Prosthetic subsidence refers to the sinking or settling of a prosthetic implant into the surrounding bone. This phenomenon can lead to joint instability, which is a potential consequence that can significantly affect a patient's overall function and comfort. When a prosthesis is not securely anchored due to subsidence, it may not provide the stability needed for proper joint function, resulting in abnormal movements, pain, and a reduced ability to perform daily activities.

In contrast, consequences such as increased joint range of motion, improved muscle strength, or enhanced flexibility are not associated with subsidence. Instead, these factors suggest a healthy functioning joint, which is compromised when a prosthetic device is unstable. Stability is crucial in maintaining the integrity of the joint, enabling effective load bearing, and protecting the surrounding structures from further injury or degradation.
