Abstract
In cases of tumours, severe bone loss, etc., special pros-theses are sometimes required. It is also important to have a prosthesis that permits a switch from a primary knee system to a revision knee to a hinged knee.
This paper discusses and demonstrates some locally-manufactured prostheses.
