Orthopedic Implants

Orthopedic Implants

Orthopedic implants are a broad term that encompasses some artificial devices used to replace joints in the human body, such as the hip, knee, fingers, and shoulders. Looking back at the past, orthopedic implants were mainly aimed at the elderly, but now they are increasingly used for the entire population to treat arthritis or replace damaged joints. With the extension of people's lives and the demand for orthopedic implants from some young patients, there is a high demand for manufacturers to produce orthopedic implants that can last for a long time.

For hip implants, due to their load-bearing capacity requirements, the shape characteristics of the femoral cup and head are highly demanded. But the main reason for damage is usually due to hip joint wear, especially the production of fragments. For example, common femoral bone loss is due to osteolysis. Although not all the root causes are known, they can be attributed to many different factors, including reactions between heterologous and particle fragments, especially polymer fragments. Therefore, it is crucial to avoid wear and tear on the hip joint. This requirement usually leads to extremely strict tolerance requirements for the surface roughness of the hip joint. Hip joint manufacturing is controlled through international standards, including the international standard ISO 7206 (I-VIII).

The requirements for knee joint implants (and other orthopedic implants) are similar to those for hip joints, which require controlling their surface morphology and roughness to ensure that their performance meets standards. Taylor Hobson provides a range of measurement technology solutions to knee implant manufacturers to help them ensure product quality and improve its performance.
