If your knee hurts every time you climb stairs, get up from a chair, or walk more than a few minutes, you already know how much osteoarthritis can shrink your daily life. Most people don’t get the pain checked out until it starts stopping them from doing things they actually want to do, like playing with their kids or walking to the market without wincing.
At ACRT BD in Baridhara, Dhaka, we see this pattern almost every week. Someone in their 40s or 50s comes in after months, sometimes years, of managing knee pain with painkillers and rest. By the time they walk through our door, they’re usually asking one question: is surgery the only option left?
It isn’t. For a large number of patients, Platelet-Rich Plasma (PRP) therapy and Extracorporeal Shockwave Therapy (ESWT) offer a real alternative. Not a miracle cure, and not right for everyone, but a treatment path worth understanding before you commit to a knee replacement.
What’s Actually Happening Inside an Osteoarthritic Knee
Osteoarthritis isn’t just “wear and tear,” even though that’s how most people describe it. The cartilage that cushions your knee joint breaks down over time, so bone starts rubbing closer to bone. This triggers low-grade inflammation, which is why your knee feels stiff in the morning, swells after a long day on your feet, or aches when the weather changes.
Common triggers we see in our clinic:
Age past 45, previous knee injuries (even old sports injuries from 20 years ago), being overweight, jobs that involve a lot of standing or squatting, and family history of arthritis. Rickshaw pullers, garment factory workers, and people who spend hours sitting cross-legged for prayer or work often develop knee problems earlier than expected in Bangladesh specifically.
The mistake we see most often: people wait too long. They try home remedies, over-the-counter pain relievers, and rest for a year or two, and by the time they come in, the cartilage damage has progressed further than it needed to. Earlier intervention with regenerative therapy tends to produce better results than waiting until the joint is severely degraded.
How PRP Therapy Works for Knee Osteoarthritis
PRP starts with a small blood draw from your own arm, similar to a routine blood test. That blood goes into a centrifuge, which spins it at high speed to separate out the platelet-rich plasma from the rest of the blood components. Platelets carry growth factors that play a direct role in tissue repair and reducing inflammation.
Once separated, we inject the concentrated PRP directly into your knee joint under sterile, guided conditions. The whole process, from blood draw to injection, usually takes under an hour.
Because it uses your own blood, there’s no risk of an allergic reaction or rejection, which is one reason PRP has become a preferred option over some older treatments like cortisone injections. Cortisone can offer quick relief but tends to wear off fast and, with repeated use, can actually weaken cartilage further. PRP works differently. It doesn’t just mask pain. It supports the joint’s own repair processes.
That said, PRP isn’t a one-session fix for most people. We typically recommend a series of 2 to 3 injections spaced a few weeks apart, depending on how advanced the osteoarthritis is and how your joint responds after the first session.
You can read more about how we approach PRP for joint and tendon pain generally on our PRP therapy for joint and tendon pain page.
How Shockwave Therapy (ESWT) Treats Knee Pain
Extracorporeal Shockwave Therapy sounds intimidating, but the actual experience is straightforward. A handheld device delivers focused acoustic wave pulses through your skin directly to the affected area of your knee. No needles, no incisions, no anesthesia required.
Those shockwaves do a few specific things inside the joint. They stimulate blood flow to the area, which speeds up the body’s natural healing response. They also help break down calcified deposits that build up around damaged tissue over time, and they trigger the release of growth factors similar to what happens with PRP, just through a mechanical rather than biological pathway.
A typical ESWT session for knee osteoarthritis runs about 15 to 20 minutes. Most patients feel a tapping or pulsing sensation during treatment, mild discomfort at most, and walk out immediately afterward. There’s no downtime. You can go back to work or your normal routine the same day.
We usually recommend a course of 4 to 6 sessions, spaced about a week apart. Results build gradually. Some patients notice reduced stiffness after the second or third session, while others need the full course before feeling a meaningful difference. For a closer look at how shockwave therapy works across different joints, our Extracorporeal Focused Shockwave Therapy page covers the mechanism in more detail.
Why We Often Combine PRP and Shockwave Therapy
On their own, both treatments help. Combined, they tend to work faster and more thoroughly for moderate to advanced knee osteoarthritis, because they’re targeting the problem from two different angles.
