    And Complex


Dr. Ratnayake is a fellowship trained Orthopaedic Spinal Surgeon in Sacramento, California specializing in the comprehensive care of patients with complex spinal disease. He specializes in all regions and aspects of spinal care including disorders of the cervical, thoracic, and lumbar spine. He has extensive fellowship training in advanced minimally invasive and complex spinal surgery techniques.

Care Philosophy

Dr. Ratnayake believes that every patient should have a comprehensive understanding of their condition and what options are available to them so they can make meaningful and well-informed decisions about their care. As a core value, he believes surgery should always be tailored to each individual after non-operative management has failed and that every patient should be treated as though they are his family. If surgery for the spine can be of benefit, his goal is to provide the most minimally invasive approach that will also lead to the most durable outcome in the safest possible way.

Patient Stories

Dr. Ratnayake is amazing! I had been suffering from a herniated disc for a year and nothing was working to manage the pain. I was scared of getting surgery, but after speaking to him my fears went away. He took his time educating me about my condition, answering all of my questions, and explaining the whole procedure. He even offered to discuss other treatment options. It really felt like he listened to all of my concerns. He made me feel like I was in charge of my own health. Next to finally finding relief from constant nerve pain, receiving care from Dr. Ratnayake was probably the best thing to happen to me in 2020. I would highly recommend him and his practice.

I highly recommend Dr. Ratnayake. He performed my herniated disc surgery and I only have good things to say. He is very clear at explaining things, friendly, responsive, and professional.

-- Hagop

Dr. Ratnayake is very good doctor. He listened to me explain my lower back pain, reviewed my x-rays and then explained to me in very simple terms what my back issues were and what options I had in treating those symptoms. I elected to have surgery and could not be happier. My pain is gone. Dr. Ratnayake's follow up after surgery was also very good. He really cares about the well-being of his patients. If you have any back issues I highly recommend you see Dr. Ratnayake.

-- J. Murk

Dr. Ratnayake took great care of me. His communications are professional, warm, and caring. He addressed my questions patiently, clearly, and enthusiastically. In terms of his skills, I had seriously debilitating symptoms before surgery, and none afterwards. My recovery has been smooth. I'm walking miles pain free! I wholeheartedly recommend Dr. R.
