Vapocoolant Spray Application During Intraarticular Knee Injection

The goal of this observational study is to learn about the effects of vapocoolant spray applied during intraarticular knee injections on pain and anxiety compared to injections without any agent application in patients with knee osteoarthritis. The main questions it aims to answer are: • Contrary to popular belief, does coolant spray application really reduce pain? • Does it have an advantage over patients with placebo or no spray at all? After intraarticular knee hyaluronic acid application, patients will be asked to indicate injection-related pain and anxiety levels on a 100mm visual analog scale. Researchers will compare the patient groups who were applied coolant spray, placebo spray and injection without any spray.
