Why Your Knees Hurt (And What You Can Do About It)

/ 1 Comments

If you’ve trained in martial arts (or any physical activity) long enough, you probably know someone with bad knees.  If you’re very unlucky, that person might be you.  In martial arts, a lot of people suffer from knee injuries that could have easily been avoided.  This is a guide for understanding, preventing, and managing knee injuries.

Types of Knee Injuries

Your knee is a more complex joint than it seems from the outside.  Superficially, it’s a hinge joint covered by a knee cap.  But if you look any closer than that, there’s quite a bit more going on there.  If you’re feeling pain, or even just oddness, in your knee, it could be a sign of something very serious.  Or it could be no big deal.

Despite the complexity of the joint, knee injuries fall into two general categories:  overload, and overuse.

Overload injuries come from a sudden force that pushes the knee beyond its function.  This can happen by an external force (falling or being struck), or by an internal force (a movement you initiated that caused the injury).  Overload injuries can happen to any athlete in any activity, even at the highest levels of performance.  They are sudden injuries that are very easy to notice.  If you’ve ever banged your knee into a coffee table, that was an overload injury.

Overuse injuries are a bit more insidious.  These occur when smaller forces act on the knee repeatedly.  By themselves, they are completely harmless when performed once or twice.  However, with a lot of repetition, they can cause serious and even permanent injuries.  Because they build up over time, it can be hard to figure out why your knees are hurting.  All you know is that some movement you are practicing is causing small incorrect pressure on your knees.  Because the problem is so subtle, it can be difficult to determine exactly what movement is causing the problem.  However, it is paramount that you figure it out, because if you continue to practice in the same way, the injury will only become worse. There are times when “work through the pain” is a valid mantra, but this isn’t one of them.  Don’t risk permanent damage to your knees just to prove you’re tough.

You will probably need to work closely with your instructor to identify the exact problem, but this article should give you a good starting point. These are the most common ways that martial artists end up with knee pain.

Incorrect Stances

If your knees hurt for no apparent reason, one of the first thing you’ll want to check is the way you are standing.  In taekwondo and karate, the biggest culprits are back stance and horse riding stance, because common mistakes in these stances can create incorrect pressure.

You want to make sure your knee is well supported by your tibia and fibula over your foot anytime you have weight on it.  This most often goes wrong when the knees “cave in” on back stance or horse riding stance.

When the knee and foot point in the same direction (left) it creates the proper structure and support. With the knee caved int (right) it puts dangerous pressure on the inside of the knee.

This is especially bad because not only does your structure lack support, but you’re also putting weight and pressure on the inside of the knee. Your knee is a hinge joint, so it doesn’t bend to the side.  Repeated pressure in that direction is one of the worst things you can do.

The camera angle isn’t ideal, but you can still see how the knees are over the feet in the correct version.

You still want good support even in the direction that your knee actually can bend.  Make sure your knees don’t bend by more than 90 degrees in any of your stances, and make sure your knee never extends past your toe on a load-bearing foot.  This can happen on any stance, but it happens most frequently on front stance.

Don’t let your knee extend past your toes.

Also check that your hips are situated comfortably in the same direction as your knees.  (And while you’re at it, check to make sure your spine is straight, as twisting or bending badly can cause overuse injuries in the back–but that’s a topic for another day.)

Notice how the pressure on the knees changes depending on the rotation of the hips and shoulders.

You can see in the first picture, the hips are twisted to put pressure on the inside of the back knee, where most of the weight is.  There’s also some unhealthy pressure on the outside of the front knee, but with less weight on that leg it is less noticeable and less damaging.  In the second picture, you have the opposite situation.  The pressure is on the inside of the front knee and the outside of the back knee.

Incorrect Pivoting When Kicking

I have ranted about the importance of correct pivoting on my other blog, but here I will focus on pivoting only as it pertains to knee injuries.  In short, it is extremely important for the standing leg to be in the right position when kicking.

There are many, many ways to throw a kick.  If you’re throwing a front kick, for example, you can throw the back leg or the front leg.  You can throw it from standing still, from a step, a skip, a jump, a fly, a slide, or a retreat.  You can throw it at a variety of heights.  You can make it a thrusting or swinging motion, a strike or a push.  You can optimize for speed, power, penetration or height.  And that’s to say nothing of the countless stylistic differences between arts, let alone any kick besides front kick.  It would be impossible to cover every pivot for every kick in an article like this, so instead I’ll lay out some guidelines.

