Teen bond overcomes girl's heart transplant fear (AP)

WASHINGTON � Courtney Montgomery's heart was failing fast, but the 16-year-old furiously refused when her doctors, and her mother, urged a transplant.

Previous surgeries hadn't helped and the North Carolina girl didn't believe this scarier operation would either. It would take another teen who's thriving with a new heart to change her mind.

"I was like, `No, I don't want this. If I'm going to die, I'm going to die,'" Courtney recalls. "Now I look back, I realize I wasn't thinking the way I should have been."

Teenagers can add complex psychology to organ transplantation: Even though they're minors, they need to be on board with a transplant because it's up to them to take care of their new organ. Depression, anger and normal adolescent pangs � that tug-of-war with parents, trying to fit in � can interfere. It's not just a question of having the transplant, but how motivated they are to stick with anti-rejection treatment for years to come.

"The decision-making process that we go through, in terms of our ability to weigh factors in a rational sense, probably doesn't mature until you're in your late 20s," says Dr. Robert Jaquiss, pediatric heart surgery chief at Duke University Medical Center, where Courtney eventually was transplanted. "It introduces an enormous level of complexity to caring for these kids."

Then there's the sense of isolation. Far fewer adolescents than older adults undergo an organ transplant, making it unlikely that a teen has ever seen how fast their peers can bounce back.

Between 700 and 800 adolescents, ages 11 to 17, have some type of organ transplant each year. That's nearly 40 percent of the roughly 2,000 annual pediatric transplants. Teens fare better than any other age � child or adult � the first year after surgery. But long-term, adolescents do a bit worse than younger children, and the reason isn't biological, Jaquiss says. It's that teens, and young adults as well, tend to start slipping on all the required follow-up care.

One study found up to 40 percent of adolescent liver recipients eventually miss medication doses or checkups. It can be normal development, as teens start sleeping late and simply forgetting morning doses, or sometimes it's rebelliousness. Then there are medication side effects that Jaquiss says can be especially troubling to this image-conscious age group: weight gain, acne and unwanted hair growth.

And at the Children's Hospital of Pittsburgh, separate research with heart recipients has found chronological age is unrelated to "medical maturity." Young patients who had a hard time accepting a transplant as normal and who avoided family discussion of problems, for example, were less likely to stick with care.

Courtney's mother, Michelle Mescall, said that when the medical center advised that her daughter needed to agree to go on the transplant waiting list, "I said, `Well she's a minor, what do you mean? I'm going to make this decision.' I was just floored that it was now her decision."

Legally, the hospital could have proceeded with mom's OK. But clinical social worker Shani Foy-Watson says if that happened, Courtney's resentment could have torpedoed her recovery, setting up just those kinds of problems with follow-up care.

Foy-Watson says it's not unusual for kids who've lived with serious illness for years to have a hard time imagining normalcy � at the same age when it's normal to seek more independence from their terrified parents.

Courtney, of Asheville, N.C., was diagnosed at age 8 with hypertrophic cardiomyopathy, a thickened and hard-to-pump heart that's the leading cause of sudden death in young athletes. Her mother tried to shield her from doctors' death warnings, but says Courtney became anxious and depressed early on.

She had a defibrillator implanted and later heart surgery that offered only temporary relief, fueling resentment of her mother's medical choices. Courtney eventually had to give up her beloved cheerleading, and last year required home-schooling.

As a few weeks passed with Courtney still resisting a transplant, the social worker tried a new tack: A 17-year-old football player had received a new heart at Duke a few months earlier because of the same condition, and already was back at school in Raleigh. Would he meet with Courtney?

It was a gamble. No one told Josh Winstead, now 18, the reason for the meeting, and they might not have hit it off. But they did, and Courtney immediately changed her mind.

"I guess me doing what I do, being a kid, helped out the most," says Winstead, who took Courtney to his prom a week before her surgery. "It was more just showing her how normal my life is."

You hear all the advice from friends and doctors, Courtney says, "but it doesn't hit home like when Josh would tell me, `I have the same scars you do and this is how it felt and this is how I feel now.'"

She got her new heart last month. She's recovering well and exercising in hopes of getting back to the cheerleading squad.

Her mother's helping Courtney learn to handle a whopping 33 pills a day, and is proud of how her daughter has rallied: "I'm just dealing with how to let go and let her fly, but also be the parent of a 16-year-old."

Baby boomers fueling boom in knee, hip surgeries (AP)

SAN DIEGO � We're becoming a nation of bum knees, worn-out hips and sore shoulders, and it's not just the Medicare set. Baby boomer bones and joints also are taking a pounding, spawning a boom in operations to fix them.

Knee replacement surgeries have doubled over the last decade and more than tripled in the 45-to-64 age group, new research shows. Hips are trending that way, too.

And here's a surprise: It's not all due to obesity. Ironically, trying to stay fit and avoid extra pounds is taking a toll on a generation that expects bad joints can be swapped out like old tires on a car.

"Boomeritis" or "fix-me-itis" is what Dr. Nicholas DiNubile, a suburban Philadelphia surgeon, calls it.

"It's this mindset of `fix me at any cost, turn back the clock,'" said DiNubile, an adviser to several pro athletic groups and a spokesman for the American Academy of Orthopaedic Surgeons. "The boomers are the first generation trying to stay active in droves on an aging frame" and are less willing to use a cane or put up with pain or stiffness as their grandparents did, he said.

