摘要：
Results of isolated patellar revisions for failed metal-backed patellae remain controversial. Isolated patellar revisions from April 1993 to April 2000 were assessed for complication rates, the Knee Society score (KSS), implant survival, and radiological loosening. Twenty-nine knees were revised in patients aged 71.0 years (range, 61-87; SD, 6.2). At 67.0 months (range, 24-98 months; SD, 22.0), no patient underwent further revision. Knee scores improved by 26.5 (range, 9.0-44.0; SD, 10.9) while function scores improved by 25.0 (range, 0-50.0; SD,14.5) over pre-revision values. Early complications included 3 superficial wound infections, 1 hematoma, and a urinary tract infection in I patient. One patient had a subluxed patella. One patient had asymptomatic femoral osteolysis on radiological evaluation. isolated patellar revisions can be performed in low-demand, elderly patients with minimal patellar maltracking.
