A Minimum 2-Year Follow-up Using Modular Trabecular Metal Tibial Components in Total Knee Arthroplasty
Keywords:total knee arthroplasty, uncemented, cementless, trabecular metal, porous tantalum
INTRODUCTION: Early failure of tibial components remains a concern in total knee arthroplasty (TKA). Loss of fixation with cemented implants continues to be problematic in young, active patients. We sought to determine outcomes in patients receiving trabecular metal (TM) implants in a single-surgeon community hospital setting.
METHODS: A retrospective analysis was performed on 167 consecutive primary TKAs performed on 133 patients utilizing a TM tibial implant with a minimum two years follow-up.
RESULTS: Failure due to aseptic loosening occurred in 4 of the 167 cases (2.4%). Local and systemic complication rates were low. Length of hospital stay and tourniquet time data were also reported.
CONCLUSION: Overall complications were low in our cohort of patients receiving TM implants. Longer follow-up is necessary to determine if the outcomes we observed are sustained over time.