A huge industry says they don't have to. TV ads show people water skiing with new hips. Ads tout "the athletic knee," "the custom knee," "the male knee," "the female knee." Tennis great Billie Jean King, 67, is promoting the "30-year" Smith & Nephew knees she got last year.

"I wanted to make sure whatever they put in me was going to last," she said. "I'm not trying to win Wimbledon anymore. I'm trying to get my exercise in," play a little tennis on the clay courts in Central Park, and walk to a movie or a restaurant. "If I'd known what I know now, I would have had it 10 years ago."

Joint replacements have enabled millions of people like King to lead better lives, and surgeons are increasingly comfortable offering them to younger people.

But here's the rub: No one really knows how well these implants will perform in the active baby boomers getting them now. Most studies were done in older folks whose expectations were to be able to go watch a grandchild's soccer game � not play the sport themselves, as one researcher put it.

Even the studies presented at a recent orthopedics conference that found knee replacements are lasting 20 years come with the caveat that this is in older people who were not stressing their new joints by running marathons, skiing or playing tennis.

Besides the usual risks of surgery � infection, blood clots, anesthesia problems � replacing joints in younger people increases the odds they'll need future operations when these wear out, specialists say.

"We think very carefully about patients under 50" and talk many of them out of replacing joints, said Dr. William Robb, orthopedics chief at NorthShore University HealthSystem in suburban Chicago.

But many don't want to wait, even if they're not much beyond that:

_Karen Guffey, a 55-year-old retired civilian police worker in San Diego, plans to have a hip replaced in September. "I can't exercise the way I want to. I have to go slow, which is really aggravating. I want to go full force," she said. "I'm not worried about how I'm going to feel when I'm 75. I want to feel good now."

_Karen Cornwall, a Havertown, Pa., nurse who played a slew of sports since childhood, had both knees replaced last year when she was 54. "I just felt like I was too young and too active to be in pain all the time," she explained.

_Bill McMullen, a former Marine and construction worker from suburban Philadelphia, had seven knee repair surgeries before finally getting a knee replacement at age 55 a decade ago. He took up weightlifting to spare his knees but damaged a shoulder and had it replaced two years ago. "People ask me if I'm happy and I say, `If you have pain, go and get it done,'" he said of joint replacement. "It was the best thing for me. I have no pain."

People are urged to exercise because it's so important for health, but there are "too many wannabes" who overdo it by trying to imitate elite athletes, said Dr. Norman Schachar, a surgeon and assistant dean at the University of Calgary in Alberta, Canada.

"They think if they've got a sore knee they're entitled to having it replaced," he said. "I think surgeons are overdoing it too, to try to meet that expectation."

Dr. Ronald Hillock, an orthopedic surgeon in a large practice in Las Vegas that does about 4,000 joint replacements a year, sees the demand from patients.

"People come in and say `this is what I want, this is what I need,'" he said. "They could buy a cane or wear a brace," but most want a surgical fix.

The numbers tell the story. There were 288,471 total hip replacements in 2009, nearly half of them in people under 65, according to the federal Agency for Healthcare Research and Quality, which tracks hospitalizations.

Knee replacements soared from 264,311 in 1997 to 621,029 in 2009, and more than tripled in the 45-to-64-year-old age group.

"Five or 10 years ago, a very small number of people under 65 were receiving this surgery. Now we see more and more younger people getting it," said Elena Losina, co-director of the Orthopaedic and Arthritis Center for Outcomes Research at Brigham and Women's Hospital in Boston.

She analyzed how much of this rise was due to population growth and obesity, and presented results at an orthopedic meeting in San Diego in February.

From 1997 to 2007, the population of 45- to 64-year-olds grew by 36 percent, but knee replacements in this group more than tripled. Obesity rates didn't rise enough to explain the trend.

"At most, 23 percent of the 10-year growth in total knee replacement can be explained by increasing obesity and population size," Losina said.

"This is a very successful operation. The only caveat is, all the successes have been seen in the older population," who usually put less stress on their new joints than younger folks who want to return to sports. "It's unclear whether the artificial joint is designed to withstand this higher activity," she said.

If you have a good result from a joint replacement, don't spoil it by overdoing the activity afterward, experts warn. Better yet, try to prevent the need for one.

"Being active is the closest thing to the fountain of youth," but most people need to modify their exercise habits because they're overdoing one sport, not stretching, or doing something else that puts their joints at risk, said DiNubile, the "boomeritis" doctor.

Experts recommend:

_Cross training. People tend to find one thing they like and do it a lot, but multiple activities prevent overuse.

_Balance your routines to build strength, flexibility, core muscles and cardiovascular health.

_Lose weight. "Every extra pound you carry registers as five extra pounds on your knees," DiNubile said. "The good news is, you don't need to lose a lot of weight" to ease the burden.

_Spend more time warming up. Break a sweat and get the blood flowing before you go full blast.

_Let muscles and joints recover and rest in between workouts.

_If you've had a joint replacement, do the physical therapy that's recommended.

"I tell patients, 20 percent of the outcome is the technical stuff I do in the surgery, and 80 percent is them," said Hillock, the Las Vegas surgeon. "I can do a perfect surgery, but if they don't do the rehab they're not going to have a good outcome."
