Prosthetic components are designed to last from two to four years, depending on how they are used. The socket is also designed to last for two to four years, although most sockets must be replaced sooner as a result of changes in the residual limb such as weight loss, revision surgery or increased activity level.
Cracking and popping noises, excessive hip pain and strain, and issues with alignment are all signs that a prosthesis is reaching the end of its wear cycle.
