A proportion of patients will experience long term pain
following total knee arthroplasty (TKA), and some of
these patients ultimately undergo revision TKA. The
purpose of this retrospective study was to determine the
prevalence of complications seen on MRI in cohort of 113
patients who subsequently underwent revision TKA. The
spectrum of complications seen on MRI included the
following: polymeric synovitis in 32%, osteolysis in
27%, loosening in 22%, non-specific synovitis in 20%,
prominent synovial scarring and arthrofibrosis in 13%,
infection in 17%, and periprosthetic fracture in 1% of
patients. We compare our results with the causes for
revision TKA reported in the orthopedic literature.
