Treating the Whole Person, Not Just the Shoulder

Our focus is on helping each person overcome a condition that has altered his or her quality of life. Our approach to managing patient care includes:

  • Thoroughly evaluating each patient and his or her symptoms
  • Determining the patient's normal shoulder function
  • Diagnosing the patient's condition
  • Discussing the expected outcome
  • Developing a comprehensive care plan tailored to the patient's needs
  • Carefully considering the impact of the shoulder problem and its treatment on the patient’s overall health and expectations for recovery

Making an appointment is easy. Patients seeking initial consultations usually see one of our specialists within two weeks. If your condition is acute, you may be admitted to the hospital and scheduled to begin therapy or have surgery the following day.

Follow-up visits are scheduled to manage the patient's recovery. We also enter treatment information into our patient database, which allows us to analyze outcomes and gives patients and referring physicians complete and up-to-date information about their care. Our goal is to help all of our patients resume healthy and productive lives.

A Recognized Leader in Research & Academic Medicine

Our world-class shoulder specialists also are leaders in clinical and basic science research. By relentlessly pursuing innovation, we can offer novel techniques and advanced therapies that improve patient care.

Together with the Shoulder Biomotion Laboratory, our surgeons have developed three-dimensional imaging that compares the anatomy and function of repaired shoulders with normally functioning shoulders. This advancement has led to new treatments that more closely replicate normally functioning shoulders, often providing patients with better long-term results.

The Shoulder Service's research focuses on improving conventional techniques for shoulder replacements, rotator cuff repairs, shoulder dislocations and other disorders. One of the most promising breakthroughs our research team has helped to develop is a reverse prosthesis. This novel device is used to treat patients lacking intact rotator cuffs or with bones and tendons damaged during previous surgeries, conditions that once were considered difficult to treat.

Our international reputation as a leading academic medical center also benefits our patients. Working closely with our physicians, our talented postgraduate fellows are highly qualified, board-certified surgeons who evaluate and diagnose patients and assist our shoulder specialists during surgery.

We offer today’s most comprehensive, leading-edge therapies for the complete range of shoulder conditions, including:


All of our patient services and resources are available at the hospital’s main campus, including:

  • One-on-one evaluation, treatment and follow-up care from our shoulder specialists
  • State-of-the-art facilities for open surgical procedures (e.g. joint reconstructions and shoulder replacements)
  • Outpatient services for arthroscopic surgeries and other minimally invasive and noninvasive procedures
  • An expert team of physical therapists specializing in shoulder rehabilitation

Total Shoulder Replacement by Dr. JP Warner

Patients with severe shoulder arthritis are unable to move their arms through the full range of motion and consequently are unable to perform many activities of daily living. For these patients, total shoulder replacement is a proven surgical procedure relieving their pain, recovering their range of motion and allowing them to return to their active lifestyles. In this video, Dr JP Warner goes through the necessary examination and the surgical technique. He also points out that in 98% of the patients this is a very successful, proven procedure.
