The results of revision total knee arthroplasty using the Kinemax Plus Superstabilizer prosthesis at a minimum of 10 years are reviewed. The implant was designed specifically for revision surgery with integral distal and posterior femoral build-ups and a modular metal reinforcement rod within the tibial polyethylene post. Eighteen consecutive knees revised for aseptic loosening or instability were studied prospectively and reviewed at 10-13 years (mean 11.6 years). Mean HSS scores improved from 51 to 86, KS knee scores from 40 to 83 and KS function scores from 48 to 82, with 83% good and excellent results. There was one re-revision for recurrent instability. Additional distal femoral add-ons were needed in 33% and posterior add-ons were needed in 22% of cases. No post breakage or deformation occurred. The design rationale has proven successful with satisfactory clinical and radiographic outcomes.