First, there is an optimal standing foot position that will vary according to the kick you are doing, the subtleties how you are using it, and the stylistic details of your art.  Finding that correct standing foot position will not only be good for your joints, but it will also improve your balance and the effectiveness of the technique.  Pay close attention to your pivot, and work with your instructor to make sure you are doing it right.

Second, pay attention to the movement of your body weight and the position of your knee during the kick.  In particular, look for pressure on either side of your knee.  One very common example of this is pivoting too far on a rear leg front kick.  As your body weight shifts forward, your knee points perpendicular to your momentum, putting pressure on the inside of the knee.  (Not pivoting enough adversely affects your balance–again, work with your instructor to get it right!)

Notice the angle between the standing foot (and the facing of the knee) and the direction of momentum.

Another very common example is not pivoting enough on a roundhouse kick.  Not only does this make the kick very difficult to perform and take away a great deal of the power, you’re also putting a very problematic twisting pressure on your standing leg.  The knee is more fragile than your femur (above the knee) or your tibia and fibula (below the knee), so that is the point that will take the damage if you twist your standing leg.

roundhouse kick knee injuries

Not only is this angle bad for the knees, it also makes it very difficult to swing the leg correctly.

Correct Movements

Sometimes, “correct” technique can injure your knees.  This can happen for a lot of reasons.  For example, in many arts, large classes used to be unusual and instructors would teach individuals or small groups.  The training could be (and often was) individualized for the body type of the student.  This could affect the art in many ways, but for the purposes of knee injuries, techniques could (and should) be modified based on the hip structure of the student.  Without going into too much detail, the top of the femur and the socket part of the hip can vary greatly from person to person.  One student’s foot might naturally rest to the outside, another’s naturally resting to the inside.  Two students under the same master might have been taught a stance or a pivot differently based on body type alone.  When those two were experienced enough to start their own schools, they would pass on their art first exactly as they learned it–and this is why there are so many styles of the same art.  The point is, just because a movement is correct in your style does not mean that it is correct for your body.

This problem is amplified in America, a nation built by immigrants from all over the world.  The average martial arts class in America is likely to be far more ethnically diverse than the classes of the masters who created the arts we are learning.  In America, we are likely to see more variations in skeletal structure than the founders of our arts anticipated.  Even if a technique is correct in your style, adjust it if you must.  Trust your body.

Preexisting Injuries

Suppose you already have a knee injury.  Maybe it’s a overload injury, or maybe it’s an overuse injury.  You’ll probably need to see a doctor before you know for sure whether your injury can be healed or if it is permanent.  Either way, there should be things you can do to mitigate any knee pain.

For most knee injuries, moderate exercise will help with both the pain and the recovery (again, talk to your doctor for your specific situation).  So in most cases you should be able to continue your martial arts training.

By training correctly, you should become stronger, not weaker.  The goal of an unarmed martial art is to turn your body into a weapon.  What good is a weapon if it’s broken?  Practicing correctly should not harm your joints.  If your training is damaging your body, find out why and adjust your practice accordingly.

How to Counter an Arm Bar—A Self Defense Class at Martial Journeys of Madison

/ 0 Comments

One of the first classes I taught at Martial Journeys of Madison was a self defense class with a small group of fairly advanced students. After a warm up and a review of applying an arm bar after parrying a punch, I showed them three ways to counter it. (Obligatory disclaimer: Please do not try any of this without the aid of a knowledgeable instructor. An online article cannot convey everything you need to know to attempt this safely.)

Method 1: Spin out of it.

The first drill involved one partner throwing a punch so that the other partner could apply the arm bar. Once the arm bar was in place, the puncher twists away so that the locked arm ends behind the back but the other arm is free to strike the enemy.

ArmBarCounter1

Turning away to strike.

Method 2: Disrupt the angle.

The second drill is a little more difficult to apply because it must be done faster, before the partner can fully lock the arm. Step toward the opponent to keep your arm in front of you. Your free arm can strike the elbow to escape, allowing your formerly locked arm to strike for damage.

ArmBarCounter2

Turning into the enemy to disrupt the angle.

Pause for thought: Which method is better?

I asked the class which of these two methods was better. Traditionally, students of the martial arts are supposed to absorb, never asking questions, being as open as possible to everything they are told. There is value in this approach, but especially for more advanced students (as made up the class that day) critical thinking is important, too. I want my students to understand why, and not just how, a technique works.

For you online strangers who are not my students, I will just give you the answer rather than asking you to puzzle it out yourselves. Method 2 is better than Method 1. In Method 1, my opponent has control of my arm, leaving my movement restricted and taking away one of my weapons. I am literally fighting “with one hand behind my back.” In Method 2 I have all my weapons and more freedom of movement. You would use Method 1 only if you had to—if you reacted too late and the arm was already locked.

