Background
A genicular nerve injection can be used to treat knee osteoarthritis pain with or without steroid. The addition of steroid provides a longer effect but this wanes between 4-8 weeks. With lidocaine alone the effect wanes by 2-4 weeks. However clinically significant relief is only maintained for two weeks. Clinical improvements in functional capacity persist for one week in both options. The use of corticosteroid to enhance a peripheral nerve block remains controversial. [1]
Anatomy
Indications
Contraindications
Technique
Ultrasound Guided
- 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.
Non-ultrasound Guided
