Mortality Rate of Total Hip Arthroplasty (THA) Operations
- The mortality rate for THA operations varies depending on the age group and comorbidities of the patients, with a range of 0.1% to 0.9% in the short-term (30-day to 90-day) period 1, 2, 3, 4, 5.
- A study published in 2002 reported a 3-month mortality rate of 0.4% to 0.7% for THA operations in the United Kingdom 1.
- Another study published in 2018 found that octogenarians (80 years or older) had a higher mortality rate (0.9%) compared to younger patients (0.1%) after THA operations 2.
- A 2023 study reported an overall 30-day mortality rate of 0.69% after revision THA, with higher mortality rates observed in older patients and those with comorbidities such as malnutrition and chronic kidney disease 3.
- A nationwide cohort study published in 2014 found that mortality rates after THA and total knee arthroplasty (TKA) have decreased substantially since the early 1990s, despite patients having more presurgical comorbidity over time 4.
- A 2021 study reported mortality rates of 6%, 8%, 14%, and 49% at 90 days, 1 year, 2 years, and 5 years, respectively, after primary THA in nonagenarians (90-99 years) 5.
Factors Affecting Mortality Rate
- Age: Older patients, particularly octogenarians and nonagenarians, have a higher mortality rate after THA operations 2, 3, 5.
- Comorbidities: Patients with comorbidities such as malnutrition, chronic kidney disease, and diabetes have a higher mortality rate after THA operations 2, 3.
- Type of surgery: Revision THA has a higher mortality rate compared to primary THA 3.
- Surgical technique: Uncemented stem fixation was associated with a higher risk of intraoperative femur fracture in nonagenarians undergoing primary THA 5.
