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 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.”

Inhibition of Chondrocyte and Synovial Cell Death After Exposure to Commonly Used Anesthetics: Chondrocyte Apoptosis After Anesthetics

An intra-articular injection of local anesthetics is a common procedure for diagnostic and therapeutic purposes. It has been shown that these agents are toxic to articular cartilage and synovial tissue in a dose- and time-dependent fashion, and in some cases, they may lead to postarthroscopic glenohumeral chondrolysis (PAGCL). However, the role of apoptosis in cell death is still unclear, and the potential role of apoptosis inhibition in minimizing chondrocyte and synovial cell death has not been reported.

Total shoulder arthroplasty with an uncemented soft-metal-backed glenoid component

Loosening associated with cemented polyethylene glenoid components is a major concern following total shoulder arthroplasty (TSA). The purpose of this study was to investigate the clinical and radiographic results associated with use of a novel uncemented soft-metal-backed glenoid component (SMBG), with a minimum follow-up of 2 years.
