A few weeks ago we talked about muscles vs. bones and I said something that tends to make people stop mid-scroll:
Your bones did not wake up one morning and decide to move.
I said what I said.
Muscles tell bones what to do. Bones are passengers. Muscles are the active fibers doing the work.
Last week we talked about why I care so much that the knees, hips, shoulders, and feet are all facing the direction they were designed to face.
Remember last week when I said the bones should point forward? This is why I care so much.
This week we’re going after one of the biggest phrases I hear as a posture therapist:
“I have bone-on-bone arthritis.”
Before everyone grabs their pitchforks, I am not saying arthritis is fake.
The pain is real. The inflammation is real.
In fact, the word arthritis literally means inflammation of the joint. “Arthron” means joint. “-itis” means inflammation.
What I am asking is:
Is the pain coming from the condition of the joint… or from the position of the joint?
Because those are not always the same thing.
Let’s Use the Knee Again
The knee is one of my favorite examples because it explains this beautifully.
Your knee is made up of:
- Femur: your thigh bone
- Tibia: your shin bone
- Meniscus: the shock absorber sitting between them
- Cartilage: the smooth surface covering the bones so they can glide instead of grind
Notice I said glide.
That matters.
Bones are designed to glide smoothly through movement.
When position changes and muscles stop participating, joint loading changes and the knee may stop moving as efficiently as it was designed to.
But what happens when the muscles stop doing their jobs?
Welcome back to our old friends:
Sleepy muscles.
When muscles underwork and stop participating, the body gets clever.
Helper muscles jump in.
Then helper muscles do work they were never designed to do.
Then they fatigue.
Then the joint loses support.
Bones stop gliding the way they were designed.
Load shifts.
Pressure changes.
The joint experiences ongoing irritation.
Over time that irritation may contribute to inflammation and pain.
The progression often looks more like this:
Sleepy muscle → helper muscles take over → helpers fatigue → instability → altered joint mechanics → ongoing irritation → inflammation → pain
That progression is not random.
It is compensation.
The Femur Problem Nobody Talks About
Most people assume arthritis means:
“The cartilage is gone everywhere.”
Maybe.
Maybe not.
Let’s talk medial knee arthritis for a second.
One of the compensation patterns I see all the time is the femur getting stuck in an externally rotated position while the tibia does not fully follow.
Now the bones stop gliding the way they were designed.
Pressure shifts.
Load changes.
Instead of distributing force evenly through the knee, more stress often ends up on the inside portion of the joint.
That means portions of the cartilage and meniscus may take more abuse while other portions of the joint may still have healthier surfaces available.
Read that again.
Degeneration is not always perfectly uniform across the entire joint.
There may be healthier portions of cartilage that simply were not carrying the load anymore.
So what happens if we improve position?
What happens if the muscles start participating again?
What happens if the femur unlocks and shifts closer to where it belongs?
You may uncover healthier portions of cartilage that were not carrying the load before.
That is a very different conversation than:
“Everything is destroyed forever.”
Your MRI Is Real. But It Isn’t The Whole Story.
Your MRI matters.
Your X-ray matters.
Those images are real.
But:
An image tells us condition. It doesn’t always tell us function.
I have seen people with awful imaging who barely hurt.
And I have seen people with very little showing up on imaging who can barely move.
That second group?
That is often a posture therapy perfect storm.
Lots of pain.
“Nothing significant” on imaging.
Meanwhile the muscles are asleep, compensation patterns are everywhere, hips have shifted, feet are collapsing inward, glutes checked out three exits ago, and the knee is left trying to negotiate world peace by itself.
Pain location does not always equal problem location.
Knee pain might involve the hip.
Hip pain might involve the foot.
Neck pain may start lower.
Shoulder pain may be coming from the rib cage or thoracic position.
Everything talks to everything.
The body is annoyingly efficient like that.
Self-Test Time
Stand on one leg.
Ten seconds.
Now switch.
Ask yourself:
- Did both sides feel the same?
- Did one side wobble more?
- Did one foot collapse inward?
- Did the hip shift?
- Did one knee complain immediately while the other side acted completely normal?
- Which side felt stable?
- Which side negotiated with gravity like it was filing a complaint?
Your body is giving you information.
Listen.
Because “fine” and “functional” are not always the same thing.
Tampa Athletes… I’m Talking To You Too
This is not just a problem for people who think arthritis belongs to retirement.
I see these compensation patterns in:
Pickleball players.
Golfers.
Runners.
Gym people who still think stretching fixes everything.
Tennis players.
Weekend warriors.
Youth athletes.
And yes, younger athletes are landing in these patterns earlier and earlier.
Phones.
Gaming.
Tablets.
Years of sitting.
Bodies adapt.
Not always in helpful ways.
It is one of the reasons I care so much about our NextGEN athletes.
I would much rather help a young athlete stay mobile, functional, balanced, and competitive now than meet them ten years later after compensation patterns have already moved in and unpacked their luggage.
Final Thought
Your bones didn’t organize a rebellion overnight.
Muscles pulled them there, and then stopped supporting them altogether.
If you have been told:
“Bone on bone.”
“Just arthritis.”
“This is what happens when you get older.”
It may be worth asking another question:
What position is the joint actually sitting in?
Because if the joint lost position…
Maybe it is not only the condition that deserves attention.
Maybe it is the support system too.
If you are dealing with knee pain, arthritis symptoms, balance issues, compensation patterns, movement limitations, or chronic pain around Tampa, a Functional Posture Assessment may help uncover what the muscles are doing, what the bones are following, and whether the joint is actually moving the way it was designed.
Because maybe the joint isn’t failing.
Maybe the support system failed first.
