Purpose: The purpose of this study was to compare the clinical outcomes of septic and aseptic revision total knee arthroplasty.
Materials and Methods: This study compared the clinical and radiographic results of 12 septic and 10 aseptic revisions. All septic revisions were treated with two-stage reimplantation using an articulating cement spacer. The range of motion, Knee Society score, WOMAC score, and radiographic results of the American Knee Society were assessed.
Results: The preoperative data, which included the average range of motion, Knee Society score, WOMAC score and femoro-tibial angle, were similar in both groups. At the final follow-up, the average range of motion was similar in the two groups: 102.5o in the septic revisions, and 114.5o in the aseptic revisions (p=0.070). In addition, the Knee Society score, WOMAC score and femoro-tibial angle were similar in both groups. There was no loosening or failure of either component observed in any case. A patellar tendon rupture was observed in one septic revision after surgery.
Conclusion: Two-stage reimplantation using an articulating cement spacer in septic revisions could achieve functional results that are compatible to aseptic revisions.
