The Role of Inflammation in OA
• Inflammation secondary to cartilage degradation
• Morphological changes in OA synovium
- Usually mild to moderate
- At times comparable to rheumatoid arthritis (RA)
- Characterized by increased numbers of:
• Inflammatory mononuclear cells
• Activated T-cells and B-cells

The Chondrocyte in Inflammation
• Pro-inflammatory cytokines and mediators produced by chondrocytes act within cartilage
- Autocrine
- Paracrine
- Promote catabolism

• Pro-inflammatory cytokines
- Interleukin-1
- Tumor necrosis factor-
- Interleukin-6
- Interleukin-8

The Chondrocyte in Inflammation
• Nitric oxide (NO) promotes catabolism
• NO can
- Inhibit synthesis of cartilage macromolecules
- Enhance activity of matrix metalloproteases
- Reduce the synthesis of anti-inflammatory cytokines
• Increase levels of prostaglandins and leukotrienes, possibly promoting catabolism

Functions of Hyaluronic Acid (HA)in the Normal Joint
• Hyaluronic acid (HA) plays a key role in homeostasis
of the normal joint
- Macro-homeostasis – the rheological environment
- Mini-homeostasis – the fluid environment
- Micro-homeostasis – the chemical environment

Macro-homeostasis: HA in Synovial Fluid (SF)
• Highly influences intercellular matrices of joint soft tissues
• Unique combination of elasticity and viscosity
• Hyaluronan responsible for elastoviscous properties
• Elastoviscosity critical for joint function

• Designed as a synovial fluid prosthetic device
• A series of three injections can provide pain relief for months
• Generally well tolerated in trials and clinical practice

Role of Molecular Weight – Pain Receptors
• Objective
- Compare the effects of commercial viscoelastic substances with different molecular weights on the discharges of joint nociceptors evoked by movement of the inflamed rat knee joint
• Methods
- Electrical activity of median articular nerve
- Inflammation – kaolin and carrageenan
- Mechanical stimulation – controlled joint rotation
- Sodium hyaluronate injected in joint cavity (MW <1,000,000 & <2,000,000 and high MW ~6,000,000 [Hylan G-F 20])
- Impulse discharge before and after injection measured with movement

Role of Molecular Weight – Pain Receptors
• Results
- SYNVISC® (MW ~6,000,000) significantly reduced the number of nerve impulses evoked by movement after 1 hour.
- MW <2,000,000 hyaluronan solutions were slightly faster and had a weaker effect after 30 minutes.
- MW <1,000,000 did not significantly reduce mean impulse frequency.
• Conclusion
- “…it is to be expected that high MW hylan solutions will have more pronounced analgesic effects on human joint pain than hyaluronan solutions of lower MW.”

• No systemic adverse events
• Forty-two transient local reactions noted in 28 patients (no sequelae)
• Rate of local reaction in this study: 2.7% of injections, 8.3% of patients
• Local reaction does not predict treatment failure
- 69% still clinically improved

Efficacy and Adverse Events
• The majority of joints (69%) experiencing local reaction were considered clinically improved
• Of 32 joints in which a local adverse event occurred, 21 (66%) went on to receive subsequent SYNVISC® injections

Pain and/or swelling 39 (2.2) 37 (7.2)after SYNVISC® injection
•The ratio of local reactions among female and male patients was 2:1, the same ratio as the entire OA population.
• Clinical improvement was noted in the majority of patients.
•There were no sequelae following local reactions.
511 patients received 1,771 SYNVISC® injections in 559 knees

Safety Experience – Local Reactions
• Incidence rate ~ 2–3% of injections or 7–8% of patients
• Most occur within 1–2 days of injection
• Typically resolve spontaneously within a week
• Efficacy not necessarily impacted by local reaction

Worldwide Postmarketing Safety Experience
• Spontaneous reports of local reactions (e.g., pain, swelling, and/or effusion)
• Variable synovial fluid cell counts (some exceeding 50,000 cells/mm3)1
• Treatments included rest, ice, heat, elevation, simple analgesics, NSAIDs, intra-articular corticosteroids, and rare reports of arthroscopic debridement.1
