Approach to treating patients

EL DORADO ORTHOPAEDICS is the association of 3 prominent surgeons in Folsom, CA. Each fills a specific niche in the care of orthopedic and sports conditions. All doctors are currently accepting new patients, and our appointment waiting period to see a doctor is typically about 3 working days! Your primary doctor can also request same-day evaluations with a simple phone call!

Dr. CEDRIC L. WONG is a Board-Certified general orthopedic surgeon with special interest in sports injuries. He takes care of most orthopedic conditions in patients of all ages. His prior duties in the US Air Force give him extensive experience in the care of sports injuries, including "anatomic" ACL reconstruction, arthroscopic surgery, and fracture care, but he cares for nearly all non-spine orthopaedic conditions, including hand conditions like carpal tunnel syndrome, and joint replacement surgery for severe arthritis. He also performs "tip of the spear" procedures like PRP injections, MAKOplasty knee and hip procedures, subchondroplasty, KneeAlign navigation for total knee replacement surgery, and rotator cuff reconstruction with Dr. Sfakianos.

Dr. PETER SFAKIANOS is a Board-Certified Orthopaedic Surgeon who concentrates on knee and shoulder conditions. He practiced in the Sacramento and Jackson areas for over a decade prior to settling in Folsom. He has a strong interest in difficult and failed rotator cuff tears and has developed a cutting-edge procedure for pain relief, improvement of function, and delay in progression into arthritis.

Dr. ROBERT SLATER is Board-Certified in Orthopaedic Surgery with Certificate of Added Qualification (CAQ) in surgery of the hand and upper extremity. He has lived and worked in the Sacramento region since 1995. His practice is devoted to disorders of the upper extremity including abnormalities of the shoulder, elbow and hand such as arthritis, fractures, damaged tendons and nerve injuries, carpal tunnel syndrome, and work-related injuries to name a few.

The doctors see all their own patients, in contrast to other practices where you might see a "physician extender". We deliver prompt evaluation and complete treatments plans. Patient input is encouraged and requested. Non-operative options are explored before considering surgery in all cases.

Our care extends to patients east and west along the Highway 50 corridor, south to Rancho Murieta and Jackson, and north to Auburn, Roseville and Lincoln.

Please call 916-984-4500 to arrange your appointment. Request us by name and have your Primary Care Provider fax your referral to us at 916-984-4502. We look forward to helping you!
