We present three patients with persistent postoperative pain (PPP); after joint surgery they were treated successfully by ultrasound-guided pulsed radiofrequency (PRF) on the peripheral nerve. Case 1: A 56-year-old female presented with shoulder pain and a decrease in range of motion (ROM) of the shoulder after rotator cuff repair. Although she had previously undergone conventional therapies, her pain has remained for 21 months. We applied PRF to the suprascapular nerve with ultrasound guidance. After the procedure, the restricted ROM improved immediately and the pain reduced gradually. Case 2: A 79-year-old female had been experiencing refractory knee pain after total knee arthroplasty (TKA) for 9 years. We applied PRF to the saphenous nerve with ultrasound guidance. Her pain improved immediately after PRF. Case 3: A 73-year-old female with allodynia after TKA for 5 years. We performed ultrasound-guided PRF to the saphenous nerve. The allodynia improved immediately after PRF, and these effects lasted for 6 months.
