There are many options that can improve your pain & delay the need for knee surgery. Try contacting a pain management specialist, not just an orthopedic surgeon. In the past 10 yrs, I've had cortisone shots, Hyaluronic gel injections, nerve blocks, RFA- Radio Frequency Ablation (they burn out the nerves that send pain messages to the brain) multiple rounds of physical therapy & many types of medication, including opioids. Each treatment has pros & cons, be sure & research them thoroughly & discuss options for your specific needs. None of them will be a miracle cure but can improve your symptoms. Good luck!
