Ask A Physio: If My Knee Hurts, Why Are You Looking At My Hip?

As physios, we see bodies differently than most people. This is a good thing - you want your body specialist to see beyond the obvious! But what is often obvious to us is a mystery to others.

You may have heard one of us talking about the “kinetic chain”, a concept borrowed from the engineering world and repackaged for health care. The basic idea is the movement in one joint will create and affect the movement of the next joint, and so on. If your pain is in your elbow, we would be doing you a disservice if we didn’t also look at your wrist, shoulder, neck and upper back as well.

The kinetic chain is a big reason why one-size-fits-all approaches don’t work.

We don’t tell you to simply Google your symptoms and treat yourself. One person’s treatment approach for sciatica will be completely different than the next. My grandma’s elbow pain often has a completely different cause than my daughter’s elbow pain, even if they are in the same spot. Looking at the body as a whole is imperative to proper treatment.

A Case Study in Kinetic Chains: Runner’s Knee

A great example of this is someone with runner’s knee, also known as patellofemoral syndrome (PFPS). To understand how PFPS develops, an understanding of knee biomechanics is crucial.

The patella (aka the kneecap) rides in a groove on the femur at the front of the knee and is critical for proper knee movement. The patella acts as the attachment point for ALL your quads - think of how much muscle that is! To stretch out your leg, your quads first contract and pull on the patella. The force is transmitted through the patellar tendon (or ligament, depending on who you read) and pulls on the tibia, the main bone of your lower leg. Without the patella, the amount of force required for the quads to unbend the knee is simply too great. The patella acts as a fulcrum, giving the quads a mechanical advantage.

Muscle imbalance is one of the main causes of PFPS. The patella is held in its position by a fine balance of muscle and connective tissue. Muscles that attach to the patella directly - we’re talking about the quads here - are obviously a main focus. But there’s many more muscles to consider. Consider these two examples:

1. One cause of PFPS is tight calf muscles. The gastrocnemius, one of the calf muscles, attaches at the back of the leg above the knee and can have a great effect on knee function. When these muscles are too tight, people tend to walk more in a pronated foot position (see photo on the right), increasing the forces at the back of the knee and adding to the compression and irritation of tissues around the patella.

2. The IT band runs the length of the thigh on the outside of the leg and attaches to the outside of the patella. The gluteus maximus, the large muscle in your buttock that controls hip extension, attaches into the top of the IT band. If the glutes aren’t doing their job, you can experience knee pain even if it isn’t the source of the problem.

We don’t expect you to know the ins and outs of this - that’s our job! When you come in for a little rehab, don’t be surprised when we start checking out your other joints - you may be surprised by what we find.

Ask A Physio - Why Is My Joint Making That Noise?

Joints can make peculiar noises. They can snap, pop, crack, grind, grate, click and clunk. The proper name for these noises is crepitus. Many people become understandably nervous about this, especially if it is a “new noise.” Although crepitus is generally unwelcome, it is not as scary as you think.

When people come to physiotherapy for joint noises they generally have similar concerns. They want to know what is causing the noise and how to stop it.

The general perception people have is their joint must now be degenerated and “bone on bone.” People take this as a sign of aging and extreme arthritis and become scared for their joints. They do not want to unnecessarily wear the joints down.

So what do they do? They avoid the noise! They stop climbing stairs and getting down on the ground to play with their kids and grandkids. They tell me they have stopped doing the movement that initiates the noise in order to “preserve” the joint or avoid “making it worse.”

It seems logical right? If I rotate my neck to the right and it snaps or clicks I may feel unsettled by that and want to avoid that feeling. I hear constantly from my clients that they don’t swim anymore because their shoulder clicks when they bring their arm over their head, or they no longer squat because their knees click on the way down.

My response to these clients is always the same - I ask:

“Does it hurt when it clicks?” 

Because here is the thing. There are many causes for crepitus. And yes, some of them require treatment, but many do not! Before anything else, we need to figure out what is causing the clicking and decide if we have to be concerned about it or not.

Most snaps, crackles and pops are pain free and totally harmless.

If you do not experience pain when your joint makes a noise you don’t have to worry about it and can continue with business as usual. 

Common Causes of Crepitus

• The most common culprit is gas bubbles popping within the joint (think cracking knuckles). When the joint is stretched and released a gas bubble is formed and then pops, causing the noise.

• The crepitus could also be a tendon or ligament snapping over a bony structure. In this case there might be pain, but it has nothing to do with the joint and a whole lot more with the muscle. This would require an assessment, range of motion and strength exercises from a physiotherapist.  

