Is there any difference between results of knee replacement for men versus women? I’ve got a $10.00 bet riding on this one.

The answer is: yes and no. Whether you get the $10.00 may depend on how you placed your bet. A recent study followed patients across multiple centers in different countries. They report in each country, women were much worse before the surgery than the men. Women are more likely to delay the surgery. They get worse and worse before finally going in.

After surgery, men and women have equal outcomes in terms of pain and function. These findings remain the same when measured up to two years after surgery. This is true despite the big differences between men and women before the operation.
