hard subchondral bone. This release the bone marrow (mesenchymal cells or stem cell) and the blood cells. Together they form a “super clot” and this is the foundation for the new tissue development. After a span of few weeks 4 – 8 weeks a new fibrous cartilage cells grows over the bare bone (degenerative lesion). This give a protective coating to the joint and make it pain free. This process takes around 6 months to consolidate and many years of knee survival.
