Knee pain can change your life — from forcing you to take the elevator instead of the stairs to bracing yourself before standing up from a chair.
So when your knee aches, catches or feels like it might give out, it’s easy to assume something inside must be “torn” and needs to be surgically cleaned up.
That’s especially true when an MRI shows a meniscus tear.
For decades, people with knee pain have undergone a procedure to trim the damaged part of the meniscus — the rubbery shock absorber inside the knee — hoping to relieve pain and restore function.
But a major 10-year study is challenging that assumption…
And it’s warning that, for many people with age-related meniscus tears, surgery may not help — and could make things worse.
Surgery offered no real benefit after 10 years
The study, by researchers at the University of Helsinki, followed adults with degenerative meniscal tears — the wear-and-tear type common in middle age and older adulthood.
Participants were randomly assigned to either real arthroscopic partial meniscectomy or sham surgery. In other words, some underwent the actual trimming procedure, while others went through a placebo procedure without the meniscus trimming.
After 10 years, the people who had real surgery did not have better symptoms or knee function than those who had sham surgery.
In fact, they tended to do worse, including:
- More knee symptoms
- Poorer function
- Greater progression of osteoarthritis
- A higher chance of needing additional knee surgery, including knee replacement or high tibial osteotomy
The researchers called it a case of medical reversal — when a broadly used treatment proves ineffective, or even harmful, because the original assumption behind it was wrong.
In this case, the assumption is that a torn meniscus is the main cause of knee pain.
As principal investigator, Raine Sihvonen explains, that assumption “does not withstand critical examination.” Based on current understanding, pain in joints such as the knee is often related to degeneration brought on by aging.
In other words, for middle-aged and older adults, a meniscus tear may be more like gray hair inside the knee — a sign of aging and wear — not always the true cause of pain.
That doesn’t mean every meniscus tear should be ignored. This study focused on degenerative meniscal tears, not sudden traumatic injuries or cases where the knee truly locks. Those situations still deserve medical evaluation.
But it does mean that an MRI finding alone should not automatically send you to the operating room.

What to try before meniscus surgery
A tear on imaging doesn’t automatically mean the tear is causing your pain.
That’s why it’s important to look at the whole kinetic chain: foot mechanics, ankle mobility, hip strength, glute activation, pelvic alignment, gait pattern and how the knee tracks when you squat, walk or climb stairs.
A physical therapist, sports medicine clinician or other qualified conservative-care provider can assess these movement patterns and help identify what may be feeding stress into the knee. Some chiropractors with musculoskeletal rehab training may also offer mobilization, soft tissue work and corrective exercises.
Support the knee while you rebuild strength
For people whose knee pain is tied to osteoarthritis or age-related joint degeneration, recent research suggests knee braces may be one of the most useful non-drug options.
One large analysis of nearly 10,000 patients found that knee braces were ranked highest overall by the people who used them.
The right brace depends on the problem…
The Arthritis Foundation notes that an unloader brace may help people with arthritis affecting the inner, or medial, part of the knee. If weakness under the kneecap is contributing to pain, a neoprene brace with a cutout for the kneecap may offer support.
Sleeve-style braces can be useful for mild swelling and aching. Hinged braces may be better if the knee feels unstable, buckles slightly or needs more side-to-side control.
A brace is not a cure, but it may help support the joint while you work with a professional on the strength, mobility and movement patterns that protect your knees long term.
Keep moving, but choose the right kind of movement
The same review also found that hydrotherapy and exercise can help aging knees by relieving pain and improving mobility.
Another major study found that aerobic exercise — especially walking, cycling and swimming — was one of the most effective and safest exercise options for knee osteoarthritis. It improved pain, function, walking ability and quality of life.
That’s important because painful knees often push people into a trap: You move less because it hurts, but moving less weakens the muscles that support the knee, which can make the joint feel worse.
The answer is not to push through sharp pain. It’s to find movement the knee can tolerate and build from there.

Could regenerative therapies help?
Regenerative therapies like platelet-rich plasma, bone marrow aspirate concentrate and prolotherapy may also come up in conversations about knee pain.
But like surgery, they are not a guaranteed solution.
Platelet-rich plasma, or PRP, uses a concentrated portion of your own blood platelets, which contain growth factors involved in healing and inflammation control.
Bone marrow aspirate concentrate, or BMC/BMAC, uses concentrated cells and signaling factors from your own bone marrow.
Prolotherapy involves injecting a dextrose-based solution into irritated or weakened connective tissue to stimulate a healing response.
These treatments are not usually covered by insurance and may not be approved by the FDA. So before paying out of pocket for PRP, BMAC or prolotherapy, ask:
What diagnosis is being treated? How many injections are expected? What evidence supports it for my specific knee problem? What are the risks? And what happens if it doesn’t work?
Can supplements help?
Some nutrients may help support the tissues and systems your knees rely on — including cartilage, connective tissue, inflammation balance and bone strength.
- Glucosamine and chondroitin are two of the best-known joint supplements because they are natural components of cartilage. Avoid, however, if taking blood thinners.
- Collagen may provide building block support for connective tissue.
- Omega-3 fatty acids are often used because they help regulate inflammation. The Arthritis Foundation notes that omega-3s may also help reduce pain.
- Vitamin D is essential for managing pain, reducing inflammation and supporting surrounding knee tissues from further degenerative changes like osteoarthritis.
The bottom line for your knee
When it comes to caring for your knee, the foundation still matters most: strength, mobility, weight management if needed, anti-inflammatory foods, better footwear, the right brace if appropriate and a plan that keeps you moving without overloading the joint.
The results of this 10-year study make one thing clear: For many people with degenerative meniscal tears, the best knee strategy may not start in the operating room.
It may start with asking better questions — and giving your body the support it needs to heal naturally.

FAQ: Meniscus Surgery and Knee Support
No. Many meniscus tears in middle-aged and older adults are degenerative, meaning they’re related to age-related wear rather than a sudden injury. In those cases, surgery may not improve pain or function more than conservative care, and a 10-year study found partial meniscectomy offered no real long-term benefit over sham surgery.
Some meniscus tears may improve with time, movement modification, physical therapy and better joint support. However, healing depends on the type, location and severity of the tear. Tears that cause true locking, major instability or follow a sudden injury should be evaluated by a healthcare professional.
For degenerative knee pain, conservative options may include physical therapy, strengthening exercises, better footwear, weight management if needed, knee bracing, walking, cycling, swimming or hydrotherapy. The goal is to reduce stress on the knee while improving the muscles and movement patterns that support the joint.
A knee brace won’t repair a torn meniscus, but it may help support the joint, reduce strain and improve confidence during movement. Braces may be especially useful when knee pain is related to osteoarthritis, mild instability, swelling or age-related joint degeneration.
Glucosamine, chondroitin and collagen are often used to support cartilage and connective tissue. Omega-3s may help support a healthy inflammatory response, while vitamin D supports bone and muscle health. Supplements won’t repair a torn meniscus, and some can interact with medications, so ask your healthcare provider what’s appropriate for you.
Get medical evaluation if knee pain follows a sudden injury, causes major swelling, prevents you from bearing weight, leads to true locking, or makes the knee feel unstable or unsafe. These symptoms may need a different approach than typical degenerative knee pain.
