Weight
management techniques
The aforementioned key to keeping a knee problem at bay is to stay
relatively active and eat right. Current research shows that 56% of
Americans are overweight, and 25% are classified as obese. This is
bad news for our knees.
Let's talk BMI, or body mass index. BMI
is the number you come up with when you divide how much you weigh in
kilograms by how tall you are in centimeters squared. A BMI between
18.5 and 25 is considered normal. A BMI above 25 is considered overweight,
and a BMI of 30 or more is classified as obesity. To find your BMI,
there are several calculators on the Internet including the BMI
recommendations from the Surgeon General.

Diet
Losing weight can provide some instant relief for the knees. Although
we are constantly inundated with new diet fads, remember that logically,
the way to lose weight is to consume fewer calories than we burn,
and the way to maintain weight is to take in approximately the same
number of calories that we burn. This method can be harder to follow
than it is to understand, and once we build healthy habits, this
lifestyle will become easier and easier to maintain. Some diets help
you to do this. Others are shams. Be cautious. Anything that seems
too good to be true probably is.
If you have arthritis, there are pain
aggravators that should be avoided. For instance, paprika, pepper,
tobacco, cayenne, eggplant and large amounts of potatoes and tomatoes
can antagonize your arthritis since these foods have alkaloids that
prevent the repair of collagen and cartilage. Aspartame (found in diet
sodas and artificial sweeteners) can also worsen arthritis, since it
can cause inflammation in the joints when regularly consumed.
There are health benefits from eating
a diet rich in fiber and complex carbohydrates found in vegetables,
whole wheat and fruits. Once again, knees also benefit from this diet.

Exercise
It is also important to incorporate exercise into your routine if you
have knee pain. Although it may seem like a catch-22 (you can't exercise
because your knee hurts, but your knee hurts more because you can't
exercise), strengthening the leg muscles can be crucial in alleviating
knee pain. The more support the muscles can offer, the less stress
and pain you will encounter. Please refer to our online exercise
library, which will show you several knee strengthening exercises.
Also, if your knee hurts and you want to start up an exercise routine,
why not try a stationary bike or swimming? While running or stair
climbing can be taxing to the knees, the stationary bike and swimming
are both excellent cardiovascular activities that only place minimal
pressure on the knees.

Looking
before you leap and other ways to prevent knee injuries
It is ironic that while movement can cause knee pain, movement can
also prevent and alleviate knee pain. By bending and stretching, the
muscles are lubricated and perform better. Exercise also helps us stay
in shape and at a healthy weight keeping the knees strong. Below, we
have listed techniques you can use to prevent an injury related to
various sports categories.
Snow skiing
With ski injuries accounting for 137,000 emergency room visits a year
(and 34 deaths), it's important to take preventive measures before
hitting the slopes to make sure you don't become part of the statistic.
The key thing to remember is bindings, bindings, bindings. Proper
bindings will improve your performance and stability while easing
up on your knees. Not only is it important to have the right binding,
but the way it is adjusted is crucial as well. Beginner skiers should
have a looser bind, while more advanced skiers may have more secure
bindings that relate to the aggressive terrain they ski. There have
been dramatic technological changes in the past few years, making
bindings older than a couple of years obsolete.
To build your endurance, start preparing
three months in advance. Build up your cardiovascular strength, since
mountain air is thinner, making it more taxing to breathe. And, if
you get tuckered out, chances are you may become more sloppy and prone
to injury.
Statistics have also shown that, traditionally,
snowboarders have fewer knee injuries than skiers. (Snowboarders, conversely,
have lots of wrist injuries.) So snowboarding might double as a fun
alternative to skiing if you have knee problems.
Below are the skier's responsibility
code designed to prevent accidents before they happen as outlined by
the National Ski Areas Association:
- Always stay in control, and
be able to stop and avoid other people or objects.
- People ahead of you have the
right of way. It is your responsibility to avoid them.
- You must not stop where you
obstruct a trail, or where you are not visible from above.
- Whenever starting downhill or
merging into a trail, look uphill and yield to others.
- Observe all posted signs and
warnings. Keep off closed trails and out of closed areas.
- Prior to using a lift, you must
have the knowledge and ability to load, ride, and unload safely.
Water skiing
For water skiers, knee pain can stem from the vibration of the water
underneath the ski. Just as with snow skiing, the right binding is
crucial for preventing injury. Depending on what you want to do on
the water, there are different bindings to use. Generally, a slalom
skier will want to have a lot of ankle support, which in turn will
support the knee when cutting across the wake.
A few months before water ski season,
begin working out to prepare yourself. For instance, stretching out
your muscles daily and improving cardiovascular performance will not
only help you ski stronger and harder, it can help prevent injury.
When lifting weights, an all over tone is important, but focus on key
muscles that may not normally be utilized such as the forearms, and
trapezoids. If you have a strong upper balance as you cross over the
wake, your knees won't have to bear all of the brunt of the impact.
For those who use two skis, be careful and if possible, you may want
to learn how to slalom.
Wakeboarding
After dramatically increasing in popularity over the past few years,
wakeboarding certainly deserves an honorable mention in this section.
In preventing knee pain, the binding is the most crucial part of
wakeboarding. The way you board will determine the type of binding,
how tight it is and at what angle it is put on the board. There can
be a lot of unnatural knee twisting and strain, especially for beginners.
To be prepared, build up your calf muscle strength and flexibility.
Also, arm strength is imperative to prevent knee injuries.
Basketball
Basketball can be damaging to the knees, not so much from running up
and down the court as from landing in an uncomfortable way. So, weekend
warriors, to avoid sprains and tears, try playing less aggressively.
Football
Football and other impact sports are highly dangerous to the knees,—
especially if you are on offense and the one being tackled. Most tackles
are directed AT the knees with impacts from all sides. Worse, there
is not much you can do to prevent injury, as hard side impacts will
damage any knee.
Soccer
Although, this sport is not as popular in the United States as it is
in other parts of the world, it is important to mention. Soccer is
great in that it works the cardiovascular system very hard. While
soccer players are not being tackled, the knees do take abuse from
constant running, stopping, abrupt turning and kicking. ACL and meniscus
tears are common.
Golf
Golf can be a great way to keep the knees strong, especially if you
forgo the golf cart and walk the course. To lighten your bag, try
to carry fewer clubs. Even if you use them all, there are some that
you might not hit as well with, such as the 2-iron, the 3-iron or
the 4-iron. Sometimes, knee pain may be caused by a poor swing. If
your knees hurt after playing golf, talk to a golf pro who can show
you ways to swing that lessen the role of your knees in your swing.

