Rotator Cuff Sparing Total Shoulder Replacement

Full Title of Study

Rotator Cuff sparing total shoulder arthroplasty--A prospective, randomized clinical trial (R#10-02125)

Purpose of Study

To collect and evaluate long-term clinical data on patients whose total shoulder replacement (TSR) is performed using the traditional surgical approach (called the subscapularis release approach) as compared to patients who have a TSR procedure done using a new surgical approach (called the rotator cuff sparing approach). After surgery, doctors will examine motion, strength, and functional use of the shoulder. In addition, they will specifically test the rotator cuff strength after the surgery. In this fashion, they plan to test the hypothesis that rotator cuff sparing TSR can improve the rotator cuff function while maintaining the excellent pain relief and motion that is normally observed after the traditional TSR procedure. 

Basic Inclusion Criteria (requirements for being included in study)

Basic Exclusion Criteria (reasons for being excluded from study)

  • Prior total shoulder replacement in the affected shoulder
  • Significant deformity or injury of the shoulder that requires a custom made implant

Study Visit Requirements

Patients are evaluated preoperatively and will complete a questionnaire on their pain, disability, and quality of life at the time of surgery and postoperatively weekly at approximately 6 weeks, 3 months, 6 months, 12 months, and annually thereafter.
