A new 10-year study found that a common knee surgery for worn cartilage left patients with more pain, faster arthritis, and higher odds of a second surgery than patients who got no surgery at all. If a surgeon has told you that you need arthroscopic surgery for a meniscus tear, get a physical therapy evaluation first — in Washington, you don’t need a referral to do it.
What did the new study actually find?
Researchers in Finland tracked patients for 10 years after arthroscopic surgery for degenerative meniscus tears — cartilage worn down by age, not torn in an accident. Half the group got the real surgery. Half got a skin incision and nothing else. A decade later, the surgery group had more pain, arthritis that progressed faster, and a higher rate of ending up in a second surgery, usually a total knee replacement.
One of the study’s authors put it bluntly: he said he didn’t know how he’d defend the procedure at all. That’s a researcher looking at his own data and concluding the surgery failed its own test.
This isn’t a one-off result, either. The same research group ran a smaller version of this trial back in 2013 and found the surgery didn’t outperform sham surgery at two years. This new data just extends that finding out to a full decade.
Does this apply to your knee?
Not automatically. This matters, because a scary headline shouldn’t talk anyone out of a surgery they actually need.
The study covers degenerative meniscus tears — the kind that show up on an MRI in a knee that’s simply aged, in a patient who wasn’t hurt in a specific incident. It has nothing to do with an ACL tear from a fall on the trail, or a clean meniscus tear from a bad landing during a rec-league game. Those are different injuries, and surgery is often the right call for them.
Here’s the detail that trips people up: tears like the ones in this study are common in people over 50, and a lot of those knees don’t hurt at all. The tear showing up on the scan and the pain you’re feeling are frequently two separate stories. Removing the tear doesn’t fix the pain if the tear was never what caused it.
What should you do before agreeing to knee surgery?
If your MRI shows a degenerative meniscus tear and nobody has put you through a real course of physical therapy first, you don’t have enough information yet to decide on surgery.
In Washington, you have a shortcut most patients don’t use: direct access. You can see a physical therapist without a doctor’s referral. That means before you ever schedule an OR date, you can get an independent evaluation — from someone who isn’t the surgeon recommending the operation — on whether your knee actually needs one.
We see this pattern regularly at our Bremerton clinic: a patient gets an MRI for knee pain, the report flags a meniscus tear, and surgery gets presented as the next step, sometimes in the same appointment. What often doesn’t get said is that the same tear pattern shows up on plenty of pain-free knees, and a structured strengthening program resolves the pain for a large share of these patients without a surgeon ever picking up a scalpel.
We treat a lot of knees that spend their days on ferries, boats, and steep Kitsap trails — people who need a joint that holds up under real use, not just one that looks clean on paper. That’s the standard we hold PT to before anyone talks about surgery.
What does “real PT first” actually mean?
Not a handout of stretches. A real trial means:
- A one-on-one evaluation that identifies what’s actually driving your pain — not just what the MRI report says
- A specific strengthening and movement plan built around the muscles that stabilize your knee
- Regular reassessment over several weeks, so progress is tracked, not guessed at
- A straight conversation about surgery if PT genuinely isn’t working
If you’ve done that and you’re still stuck, surgery may be the right next step. This isn’t an anti-surgery argument. It’s an argument against skipping the step that tells you whether you need it.
Frequently Asked Questions:
Do I need a doctor’s referral to see a PT for knee pain in Washington?
No. Washington allows direct access, meaning you can schedule with a physical therapist first, without seeing a doctor or getting a referral.
Does this study mean I shouldn’t get knee surgery?
No. It applies specifically to degenerative meniscus tears in older adults, not tears from an acute injury. Talk through your specific MRI and history before drawing conclusions.
What if a surgeon already recommended this surgery for me?
Call a physical therapist before you book it. Ask two things: is the tear from a specific injury or is it degenerative wear and tear, and has anyone tried a real strengthening program on the knee first.
