Age and Weight Affect Total Hip Replacement Revisions
December 24, 2012
According to a recent study, age and body size may impact the risk of revision of total hip replacement. Results showed that patients who were taller, heavier or 75 years of age and younger had increased odds of revision…
…Elizabeth A. Wright, PhD, of Brigham and Women’s Hospital, and colleagues set out to study which factors might affect the risk of revision of total hip replacement surgery.
… While most joint replacements are successful, about 10 percent of implants will fail, requiring revision to replace the old implant with new parts.
Dr. Wright and her fellow researchers found that a number of factors increased the odds of revision after total hip replacement. These included:
- age 75 years or younger, with an odds ratio of 1.52
- being taller, with an odds ratio of 1.40
- being heavier, with an odds ratio of 1.66
- cemented femoral component (part of the implant), with an odds ratio of 1.44
- other previous orthopedic surgery, with an odds ratio of 1.45
- living with others (versus alone), with an odds ratio of 1.26
The analysis data set contained 719 of 836 case – control pairs with complete data for analysis variables.
