Background: The purpose was to evaluate the
results in selected high-risk patients who
underwent arthroscopic stabilization of the
shoulders with recurrent anterior instability.
Hypothesis: Arthroscopic stabilization using
suture anchors is useful for athletes aged less
than 25 years or contact athletes without a large
bone loss of glenohumeral articulation.
Study design: Prospective cohort study.
Methods: Study group comprised 55 patients with
a mean follow-up of 42 months (range, 25 to 72
months). Thirty-two had recurrent dislocations, 14
recurrent subluxations and nine recurrent
subluxations after a single dislocation. Rowe
score, range of motion, recurrence, and sports
activities were evaluated.
Results: Mean Rowe score improved from 30.1 to
92.3 points; 45 (82%) were excellent, six (11%)
good, zero fair, and four (7%) poor. Patients had
lost a mean of 4 of external rotation in adduction.
Four (7%) had recurrence. Recurrence rate in
contact athletes (9.5%, two of 21) was not
statistically different from that in non-contact
athletes (5.9%, two of 34). Forty-four (80%)
returned at the same levels. Complete return rate
in overhead athletes (68%, 17 of 25) was lower
than that in non-overhead athletes (90%, 27 of 30)
(p=0.0423).
Conclusion: Arthroscopic stabilization is a reliable
procedure in selected high-risk patients.

Objectives: Posterior shoulder instability is a
diagnostic challenge and a poorly understood
clinical problem. Due to the complexity and
relative infrequency of diagnosis, several surgical
techniques have been described to treat this
disorder. The purposes of this study are to
evaluate arthroscopic posterior shoulder
stabilization and to evaluate multiple
preoperative and intraoperative variables as
predictors of outcome.
Materials and Methods: Thirty-four consecutive
patients who underwent posterior arthroscopic
shoulder stabilization with suture anchors and/or
suture capsulo-labral plication from October 1999
through April 2003 were reviewed. One was lost to
follow-up. All but one were male, and all but one
were active duty military. The mean age was 25.5
yrs. Nine patients had failed prior surgical
intervention. Shoulder outcomes rating scores
were determined using the American Shoulder
and Elbow Surgeons Rating Scale (ASES), the
Subjective Patient Shoulder Evaluation, and the
Single Assessment Numeric Evaluation (SANE).
Results: Mean follow-up was 28 months. Overall,
symptoms were improved, and outcomes scores
rated as good or excellent in 26 of 33 shoulders
with a mean ASES score of 97, Rowe Score of 95.5,
Subjective Shoulder Rating of 21.7, and SANE of
92. There were a total of seven failures four for
recurrent instability and three for pain. Mean
ASES score for the failures was 86, Rowe Score of
67.1, Subjective Shoulder Rating of 14, and SANE
of 72. Preoperative versus postoperative range of
motion examination demonstrated improved
values for flexion (172º vs. 165º, p>0.05) and
abduction (168º vs. 158º, p>0.05). The amount of
posterior translation averaged +3.4 (range 3+ to
4+) preoperatively versus +0.8 postoperatively
(range 0+ to 2+), p
