Many patients are satisfied following total knee arthroplasty (TKA) surgery, but post-operative challenges occur. This study evaluated synovial reactions in patients with TKA and related pre-operative MRI findings to direct evaluation of retrieved tibial polyethylene liners from revision surgery. Patients with synovial response of 'arthrofibrosis' had less damage to the tibial insert than patients with a synovial response of 'polymeric'. MRI was able to distinguish specific synovial responses directly to clinically confirmed arthrofibrosis and aseptic loosening.
