Two Orthopedic Giants, Two Single-Shot Options
Gel-One (Zimmer Biomet) and Monovisc (Anika Therapeutics) are both single-injection HA treatments from orthopedic device leaders. They differ in source: Gel-One is avian-derived (chicken combs), while Monovisc uses bacterial fermentation and is safe for avian-allergic patients.
Side-by-Side Comparison
| Factor | Gel-One | Monovisc |
|---|---|---|
| Manufacturer | Zimmer Biomet | Anika Therapeutics |
| Volume | 3 mL | 4 mL |
| Molecular weight | High (500-730 kDa) | Higher (1-2.9M Da) |
| Source | Avian (chicken combs) | Non-avian (bacterial) |
| Self-pay | $700-$1,000 | $700-$1,100 |
| Duration | 4-6 months | Up to 6 months |
Key Differences
Gel-One Advantages
- Smaller volume - 3 mL may mean less swelling
- Slightly lower cost - Marginally cheaper
Monovisc Advantages
- Higher molecular weight - Potentially better cushioning
- Anika Therapeutics backing - Dedicated orthopedic joint health expertise
Allergy Note
Gel-One is contraindicated for bird/egg allergies (derived from chicken combs). Monovisc is safe for avian-allergic patients — it is produced through bacterial fermentation, not from animal sources. If you have avian allergies, Monovisc or Durolane are appropriate single-injection options.
Making Your Decision
Choose Gel-One if:
- You prefer smaller injection volume
- Your provider stocks Zimmer Biomet products
- Slightly lower cost matters
Choose Monovisc if:
- You want higher molecular weight
- Your insurance prefers Anika Therapeutics products
- You’ve used Orthovisc successfully before
The Bottom Line
Both are solid single-injection options from orthopedic leaders. The differences are subtle—volume preference and insurance coverage will likely determine your choice.
