What Osteoarthritis Actually Is
Osteoarthritis (OA) is a degenerative joint disease characterized by the progressive breakdown of articular cartilage — the smooth, protective tissue that cushions the surfaces of bones where they meet in a joint. As cartilage wears down, bones begin to contact each other more directly, producing pain, stiffness, swelling, and eventually significant loss of function. The process also involves changes to the underlying bone, joint lining, and surrounding soft tissue structures. It is a whole-joint disease, not simply a cartilage problem.
The knee is the most commonly affected joint, though osteoarthritis also frequently affects the hip, shoulder, and small joints of the hand. Risk factors include age, prior joint injury, excess body weight, repetitive mechanical loading from occupational or athletic activity, and genetic predisposition. OA is not exclusively a disease of older adults — it affects younger people as well, particularly those with a history of joint injury.
What makes OA clinically difficult is that its progression is largely irreversible with currently available treatments. Cartilage has poor regenerative capacity. Once lost to the degree visible on imaging, it does not grow back through medication or exercise alone. Standard care manages symptoms. It does not restore what has been damaged.
Where Standard Treatment Falls Short
The first-line approach to osteoarthritis involves a predictable sequence: activity modification, weight management, physical therapy, over-the-counter anti-inflammatory medications, and if those fail, prescription NSAIDs or corticosteroid injections. Each of these has genuine value within its appropriate scope — and each has limits.
NSAIDs reduce inflammation and pain effectively in the short term, but the systematic review literature raises concerns about their long-term safety profile, particularly gastrointestinal complications with extended use. Corticosteroid injections can provide meaningful short-term pain relief, but repeated injections have been associated with accelerated cartilage breakdown over time — meaning the intervention used to manage the disease may, with repeated use, contribute to its progression.
Hyaluronic acid injections — another common option — have shown variable results in clinical trials, with some populations responding more favorably than others. Physical therapy improves function and can slow disease progression, but it cannot reverse existing structural damage.
At the far end of the treatment sequence sits total joint replacement, which is highly effective for late-stage OA and well-justified when the disease has progressed to that point. But many patients live with moderate to significant OA for years before reaching surgical candidacy — or never want surgery at all. That space between conservative management and joint replacement is where regenerative approaches become worth a serious look.
The Case for Addressing the Joint Environment
The regenerative medicine approach to osteoarthritis starts from a different premise than symptom management. Rather than focusing solely on pain reduction, it asks what is happening in the joint environment at a cellular and biochemical level — and whether introducing biological materials might support repair processes the joint can no longer mount independently.
PRP (platelet-rich plasma) delivers concentrated growth factors derived from the patient’s own blood. The systematic review referenced above notes that PRP may provide additional symptomatic benefit without the risk of harm associated with long-term NSAID use or repeated corticosteroid injection — a meaningful distinction for patients managing a disease that spans decades.
Neither treatment cures osteoarthritis. What they offer is physician-supervised, autologous care that may be evaluated as part of an individualized treatment plan. Results vary by individual, and candidacy depends on the degree of degeneration and the patient’s overall clinical picture.
Having the Honest Conversation About What to Expect
Patients who come to us after years of managing osteoarthritis have usually already been through the standard sequence. They know what cortisone does and doesn’t do. They’ve been told surgery is the eventual endpoint. What they’re looking for is whether there’s something meaningful in between — and whether anyone will discuss it honestly.
We do. Our consultations start with your imaging and your history, not a protocol we apply to everyone. We explain what the research shows, where the evidence is strong, and where it’s more limited. We discuss realistic timelines — regenerative treatments don’t produce the immediate relief that corticosteroids can, and the tissue-level changes they promote develop over weeks to months. We address cost directly, because these treatments are typically not covered by insurance, and we think that should be part of the conversation from the start rather than a surprise.
Two questions come up consistently: whether anything can actually slow OA progression, and whether these treatments are worth pursuing if surgery is eventually inevitable. Some research has examined whether autologous procedures may have effects beyond immediate symptom management — we discuss what that evidence shows, and where its limits are, during consultation, but that evidence is still developing, and we present it as such. On surgery: even if joint replacement is eventually warranted, maintaining better joint function and lower pain levels in the years before that point has real value.
Frequently Asked Questions
Can regenerative treatments replace my current medications? That depends on your individual situation and should be discussed with your provider. Some patients find their need for anti-inflammatory medications decreases following regenerative treatment; others continue their current regimen alongside it. We don’t make blanket recommendations about medication changes — those decisions belong to you and your prescribing provider.
How do I know if my OA is too advanced for regenerative treatment? Degree of degeneration on imaging is one of the primary factors we evaluate during consultation. Bone-on-bone joint changes — where cartilage loss is essentially complete — typically fall outside the range where regenerative treatments are expected to provide meaningful benefit. We review imaging during every evaluation and give a direct assessment of what we find.
I’ve already had cortisone injections. Does that affect my candidacy? Prior corticosteroid injections don’t automatically exclude you from regenerative treatment candidacy, but the timing and frequency matter. We review your injection history as part of the consultation.
How long does it take to notice results from PRP for OA? Most patients notice changes over a period of weeks to months. Cellular and tissue-level processes don’t follow a fixed schedule, and individual responses vary. We follow up with patients after treatment to track how they’re progressing.
Is this covered by insurance? Regenerative treatments for osteoarthritis — including PRP — are not typically covered by standard insurance plans. We discuss costs during the consultation before any commitment is made.
Key Takeaways
- Osteoarthritis has no cure and typically persists for decades. Standard treatments — NSAIDs, corticosteroids, hyaluronic acid injections — manage symptoms but carry long-term risk profiles and do not restore damaged cartilage.
- The gap between conservative care and surgical intervention is where regenerative approaches — PRP, offer a biologically different option for managing the joint environment.
- Published review evidence notes that PRP may provide symptomatic benefit without the long-term risks associated with NSAIDs or repeated corticosteroid use.
- Neither regenerative treatment cures OA. Results vary by individual. Candidacy depends on degree of degeneration, overall health, and prior treatment history.
- These treatments are typically not covered by insurance. Cost is discussed during the consultation before any decision is made.
If osteoarthritis has been limiting your life and the standard options have reached their ceiling, the next step is a conversation about what the evidence actually supports for your specific presentation.
