A retrospective cohort study and a comparative literature review were undertaken to determine outcomes and survival/mortality rates among nonagenarian patients who underwent total joint arthroplasty (TJA). Thirty-nine patients who underwent TJA (14 hips, 25 knees) aged 90+ years were identified from a database of 9817 primary TJA cases performed at one hospital between 1998 and 2010. Findings were compared to synthesized data from relevant published literature review (LR). The mean age was 91.3 (±1.4) years, 79.5% were rated by the American Society of Anesthetists as 3+. Medical complication rate was 25.6% vs 36.2% for LR cases (P = .219). Perioperative death rate was 2.6% vs 2.1% among LR cases (P = 1.000). At 3.8-year follow-up, mortality rate was 59% (LR, 58.2%; 5.1 years), with a mean age of 95.2 (±3.5) years at death (LR, 96.3 ± 3.4). Excellent clinical outcomes were achieved. Primary TJA remains a viable and effective procedure in nonagenarian patients.
