Millions with joint pain and osteoarthritis are missing the most powerful treatment
Stiff knees and aching hips may seem like an inevitable part of aging, but experts say we’re getting osteoarthritis all wrong. Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage.
Scientists Found a Way to Regrow Cartilage Without Using Stem Cells
Scientists reversed joint damage in mice by reprogramming aging cartilage cells.
Your favorite snacks could be quietly wrecking your knees, new research suggests
New research suggests ultraprocessed foods may increase fat in thigh muscles, potentially raising the risk of knee osteoarthritis regardless of weight.
FDA-approved epilepsy drug may help reverse osteoarthritis damage
Researchers at Yale have identified a promising new approach to osteoarthritis that could do more than simply ease pain. The epilepsy drug lacosamide appears to block a protein involved in both pain signaling and cartilage destruction, helping damaged joints shift back toward repair in preclinical studies.

A surprisingly simple way to relieve knee arthritis pain without pills or surgery
A surprisingly simple change in how you walk could help relieve knee arthritis pain and even slow joint damage. In a year-long clinical trial, researchers found that adjusting the angle of a person's foot while walking reduced osteoarthritis pain by an amount comparable to medication, without requiring drugs or surgery. Even more promising, MRI scans revealed that participants who adopted the personalized walking technique experienced slower deterioration in a marker of knee cartilage health.
Knee osteoarthritis isn’t inevitable — here’s what you can do
Knee osteoarthritis can seriously affect mobility and quality of life, but its progression isn’t completely out of your control. Exercise, stronger leg muscles, a healthier diet, and even modest weight loss can dramatically reduce stress on the knees and help keep pain in check.
Federal Agency Unveils Three Potential Osteoarthritis Treatments
With funding from ARPA-H, three teams of researchers have regrown bone and cartilage, even entire knees, in animal studies. Human trials are not far off.
Stanford scientists regrow lost cartilage and reverse arthritis in major breakthrough
A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
This ultrasound treatment may help stop arthritis before it starts
A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsville found that continuous low-intensity ultrasound encouraged key immune cells called macrophages to shift from an inflammatory state toward one that supports tissue repair.
These shoes are best for hip and knee arthritis, according to science
Until now, health experts have assumed stable and supportive shoes are the best for people with osteoarthritis. But a new study shows this isn’t always the case.
A daily fiber supplement reduced knee arthritis pain and improved strength
A prebiotic fiber supplement reduced knee osteoarthritis pain while also improving grip strength and pain sensitivity in a six-week trial. The results hint at a fascinating gut-muscle-pain connection and suggest that a simple daily supplement may be easier to maintain than digital physiotherapy.
Goodbye joint replacements? Stanford scientists found a way to regrow cartilage and stop arthritis
Scientists have found a surprising way to regrow damaged knee cartilage by blocking a protein that becomes more abundant with age. In old mice, the treatment restored naturally lost cartilage and also helped prevent osteoarthritis after ACL-like knee injuries, while human cartilage taken from knee replacement patients began producing new, functional joint cartilage after exposure to the same inhibitor.
Science Snapshots: October 11, 2026
Three key science updates: 2024’s extreme, possibly normalizing rainfall; hypertension-linked osteoarthritis worsened by vasopressin; and an AI-proof checker solving Erdős problems autonomously.
This emerging treatment is helping people avoid knee replacement surgery
A minimally invasive treatment called GAE is helping people with chronic knee pain get back to gardening, cycling, and other activities without undergoing knee replacement surgery. Early studies suggest the procedure can provide years of relief by reducing inflammation inside the joint.
New Research Brings Joint Repair Closer for Millions With Osteoarthritis
DURHAM, N.C. — Osteoarthritis affects more than 32 million Americans, making it one of the leading causes of chronic pain, disability, and loss of mobility in the United States.For many people, treatment options are limited to managing pain with medications or repeated injections, and in severe cases, replacing the joint entirely through surgery.
Social Determinants of Health and Access to Orthopedic Care Among Seniors in Little Havana
Introduction: Little Havana, Miami, Florida, is a predominantly Hispanic neighborhood with many adults and seniors aged 65 and older at risk for osteoarthritis, osteoporosis, and associated frac...
Scientists Discover Ultrasound May Stop Arthritis Before It Starts
A new study suggests low-intensity ultrasound can influence immune cell behavior in ways that may reduce chronic inflammation and encourage tissue repair after joint injury.
Breakthrough to Restore Aging Joints Could Help Treat Osteoarthritis
'We are very excited'
Patient-centric health care ‘bundles’ can improve outcomes and cut costs
MyHealth Bundles have cut waiting times, improved maternity care and nonsurgical management of osteoarthritis, and saved patients and employers millions of dollars.
This emerging treatment could help people avoid knee replacement surgery
A minimally invasive procedure called genicular artery embolization could offer a new middle ground between conservative treatments and knee replacement for osteoarthritis. By blocking tiny blood vessels associated with inflammation, GAE can significantly reduce pain, with some patients reporting little or no pain afterward. Studies suggest the benefits may last two to four years in people who respond well.
Scientists reveal the best exercise for knee arthritis pain relief
A major review of 217 trials shows that aerobic exercise is the most effective option for managing knee osteoarthritis. Activities like walking, cycling, and swimming outperformed other exercise types in reducing pain and improving movement. While alternatives like strength training and mind-body exercises help, they are best used alongside aerobic workouts. The findings also confirm that exercise is a safe and essential part of treatment.

One injection could keep osteoarthritis drugs working for weeks
Scientists have created an injectable gel that can remain inside arthritic joints for weeks, slowly releasing medication while also improving lubrication. The approach could make it easier to deliver disease-modifying drugs directly where they are needed while limiting exposure elsewhere in the body.
