Arthrosamid Injection in Toronto: A New Option for Lasting Relief from Osteoarthritis

Osteoarthritis breaks down joint cartilage over time, leading to pain that doesn’t just flare during a workout – it lingers through everyday life. For many in Toronto, it means waking with stiff knees, struggling to squat, climb stairs, or even take a long walk. Common symptoms like inflammation, decreased mobility, and joint stiffness don’t just affect joints – they limit independence, disrupt routines, and erode overall well-being. Hundreds of thousands of Canadians face this degenerative condition daily, and traditional treatments often fall short of delivering lasting comfort. Enter Arthrosamid injection – Toronto’s newest breakthrough in managing osteoarthritis pain.

 

When the Relief Doesn’t Last: Why Traditional Osteoarthritis Treatments Fall Short

For years, people managing knee osteoarthritis in Toronto have turned to conventional options like painkillers, corticosteroid injections, and hyaluronic acid treatments. These methods can ease symptoms for a while – but they don’t address the degenerative process of osteoarthritis or produce long-lasting improvement.

Short-Term Fixes That Don’t Stick

• Pain medications – such as NSAIDs or acetaminophen – reduce inflammation and discomfort but wear off after a few hours, requiring repeated use and offering no structural benefit to the knee joint.
• Corticosteroid injections deliver rapid relief by suppressing inflammation, yet the effects typically fade within weeks or a few months. According to a 2015 study in JAMA, long-term steroid injections may even contribute to cartilage volume loss.

Where Conventional Solutions End, Arthrosamid Begins

Arthrosamid is changing the expectations for injection therapy. Unlike HA or steroids, it’s not a temporary filler or a short-lived anti-inflammatory fix. This polyacrylamide hydrogel forms an integrated cushion inside the knee, creating a long-lasting effect without the need for repeat injections every few months.

For individuals in Toronto searching for a new direction in osteoarthritis management, Arthrosamid introduces a science-backed therapeutic shift- redefining longevity, durability, and joint support from within.

 

 

Arthrosamid Injection Toronto: Redefining Knee Osteoarthritis Treatment

What is Arthrosamid?

Arthrosamid is a non-biodegradable polyacrylamide hydrogel injection designed for the treatment of knee osteoarthritis (OA). Unlike traditional injections, it doesn’t just manage inflammation temporarily- it transforms the joint environment. This single-dose, intra-articular therapy creates a durable cushioning effect within the knee, improving mobility and reducing pain over the long term.

Health Canada has approved Arthrosamid as a Class III medical device. Developed in Denmark, and tested across European centres in double-blind clinical trials, this hydrogel has been used in more than 20,000 knees globally. In Toronto, Dr. Joseph Menna, a board-certified orthopaedic surgeon, now offers the Arthrosamid injection exclusively at Push Pounds Sports Medicine Clinic – the first centre in Canada to make this treatment available.

Composition: Polyacrylamide Hydrogel

The active component in Arthrosamid is non-absorbable polyacrylamide hydrogel, made of 2.5% cross-linked polyacrylamide and 97.5% water. This creates a highly stable, viscoelastic substance that integrates safely into the knee joint capsule. Once injected, the hydrogel does not degrade like corticosteroids or hyaluronic acid do, maintaining its mechanical integrity over the years.

How It Works

After a single injection into the synovial cavity of the knee, Arthrosamid permanently supplements the joint’s buffer system. The hydrogel binds with the synovial membrane, forming a protective and lubricating layer that absorbs mechanical shock and enhances joint biomechanics. This rehydration of the intra-articular space reduces nociceptive pain signals and friction between cartilage surfaces, creating a smoother glide with motion.

The effect is not temporary. European follow-up studies, including the ROSE study published in the journal Cartilage (2021), confirm sustained improvement in pain relief and function beyond 2 years in patients receiving a single treatment.

