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: Patients are placed in the beach chair position under general anesthetic and interscalene brachial plexus block. Examination under anesthesia is carried out followed by a standard diagnostic arthroscopy. All patients were found to have increased anterior translation of the humeral head and one had increased posterior translation in addition. All patients were found to have a Bankart lesion, seven of whom had an additional Hill-Sachs lesion and three also had SLAP lesions. Repair of the Bankart and/or SLAP lesion was performed using the bioknotless anchors as described elsewhere.[910] For small lesions, two anchors may suffice but for larger defects, especially when a Bankart extends into a SLAP lesion, four or five anchors may be required. In our series, on an average of 2.6 anchors were used (range 2-4) [Figure 2].
