摘要

Purpose

Revision total knee arthroplasty (rTKA) is more complex and carries higher risks than primary TKA, especially in patients aged ≥ 80 years. This study examines whether elective rTKA yields similar clinical outcomes and complication rates in octogenarians compared to septuagenarians (70–79 years).

Methods

From 2010 to 2022, we identified 57 patients aged ≥ 80 years who underwent their first rTKA with at least a two-year follow-up at a single institution. These patients were matched 1:2 based on rTKA indication with 114 patients aged 70–79 years. Data collected included demographics, revision indications, perioperative outcomes, complications, reinterventions, and Knee Society Scores (KSS). These variables were compared between septuagenarians and octogenarians with student-t tests or Mann-Whitney u tests.

Results

Aseptic loosening was the most common revision indication in both groups (32.8% of all cases). Septuagenarians received more constrained condylar knee (CCK) implants (51% vs. 23%), while octogenarians received more hinged implants (54% vs. 38%). At 2 years, septuagenarians had higher KSS Function scores (72.7 ± 14.9 vs. 56.8 ± 11.4, p < 0.001). Octogenarians experienced higher complication rates (26.3% vs. 9.6%, p = 0.006) and reinterventions (15.8% vs. 6.2%, p = 0.05).

Conclusion

Octogenarians undergoing rTKA exhibited lower functional outcomes and gains, along with higher rates of postoperative complications and reinterventions compared to septuagenarians. Further evaluation using patient frailty indices may improve understanding and help balance the risks and benefits of revision surgery in this population.
