A modified genicular nerve block technique provided pain relief for a patient experiencing persistent pain after total knee arthroplasty (TKA). This approach may be crucial for selecting patients for joint denervation procedures.
Area of Science:
- Pain Management
- Orthopedic Surgery
- Neuroanatomy
Background:
- Persistent pain after total knee arthroplasty (TKA) is a significant clinical challenge.
- Residual innervation to the subchondral bone is a potential cause of post-TKA pain.
- Previous anatomical studies suggested targeting specific quadrants of the distal femur for subchondral bone innervation.
