Comparison of the Effect of Genicular Nerve Block and Physical Therapy in Patients With Knee Osteoarthritis

6 ml of solution consisting of 5 ml 2% lidocaine hydrochloride and 1 ml 40 mg triamcinolone acetonide will be injected equally into the superomedial, inferomedial and superolateral genicular nerve branches using a 23G (0.6\*60mm) needle under ultrasound guidance.

Group 2: PT (PHYSICAL THERAPY) group: In the PT group, all interventions will be performed with the patient supine and knees in extension. First, superficial heating will be applied using a hotpack for 20 minutes, followed by therapeutic ultrasound in continuous mode at a frequency of 1 MHz and 1.5 Watt/cm2 for 5 minutes to achieve deep thermal effects. Then traditional transcutaneous electrical nerve stimulation (TENS) will be applied for 15 minutes for a total of 15 sessions.

Group 3: Control group: For 3 weeks, exercise therapy will be applied by the patient. Knee range of motion exercises, quadriceps strengthening exercises, hamstring stretching exercises will be taught to the patients by the doctor and they will be asked to do them every day, 2 times a day, 10 repetitions for a total of 3 weeks. The use of NSAIDs will be restricted during the treatment period.
