I am seeing Dr Ackerman in Kamloops BC. I have had 2 sets of x rays and will be getting a MRA, in other words a MRI with the dye. He seems very thorough. I feel really good under his care. However, he prefers open surgery but told me when we reach the decision making phase that if I really want arthroscopic that he will recommend me to someone. Does anyone know much about which is better? Open or arthroscopic.
