…We identified 63,158 patients who had undergone total hip replacement and 54,276 who had total knee replacement between Jan 1, 1991, and Aug 10, 2011, and followed up these patients to a maximum of 20 years…
…researchers analyzed data from the Clinical Practice Research Datalink on just over 63,000 patients who had undergone a total hip replacement and 54,000 that had total knee replacements. The surgeries took place between January 1, 1991 and August 10, 2011. Researchers followed the patients for a maximum of 20 years, to see how they made out with their prosthetic joints…
Results showed the following:
- For total hip replacement, the 10-year implant survival rate was 95-96 percent, and the 20-year rate 85 percent.
- For total knee replacement, the 10-year implant survival rate was 96 percent, and 20-year rate 89 percent.
- The lifetime risk of requiring revision surgery in patients who went through either operation and were over the age of 70 was about 5 percent, with no gender differences.
- Younger patients, however, were at a higher risk for revision surgery. Men in their early 50s had an up to 35 percent increased risk of revision. Women in the same age group had an up to 20 percent increased risk.
