Osteoarthritis is the most common form of arthritis, and it is often dismissed with a shrug: it is wear-and-tear, nothing to do about it, come back when you need a joint replacement. That framing is out of date. Osteoarthritis is a disease of the whole joint, involving cartilage, bone, ligaments, and the surrounding muscles, and there is a substantial amount that can be done to reduce pain, preserve function, and delay or avoid surgery.
Surgery, when it is needed and done well, is remarkable. But for many people, the years between the first ache and the operating room are longer than expected, and how those years are spent matters.
What is happening in the joint
Cartilage thins and roughens. Underlying bone remodels, sometimes forming osteophytes. The joint capsule can become inflamed. Muscles around the joint often weaken, partly from disuse and partly from pain-related inhibition. All of these can contribute to the symptoms, and importantly, the amount of change visible on an X-ray correlates only loosely with how much pain a person experiences. Two people with similar imaging can have very different functional lives.
The most commonly affected joints are the knees, hips, hands, and spine. Symptoms usually build gradually: stiffness after inactivity, pain with use that eases with rest early on and becomes more constant later, and, for some, occasional flares of swelling.
What actually helps
The American College of Rheumatology and other groups have converged on a set of core recommendations that are stronger than the reputation of arthritis care would suggest.
- Exercise is the single most effective non-surgical treatment for knee and hip osteoarthritis. This includes aerobic activity, strength training, and, for some, neuromuscular training. Water-based exercise is a reasonable option for people with significant pain.
- Weight management matters, particularly for the knees, where each pound of body weight translates to several pounds of force across the joint with each step.
- Physical therapy with a therapist who understands osteoarthritis can make the difference between exercises that help and exercises that flare things.
- Topical NSAIDs, applied directly to the joint, work well for hand and knee osteoarthritis with a much lower systemic side effect profile than oral versions.
- Oral NSAIDs, used judiciously and with attention to kidney, cardiovascular, and gastrointestinal risks, are effective for many.
- Duloxetine, an antidepressant with pain-modulating effects, has evidence in osteoarthritis and is worth considering when standard analgesics fall short.
- Intra-articular corticosteroid injections can provide meaningful, if temporary, relief during flares. They are not something to reach for casually or repeatedly.
What has weak or mixed evidence
Several popular treatments have less support than their marketing suggests. Glucosamine and chondroitin have inconsistent evidence and, at best, modest effects. Hyaluronic acid injections have fallen out of favor in many guidelines. Platelet-rich plasma and stem cell injections are marketed heavily and studied lightly; the evidence for durable benefit remains thin. Arthroscopic surgery for degenerative knee arthritis, once common, is no longer recommended for most patients.
This does not mean nothing works. It means the interventions with real evidence are, unfortunately, the ones that require effort rather than a procedure.
The joint that hurts is often not the joint that needs the most attention. Strengthening the muscles around it usually matters more than anything done to the joint itself.
Living with a bad day
Osteoarthritis pain varies. Weather, sleep, stress, and activity all play a role. Pacing, alternating heat and ice, and giving a flare a few days without pushing through are reasonable. So is not treating every flare as a sign of catastrophic progression. Most flares settle.
Assistive devices, whether a cane on the opposite side of a bad hip, better shoes, or a properly fitted knee brace, are worth trying without embarrassment. They can extend function significantly.
When surgery makes sense
Joint replacement is considered when pain and functional loss are significant, imaging supports the diagnosis, and non-surgical options have been tried adequately. The results, particularly for hip and knee replacement, are among the best in medicine. But timing is a shared decision, not a threshold to cross the moment imaging looks bad.
The bottom line
Osteoarthritis is manageable, and the tools that work are largely the unglamorous ones: movement, strength, weight, targeted medications, and thoughtful use of injections. Treated well, the years before surgery can be long and full.
