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!

Exercise and Arthritis - The GLA:D Way

Arthritis can be a life-changing disease. I have arthritis myself - I feel your pain!

As physiotherapists, we treat a lot of arthritis and hear a lot of misconceptions - “I shouldn’t squat down, that’s bad for my knees” or “I’m supposed to rest when my hip hurts”. But what if we told you this way of thinking is wrong? What if we told you that you could gain some control over your pain simply by changing the way you move?

The research has come a long way. Want the up-to-date info? Keep reading!

Top Ten Facts About Osteoarthritis (aka OA)

1. It is not “something that just happens” as we age! It is a disease that develops slowly over years and years, often not being diagnosed until quite late in the process.

2. Over 20% of people in Canada have arthritis, most of that being OA. I don’t know about you, but that number blows my mind.

3. OA affects young people as well. I was diagnosed with arthritis in my mid-thirties after years of chronic ankle sprains (prior joint injury - a big risk factor!) and I’m not alone. 60% of people with OA are younger than 65 when they are diagnosed and that’s usually after several years of going undiagnosed. We exist!

4. Meniscal tears and muscle weakness are early signs of OA. Research has also shown the faster we treat these with appropriate exercises, the more you can delay the onset of OA symptoms.

5. You do not need an X-ray for an OA diagnosis. In fact, X-rays are only 30-40% accurate in detecting OA. X-rays usually only pick up OA in the later stages. In other words…

6. Ignore the X-ray. Did your X-ray come back negative? Or maybe it shows “bone-on-bone”? Great news - it doesn’t matter! X-ray findings do not predict or define your symptoms or how you function. It doesn’t matter if you have the tiniest bit of OA or the worst case ever - what matters is how it feels, how strong you are and what you can do with it.

7. Physiotherapists can diagnose OA. We do this by listening to your symptoms, testing out your joint and taking a close look at your risk factors.

8. Losing 5% of your body weight can really help reduce your joint pain for those who are overweight. The force that goes your through your knees with each step is equivalent to four times your body weight. If you take 10 lbs off the scale, 40 lbs of stress are removed from your knees when walking.

9. Motion is lotion - your body is meant to move, even when OA is an uninvited guest. Physical activity helps lubricate the joint and maintains the health of the cartilage, even if there’s not much left.

10. Only 2% of people with hip and knee arthritis will go on to get a replacement. The decision to get a joint replacement is often a difficult one and based on many factors. That leaves a whole lot of people in need of management strategies.

The Best Thing We Can Do For OA?
EXERCISE

Research has shown again and again and again that exercise:

• has better long term pain control than drugs

• improves the health of cartilage

• helps delay (or even completely avoid!) surgery and all the possible complications that comes along with it

So what kind of exercises should you be doing? Well we are GLAD (Ha! Get it? No? You’ll get it in a second…) you asked!

Introducing The GLA:D (TM) Program

The Good Life with Osteoarthritis in Denmark (also known, thankfully, as GLA:D) (TM) program was developed by researchers in, you guessed it, Denmark!

GLA:D (TM) is a group exercise class for those suffering with hip and knee OA. This six week program’s goal is to teach participants about OA and give them the best we have at combating it: appropriate exercises done properly.

The research behind GLA:D (TM) has some incredible findings:

• 30% reduction in pain levels at both 3 and 12 months after the program

• More than 50% reduction in use of painkillers

• Half the anxiety around fear of movement and damaging joints with activity

• Less than a third of sick time from work

• Significant improvement in quality of life

GLA:D (TM) has four components:

1. Initial assessment - Before you even get started in the program, a physiotherapist will do a one hour 1:1 appointment with you to make sure you’re appropriate for the GLA:D program, test out your hip or knee and go over all the exercises with you.

2. Education sessions - Over 2 or 3 classes, participants learn about osteoarthritis and its risk factors, symptoms, coping strategies and self help tools. They will also learn about the science behind pain and how they can use this to help control their own pain.