Tennis
Tennis can also be hard on your knees with the sudden changes in direction
required by aggressive play—especially in singles tennis. Recreational
doubles tennis, on the other hand, can be great exercise and less
risky to your knees.
Running
Running can be quite hard on the meniscus pads in the knees, especially
when running long distances. After a while, the shock-absorbing meniscus
pads wear out and tear. This is particularly true of those who are
overweight.
Walking
Walking can be a great form of cardiovascular exercise and is relatively
easy on the knees. A brief walk for 30 minutes can push you as hard
as it would a jogger and with less pressure to the knees.
Biking
Also better for the knees, biking can be a great cardiovascular activity.
To prevent biking injuries, try to increase your range of motion beforehand.
You can do this by lying on your back, putting your feet in the air
and pedaling. This will increase your range of motion without the pressure
of your body weight.
Swimming
Swimming is a great cardiovascular exercise that is also harmless to
the knees (with the exception of those who have kneecap pain or patellar
tendinitis). It puts almost no pressure on your knees, and you can
push yourself aerobically as hard as you can handle.

The
right equipment will help prevent injury
Shoes
If you run a lot, buy great shoes. Shoes that cost $150 are a small
price to pay, since the alternative could cost you more, and the
pain simply isn't worth it. Basically, buy the best shoes for whatever
sport you are doing. Try to find a store with someone who will
watch you on a treadmill and offer recommendations. Are you a pronater?
A supinater? Finding this out will help you find shoes that compensate
for any instability, thus alleviating potential stress on your
knees. Shoes can be deceptive. Don't buy a shoe because it looks
stylish. Purchase for function rather than fashion.
Knee braces
Knee braces serve different purposes. Some improve your kneecap stability,
while others prevent lateral movement in the knee. Overall, the
knee brace mostly supports only a side-to-side movement as opposed
to a rotational movement. Mentally, the knee brace serves as a
reminder that the knee is not fully healed and to be careful not
to hurt it further.
On the flip side, while the brace certainly provides
support, it can also act as a crutch, which can prevent the leg from
strengthening crucial muscles. Long term, the goal is to make the
knee strong enough to work without artificial support.
Certain types of braces are needed for specific injuries.
For ACL tears that are treated without surgery, a 'derotation' brace
customized for the individual should be used. For kneecap stability,
a special brace needs to be used. Also, for the arthritic knee, a
basic Neoprene brace can be helpful. Be sure to consult a physician
to find out what type of brace (if one is needed at all) you should
use.
Knee pads
Over the past, decade roller blades have become quite popular. Kids
are constantly trying to improve on a jump or learn a new trick.
To stay safe, it is important to wear knee pads in addition to
a helmet for overall protection from falls. Although not as "fashionable,"
knee pads could help prevent a serious injury such as breaking the
knee cap during a hard fall.
