Goal: Comparison of the effects of genicular nerve block with usg and physical therapy on pain, physical function for patients with knee osteoarthritis.
Material and Methods:102 patients with osteoarthritis of the knee with Kellgren-Lawrence (K-L) class 2 or 3 were included in the study.Patients were randomized to two groups, first being injected a total of 6 mL of lidocaine plus 40 mg of triamcinolone (TA) at 3 separate target sites: the superior lateral, superior medial, and inferior medial genicular nerves with exercise treatment and second being ten sessions of hotpack as a surface warmer, TENS as a analgezic current, ultrasound therapy as a deep warmer with exercise treatment.For the first group, the ultrasound we used: 12 MHz linear transducer. (Logic E9-GE, USA).The transducer was first placed parallel to the long bone shaft and moved up or down to identify the epicondyle of the long bone. The genicular arteries were identified near the periosteal areas, which are the junctions of the epicondyle and the shafts of the femur and tibia, and confirmed by color Doppler ultrasound.Accordingly, GNB target points should be next to each genicular artery because the superior lateral, superior medial, and inferior medial genicular artery traveled along each genicular nerve. , Visual Analogue Scale for pain(VAS) was primer outcome measurement, Western Ontorio and McMaster Universities Osteoarthritis Index (WOMAC) and six minute walk tests were seconder outcome measurements of the study applied before, after (two weeks) and 12th weeks of treatment. Primer endpoint of the study is decrease at least 40% in VAS values at 2nd week, second endpoint is the improvement in the womac and 6-minute walk test observed in the 2nd week continues until the 12th week.

| Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score | WOMAC is a scale to assess disease-related functional status and disability. It consists of three parts with 24 simple questions in total. Five questions are related to pain (WOMAC-A), two questions to morning stiffness (WOMAC-B), and the remaining 17 questions to physical condition (WOMAC-C). Each question is scored using 4-point Likert scale (0= None, 1= Mild, 2= Moderate, 3= Severe, 4= Very severe). Higher scores indicate severe pain, increased stiffness, and functional failure. Minimum score of the scale is 0 and maximum is 100. Higher scores mean worse outcomes. |

| Pre-intervention, Change from baseline WOMAC score at 12th weeks |
| Six minute walk test | It is an objective method to evaluate exercise tolerance. It was performed on an unobstructed bare 30 meters (m) floor where every 3 meters were marked. The patients were allowed to complete the test by reducing their walking speed or stopping and getting some rest, if needed. Maximum walking distance (meters) within six min was measured. Higher distance means better outcome. | Pre-intervention, Change from baseline six minute walk test at 12th weeks |
