Hip Replacement Augments Longevity

Data from Swedish hip replacement registry finds that total hip arthroplasty (THA) not only improves quality of life, it is also associated with increased life expectancy that lasts at least 0 years after surgery, especially in primary osteoarthritis (OA) patients. (Citation source: https://buff.ly/2CQW0cC)

Researchers studied the survival rate of 131,808 patients undergoing THA from 1999-2012.  There were 21,755 deaths (16.5%) with a median follow-up of 5.6 years.

After one year, survival was one percent better in THA patients and 3% by five years. By 12 years, survival was no longer different for THA patients compared to the general population.

The survival difference was significant mainly among patients diagnosed with primary osteoarthritis.

Increasing comorbidities, lower education and being single led to lower survival after THA. Poorer relative survival was seen with THA done for osteonecrosis of the femoral head, inflammatory arthritis and secondary osteoarthritis.
