by Vince Vacketta, DPM

The following is an overview of recent studies and findings related to TAA procedures.

Turkey (IN) BONEs: Yet another systematic review and more positive research surrounding the INBONE II TAA. The primary INBONE II shows a 96.5% survivorship at 44 months. In cases where revision TAA was performed using INBONE II, the survivorship rate was 93.9% at 25.9 months. Read more.

Mashed TATTRs: A multicenter study evaluated 36 total talus replacements and found a 94.5% survivorship rate at an average follow-up of 25 months. No difference was observed in outcomes between patients who received only total talus replacement (TTR) and those who underwent both TAA and TTR. Read more.

Trans-fibular perfection: A five-year outcome study conducted by design surgeon and senior author Lew Schon demonstrates a 100% survivorship rate for the Zimmer Trabecular Metal TAA. Additionally, there were no fibular non-unions. Read more.

TAA 10-year outcomes: Another systematic review of 595 patients who underwent TAA with 10-year follow-up shows variable survivorship rates ranging from 66% to 94.4%. The average time to failure spans from 4.6 to 13.8 years. The authors advocate standardizing survivorship definitions to enhance data interpretation. Read more.
