N=104 juvenile idiopathic arthritis patients diagnosed after ILAR criteria with unilateral persistent knee arthritis. They will be randomly assigned into two groups; group 1 will receive genicular nerve block, group 2 intra-articular triamcinolone. Both groups will be examined by SOLAR ultrasound scoring system, Visual analogue scale and Lysholm score at 0, 2 and 12 weeks. A semi-quantitative score will be used to assess tenderness and swelling at the same intervals.
