Knee Osteoarthritis
Knee Arthritis? Why "Bone on Bone" Isn't the End of the Road
Few phrases stop people in their tracks like "bone on bone." Maybe you heard it after an X-ray,
or maybe your knee just started complaining on the stairs, getting out of the boat, or halfway
through a round at the golf course. Either way, if you've been told you have knee osteoarthritis,
you've probably wondered whether your active days are numbered.
Here's the short answer: they're not. Let's talk about what knee arthritis actually is, what it isn't,
and what physical therapy can do about it.
What "arthritis" on an X-ray really means
Osteoarthritis is often described as "wear and tear," which makes it sound like your knee is a
tire tread wearing down to nothing. That picture is outdated — and it does real damage,
because it convinces people to stop moving the very joint that needs movement most.
Here's what surprises almost everyone: studies of adults with no knee pain at all routinely show
arthritis on X-rays and MRIs. Cartilage thinning, bone spurs, meniscus changes — they show up
in pain-free knees all the time, especially as we get older. Like the disc findings we talked about
in our back pain post, these changes are often as normal as gray hair.
And the flip side is just as true: the amount of arthritis on your X-ray does a poor job of
predicting how much pain you feel. Some people with "severe" imaging findings hike, golf, and
chase grandkids pain-free. Others with mild findings hurt a lot. If the picture doesn't determine
the pain, then the picture doesn't determine your future either.
That's why we keep coming back to the same message: hurt does not equal harm.
So why does my knee hurt?
Pain is your body's alarm system, and its job is protection. When a knee has been sore for a
while — or when you've been told it's "bone on bone" and started bracing for the worst — that
alarm system can get more sensitive. Add in a stretch of poor sleep, extra stress, or months of
avoiding activity, and the alarm gets louder even though the house isn't on fire.
Meanwhile, the knee itself gets caught in a frustrating loop: it hurts, so you move less. You
move less, so the muscles around it weaken and the joint gets less of the nourishing motion
cartilage loves. Weaker and stiffer, the knee complains more. The alarm gets louder still.
The good news? That loop runs in both directions — and physical therapy is how you reverse it.
Movement is medicine for arthritic knees
This isn't just our opinion. Exercise therapy is the most strongly recommended first-line
treatment for knee osteoarthritis in every major clinical guideline — ahead of injections, ahead
of medications, and long before surgery enters the conversation.
Cartilage doesn't have a blood supply the way muscle does. It gets its nutrition from movement
— loading and unloading, like a sponge being squeezed and released. Motion is lotion, quite
literally. And strong muscles around the knee act like shock absorbers, taking load off the joint
with every step.
At Alex PT, patients regularly tell us the turning point wasn't a gadget or a quick fix — it was
finally understanding that their knee was adaptable, not fragile, and having a plan that met them
where they were.
What your plan might look like
Everything starts with a full one-on-one evaluation — no assembly line, no hand-off to a tech
(though Stella or Margot may insist on saying hello). We listen to your story, watch how you
move, and figure out what your knee can tolerate today. From there, most plans include some
combination of:
Progressive strengthening. The single most effective treatment we have. We start
where your knee is right now — even if that's gentle — and build gradually, so the joint
adapts instead of flaring.
Hands-on manual therapy. Skilled techniques to ease stiffness and calm pain so
exercise feels doable, not daunting.
Dry needling. A targeted way to release guarded, tense muscle around the knee and
hip — many patients notice a difference quickly.
Education. Understanding your pain takes away its power. You'll leave knowing what's
going on in plain language — no scary phrases, no "bone on bone" doom.
The goal isn't endless appointments. It's handing you the tools so you don't need us.
"But don't I just need a knee replacement?"
Maybe someday — replacements are a great option when a knee truly needs one. But research
shows that many people who complete a solid course of exercise-based physical therapy delay
surgery for years or end up not needing it at all. And if you do eventually have a replacement,
going in stronger means coming out of recovery faster. Either way, physical therapy first is the
smart play.
In most cases you don't need a referral to start — Minnesota allows direct access to physical
therapy, so you can typically book an evaluation without seeing a physician first. And Alex PT
now accepts insurance plans, making care easier to access than ever.
