Knee Pain Treatment Without Surgery in Portsmouth, NH

A knee that aches on the stairs, swells after a walk, or stiffens every time you stand up can quietly shrink your whole life. For a lot of people, the next thing they hear is that a knee replacement is coming.
Here is what often gets left out of that conversation. Many patients with knee arthritis never needed the operating room in the first place. If you are looking for knee pain treatment without surgery in Portsmouth, NH, there are real options worth trying first.
At American Pain Institute, Dr. Greenspan helps patients across the New Hampshire Seacoast calm knee pain at the source. This is what those treatments are, who they help, and how to get started.
What Is Actually Causing Your Knee Pain?
Most chronic knee pain comes down to osteoarthritis, the slow wearing away of the cartilage that cushions the joint. As that cushion thins, the bones move with less protection, and the joint gets inflamed, stiff, and sore.
You may have heard the phrase “bone on bone.” It sounds final. It is not.
An X-ray showing advanced arthritis does not always match how a knee actually feels or how well it can respond to treatment. Plenty of people with rough-looking imaging get years of relief without ever being wheeled into surgery. The real question is not what your X-ray looks like. It is how much your knee limits your day, and what is driving the pain right now.
Non-Surgical Knee Treatments We Offer in Portsmouth
Dr. Greenspan focuses on targeted, minimally invasive care that treats the knee directly. Here are the options that help most patients.
Joint Injections for Arthritis and Inflammation
When the inside of the knee is inflamed, a joint injection delivers anti-inflammatory medication right where it hurts. Because the medication goes straight to the source, many patients feel calmer, looser movement within a few days.
For some patients, a lubricating injection is a better fit. These add cushioning to a joint that has lost its natural glide, which can make walking and climbing stairs feel smoother. Dr. Greenspan will talk through which type makes sense for your knee.
Relief from injections is not always permanent, and that is normal. The goal is to quiet the pain enough that you can move, sleep, and stay active while you build a longer-term plan.
Radiofrequency Ablation for the Nerves Around the Knee
Sometimes the pain keeps coming back no matter what you try. In those cases, the nerves carrying pain signals away from the knee can be targeted directly.
Radiofrequency ablation uses gentle heat to quiet those specific nerves. It does not fix the arthritis, but it can turn down the pain the knee is sending to your brain, often for many months at a time. For patients who are not ready for surgery or want to avoid it, this can be a turning point.
Regenerative Medicine for the Right Candidate
Some patients want an approach that works with the body’s own repair process instead of against it. Our regenerative medicine treatments are a non-surgical option for select patients dealing with joint and soft tissue pain.
This is not right for everyone, and we will tell you honestly whether it fits your situation. Regenerative care is typically not covered by insurance, so we offer some of the lowest cash prices anywhere, with clear pricing and no surprise fees. You can see details on our regenerative medicine page.
Who Is a Good Candidate for Non-Surgical Knee Care?
Not every knee needs the same plan, which is exactly why an honest evaluation matters. These treatments are often a strong fit if you:
- Have knee arthritis or chronic knee pain that has lasted months
- Were told you may eventually need a knee replacement
- Want to delay or avoid surgery
- Have pain that keeps returning after rest, bracing, or physical therapy
- Are not a surgical candidate right now for other health reasons
Because this is a single-physician practice, the doctor who evaluates your knee is the same doctor who treats it. You get a straight answer about what is likely to help, not a push toward the most expensive option.
Why Avoid or Delay Knee Surgery?
Knee replacement helps the right patients, and sometimes it truly is the best path. But it is major surgery, with anesthesia, weeks of rehab, and no guarantee that every ache disappears afterward.
Trying targeted non-surgical treatment first costs you very little and can buy you years of comfort. If you do eventually choose surgery, you will go in knowing you explored the alternatives rather than wondering what you skipped.
That middle ground, more targeted than pills and physical therapy but far less invasive than an operation, is where many knee patients find their best relief.
Why Patients Choose American Pain Institute
Knee pain is personal, so your care should be too. As a private practice with one physician, we offer something larger clinics often cannot. You see Dr. Greenspan at every visit, and your plan is guided by the same doctor who already knows your knee.
He reviews your history and imaging before your first appointment, so you start with answers instead of a clipboard. From there, your treatment is built around your diagnosis, your activity level, and what you actually want to get back to doing. You can explore every procedure on our pain management services page.
