Cartilage replacement is an innovative solution for knee pain or problems with knee function due to cartilage loss. As its name implies, this procedure aims to replace damaged cartilage with healthy cartilage, allowing the knee joint to glide smoothly and avoiding bone-on-bone contact. Cartilage replacement is a viable option for individuals who have lost knee cartilage due to sudden injury, or gradual deterioration through arthritis.
There are two types of cartilage replacement procedures that can be used to provide needed hyaline cartilage, which is the cartilage that bears weight in-between the thigh and shin bones. Information about these cartilage replacement procedures – osteochondral autograft transfer system (OATS) and autologous chondrocyte implantation (ACI) – is provided below.
