Due to demographic transition an increasing number of primary knee arthroplasty is
expected. A consequence is a rise in frequency in revision knee arthroplasty. Rotating
hinge prostheses are a development of former hinge prostheses, due to changes in implant
design the outcome of modern rotating hinge implants clearly improved in comparison
to former models. Interpretation of outcome in present literature is difficult due
to the small number of cases and the heterogeneous indications. Nevertheless the use
of rotating hinge knee prostheses in primary and revision arthroplasty is associated
with good clinical outcomes, when indicated appropriately.
