|---|---|---|---|---|---|
| How it works | Strengthens muscles, reduces joint load | Steroid calms inflammation; HA adds lubrication | Heat disables pain-carrying nerves | Blocks abnormal vessels feeding synovial inflammation | Replaces joint surfaces with implants |
| Invasiveness | None | Needle in joint | Needles near nerves | Pinhole catheter access | Major surgery |
| Anesthesia | None | Local | Local ± light sedation | Local + twilight sedation | General or spinal |
| Recovery | None | 1–2 days | Few days | Most resume normal activity in days | 6 weeks to 3+ months |
| Typical duration of relief | Ongoing with adherence | Weeks to a few months | About 6–12 months; nerves may regrow | Studies report relief lasting 1–2+ years in many patients | Often 15–20+ years |
| Treats underlying inflammation? | Indirectly | Temporarily (steroid) | No — blocks pain signal | Yes — targets synovitis blood supply | Removes diseased joint |
| Best suited for | All stages, first line | Flares, early-to-moderate OA | Moderate–severe OA, non-surgical patients | Mild–moderate OA after failed conservative care | Severe, bone-on-bone OA |
| Key risks | Minimal | Cartilage effects with repeated steroids, glucose spikes | Numbness, temporary soreness | Temporary skin discoloration, access-site bruising | Infection, clots, stiffness, revision surgery |
| Preserves native knee? | Yes | Yes | Yes | Yes — does not preclude future surgery | No |
Bars show a simplified favorability rating (more = more favorable) for general education. Durations are typical ranges from published literature; individual results vary.
