The study will identify if there is a difference of quality of life after surgery between two techniques used in surgery. The two different techniques are either the Single Row Fixation or the Double Row Fixation.

Condition Intervention
Rotator Cuff Tear
Procedure: single row
Procedure: double row fixation

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Single Row Versus Double Row Fixation in Arthroscopic Cuff Repair; a Randomized Controlled Sutdy.

Primary Outcome Measures:
  • Do patients who undergo a repair of the rotator cuff with arthroscopic technique using double row fixation have increased disease specific quality of life then patients who undergo a repair with arthroscopic technique using single-row fixation. [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 80

Study Completion Date: July 2011

Arms Assigned Interventions
Active Comparator: single row fixation Procedure: single row
This method involves using a single row of anchor(s) to reattach the cuff to the bone.
Other Name: non applicable
Active Comparator: double row fixation Procedure: double row fixation
This technique, "double row" fixation, involves adding an extra anchor(s) over the number used for single row fixation. This extra anchor(s) is placed further inside the bone and may help to increase the fixation strength of the repair.
Other Name: non applicable

Detailed Description:
Primary Research Question; What is the difference in disease specific quality of life between patients who undergo a repair of the rotator cuff with arthroscopic technique using single-row fixation, versus double-row fixation, as measured by the Western Ontario Rotator Cuff Index (WORC)at one year post op?

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Patients who have failed standard non-surgical management of their rotator cuff tear, and who would benefit from a surgical repair of the cuff.
  • Imaging and intra-operative findings confirming a full thickness tear of the rotator cuff.

Exclusion Criteria:

  • Characteristics of the cuff tear that render the cuff irrepairable.
  • Significant shoulder comorbidities
  • Previous surgery on affected shoulder
  • Patients with active workers compensation claims
  • Active joint or systemic infection
  • Significant muscle paralysis
  • Rotatorcuff tear arthropathy
  • Charcots arthropathy
  • Major medical illness
  • Unable to speak or read English
  • Psychiatric illness that precludes informed consent
