Socket Replacements
The prosthetic component that requires the most frequent replacement is the socket. The prosthetic socket, the component that the residual limb fits into, is based on a mold of the residual limb. This component usually requires replacement every 1 to five years. Replacement can also be required outside of this time frame. Anatomy/condition change and irreparable damage are the most common issues that require a socket replacement. This is also usually the most expensive component (unless microprocessor and/or myoelectric components are involved) because it's totally customized and labor intensive.
