Sažetak
Background: Therapeutic genicular nerve block (TGNB) is both an effective and
safe treatment procedure for pain related to chronic osteoarthritis of the knee (OA). It is most common
amongst the elderly. It is characterized by joint stiffness, pain and disability.
Aim: The aim of this study was to examine the analgesic and functional impact of ultrasound-guided
TGNB in patients with chronic knee OA and to evaluate the efficacy of local anesthetics and corticosteroids.
Patients and methods: The study included 20 patients. Pain was assessed according to the numerical
pain scale (NRS), and improvement of the functional capacity was assessed according to
the WOMAC Index (Western Ontario and McMaster Universities Osteoarthritis Index). SLGN,
SMGN and IMGN were identified, and 3 mL of a mixture of local anesthetic (ropivacaine 0.75%)
and corticosteroid (triamcinolone 40 mg) were applied to each nerve.
Results: The average NRS value before TGNB was 5.1, and the WOMAC score was 58.55. After
the TGNB was performed, NRS was 2.4 (47% decrease in pain intensity) and WOMAC was 30.1
(51% decrease in the intensity of ailment).
Conclusion: TGNB is effective and not harmful in treating pain and enhances the functional
capacity in patients with knee OA. The clinical benefits of corticosteroid administration suggest that
it may be an appropriate adjuvant in TGNB for knee OA.