• Arthritis. Yes, sometimes crepitus is because of arthritis.  But please know that the clicking or grinding does not mean you are doing “extra damage” to the joint. If you have arthritis a primary goal is to maintain range of motion. Working through your available range should be a priority rather than being avoided. If your knees are a little extra talkative but you have no pain and no decrease in function I would encourage you to continue with your activities. There are so many benefits to exercise (cardiovascular, mental, general strength, etc.) and it would be a shame to throw all of those away because of a misconception that you had about your click-y knee. 

Speaking of Knees…

Most noisy joints I see people for happen to be knees. If you’re wondering what that noise is and what’s causing it, here’s our top three noises people complain of and what they could mean (please be aware that this is a gross generalization but is meant to give you a decent idea):

1. Snapping, cracking or clicking “outside” of your knee: This is often due to the patellofemoral joint. The patella (aka kneecap) lives in a little groove that it is supposed to glide up and down in when your knee bends and straightens. If the patella is not properly aligned (maybe from an injury or muscle imbalance) it can make noise as you crouch, use the stairs, or just with bending and straightening your knee. If these noises are inconsistent, occasional, and pain-free I would not worry. If they are constant and painful then seeing a physiotherapist can be very helpful.

2. Snapping, cracking, or clicking “inside of your knee”: This is often your meniscus, which is the cartilage shock absorber within the joint. With injury or degeneration over time this structure can tear, rip or peel back. In some cases a flap of cartilage can get caught out of place and this will often cause the joint to “lock.” If you have a click within your knee that causes a sharp pain and sometimes causes the joint to lock it is likely a meniscus problem and you should visit a physiotherapist. 

3. Creaking or grinding: This is most often associated with arthritis. If it is early stages and you are noticing some pain it is definitely worth a trip to your neighbourhood physiotherapist as an arthritis management plan can significantly impact the maintenance of range of motion, strength and function in the joint. (Side note - since exercise is one of the best ways to manage osteoarthritis, we offer the GLA:D Program!)

Again, if you experience these noises and there is no pain then I would not be too worried about it. But if you have these noises and they are painful it is probably worth coming in to see a physiotherapist. We will assess your joint range of motion, muscle strength and balance, and see if we can identify the cause for the click so we can come up with a treatment plan that will work for you. 

If the noise bothers you enough that you cannot stop worrying about, come on in. If nothing else we can confirm to you that it is harmless and you can have peace of mind moving forward with your activities. We are always happy to help!

Ask A Physio: How Can I Get Rid Of My Sciatica?

We’ve all heard of sciatica - that awful, weird pain that runs down the back of your leg. It’s often fairly vague pain and hard to pinpoint but there’s no mistaking its presence.

Lately, we have seen a serious uptick in clients complaining of sciatica and its good friend, low back pain. So, what is sciatica and what exactly can we do about it?

What Is Sciatica?

Sciatica refers to in irritation of the sciatic nerve which runs down the back side of your leg and innervates the hamstrings and all the muscles below the knee. The sciatic nerve is HUGE - about the width of your thumb! It passes through, around and beside some major structures including the spine as well as the glutes and piriformis in the buttocks.

The classic profile of someone with sciatic-related pain can include:

• Pain in the low back that radiates down the back of the leg, described as anything from dull and achy to sharp, burning or electrical

• Tingling and/or numbness in the lower spine, buttock, back of thigh, calf and/or foot

• Increase in pain with certain postures - often sitting with the legs stretched out or driving a car is terrible, but standing, walking or lying down eases pain

• Electrical and/or shock-like pain down the back of the leg

• In extreme cases, weakness of the muscles in the lower leg and hamstrings

Usually, the pain is just on one side as it’s only one nerve that’s affected, not both at the same time.

How Do We Treat It?

At the root of it, sciatica is a symptom, not a diagnosis. When the sciatic nerve is pressed on or irritated by other structures, sciatic pain is the result.

Before addressing the sciatica itself, we need to figure out what’s causing the pressure on the sciatic nerve in the first place. The likely candidates include:

1. Herniated Disc - the nerve roots that exit the spinal cord to form the sciatic nerve can be compressed by a herniated disc, leading to sciatic pain. This is the most common cause of sciatica.

2. Spinal Stenosis - literally meaning “narrowing”, stenosis occurs when the tunnel of bone that allows the nerve roots to escape shrink, often by bone spurs or a loss of disc height.

3. Arthritis - When arthritis hits the spine, it usually leads to bone spurs around the exiting nerve roots, similar to stenosis.

