Minimally Invasive Treatment

Arthroscopic surgery is a minimally invasive technique that uses small incisions and a tiny camera/video to treat many injuries of the shoulder. Many sports injuries result in a labral tear or rotator cuff tendon tear which are effectively treated arthroscopically today. Some salvage procedures for irreparable rotator cuff tears such as superior capsular reconstruction or subacromial balloon placement can also be performed arthroscopically today. Dr. Costouros has treated elite athletes at all levels, from the recreational athlete to collegiate, olympic, and professional athletes.

Rapid Recovery

Arthroscopic surgeries are done on an outpatient basis and generally take less than 1-hour to complete. Patients experience less pain and scarring following surgery, return home on the day of surgery, and are able to recover and resume their normal activities much more quickly.

Comprehensive Care

As a specialist in all aspects of shoulder disorders, this will be your last stop in treatment. Dr. Costouros will help you obtain a pain-free and fully-functional shoulder so that you can remain active and live your life to the fullest.


Dr. John G. Costouros MD, FACS, FAAOS

Shoulder Disorders Specialist and Shoulder Surgeon at the Institute for Joint Restoration and Research

Shoulder Disorders Specialist and Shoulder Surgeon at the Institute for Joint Restoration and Research Dr. Costouros has devoted his entire career to becoming an expert in the comprehensive treatment of all disorders affecting the shoulder — from sports injuries, to fractures, rotator cuff tears, instability problems and arthritis. As a prior full-time member of the Stanford Orthopedic Surgery Faculty, he has trained hundreds of surgeons from around the world and has shared the very latest advancements and techniques. Although many injuries of the shoulder can be treated without surgery, those that will require an operation can be treated today with arthroscopic surgery – a minimally-invasive technique that requires minimal downtime and enables faster recovery. Dr. Costouros also specializes in shoulder joint replacement surgery for more complex problems such as advanced arthritis or some irreparable rotator cuff tears. He has been a leader in developing cutting-edge technology for shoulder surgery and has led multiple FDA clinical trials which have benefitted patients throughout the country. He has partnered with Dr. John Dearborn at the Institute for Joint Restoration and Research where they share the same philosophy of providing patients “better and more consistent care in a specialty setting focused on exceptional outcomes, service and quality.”

Anatomic Total Shoulder Arthroplasty: Component Size Prediction with 3-Dimensional Pre-Operative Digital Planning

The rate, complexity, and cost of total shoulder arthroplasty (TSA) continues to grow. Technology has advanced pre-operative templating. Reducing cost of TSA has positive impact for the patient, manufacturer, and hospital. The aim of this study was to evaluate the accuracy of implant size selection based on 3-D templating. Our hypothesis was that pre-operative templating would enable accurate implant prediction within one size.

Eclipse stemless shoulder prosthesis vs. Univers II shoulder prosthesis: a multicenter, prospective randomized controlled trial

Total shoulder arthroplasty is an accepted treatment for glenohumeral osteoarthritis. The Arthrex Eclipse shoulder prosthesis is a stemless, canal-sparing humeral prosthesis with bone ingrowth capacity on the trunnion, as well as through the fenestrated hollow screw, that provides both diaphyseal and metaphyseal load sharing and fixation.
