Primary Outcome Measures:
  • to assess quality of life post-operatively of each surgical group [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Enrollment: 87
Study Start Date: November 2006
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: tenotomy 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
Active Comparator: osteotomy 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

Detailed Description:

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 ?