4. Pelvic and/or SI Joint Hypermobilities - most of the muscles that lie over and around the sciatic nerve are attached to some point of the pelvis. When the pelvis is moving more than it should, these muscles often tighten down to try and stabilize the pelvis. When this occurs, an unintended consequence is pressure on the sciatic nerve. Pregnant women with sciatica: this is likely you!

5. Piriformis tightness - this deep muscle lies right over the sciatic nerve. If it’s too tight, it can squeeze the sciatic nerve.

The treatment approach is defined by the source of the sciatic nerve irritation. Is the problem at the spine? Is it a muscle imbalance or spasm causing the problem?

We see a lot of “one size fits all” fixes for sciatica online. These often don’t work because the root problem isn’t identified and addressed. If your sciatic pain isn’t going away, your best bet is to be assessed by your medical practitioner and figure out what’s driving your sciatica.

My Sciatica Is Gone! How Can I Prevent It From Coming Back?

There are loads of ways to keep sciatica at bay! The top tips:

• Stay active - Look at all those causes of sciatica listed above. All of them benefit from exercise - strengthening, stretching, MOVING. In fact, one of the biggest risk factors for sciatica is prolonged sitting. So if you don’t want sciatica, move more!

• Maintain a healthy weight - a normal weight keeps your spine healthier with less disc pressure and a lower chance of degenerative changes, both of which contribute to sciatic pain.

• Sit properly - I’m talking feet on the floor, bum at the back of your chair with a lumbar support properly. Not sure what that looks like? Check out our blog on proper ergonomics.

• Strengthen your core - A strong core means a supported spine and pelvis, preventing sciatic nerve compression.

• Use good body mechanics - Considering a disc injury is the leading cause of sciatica, protect those discs! Lift with your legs and try to not twist as you lift a heavy load. Hold those heavy loads close to your body and find a friend if it’s really heavy.

Ask A Physio: Any Tips for Mouse Finger Pain?

So I don’t know about you, but COVID has certainly pushed me to using my computer a lot more. A. Lot. More. My body is feeling it, too - my neck is stiffer than it was, my hands are tired and my shoulders make a lot of noise after a long session on the computer.

We know that prolonged postures of any kind - standing in one spot, sitting still - aren’t great for anyone. Our bodies are for movement and all too often we get stuck in postures for hours at a time. When that prolonged posture is on the computer, that finger and wrist pain is often directly related to the position of the neck and shoulder as much as it is the wrist and hand.

So what should you do? The best thing you can do is set an alarm for 30 minutes and make a point of moving and stretching your body. If you have two minutes (or less!), this movement and stretching routine can help combat the stiffness and soreness associated with prolonged computer use.

Without further ado, presenting:

Top Ten Exercises for Computer-Related Pain

1. Shake it out! - I love a good shake - who doesn’t? Sit up straight, take your wrists and hands and give them a good shake, letting your fingers fly.

2. Chin to chest - Something we often forget is how much posture contributes to pain further down the chain. Sit up straight and tuck your chin into your chest, feeling a stretch down the back of your neck. Hold this for 10ish seconds.

3. Ear to shoulder, then a twist - Still sitting up straight, lean your ear to your shoulder and hold it for about 10 seconds. Then twist your head so your nose gets closer to your armpit; hold this for another 10 seconds. Repeat on the other side.

4. Shoulder rolls - Still sitting up straight (are you sensing a theme yet??), roll your shoulders up to your ears then squeezing them back and down, pushing your shoulder blades as far down your back as you can. Bring your shoulders forward then back up to your ears. Do this 5 times.

5. Wrist stretch - Stretch your right arm in front of you and bend your wrist and fingers back. Use your left hand to pull your right fingers further back, feeling a stretch in your forearm. Hold for 10ish seconds and repeat on the other side.

6. Prayer stretch - Place your hands together in a prayer position in front of your chin. Lower your hands down, keeping your palms together and feeling a stretch in your forearms. Hold for 10ish seconds.

7. Finger stretch - Place all your finger tips together - think Mr. Burns from the Simpsons - and push your fingers together. Keep your fingers together and pull your palms away from each other. Stretch your thumbs away from your other fingers. Feel a stretch for 10ish seconds.

8. Wrist circles - Draw circles with your wrists! 5 in one direction, 5 in the other.

9. Hand fist and open - Squeeze your hands into tight fists for a few seconds. Then stretch your hands out wide, reaching your fingers out as far as you can for a few seconds. Repeat 5 times.

10. Finish this off with a final shake!

The better you support your body with proper ergonomics (see our previous two ergonomic blogs here and here) and frequent movement breaks, the less likely you’ll suffer from computer related pain. So set that alarm, stretch it out and stay pain free!
