Introduction and purpose
Antirotation sling: adduction and endorotation
increased tension SST/IST
Abduction brace: abduction and neutral rotation
less tension SST/IST
Hypothesis: there will be less tension on the repaired tendons and thereby less pain with the abduction brace compared to the antirotation sling.

Conclusion
• On the short term the level of pain, QOL and function was not significantly different between groups.
• No retears were observed.
• Study results might be significantly different when completed.
