Using MRI, we reviewed 50 patients with painful TKRs and compared them with a group of 16 asymptomatic controls to determine the feasibility of using MRI in evaluating the rotational alignment of the components. Using the additional soft-tissue detail provided by this modality, we also evaluated the extent of synovitis within these two groups. Angular measurements were based on the femoral transepicondylar axis and tibial tubercle. Between two observers, there was very high interobserver agreement in the measurements of all values. Patients with painful TKRs demonstrated statistically significant relative internal rotation of the femoral component (p = 0.030). There was relative internal rotation of the tibial to femoral component and combined excessive internal rotation of the components in symptomatic knees, although these results were significant only with one of the observers (p = 0.031). There was a statistically significant association between the presence and severity of synovitis and painful TKR (p &lt; 0.001).<\/jats:p>\n                  <jats:p>MRI is an effective modality in evaluating component rotational alignment.<\/jats:p>","DOI":"10.1302\/0301-620x.94b9.28489","type":"journal-article","created":{"date-parts":[[2012,8,29]],"date-time":"2012-08-29T07:23:36Z","timestamp":1346225016000},"page":"1209-1215","source":"Crossref","is-referenced-by-count":55,"title":["MRI evaluation of rotational alignment and synovitis in patients with pain after total knee replacement"],"prefix":"10.1302","volume":"94-B","author":[{"given":"A.
