      <i_freetext>Intervention 1: Intervention group: Injection of dexmedetomidine 1 microgram per kilogram + 2 ml lidocaine 2%, which is performed under ultrasound guidance with a 27-gauge needle inside the knee joint. The injection is done in one session. Intervention 2: Control group: Injection of one milliliter (40 mg) of triamcinolone + 2 ml of lidocaine 2%. The injection method is similar to the intervention group.</i_freetext>
