Bottom Line: Those who were dissatisfied or suffered recurrent symptoms had statistically significant lower constant scores at the final follow up.Our success rate was comparable to similar arthroscopic techniques and results published in the literature.There was very little reduction in range of movement following surgery and the rhythm of shoulder motion, particularly external rotation in abduction was improved.

ABSTRACT

Purpose: Traumatic anterior dislocation of the shoulder is a common occurrence increasingly being treated arthroscopically. This study aims to determine the outcome of arthroscopic anterior stabilization using bioknotless anchors and analyze the motion in a subset of these patients.

Materials and methods: The outcome of 20 patients who underwent arthroscopic anterior stabilization using the bioknotless system was studied (average follow-up 26 months). Four of these patients underwent motion analysis of their shoulder pre- and post-operatively.

Results: 15% were dissatisfied following surgery and the recurrence of instability was also 15%. Those who were dissatisfied or suffered recurrent symptoms had statistically significant lower constant scores at the final follow up. Pre-operative motion analysis showed a disordered rhythm of shoulder rotation which was corrected following surgery with minimal loss of range of motion.

Conclusions: Our success rate was comparable to similar arthroscopic techniques and results published in the literature. Patient satisfaction depended more on return to usual activities than recurrence of symptoms. There was very little reduction in range of movement following surgery and the rhythm of shoulder motion, particularly external rotation in abduction was improved.

Level of evidence: Four retrospective series.

Mentions: Traumatic anterior dislocation of the shoulder is a very common condition, with an approximate incidence of 10-20 per 100,000 per year.[1] Following the initial event there is a high risk of recurrence, estimates between 20% and 90% have been reported in the literature[2–5] with approximately 17% occurring in the first week and the remainder up to 7 years later.[6] Arthroscopic anterior stabilization is a well recognized and increasingly popular technique with level 1 evidence to support its use in this condition.[7] A variety of labral fixation devices have been described. We present our experience using the bioknotless anchor (DePuy Mitek, Raynham, MA) [Figure 1] and use the fastrack motion analysis system (Polhemus, Colchester, VT) in a small cohort of these patients to assess pre- and post-operative shoulder kinematics.
