Description
The unicortical button fixation showed a significantly lower gap of failure, higher failure load and number of cycles until failure, and higher load to reach 1-mm, 5-mm, and 10-mm gap compared with the traditional TO repair for SSc. However, we could not find the major difference in footprint area between two groups.
The unicortical button fixation provided an alternative technique for subscapularis repair following total shoulder arthroplasty with superior biomechanical profiles. Additional work is necessary to validate this outcome clinically.
