{Abstract}: Lumbar sympathetic blocks (LSBs) are used to treat sympathetically mediated pain in the lower extremities, kidneys, ureters, and genitals. LSBs use local anesthetic to block the sympathetic system to modulate pain response. In this case report, an avid runner was diagnosed with synovial plica syndrome. His pain was refractory to arthroscopic plica excision, physical therapy, nonsteroidal anti-inflammatory drugs, and intraarticular steroid injections. He received 3 rounds of LSB resulting in significant and sustained pain relief. This case suggests that LSB successfully treated knee pain from synovial plica syndrome and there may be a sympathetic component to this disease state.
