I know that women are more prone to ACL injuries than men. Does this mean that women also have worse results from ACL surgery?

No. A recent study followed 200 patients who had ACL reconstruction. The researchers found that men and women actually had the same surgical results. There were a few minor physical differences, but in general women had the same amount of pain and physical function a few months after surgery as men did. And both groups were equally satisfied with their surgery. It seems that both men and women can expect good results from this kind of surgery.