What Sets Arthrosamid Apart from Traditional Injection Therapies

• Single Treatment, Long-Term Results: One injection shows durable relief lasting 2+ years, as compared to corticosteroid or hyaluronic acid injections that often require repeat application every 3–6 months.
• Mechanical and Biological Integration: Arthrosamid physically integrates with the synovial membrane, unlike viscosupplements that dissipate over time.
• No Cartilage Breakdown: Unlike steroids that accelerate cartilage degeneration, Arthrosamid does not degrade joint surfaces.
• Alternative to Surgery: Many patients use Arthrosamid to avoid or delay total knee replacement, particularly those with moderate to severe osteoarthritis who aren’t surgical candidates or are seeking non-surgical options.

Patients from across North America – notably the United States – are traveling to Toronto for same-day Arthrosamid procedures with Dr. Menna. With no need for overnight stays or prolonged recovery, this therapy attracts individuals who want fast access to next-generation osteoarthritis care without crossing into surgical intervention.

Experience Lasting Relief: How Arthrosamid Boosts Knee Joint Health in Toronto

Living with knee osteoarthritis means dealing with chronic discomfort that affects every step, stair, and quiet moment. Arthrosamid injection in Toronto changes this dynamic entirely. Thousands across Europe have already experienced the transformation. Now, for the first time in Canada, the same therapeutic breakthrough is available through Push Pounds Performance Wellness. Here’s what the therapy delivers.

Unmatched Duration of Pain and Symptom Relief

Unlike corticosteroid injections, which typically offer only a few weeks to a few months of relief, a single Arthrosamid injection delivers sustained improvement for years. Clinical trials show significant pain reduction maintained at 2 years post-injection. This outcome results from Arthrosamid’s non-biodegradable polyacrylamide hydrogel structure, which integrates with joint tissue and does not degrade over time.

Inflammation Diminishes at the Source

Chronic inflammation in the synovial membrane plays a central role in the pain cycle of osteoarthritis. Arthrosamid targets this inflammation directly. Once injected into the knee joint, it integrates into the synovial lining. This alters the tissue environment and reduces pro-inflammatory mediators, which produces noticeable reductions in swelling and pain perception.

Improved Joint Mobility Restores Normal Activity

Functional mobility isn’t simply about the absence of pain—it’s about freedom of movement. As the hydrogel cushions the knee joint and calms inflammatory processes, users report smoother, more stable movement. This increase in range of motion allows for everyday actions—rising from a chair, climbing stairs, walking longer distances—without the fear of destabilizing pain.

No Operating Rooms. No General Anesthesia. No Hospital Stay.

Patients receive Arthrosamid treatment in a clinical setting without the risks or recovery burden of surgery. The injection is performed under local anesthetic using image guidance for precise delivery to the joint space. The entire procedure is outpatient-based, with most patients walking out of the clinic within an hour.

Simplicity Without Compromise

• Single treatment session: No repeat visits required for ongoing effect.
• No incisions: The hydrogel is administered through a fine needle.
• Minimal downtime: Most resume normal activity within 24 to 48 hours.

How would your day look if joint pain stopped dictating your choices? Arthrosamid injection in Toronto offers not just relief – but renewal.

Inside Arthrosamid: How This Injection Fights Knee Osteoarthritis at the Root

What Happens When the Needle Hits the Joint

Arthrosamid works right where osteoarthritis causes damage – inside the knee joint. Administered as a single injection, it’s delivered directly into the intra-articular space of the affected knee. The procedure takes place in a clinical setting using ultrasound or image guidance to ensure precise placement of the hydrogel-based product.

Bonding with the Synovial Membrane

Once injected, Arthrosamid interacts with the synovial lining of the joint – this is where the transformation begins. Unlike traditional injectables that merely lubricate, the polyacrylamide hydrogel chemically integrates with the synovium. This bonding process allows it to create a resilient, soft-layered cushion within the joint space.

No Breakdown, No Repeat Injections

With hyaluronic acid-based injections, the relief fades within months because the substance naturally degrades in the body. Arthrosamid doesn’t share that weakness. Composed of 97.5% water and 2.5% cross-linked polyacrylamide, it remains stable and intact long-term. One injection delivers sustained joint support without the need for repeated administration every few months.

