Arthritis is the main cause of knee pain among adults over 50 years old. Prosthetic surgery is the ultimate treatment, however percutaneous interventional pain management is a good alternative treatment for patients who are not eligible for an operation or for those who experiment persistent pain after surgery. Intra-articular corticosteroids or hyaluronic acid injections have a mild effect which is limited in time. Nerve ablation treatment using radiofrequency or cryotherapy may have longer lasting analgesic effects superior than 6 months. Finally, regenerative medicine, meaning platelet-rich plasma or mesenchymal stem cells, seems a very promising treatment by improving pain and mobility for a longer period.
