Total Knee Arthroplasty in Patients With a Prior Tibial Plateau Fracture: A Long-Term Report at 15 Years
Section snippets
Patients and Methods
Patients who received a primary cemented TKA after a previous tibial plateau fracture between 1988 and 1999 were included in the study. Patients were identified through our total joint registry that has followed up all patients since 1969. Institutional review board (IRB) approval was obtained prior to initiation of the study.
Knee Society scores (KSSs) were recorded 12., 13.. All radiographs were reviewed by two of the authors (MPA and PvR). Loosening was assessed separately for femoral and
Clinical Outcomes
The mean postoperative Knee Society pain score significantly increased from 44 points (range, 0–80 points) preoperatively to 80 points (range, 40–90 points) at most recent followup (P = 0.0001). A previous open reduction and internal fixation (n = 38) or the use of an external fixation (n = 1) had no significant influence on the postoperative Knee Society pain score (P = 0.4).
The mean Knee Society function score significantly increased from 52 points (range, 30–85 points) preoperatively to 70 points
Discussion
There are few reports, with limited patient numbers and followup, on the mid-term to long-term outcomes of TKA after fractures of the tibial plateau 6., 7., 8.. The purpose of the present study was to evaluate the long-term results of TKA after a prior tibial plateau fracture.
At 15 years, the survival free of revision for aseptic loosening was 96%. The survivorship free of any revision was lower (82%) due mostly to revision for polyethylene wear. Of note, during the study period (1988–1999), all