By Reducing Friction, It Reduces Pain

Think about how sandpaper feels on your skin. That’s the level of friction bone-on-bone movement can cause in an arthritic knee. Arthrosamid reduces that friction significantly. Bound into the synovial tissue, the hydrogel acts as a semi-permanent lubricant. It absorbs the mechanical load of movement, lowers stress on cartilage surfaces, and decreases the chronic inflammation responsible for pain.

• Delivered into the joint space: The hydrogel reaches the heart of the inflammation and mechanical wear.
• Synovial bonding: Physically integrates with the joint liner, forming a bio-compatible cushion.
• Non-degradable: Maintains its structure and function over the long term.
• Reduces inflammation: Less friction means lower release of inflammatory cytokines and slowed cartilage breakdown.

Engineering Pain Relief That Lasts

This isn’t surface-level relief. Arthrosamid modifies the internal environment of the joint by combining physical cushioning with anti-inflammatory effects. Clinical data show that patients experience measurable pain reduction and increased mobility for 12 months or longer after a single treatment. When looking for arthrosamid injection Toronto specialists offer, this is the outcome they aim to deliver—a quieter, smoother, more functional knee joint.

Arthrosamid Injection in Toronto: A True Alternative to Knee Replacement Surgery

Who benefits most from Arthrosamid injections?

Not every knee pain case leads to the operating room. Arthrosamid is designed for adults with knee osteoarthritis who haven’t responded to conventional treatments like physiotherapy, NSAIDs, or hyaluronic acid injections. It’s especially suited to individuals seeking to avoid the risks, long healing periods, and irreversible changes associated with total knee replacement.

Patients often turn to surgery when daily activities—climbing stairs, walking a few blocks, or even standing—become difficult. Arthrosamid offers a detour. Rather than replacing the joint, the injection enhances its function, reduces pain, and delays or removes the need for invasive surgical procedures.

When surgery doesn’t fit your life, Arthrosamid does

• Too active to stop moving? If you’re not ready to hit pause for months of surgical recovery, Arthrosamid can fit your pace.
• Worried about surgical risks? Arthrosamid avoids the bleeding, infection, and anesthesia complications common with surgery.
• Already had one knee replaced? Patients often seek to delay the same path for the other knee and use Arthrosamid to extend that timeline significantly.

Compare the timelines: Surgical downtime vs. Arthrosamid recovery

Full recovery after total knee replacement takes approximately 6 to 12 months, depending on age, physical condition, and adherence to post-op rehab. Most patients require intensive physiotherapy, time off work, and assistance with walking for several weeks. Complications may extend this period even further.

Contrast that with Arthrosamid: one outpatient injection, no hospital stay, and minimal disruption to your week. Most patients resume normal routines within days. There’s no incision, no implant, and no physiotherapy schedule to manage. Just gradual, consistent relief—often within weeks, and lasting up to 2 years or more according to published clinical trials.

Preserve your natural knee, extend your active life

Every knee replacement removes living tissue and replaces it with metal and plastic. Arthrosamid does the opposite. It works with your joint’s existing structure to restore viscosity, cushion movement, and reduce inflammatory pain. That’s how it extends joint integrity instead of removing it.

Think about the value of preserving your body as long as possible. Walking unaided. Exercising at your own pace. Playing with your grandchildren. Arthrosamid keeps that picture intact. It’s available now in Toronto and changing how knee osteoarthritis is treated, one joint at a time.

Minimal Downtime. Fast Recovery. Real Possibility.

Arthrosamid injection in Toronto offers more than pain relief—it’s designed to fit into your life with minimal disruption. No hospital stays. No drawn-out recovery timelines. Just a straightforward procedure and a smooth return to your daily rhythm.

