Knee prosthesis are medical devices used in knee replacement surgery. Based on whether the posterior cruciate ligament is preserved, primary total knee arthroplasty prostheses are classified into Cruciate Retention (CR) type and Posterior Stabilized (PS) type.Cruciate Retention Prosthesis (CR Prosthesis)It is indicated for patients with intact posterior cruciate ligament function, mild joint deformity and no severe osteoporosis.Posterior Stabilized Prosthesis (PS Prosthesis)It is suitable for patients with impaired posterior cruciate ligament function, severe joint deformity, osteoporosis or bone defects.
What are the components of a knee joint prosthesis? It is generally composed of three parts.Femoral ComponentIt replaces the articular cartilage of the femoral surface and is typically made of metals such as cobalt-chromium alloy or titanium alloy.Tibial ComponentIt replaces the structure of the human meniscus. It consists of a metal baseplate and a polyethylene liner to provide weight-bearing support.Tibial Baseplate replaces the articular cartilage of the tibial surface and is usually made of titanium alloy.
Why we need knee joint replacement? The most common reason for knee replacement surgery is to relieve pain caused by arthritis. People who need knee joint replacement surgery have trouble walking, climbing stairs and getting up from chairs. The goal of knee replacement prosthesis is to repair the surface of the damaged area of the knee and reduce knee pain that cannot be controlled by other treatments. If only part of the knee is damaged, the surgeon can usually replace that part. This is called partial knee replacement. If the entire joint needs to be replaced, the end of the femur bone and tibia will need to be reshaped, and the entire joint will need to be surfacing. This is called total knee replacement (TKA). The femur bone and tibia are hard tubes with a soft center inside. The end of the artificial part is inserted into the softer central part of the bone.
In summary, orthopedic knee implants are an important solution for treating patients with knee joint dysfunction. They provide patients with a way to restore their mobility and improve their quality of life, making them an indispensable choice in the field of orthopedics. With the advancement of technology, the design and materials of artificial knee joint are constantly improving, and it is expected to bring better treatment effects to patients in the future.
