Purpose
The objective of this study was to compare the functional assessments of arthroscopy
and open repair for treating Bankart lesion in traumatic anterior shoulder instability.
Methods
Fifty adult patients, aged less than 40 years, with traumatic anterior shoulder instability
and the presence of an isolated Bankart lesion confirmed by diagnostic arthroscopy
were included in the study. They were randomly assigned to receive open or arthroscopic
treatment of an isolated Bankart lesion. In all cases of both groups, the lesion was
repaired with metallic suture anchors. The primary outcomes included the Disabilities
of the Arm, Shoulder and Hand (DASH) questionnaire.
Results
After a mean follow-up period of 37.5 months, 42 patients were evaluated. On the DASH
scale, there was a statistically significant difference favorable to the patients
treated with the arthroscopic technique, but without clinical relevance. There was
no difference in the assessments by University of California, Los Angeles and Rowe
scales. There was no statistically significant difference regarding complications
and failures, as well as range of motion, for the 2 techniques.
Conclusions
On the basis of this study, the open and arthroscopic techniques were effective in
the treatment of traumatic anterior shoulder instability. The arthroscopic technique
showed a lower index of functional limitation of the upper limb, as assessed by the
DASH questionnaire; this, however, was not clinically relevant.
Level of Evidence
Level II, randomized controlled trial.
