Want to avoid surgery? Take care of your joints.
AS much as Dr Sean Haslam loves performing surgery, he certainly wouldn’t object if people would take good enough care of themselves to avoid – or at least postpone – it.
“Anytime we can get something to help patients without surgery,” says the orthopaedic surgeon, “it’s good for everybody.”
But people don’t seem to be paying attention. In the US, the number of knee replacements is up 165% in the last two decades and, according to the Journal Of The American Medical Association, could exceed 3.5 million by 2030.
Why pay attention to your knees, hips, shoulders and other joints?
First, doing so could keep you out of the operating room. Second, when your joints don’t hurt, you’re going to feel better physically and mentally. Plus, you’re better able to stand up, sit down, move around and do any number of ordinary tasks with the most minimal of groans and bodily creaks.
“The main reason for total knee replacement is for pain,” Dr Haslam says. “If we can get rid of the pain, we can get rid of the real need to have surgery.”
The keys to joint health for most people are, no surprise, losing weight and exercising. Some dramatic cases in point:
In a Canadian study, none of 125 obese knee-replacement candidates who lost 10% of their body weight went on to have the surgery, says Dr Haslam, who was part of the research team.
About half who dropped out of the study, which he stresses isn’t yet published, lost “a significant amount” of weight and also opted not to have their knees replaced.
Because six to eight times your body weight is experienced through the knee, every 10 pounds lost means 60 to 80 pounds less pressure, he says. Plus, additional weight can lead to a greater risk in developing arthritis and a likelihood that mild osteoarthritis you might already have will worsen.
At the T. Boone Pickens YMCA in Dallas, trainer Shane McLean has clients who have “not great knees” and “not great shoulders”, he says. “They’re usually overweight.”
The obvious solution to joint health is to lose weight. But, says Dr Haslam, “it’s a vicious cycle. The formula is simple; the execution is difficult.”
Patients tell him they can’t lose weight because they can’t work out, and they can’t work out because it hurts. The less you move, though, the stiffer you get. And the stiffer you get, the more you’ll hurt when you start moving.
But inactivity leads to loss in cartilage, which “allows some slide”, between your bones, Dr Haslam says. Without cartilage, you have scraping of bone on bone, which is as painful as it sounds.
Losing weight won’t replace cartilage; what’s done is done. But it will make for less stress on joints.
Exercise also helps because it stimulates the release of synovial fluid. Think of the Tin Man and how a few squirts of oil helped loosen his joints and get him moving.
The more you move your joints, the more a release of synovial fluid you have, Dr Haslam says. “It bathes the cartilage.”
That’s important because cartilage doesn’t have a blood supply. Instead, it depends on the fluid to provide nutrients.
Proper exercise technique is essential for healthy joints, successful workouts and weight loss, says McLean.
He has three herniated discs in his own back, so he empathizes with the many people who have pain.
“There are various things I do to work around the problem,” McLean says. “Just because you have a bad back or bad knees, I believe there’s something you can do.”
Poor posture causes many of the joint issues he sees.
“People are hunched over,” he says. “Shoulder problems usually stem from posture issues and incorrect weightlifting technique. When you have a hunched back and your upper body isn’t underneath your hips, chronic conditions start to happen. It won’t hurt today or tomorrow, but somewhere down the line it will.”
Randi Schwartz, 52, says during the years she was running regularly, she ignored signs that something was amiss in her body. Not until her hip started roaring did she pay attention.
“I had whispers, and I kept running right through it,” says Schwartz. “Big-time yoga – right on through it.”
Several years of discomfort eventually led to hip replacement surgery recently. She no longer runs but walks for exercise. She’s also built up her technique and stamina to swim – an excellent exercise for joints – for more than 3km without stopping. But the journey has been tough.
“This I did to myself,” says Schwartz, who works in retail couture. “All those years of running and pounding and not listening.”
Running isn’t inherently bad for joints. A recent study published by the US National Center for Biotechnology Information found that running “significantly reduced” the incidence of osteoarthritis and risk of hip replacements. One reason seems to be that runners have a lower body mass index.
In general, though, Dr Haslam cautions that running and other higher-impact sports such as basketball and tennis are better started when a person is young. As you age and lose bone mass, your body calls upon the bone mass you’ve already banked, he says. Starting it later can cause more pain.
“My rule of thumb is that if you’re not having pain, go ahead,” Haslam says. “But if you start to develop arthritis and have pain every time you’re 300 yards out and it gets worse, you may want to switch exercise.”
He and McLean emphasize low-impact workouts such as specific classes, the elliptical trainer, a recumbent bicycle, walking and swimming – anything that maintains cardiovascular benefits without loading the joints.
“If you can only walk five minutes a day, walk five minutes a day,” McLean says.
Dr Haslam likens having stiff joints to wearing a coat that’s too tight. You feel increased pressure and can’t move well. Simple motions are difficult and painful. He offers these tips for easing or eliminating that discomfort.
Think range of motion – The more range of motion you have, he says, “the more limber and less stiff you are.” So stretch daily. Reach behind your head like you’re fixing your hair, and behind your back like you’re zipping a dress. Fully extend and fully bend your knees regularly.
Sit on an exercise ball – Moving around or standing is preferable to sitting, but not always feasible. So sit on an exercise ball while you watch TV or at your desk. “You’re working your core, and that’s great for your back,” he says.
Consider supplements – Gluco-samine and chondroitin have beneficial effects on osteoarthritis, which is often due to loss of cartilage between bones. Plus, if you take calcium, make sure it has vitamin D. Without that, “calcium won’t get into the bone”, he says. – The Dallas Morning News/McClatchy-Tribune Information Services
