This happens all the time with athletes. They opt for surgery right before the start of the new season, even though that ailment was with them the entire offseason.

Dirk Nowitzki had surgery on his knee today and will be out six weeks.

This is the same knee that we have been talking about all summer long. Why this didn’t happen before is beyond me? Him missing part of the regular season probably could’ve been avoided. The knee bothered him last season too.