Shockwave therapy improves blood flow and loosens the surrounding tissue first. PRP then delivers concentrated growth factors into a joint environment that’s already primed to use them. In our clinical experience, patients who get ESWT sessions before or alongside their PRP injections often report better and longer-lasting relief than PRP alone.
This isn’t the right combination for every patient though. Someone with mild, early-stage osteoarthritis might do fine with shockwave therapy alone. Someone with more advanced joint damage might need PRP paired with viscosupplementation instead. This is exactly why a proper in-person assessment matters more than following a generic protocol. You can learn about our joint lubrication option on the viscosupplementation page if that’s part of what gets recommended for you.
Who Is a Good Candidate, and Who Isn’t
Not everyone with knee pain needs PRP or shockwave therapy, and being upfront about that is part of doing this job properly.
Good candidates typically include people with mild to moderate osteoarthritis confirmed by X-ray or clinical exam, patients who want to delay or avoid knee replacement surgery, active adults dealing with chronic knee pain that hasn’t responded well to rest and basic pain medication, and people who prefer a non-surgical route before considering more invasive options.
These therapies are usually not the right fit for patients with severe bone-on-bone arthritis where the joint space has essentially disappeared, active infections in or near the knee, certain blood disorders that affect platelet function, or pregnant patients (for shockwave therapy specifically near the treatment area).
If you’re dealing with severe, advanced osteoarthritis, it’s worth reading our comparison on regenerative therapy versus surgery to understand where the line actually sits for your specific situation. Age alone doesn’t disqualify anyone. We’ve treated patients well into their 70s. What matters more is the actual condition of the joint, which is something we determine after an in-person exam, not a phone consultation.
What Results Actually Look Like
We want to set realistic expectations here rather than oversell anything.
Most patients start noticing reduced pain and stiffness within 2 to 4 weeks after starting treatment, though this varies by individual. Full benefits from a combined PRP and shockwave protocol usually build over 2 to 3 months as the tissue repair process continues in the background, even after your last session.
This isn’t permanent in the sense of a cure. Osteoarthritis is a degenerative condition, and these therapies work by supporting your body’s repair mechanisms and reducing inflammation, not by regrowing lost cartilage from scratch. Many patients get a year or more of significant relief from one treatment course, then return for a maintenance session if symptoms start creeping back.
What we hear most often from patients afterward isn’t “my knee is perfect now.” It’s things like being able to climb stairs without gripping the railing, sitting through a full prayer without their knee locking up, or walking to work without needing a break halfway. Those are the outcomes that actually change daily life.
A Common Mistake: Waiting Until You Can’t Walk
We treat a lot of patients who tell us some version of the same story: “I thought it would get better on its own,” or “I didn’t want to spend money until I really had to.”
The problem with waiting is that osteoarthritis doesn’t pause while you decide. Cartilage damage that could have been managed at an earlier stage often progresses to the point where regenerative options become less effective, and surgery starts looking like the only remaining choice. If you’ve had knee pain for more than a few weeks that isn’t improving with rest, it’s worth getting it looked at properly rather than guessing at home remedies.
If you’re weighing whether it’s time to get your knee replacement delayed further with regenerative options, our article on whether knee replacement can be delayed walks through that decision in more detail. We also cover the difference between pain that comes from age versus an old injury on our knee pain: age versus injury page, which is a distinction that changes how we approach treatment.
What to Expect at Your First Visit
Your first appointment at ACRT BD starts with a physical exam and a review of your symptoms, medical history, and any existing imaging you have, like X-rays or MRI scans. If you don’t have recent imaging, we’ll typically recommend getting it done so we have an accurate picture of how advanced the joint damage actually is before recommending a treatment plan.
From there, we’ll walk you through which combination of PRP, shockwave therapy, or other options like viscosupplementation actually fits your case, along with a realistic timeline and cost breakdown. We don’t push a one-size-fits-all package. Some patients need three shockwave sessions and nothing else. Others need the full combined protocol.
You can book a consultation directly through our chronic pain consultation booking page, or reach us on WhatsApp at 01977656237 if you’d rather ask questions before committing to an appointment. Our clinic is located at House-190 (ground floor), Lane/Road-2, Baridhara DOHS, Gulshan, Dhaka-1206.
Living with knee pain long enough to accept it as normal isn’t something you have to do. If it’s been bothering you for weeks or months, get it looked at. The earlier we catch it, the more options you have.