3. Exercise sessions -12 sessions of physiotherapist-led group classes lasting an hour each. These sessions focus on neuromuscular exercise - strengthening muscles with a huge focus on control throughout the whole movement.

4. Outcome measures - At the beginning of the program and then again at 3 months and 12 months afterwards, participants will be contacted by researchers about their adherence to the exercise program, their pain levels and how they are functioning. This data is used for public health funding and future research.

Starting in January 2021, Ladner Village Physiotherapy will offer the GLA:D (TM) Program online!

Knee Arthritis 101: The Basics

Arthritis is a big topic and there is no way I could cover it all so today I am just going to cover some of the basics to help you understand what is going on with your body.

First of all, it’s important to note that there are many types of arthritis. The two most common types are:

1. Degenerative arthritis, also known as osteoarthritis (OA for short)

2. Inflammatory arthritis such as rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis

Today we will be discussing osteoarthritis of the knee.

Here are the top five things you absolutely need to know about arthritis:

1. Arthritis is not a catastrophic diagnosis. You can continue to thrive and lead an active lifestyle with an arthritic knee and it’s not the end of the world. 

2. Exercise is your best friend. Say this with me, three more times!

3. X-Ray findings are not proportionate to functionality or pain levels. Someone who describes “occasional stiffness” in their knee might have a “severe” x-ray, while a “mild” x-ray might belong to someone who describes unbearable pain that keeps them awake at night. X-rays do not give the whole picture!

4. Most knee pain from arthritis is from structures around the joint, and that pain can settle. It’s not the cartilage nor is it the outer compact bone causing the pain in your knee. 

5. There are things you can do to slow the progression and maximize your function.

Let me say this loud and clear:

Maintaining an active lifestyle is one of the best things you can do if you have arthritis!

Let’s look at a classic scenario.

Meet Stacy. She’s 62 and tweaks her knee while out for a run. That weekend she goes away for a vacation with her family. They play golf, tennis, and even go kayaking! Now her knee is quite sore and even swollen. Stacy decides to rest for a few weeks figuring she just over-did it while away. But it’s still swollen two weeks later.

She goes to her doctor, who orders an x-ray. The x-ray uses technical terms like “osteophytes” and “joint space narrowing”. She is told she has arthritis in her knee. That night Stacy has company for dinner and a friend, let’s call him Gary, said he has the same thing! Gary says his knee is “bone on bone” (and demonstrates grinding with his knuckles together while making an awful scraping noise) because all his cartilage has “worn away” and that his friend Steve had to have a knee replacement and limped for months.

Now Stacy is devastated. She doesn’t want arthritis and she certainly doesn’t want a knee replacement. She feels doomed. 

What happens next? 

Option A: Stacy is scared and wants to protect her knee. So Stacy stops playing tennis and stops golfing, she hires someone to do her gardening and doesn’t even really walk the dog anymore because if running hurts than walking probably isn’t great either right? (I want you to know it hurts me deep down inside to type that). But when Stacy suddenly stops exercise and spends many hours per day sitting her knee gets stiffer and her muscles get weaker.

In her mind this has confirmed her worst fears that her knee is in awful shape (look how quickly it’s deteriorating!) and tries to protect it further by resting even more. This cycle of inactivity can is bad news bears. 

It also doesn’t have to be this way. 

Option B: Stacy doesn’t worry about Gary or his friend Steve because she knows nothing about their situations and her doctor didn’t mention surgery at all. Stacy’s knee is still a bit stiff and sore so she modifies her activities for a few weeks. Runs on the dyke become walks with the dog and she tries pickleball with a few friends instead of tennis. To her delight the knee pain improves! Her muscles have stayed strong from her modified activities and she still enjoyed her time out and about. Now Stacy is in a position to gradually rebuild and reintroduce activities she enjoys as she is able. (This scenario is a lot better if you ask me). 

I will say it again: exercise is your best friend.

You are not wearing out the joint further by exercising. It is the most effective treatment for early and moderate knee OA (not to mention other health benefits). Exercise helps you maintain range of motion and strength. It is a lot easier to maintain strength and range than build it back up again after it has been lost.

