Revision total knee arthroplasty with modular cemented stems: long-term follow-up.
From 1989 to 1994, 72 patients (73 knees) were treated for an aseptic, failed primary total knee arthroplasty (TKA) at 1 institution with revision TKA using a posterior stabilized implant of 1 design with modular, fully cemented femoral and tibial stems. There were 70 knees in 69 patients followed for a minimum of 2 years, or until component rerevision or resection. The remaining 3 patients died or were followed up for less than 2 years. The median follow-up of living patients with retained components was 10.2 years. Four knees had both femoral and tibial components rerevised for aseptic loosening. One knee was rerevised for patellar loosening and polyethylene wear. Five- and 10-year implant survivorship free of revision for aseptic failure was 98% and 92%, respectively.
