  • moderate to severe refractory prosthetic joint pain
  • ruled out implant infection, loosening or any surgically explainable cause of pain
  • used 100 – 300 u Botox in 5 mls saline
  • Confirmed joint penetration by ability to aspirate joint fluid

  • average 3 shots
  • if failed at 100 units worked up to 200-300
  • average 3 injections over average 1 year followup.
  • at 3 -4 months after injection, 57% patients reported 50% reduction in daytime pain