Also, do not underestimate the benefits of exercise for the rest of your body. Many people who get an arthritis diagnosis self-impose activity restrictions and become more sedentary. This can have detrimental health benefits including increased risk of high cholesterol, heart disease and diabetes. Further, muscle weakness and joint stiffness can be contributing risk factors to falls. People with osteoarthritis experience 30% more falls than those without.

There is no use going too hard all day every day and being in extreme pain just for the sake of it but don’t stop all activity completely. You have to find a middle ground between activities that are challenging vs. aggravating (which is easier said than done). A physiotherapist can give you recommendations on which activities can be modified and help you figure out strength and range of motion exercises that are appropriate for you specifically. 

Ok, so I hope you get it by now. If you have arthritis you should exercise. But let’s keep going, shall we? Let’s discuss why this diagnosis doesn’t have to be all doom and gloom.

What causes the pain in knee arthritis?

The cartilage that degenerates has no nerve endings nor does the hard compact bone beneath it. So they cannot be the source of the pain. So which structure is actually responsible? 

The three main causes of knee pain associated with arthritis are:

1. Periosteum - the thin lining of tissue around the bone, it has nerve endings and supplies blood to the bone. If it tears it will hurt. 

2. Synovitis - Synovium is the connective tissue lining of the joint itself. It can become inflamed and very painful. Synovitis can feel like joint tenderness or pain, swelling, and nodules (hard lumps). 

3. Bone edema - This is more common in women who have underlying osteopenia or osteoporosis since the bones are already weaker. When stress on the bone increases, as is the case with arthritis, the deeper central layer of the bone can become swollen, which feels like a deep and intense ache. 

Remember:

• Not everyone with OA has these issues.

• If you do experience pain from these structures it will likely settle down over a few weeks or months and your knee pain and function will return back to baseline. It’s not forever.

• Like I mentioned above, the severity of an x-ray does not correlate with pain or disability.

• Treatment should not be based off of the x-ray.

• Do not let a bad x-ray be the reason you stop your favourite activity.

• Do not let a bad x-ray make you afraid of feel doomed.

• Please please please do not get surgery just because the x-ray is bad especially if everything else is great! (Disclaimer: obviously I am a physiotherapist and not your surgeon, so I’m not the one making calls on surgery. But if a surgeon is pushing for you to get surgery and you feel completely fine I would be asking why they feel it is necessary. They might have an excellent reason - that’s cool, making calls in grey areas is what they do all day every day so their opinion should be considered - I just don’t want you getting surgery because a friend of a friend had their knee done so you figure you might as well join the club). 

The Arthritis Foundation provides a very general list of things you can do to slow down the arthritis progression and keep you are healthy and active as possible. These include:

• Maintain a Healthy Weight: Excess weight worsens OA. Combine healthy eating with regular exercise to maintain a healthy weight.

• Control Blood Sugar: Many people have diabetes and OA. Having high glucose levels can make cartilage stiffer and more likely to break down. Having diabetes causes inflammation, which also weakens cartilage.

• Maintain Range of Motion: Movement is medicine for joints. Make a habit of putting your joints through their full range of motion, but only up to the point where it doesn’t cause more pain. Gentle stretching, raising and lowering legs from a standing or seated position, daily walks and hobbies such as gardening can help.  Listen to your body and never push too hard.

• Protect Joints: Make sure to warm up and cool down when doing exercise. If you play sports, protects joints with the right gear. Use your largest, strongest joints for lifting, pushing, pulling and carrying. Watch your step to prevent falls. Balance rest and activity throughout the day.  

• Relax: Find ways to reduce or avoid stress through meditation, listening to music, connecting with friends and family, doing fun activities, and finding ways to relax and recharge.

• Choose a healthy lifestyle: Eating healthy food, not smoking, drinking in moderation and getting good sleep will help you to feel your best.

I really hope you feel slightly better about an arthritis diagnosis. This is something that can be managed.
