- Position: Supine with pillow under the knee.
- The genicular nerves (superior lateral, superior medial, and inferior medial) run next to the genicular arteries next to the periosteum of the distal femoral condyle and medial tibial metaphysis.
- The nerves may be unidentifiable which does not make the procedure contraindicated
- confirm vessel location using colour doppler.
- Deposit 2mL next to each genicular artery, for a total of 6mL, plus steroid if using.
