Patrick Willis undergoes knee surgery

The San Francisco 49ers have announced that linebacker Patrick Willis has undergone a “successful bursectomy” on his right knee.

The surgery was performed in Redwood City, California.

The term “bursectomy” means the removal of a bursa sac.  They typically are removed in the event of chronic inflammation (bursitis) or infection.

In 2008, Colts quarterback Peyton Manning had emergency surgery to remove an infected bursa sac.

Removal of the sac reduces the liquid that naturally lubricates the knee.  Given the position Willis plays, that could be a problem in the future.

UPDATE:  Matt Maiocco of the Santa Rosa Press Democrat reports that the procedure was performed last week, and that Willis is getting around on crutches.

SECOND UPDATE:  The 49ers have informed us that there was no infection involved.

  1. Let’s hope it’s not a problem for him. As a football fan who could care less about the 49ers, Willis is a stud. Easily one of the top defensive players in the league that is fun to watch.

  2. LOLLLLLLL
    “Removal of the sac”
    Thats a common procedure on that side of the Bay!
    Word is… The Tranny that 49er CB Eric Green sodomized had his/her sac removed too.
    Good luck Willis, having your sac removed, just dont bend over in the locker room with Eric Green standing behind you!

  3. You are a little off on your “knowledge sprinkle” there Florio. The synovial lining (or synovium)produces synovial fluid, and that is what lubricates the knee (or most joints). Bursa sacs generally provide a reduction in friction between bony prominences and tendons or muscles. Nevertheless, I agree with you. This could be a problem for one of the best linebackers in the game and his longevity.

  4. This isn’t going to be much of a problem for him for while he is young. When he hits mid thirties (getting up there for a LB) it will be tough, and when he is out of football he will be the guy in his 50s with the cane.
    Great player who plays the game like you wish every defensive player would.

  5. As a football fan u would know that the 9ers r moving n2 the right direction to at least win our division and make it to the playoffs. Onward to the Super Bowl, watch my words cp (cock puller)

  6. raiderrob21 is proof that one no longer needs to go to the store to find douche bags, you can find them online for free.

  7. I don’t think this will effect him as much as some people are saying..
    Hell i played for six years without an acl or any cartilage in my right knee…and I was a pasty, lazy, bigmouthed cover corner. I’m sure a proffesional asskicker like Willis can go another 10 seasons without a bursa sac.

  8. The San Francisco 49ers have announced that linebacker Patrick Willis has undergone a rectum renovation.
    The surgery was performed in a bath house in San Francisco.

  9. Why do raider fans constantly feel the need to comment on Niner posts?… I mean if you’re going to make a joke about the niners can it at least be funny?

  10. let me give you guys a little story while i wait for the old lady to come home and take care of me….ready? i have owned 5 jap cycles in my life. the first i bought when i was twenty. i took it to a shop to have an exhaust put on and the old sage mechanic said to me “why do you want to take off the stuff they engineered the bike to do”? it ran like shit after i had it done. the lesson is they put them parts in for a reason. removing them is never a good thing. he is gonna pay for it in years to come even though he will be very rich.

  11. Pinkie 49er Commie,
    I know on your side of the Bay, your little Commies like to suppress the truth, but on this forum, you have no power.
    Mrs. Pelosi and Gavie, don’t run this site.
    Please get your garbage franchise out of the Bay Area.
    L.A.’s calling.
    PS,
    Your Pink Franchise will never play in our venue.
