What is CPSP?

  • Any pain that lasts for more than 3 months after surgery
  • CSPS often has a component related to nerves (neuropathic pain)
  • A common type of CPSP we see is persistent knee pain after knee replacements. Despite a technically perfect knee replacement, studies estimate that approximately 10-30% of patients may still have pain.

  • Medications including topical agents (lidocaine, compounded creams), tylenol, anti-inflammatories, and medications for nerve pain (gabapentin, pregabalin, nortriptyline).
  • Nerve blocks
  • Radiofrequency ablation
  • Peripheral nerve stimulation
