Abstract :
Objective: To evaluate the complication rate of total knee arthroplasty
(TKA) in octogenarian patients and identify predictive factors. Meth-
ods: The study comprised 70 octogenarians and 70 non-octogenarian
patients as control group, all submitted to TKA. We analyzed the
medical records of these patients, seeking for complications during
the first postoperative year. Regarding the risk factors, we evaluat-
ed: age, sex, race, American Society of Anesthesiologists score,
body mass index, smoking, hypertension and diabetes mellitus.
Results: In the control group, the incidence of complications was
7.1%. Whereas in the octogenarian group it was significantly higher,
reaching 34.3% (OR 6.8; 95% CI 2.4-19.1). We found no association
to sex, skin color, and comorbidities. Age is an independent risk
factor for postoperative complications. Our data may help patients
to acknowledge the risks of undergoing primary TKA and physicians
to assess and adjust perioperative risk. Conclusion: The incidence of
postoperative complications is significantly higher in octogenarians.
