Fatigue fracture of the pelvis after total knee replacements: report of a case.
Fatigue fracture of the pelvis in a 66-year-old woman with rheumatoid arthritis was recognized after bilateral total knee replacements. The fatigue fractures occurred sequentially and bilaterally in the superior and inferior pubic rami. Satisfactory recovery occurred in response to conservative treatment. The fracture of the right superior ramus failed to unite. Fatigue fracture should be suspected if there is pain in the pectineal region after knee arthroplasty.
