What is the term used to describe the settling of a prosthetic component?

The term used to describe the settling of a prosthetic component is subsidence. In the context of orthopedic implants, subsidence refers to the downward movement or settling of a prosthetic device, often occurring within the bone or surrounding tissue. This phenomenon can lead to a loss of stability or a decrease in joint function, which may require further intervention, such as revision surgery or more intensive rehabilitation.

Subsidence is particularly significant in joint replacements where the implant must achieve a secure fixation to bone to function effectively. Over time, various factors such as the patient's weight, activity level, and the quality of bone in which the implant is anchored can affect subsidence. Recognizing and addressing this issue is crucial for ensuring the longevity of orthopedic implants and the overall success of surgeries.