Method 3: Control the arm.

This method requires you to be even faster. As soon as the opponent makes contact with your arm (the initial parry that will lead to the arm bar), use your free hand to strike their elbow and disrupt their attempt–preferably before they even get a grip.  Use your punching hand to deliver a new strike.

ArmBarCounter3

Controlling the arm to prevent the lock.

Pause for thought: Now which method is better?

When I asked the class which was the better method between Method 2 and Method 3, there was a gem of a moment when my student was able to not only answer, but state it better than I would have. He said, “Method 3 is better because you never let them have any control over the fight.”

While that explanation is bordering on philosophical, it is absolutely correct from a practical perspective. Self defense is not a civil affair, where both sides take equal turns. If your life or well-being is threatened and you are forced to fight, the less control your opponent has over the exchange, the better your chances for survival.

Wrapping it all up

The students learned three ways to counter an arm bar, but that wasn’t the lesson. In practical self defense, your chances of needing to counter an arm bar are nearly zero. So why would I teach a class entirely devoted to countering an arm bar?

There are two reasons. First, by learning to counter a technique, you gain better mastery of that technique, by exploring its strengths and weaknesses and gaining a fuller understanding of how and why it works. But that wasn’t the lesson either.

I showed three ways to handle an arm bar, each a little more advantageous than the last, but each requiring a little more speed and control than the last. The speed and control allow you to end a fight more quickly, to spend less time in danger. So I gave the class one last question. What’s even better than Method 3?

This question was met with some sheepish glances around the room as everyone wondered if this was a trick question. It wasn’t, and while I knew that every single one of them knew the answer, we as martial artists should never let it slip out of sight and out of mind. So I was plenty happy when one of them said, “Not getting in a fight in the first place.”

From there we talked about dangerous situations that each student was most likely to encounter and how to avoid them, but that will be a topic for another article.

What are the Benefits of Taekwondo over Brazilian Jiujutsu for Self Defense?

/ 0 Comments

I once had someone interested in self defense ask me, “What are the benefits of taekwondo over BJJ?”  You could substitute any art names in there, such as, “What are the benefits of kung fu over MMA?” or “What are the benefits of tai chi over karate?”  It’s a very common question.  Common answers tend to go into lectures about strategy or techniques or even dubious statistics about how many fights go to the ground.

Any serious martial artist, when faced with a question like that, will be tempted to extol the virtues of their favorite style.  When I was asked about the benefits of taekwondo over BJJ, it certainly would have been easy for me to go on at length about how taekwondo seeks to end an altercation as early as possible, by striking before grips can be established, by constantly moving to keep striking options open.  In the case that the distance is closed and an attacker grabs hold, we teach escaping.  Fighting on the ground is taught for the very worst case scenario—when you have already failed in the earlier stages of the altercation.

It would be very easy for me to rant about that, but any such answer is going to be incomplete at best.  Violence, and therefore self defense, and even individual martial arts styles, are simply too broad a topic to be adequately addressed in those terms.

This was my answer instead.

The style of martial art you eventually go with shouldn’t matter.  I say “shouldn’t” because sometimes unfortunately it does matter.  I teach traditional taekwondo, so it’s a little different from what most people think of when they hear “taekwondo.”  Taekwondo is known for its kicking and other striking techniques, and some schools teach only that.  However if you really study taekwondo in depth, you’ll find a complete art that includes striking, joint locks, throws, and grappling.

It’s the same in most arts, including BJJ.  BJJ is known for its ground game, and certainly there are schools that only teach that.  But if you trace BJJ’s history through Japan, Japanese jiujitsu is also known for its ground work, but traditionally it also includes striking, joint locks and throws.  Like taekwondo, the paring down to a limited skill set is a modern invention.  A traditional school will likely have a broader curriculum.

With rare exceptions, any style can be a superficial summary or a complete art.  It depends entirely on the instructor and how they teach.  BJJ is a great choice.  Personally I prefer taekwondo, which is also a great choice.  But really, the best martial art is the one you train in—the one you get good at and learn to apply.

That’s why Martial Journeys of Madison allows people to try out taekwondo with a free class or intro evaluation—to see if this is the right art and the right school for you. Most reputable martial arts schools will do this. Some will welcome inquiries even if you are not looking to sign up. Obviously I can’t speak for any other school, but if you contact Martial Journeys of Madison for any reason, I’d love to hear from you.