Walk In, Walk Out: In-Office Convenience

The entire procedure takes place in a clinical setting, not a surgical theatre. Patients walk into the clinic, receive their injection under guided precision, and walk out within the hour. General anesthesia isn’t needed, which means there’s no grogginess, no overnight stays, and no waiting on operating rooms.

Recovery in Days, Not Weeks

Most patients resume light activity, such as walking or desk work, within just a few days of receiving the injection. Some report feeling improvements in joint comfort during the first week, while others gradually regain mobility over several weeks. Regardless of the pace, there’s no lengthy rehab program or high-impact physiotherapy required to get started.

No Scalpel, No Stitches, No Problem

• No surgical incisions: The skin stays intact—there’s nothing to heal on the surface, and no stitches needed.
• Minimal aftercare: Post-procedural care typically involves some mild activity restriction for 48–72 hours, but there’s no bandaging or dressing to maintain.
• No general anesthesia: Local anesthetic and ultrasound guidance ensure accuracy and comfort, without general sedation risks.

Imagine reclaiming knee function without scheduling life around surgery. That’s what Arthrosamid offers. If you’re measuring treatment options by how quickly you can get back on your feet, this injection redefines recovery standards.

Decades of Research Back Arthrosamid’s Safety and Efficacy

Extensive Clinical Trials Confirm Long-Term Reliability

Arthrosamid has undergone rigorous evaluations in both European and Canadian settings. The pivotal phase III trial, known as the OA-02 study, involved over 600 patients with knee osteoarthritis across multiple countries. Results published in 2021 showed statistically significant improvement in pain and joint function at 6 and 12 months post-injection, measured by the WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) scores.

Clinical data from Denmark’s leading rheumatology centres reports sustained patient improvement even 24 months after a single 6ml dose. Participants not only noted pain relief but also reported improved mobility and daily function without additional joint procedures.

Established Long-Term Safety Profile

Arthrosamid is composed of a non-biodegradable polyacrylamide hydrogel, which has already seen over 20 years of medical use in urology and aesthetic medicine. In orthopaedic applications, no significant adverse effects have been reported in long-term follow-ups. Post-market surveillance across Europe shows a consistently low incidence of injection-site reactions and no systemic complications.

• OA-01 Pilot Study: 96% of participants completed the trial without complications after one year
• OA-02 Controlled Trial: Less than 1.5% experienced minor localised swelling, which resolved without intervention
• Scandinavian Registry Data: Zero reports of allergic reactions or hydrogel migration among tracked patients

Precision Delivery by Trained Specialists

Arthrosamid injection in Toronto is offered only through specialist-certified clinics. Every procedure is performed under ultrasound guidance, ensuring precise placement within the intra-articular space. This level of accuracy significantly lowers the risk of misplacement or post-injection complications, while maximising therapeutic effect.

Clinicians administering Arthrosamid undergo procedural training set by international standards. Their expertise plays a measurable role in clinical outcomes: one study published in Osteoarthritis and Cartilage Open (2022) found a 43% higher responder rate when injections were delivered by ultrasound-trained specialists compared to general practice.

Looking for real-world insight? Ask your orthopaedic clinic in Toronto how they track patient outcomes after treatment. Every injection tells a story—yours might be next.

Hyaluronic Acid Alternatives: Why Arthrosamid Injection Stands Apart in Toronto

For years, hyaluronic acid (HA) injections have been a common option for managing knee osteoarthritis pain. Though they offer temporary lubrication and some symptom relief, their effect fades, requiring multiple injections over time. Arthrosamid changes that equation.

A Structural Shift in Treatment Philosophy

Unlike hyaluronic acid, which introduces a gel that dissipates within months, Arthrosamid offers a lasting structural intervention. Its unique polyacrylamide hydrogel integrates directly with the synovial lining of the knee joint. Instead of simply adding fluid, it becomes part of the joint’s protective environment.

