Golden arches sign (knees)

Last revised by Ian Bickle on 15 Oct 2018

The Golden arches sign is a nuclear medicine sign often seen on bone scan in patients with total knee prosthesis.

The femoral condylar prosthesis results in two central photopenic regions with two 'hot' arches formed around the periprosthetic region.

This finding is non-specific and may suggest post-surgical reaction, infection or loosening.
