Trabecular Metal Cones Combined With Short Cemented Stem Allow Favorable Outcomes in Aseptic Revision Total Knee Arthroplasty

Background The purpose of this study was to compare the functional outcomes and implant survivorship at a minimum 5 years follow-up several reconstruction techniques with or without metaphyseal cone stems variable length. Methods A retrospective comparative matched analysis performed from 2 prospectively collected databases. Only patients who underwent revision total knee arthroplasty procedures for aseptic causes using single design rotating hinge were analyzed. Patients separated into 3 groups: trabecular metal (TM) cones + short cemented (TM stem [SS]), TM long uncemented [LS]), no (NC) (NC LS). matching process based on age (±5 years) realized. Results About 99 included; 33 in SS group, LS NC group. mean time 9.3 years. significant difference improvement subscale pain, symptom, activities daily living, quality life Knee Injury Osteoarthritis Outcome score knee, function Society Score observed favor group compared other groups. At 8 survivorship, components free any cause 90.9% 84.9% 90.6% Conclusion use tibial combined offers identical survival rate better outcome associated metallic augments follow-up.