• Permanent Binding: Arthrosamid’s hydrogel physically adheres to the synovial membrane. This interaction forms a durable layer that cushions the joint and reduces inflammation on a structural level.
• Fewer Repeat Injections: HA often requires administration every 6 to 12 months. Arthrosamid, based on clinical evaluations such as the 2021 ROSE study, sustained meaningful improvement in knee pain for the majority of patients with just one injection after one year.
• No Degradation Over Time: HA naturally breaks down and is absorbed, diminishing its clinical impact. Arthrosamid remains in the joint, unabsorbed, maintaining stability and symptom control without decline in efficacy.

Predictable Relief Without the Cycle of Repeat Intervention

Toronto residents now have access to a treatment that moves beyond short-term patchwork solutions. Instead of planning the next injection before the current one wears off, Arthrosamid users experience steadier, longer-lasting relief—free from the biochemical fluctuations that come with HA degradation.
For individuals seeking dependable symptom control and relief from the cycle of degenerative joint pain, Arthrosamid stands in a category of its own. Which would you rather choose—a temporary fix or a solution designed to stay with you?

Your Arthrosamid Journey: From Consultation to Recovery

Curious about what to expect when receiving your Arthrosamid injection in Toronto? This section walks through every step of your experience—from first contact to post-treatment support. No guesswork, no surprises—just a clear timeline designed to get you moving with less pain.

Initial Consultation and Clinical Assessment

Your journey starts with a one-on-one consultation with a trained specialist. During this visit, you’ll discuss your current symptoms, previous treatments, and how knee osteoarthritis is impacting your daily life. The clinician conducts a physical examination and reviews your medical history in detail to determine if Arthrosamid aligns with your condition and goals.

Diagnostic Imaging—When It’s Needed

If recent imaging isn’t available, your team may order X-rays or MRI scans to better assess the state of your knee joint. These images help rule out advanced joint damage or other conditions that could limit the effectiveness of intra-articular injection therapy.

Precise Treatment Planning

Once confirmed as a candidate, your provider tailors a treatment plan. Timing, aftercare, and support are scheduled to suit your lifestyle. You’ll also receive clear instructions on how to prepare for your injection day, including short-term medication adjustments if necessary.

The Injection—Performed In-Office

The Arthrosamid injection is administered by an experienced physician in a clinical setting. One injection goes directly into the synovial space of the affected knee under sterile conditions. Ultrasound guidance may be used to ensure precise delivery. The entire procedure, from prep to finish, typically takes less than 30 minutes.

Post-Treatment Support and Follow-Up

After your appointment, you can leave the clinic on your own two feet—no crutches, no lengthy rest period. Most patients resume normal activities within one or two days. Follow-up appointments are scheduled to track your response over time, fine-tune your joint care plan, and answer any new questions you may have.

Preparing for Your Appointment

• Wear loose-fitting clothing—This allows easy access to your knee and keeps you comfortable throughout.
• Eat a light meal beforehand—It’s helpful to avoid scheduling your session on an empty stomach.
• Bring a list of current medications—Your clinical team checks for possible interactions and may suggest temporary adjustments.
• Plan light activity for the day—Avoid scheduling intense workouts or long walks immediately after the procedure.

Each step in your Arthrosamid treatment pathway is coordinated with precision—minimizing disruption, maximizing comfort, and aiming for long-term results that reshape your mobility.

Is Arthrosamid Right for You?

People seek out Arthrosamid injection in Toronto for one clear reason—lasting relief from knee osteoarthritis when other treatment paths have failed. But not every case of osteoarthritis qualifies for this type of intervention. So, who stands to benefit most from this injection-based therapy, and who should consider other alternatives?

Ideal Candidates for Arthrosamid

Not everyone experiencing joint pain is the right fit. Arthrosamid has been clinically studied in individuals who:

• Have been diagnosed with mild to moderate knee osteoarthritis.
• Are not suitable candidates—or are not ready—for joint replacement surgery.
• Fall within the age range of 45 to 85, where osteoarthritis often begins to disrupt daily activities.
• Continue to experience discomfort despite having tried other treatments such as oral pain relievers, physiotherapy, or hyaluronic acid injections.

