Men have better function before and after knee replacements

24 March 2015

A new study has found that, although both genders have similar levels of improvement following a knee replacement, men have higher levels of function before.

According to research presented at the 2015 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), this difference could be the result of many factors, including genetic.

For the study, researchers looked at nearly 300 patients who were having a total knee replacement across seven institutions between 2005 and 2007. All but two of the patients had a diagnosis of end-stage arthritis and the group consisted of 108 men and 170 women, with a mean age of 67 and 66 respectively.

All participants were evaluated before their procedure, and then at six weeks, three months, one year, two years, five years and seven years after the surgery. During each assessment evaluation, researchers measured knee function, range of motion, extremity activity and overall health.

They found that, five years after surgery, implant survival was 100 per cent for men and 99.1 per cent for women, while range of motion was almost identical between the two sexes. However, functional scores were significantly higher for male participants. Men also recovered faster within the six week recovery time after surgery.
