To stretch or not to stretch before a workout--that is the question many athletes ponder. A study finds that for runners, the pre-stretching versus not pre-stretching argument may be a 50/50 thing, neither doing any harm nor providing any benefits. The study, presented this week at the annual meeting of the American Academy of Orthopaedic Surgeons in San Diego, included 2,729 runners over the age of 13 who ran a minimum of 10 miles per week. About half were randomly assigned to do stretching just before running, and the others did no stretching.

Knee replacements last -- and last and last. We now know this thanks to a study presented Wednesday at the American Academy of Orthopaedic Surgeons annual meeting. But that doesn't mean the prospect of such an operation isn't scary. More than half a million Americans have knee replacement surgery each year. And it's the pain, either from arthritis, an injury or other cause, that spurs many to seek out surgery. This knee replacement tutorial from MedlinePlus can help dial back the fear factor.

Most athletic types would rather spend a month watching "Teletubbies" while reading Snooki's blog than suffer an injury. And when it comes to getting hurt, the knee is one of the worst things you can damage. The most commonly injured knee ligament is the anterior cruciate ligament in the middle of the joint. The ACL is responsible for keeping the knee stable by preventing the shin bone from sliding in front of the thigh bone. If torn, it usually requires surgical intervention, according to Dr. Robert Bray, an orthopedic surgeon at Calgary's Peter Lougheed Hospital.

How do I protect my knees and still maintain my marathon-training regimen? It's true; running can be tough on our knees. They bear the load of the rest of our body, serving as shock absorbers and soaking up the impact of several times our weight with every stride. Shoes, running surface, hills, weak muscles and over-pronation (feet rolling inward) can affect our knees' health; women may be more likely to have knee trouble than men.

Knee replacement surgery has become common in the last 30 years, and more younger people with bad knees are considering the surgery. A study presented Wednesday at the American Academy of Orthopaedic Surgeons annual meeting may reassure them that the replacement should hold up for a long time. Researchers evaluated 128 people who had lived at least 20 years after total knee replacement surgery. The patients' average age at the time of surgery was 63. The average age at the post-20-year follow-up was 82. The study found that almost all of the patients had good physical function.

They've packed on some fat, but maybe still no guilt. Those SnackWell's cookies that used to cause a run on stores whenever shelves were restocked now average 0.5 to 3.5 grams of fat; the crackers now average 1.5 grams. According to Ann Smith, spokeswoman for Nabisco, the snacks' maker, "When we showed people how much better the products could taste with just a gram or two of fat per serving, they were sold." And now, after a steady sales slump, perhaps the snacks will get sold.

Not everyone in Australia is consumed by the Olympics. The citizens of Walhalla--population 21--have declared their old gold-mining town an "Olympics-Free Zone." Visitors overheard gossiping about track times, sailing conditions, sports injuries or doping scandals will be fined on the spot. Unpatriotic? Not at all, said Rhonda Acquilina, who with husband Norm runs Walhalla's only general store in the outback town of western Victoria. "We're offering a haven for people who have had enough."

Debate about whether an artificial knee implant designed specifically for women has scientific merit continues a year after the device was launched, even as the orthopedics manufacturer racks up better-than-expected sales. Many orthopedic surgeons say Zimmer Holdings Inc.'s female knee is a marketing gimmick, but admit that they will implant them on request.

So much is moving to the Internet these days: shopping, television watching, coupon hunting. Here's one more: knee replacement rehab. A study published in the Jan. 19 issue of the Journal of Bone and Joint Surgery compared a live, Internet-based rehabilitation program to a traditional one for 65 men and women who had recent knee replacement surgery. About half of the patients were randomly assigned to an outpatient physical therapy program and acted as a control group. The others did rehabilitation via the Internet with real-time sessions with a physical therapist via video, following their instructions and learning how to care for their knees (for the study, the participants did the therapy in a hospital room designed to look like an average home)

Women considering a knee replacement might naturally think that a prosthesis designed specifically for the female body would be a better fit than a unisex product, leading to more favorable results, higher satisfaction and, overall, the most of what a new knee has to offer. That's not necessarily so. Researchers studied 85 women who had knee-replacement surgery in both legs. Such double surgeries were probably far from pleasant for study participants, but undeniably useful from a research prospective -- because all of the women received a standard prosthesis in one knee and a gender-specific prosthesis in the other knee.
