There is not enough evidence about how well this procedure works or how safe it is in the long term. This type of procedure can cause complications. So, it can only be done with special arrangements. This means you will have regular appointments afterwards to check how well it is working or if it has caused problems.
Articular cartilage protects the ends of the bones in the knee joint from friction during movement. Damage from injury or disease to a small (focal) area of the articular cartilage can cause pain, stiffness in the knee and reduced mobility. In this procedure, done under a general or regional anaesthetic, a surgeon makes a cut to access the knee joint. The damaged area of the cartilage and bone is removed, and replaced with a small artificial implant that restores the smooth surface (resurfacing). The aim is to reduce symptoms, allow immediate weight bearing and preserve joint function. It may also reduce or delay the need for a later knee replacement.
