Comparing Two Surgical Methods of Fixation of Subscapularis During Shoulder Arthroplasty

This pilot study is being conducted to compare 2 methods of access to the shoulder for arthroplasty in patients with Osteoarthritis as we do not know has a better outcome.

The study investigates the difference in disease specific quality of life between patients who undergo a subscapularis tenotomy versus morselized osteotomy of the lesser tuberosity, as measured by the Western Ontario Osteoarthritis of the Shoulder (WOOS) at one year post-operatively in patients who undergo shoulder arthroplasty ?

• Tenotomy
• Morselized Osteotomy

• Procedure: tenotomy
  This treatment group will undergo a technique that involves division of the tendon to gain access to the shoulder.
  Other Name: non applicable
• Procedure: osteotomy
  This group will use a technique that involves elevation of the tendon with a wafer of bone in order to gain access to the shoulder.
  Other Name: non applicable

• Active Comparator: tenotomy
  Intervention: Procedure: tenotomy
• Active Comparator: osteotomy
  Intervention: Procedure: osteotomy
