Is This For You?

Who is Arthrosamid For? Recognising the Ideal Candidate

Arthrosamid is highly effective for a wide demographic of patients from active individuals wanting to maintain their athletic lifestyle to older patients seeking a pain-free retirement without surgical risks.

You require a specialist assessment if you experience:

  • Diminishing Returns from Other Treatments:
    - Corticosteroid or hyaluronic acid injections no longer provide lasting relief.
  • Desire to Avoid Surgery:
    - You wish to delay knee replacement, are deemed too young for implants, or have medical comorbidities that make anaesthesia risky.
  • Constant Daily Pain:
    - You struggle to walk short distances without a limp or require walking aids.
  • Profound Joint Stiffness:
    - Bending your knee to put on shoes is incredibly difficult; stiffness after sitting is severe.
  • Loss of Quality of Life:
    - You are actively cancelling holidays or giving up low-impact sports like golf or cycling.
Understanding Your Condition

Where Arthrosamid Fits: The Orthopaedic Treatment Ladder

A responsible orthopaedic approach ensures treatments are scaled according to the severity of your cartilage loss.

1
Early Management
  • Targeted physiotherapy, weight management, and activity modification.
2
Medical Interventions
  • Use of NSAIDs and temporary ultrasound-guided corticosteroid injections for acute inflammation.
3
The Arthrosamid Window
  • When osteoarthritis progresses and traditional injections fail, Arthrosamid bridges the gap, providing years of relief and successfully delaying prosthetic implants.
3
The Surgical Threshold
  • When all joint-preserving options are exhausted, and cartilage loss is absolute, knee replacement becomes the final step.
Where Mr. Sobti Practices

The Core Benefits of Arthrosamid Therapy in London

Clinical studies demonstrate that a single Arthrosamid injection provides significant pain reduction within weeks.

Proven Efficacy

Supported by more than two decades of rigorous scientific research in treating osteoarthritis safely. Exceeds the Minimal Clinically Important Difference (MCID) scoring metrics.

Long-Lasting Relief

Clinical data shows sustained, significant pain reduction maintained up to and beyond five years after a single injection.

Without Surgery

Avoid the profound physical trauma, hospitalization, infection risks, and exhaustive 6-to-12-month rehabilitation protocols associated with total knee replacement.

When To Seek Help

A Patient-Centred Treatment Philosophy

Preservation First

Surgery is never the default first step. Biological and biomechanical joint preservation is prioritized.

Evidence-Based Innovation

Mr. Sobti exclusively utilizes treatments supported by rigorous clinical data, such as the two decades of research backing Arthrosamid.

Tailored Recovery

Integrating advanced therapies customized to restore you to the specific hobbies, work, and sports you love.

Treatment Options

What is Arthrosamid®? The Science of Permanent Hydrogel

For decades, non-surgical options were limited to temporary steroid injections or short-acting hyaluronic acid. Arthrosamid completely redefines orthopaedic medicine.

The Hydrogel Technology

Arthrosamid is the first and only approved injectable treatment consisting of a 2.5% cross-linked polyacrylamide hydrogel.

Unlike traditional injections that are quickly absorbed and flushed out by the body, this hydrogel is permanent and will not degrade over time.

The Biological Integration

When injected, the hydrogel permanently combines with the knee’s synovial tissue (the inner lining of the joint capsule).

It significantly thickens the protective lining, acting as a permanent, physical shock absorber that spaces the joint and reduces bone-on-bone friction.

Timeline Journey

The Patient Journey: Diagnosis to Day of Injection

Delivering Arthrosamid requires anatomical precision. Mr. Sobti’s protocol ensures maximal safety and efficacy.

Step 1: The Expert Consultation

  • An unhurried discussion of your symptom history, paired with a thorough physical examination assessing gait and joint effusion.

Step 2: Advanced Diagnostic Imaging

  • Rapid-access weight-bearing X-rays or MRI scans to precisely grade cartilage loss and confirm Arthrosamid suitability.

Step 3: Collaborative Planning

  • Reviewing scans in plain English. Mr. Sobti will explain exactly how the hydrogel will interact with your specific joint anatomy.

Step 4: The Procedure Preparation

  • Administered in a sterile outpatient clinical setting. The knee is thoroughly cleaned and a local anaesthetic is applied.

Step 5: Precision Injection

  • Utilizing ultrasound guidance, the 6ml hydrogel is delivered with pinpoint accuracy directly into the joint cavity in under 30 minutes.

Arthrosamid Recovery Week by Week

Recovery is a partnership between the biological integration of the hydrogel and your commitment to brief, sensible rehabilitation.

Days 1 to 3 (Immediate Post-Injection):

Walk out of the clinic unassisted. Temporary mild swelling or a sensation of "fullness" is normal. Focus on resting and avoiding unnecessary strain.

Weeks 1 to 2 (Integration Phase):

Avoid heavy lifting, deep squatting, and high-impact exercises.
- Allow the hydrogel to successfully weave into the synovial joint tissue without displacement.

Weeks 4 to 12 (Symptom Relief):

The biological cushioning effect matures over this window.
- Joint stiffness drastically decreases; significant pain relief is clinically realized.

Months 3 and Beyond (Returning to Life):

Fully cleared to return to normal daily activities.
-Resume recreational sports, golf, and travel without chronic osteoarthritic pain.

Honest Care: Benefits, Risks, and Important Considerations

Trust is built on absolute transparency. Every patient must be fully informed of the clinical profile of any joint intervention.

01

Advantages of the Clinical Approach:

  • Surgical Avoidance: Complete elimination of invasive trauma and the requirement for hospital stays.
  • Structural Preservation: Targeted protection of your existing natural bone and joint cartilage .
  • Superior Longevity: Sustained therapeutic relief that consistently outperforms alternative injectable treatments currently available.
02

Understanding the Clinical Profile:

  • Temporary Swelling: Mild, transient discomfort at the injection site can occur, resolving within a few days with simple ice and rest.
  • Infection Risk: As with any injection, there is a microscopic risk of infection, heavily mitigated by strict adherence to sterile clinical techniques.
  • Delayed Onset: Integration takes time. Full efficacy is usually judged at the 12-week mark; it is not an instant "magic bullet."
