After artificial shoulder replacement, several reasons may necessitate the substitution of individual implants or the entire artificial joint. This is referred to as a revision or exchange operation.

Causes that require a revision include loosening of the prosthesis, infections, wear of the polyethylene inlay or other components, but also injuries involving the artificial joint (e.g. falls).

It is important to recognise early when a revision becomes necessary. An excessive delay or late recognition may negatively affect the bone situation and, in the worst case, make the implantation of a revision prosthesis impossible. Regular exams by the orthopaedist minimise this risk.
