Outcome of arthroscopic radiofrequency denervation of the patella in the management of resistant patellofemoral pain syndrome

Background Patellofemoral pain syndrome is common in females as well as young active adults. The aim of the current study was to assess the outcome of arthroscopic radiofrequency denervation of the patella in patients with resistant patellofemoral pain syndrome. Patients and methods Thirty-two patients with patellofemoral pain syndrome were included, after failure of conservative treatment for at least 6 months. Exclusion criteria included lower limb malalignment, patellofemoral instability, or associated meniscal or knee ligamentous injuries. Arthroscopic patellar denervation was performed using a radiofrequency ablation device. Results The average duration of follow-up was 36.8 months (range, 24–48 months). At the final follow-up, the postoperative pain visual analog score improved from 7.4 (range, 5–9) preoperatively to 2.3 (range, 1–4). The postoperative Lysholm score improved significantly from 63.5 (range, 56–71) to 90.5 (range, 86–95) (P<0.0001), while the Kujala score improved significantly from 70.75 (range, 62–81) to 88.5 (range, 81–96) (P<0.0001). Conclusion Arthroscopic patellar denervation is a simple procedure that yields good results and no complications in the management of resistant patellofemoral pain syndrome.