Who Should Consider Other Options?

While Arthrosamid provides relief for many, there are specific conditions where this treatment will not produce the desired results:

• Advanced or severe joint deformities that significantly affect alignment or stability of the knee joint.
• Presence of active joint infections or systemic infections that increase the risk of complications.
• Individuals who have undergone total knee arthroplasty.

Why the Consultation Process Matters

Every Arthrosamid treatment plan begins with a one-on-one consultation. During this session, a specialist will assess medical history, severity of joint damage as seen in imaging scans, and previous treatment responses. This comprehensive assessment leads to a personalized treatment approach that either confirms eligibility or guides the patient toward more appropriate interventions.Thinking about what stage your osteoarthritis is in? Wondering whether you’re too young or too old for injection therapy? These are the kinds of questions that get answered in a consultation. Decisions rely on more than just age or pain level—they come down to structural integrity, symptom progression, and prior treatment history.

Answers You Need About Arthrosamid Injection in Toronto

Will the injection hurt?

Most patients describe the Arthrosamid injection as briefly uncomfortable rather than painful. The procedure involves a single intra-articular injection into the knee joint, typically administered under local anesthesia. The needle used is fine, and the gel-like nature of Arthrosamid minimizes joint capsule distortion. Discomfort lasts only a few seconds during needle insertion, followed by mild pressure once the hydrogel is introduced.

How long does one injection last?

Clinical trials, including the pivotal randomized controlled study published in The Lancet Rheumatology (2022), demonstrate that a single 6 ml injection of Arthrosamid delivers sustained pain relief and improved joint function for up to two years. In a 24-month follow-up, over 70% of patients reported continued symptom improvement. Unlike corticosteroids or hyaluronic acid viscosupplements, its non-biodegradable hydrogel formulation ensures residency within the joint for prolonged periods without being reabsorbed.

Are there any risks or side effects?

Adverse events are rare and typically mild. In post-marketing surveillance and controlled trials, most reported side effects were transient and localized, including:

• Mild joint swelling or warmth in the first 48-72 hours
• Transient stiffness or increased knee sensitivity
• Very low incidence of joint effusion or injection site irritation

Arthrosamid does not provoke an inflammatory response due to its biocompatible nature. No systemic side effects or serious complications have been documented in long-term observational studies across multiple European cohorts.

What is the cost and is it covered by insurance?

Costs vary depending on the clinic, but in Toronto, the price for a single Arthrosamid injection typically ranges between $2,600 to $3,500 CAD. As of now, it is not covered under the Ontario Health Insurance Plan (OHIP). Some private insurance providers may consider partial reimbursement under extended health benefits or medical spending accounts. Patients often use Health Spending Accounts (HSAs) or Flexible Spending Arrangements (FSAs) to offset the expense. Clinics offering Arthrosamid in Toronto can assist with pre-authorization and coverage inquiries.

Ready to Reclaim Your Life Without Surgery?

Living with knee osteoarthritis doesn’t mean surrendering to daily pain or planning your life around future surgery. Arthrosamid injection in Toronto now offers a high-impact, low-disruption alternative—especially for those who’ve tried hyaluronic acid injections or oral medications with little success.

Designed to provide long-lasting symptom relief, Arthrosamid restores knee function by forming a cushion-like barrier in the joint. Once injected, this hydrogel becomes part of the knee lining, reducing inflammation and improving mobility. Clinical trials show sustained improvement in pain scores and physical function for over 12 months post-treatment.

There’s no incision. No weeks of rehab. No long hotel recovery stays. Just a single injection, performed in under 30 minutes, and most patients return to normal activities within days—not weeks.

• Skip the operating room: Arthrosamid works without general anesthesia or surgical prep
• Stay mobile: Resume walking and light movement quickly post-injection
• Regain confidence: Experience reduced stiffness, enhanced range of motion, and fewer pain flares
• Reclaim everyday life: Go back to stairs, strolls, and sport without chronic discomfort limiting your options
