Abstract accepted for poster presentation at USU Research Days 2025.

Active duty Service Members may be at increased risk for developing knee osteoarthritis  (KOA) due to the fitness demands and predisposition for traumatic joint injuries. Military and civilian  patients may benefit from alternative procedures including genicular radiofrequency ablations (RFA).

Case 1 is a 56-year-old male retiree with chronic knee pain (> 5 years) and radiographic evidence of left KOA [Kellgren-Lawrence (KL) Score: 2]. Case 2 is a  79-year-old male retiree with chronic right knee pain (1-5 years) and radiographic evidence of right KOA (KL Score: 1). Both patients received genicular RFA procedures targeting nine nerve sites: superomedial, superolateral, inferomedial, inferolateral genicular nerves, nerve to vastus medialis, medial branches of  nerve to vastus intermedius, nerve to vastus lateralis, lateral branches of nerve to vastus intermedius,  and infrapatellar branch of the saphenous nerve. Patient-reported outcome measures [i.e., Knee Injury  and Osteoarthritis Outcome Score-12 (KOOS-12), Modified 4-Item Brief Pain Inventory Scale (mBPI)] were collected at baseline and 12 weeks post-procedure.

By day 7 post-procedure, both patients reported their knee pain to be very much improved and  0/10. mBPI scores (Case 1: -4.75; Case 2: -3) and KOOS-12 subscale scores for pain (Case 1: -1; Case 2: - 6), function (Case 1: -3; Case 2: -6), and quality of life (Case 1: -1; Case 2: -3) improved in both patients at  12 weeks post-procedure.

These cases demonstrate the modified genicular RFA technique can yield symptom relief as  soon as 1-week post-procedure, with overall improvement out to 12 weeks, which is consistent with  non-randomized studies demonstrating better improvement with targeting more nerves (nine versus  traditional three). These study results may support expansion of effective conservative treatment  options for military beneficiaries with KOA.
