Actually, his 4th knee operation. This is an article from the
NYTimes that's a little more detailed than most of what I've read, and it says what you say, Margaret, that that cartiledge/meniscus procedure takes time to heal from. It says that he'll probably start practicing tennis again in March or April. (I realize that article maybe behind a pay wall, so I'm summarizing a bit.) He also doesn't really think that 40 or 41 makes much of a difference, but the IF he can come back and compete on his terms. It is sounding a bit harsh, but if anyone can give it one more go, I'm sure Roger will.
