Summary

Total knee replacement is safe for patients 85 years or older. This study found similar complication rates and lower mortality in elderly patients undergoing knee surgery compared to a younger control group.

Area of Science:

  • Orthopedic Surgery
  • Geriatric Medicine
  • Evidence-Based Medicine

Background:

  • The safety and efficacy of total knee replacement (TKR) in extremely elderly patients (≥85 years) remain a subject of debate.
  • Age is often considered a contraindication for major orthopedic procedures, but its independent impact on TKR outcomes requires further investigation.

Purpose of the Study:

  • To evaluate age as an independent factor influencing early postoperative morbidity and mortality following total knee replacement.
  • To compare complication rates and mortality between elderly patients (≥85 years) and a younger control group undergoing TKR.

Main Methods:

  • A case-control study design was employed, matching 22 elderly patients (≥85 years) with a younger control group.
  • Patients were matched based on known predictive factors for nonsurgical postoperative complications.

  • Both groups received identical perioperative and postoperative management protocols.
  • Postoperative complications and mortality rates were compared between the groups. Standardized mortality ratios (SMRs) were calculated.

    • Main Results:

    • The incidence of one or more medical complications was similar between the elderly group (50%) and the control group (23%).
    • Mortality in the elderly group who underwent knee replacement was approximately half that of the general population (SMR = 0.53).

    Conclusions:

    • Age alone should not be a contraindication for performing total knee replacement in elderly patients.
    • Elderly patients undergoing TKR may benefit from specialized hospital care to optimize outcomes.
