The results of arthroscopic anterior stabilisation of the shoulder using the bioknotless anchor system

<p>Abstract</p> <p>Background</p> <p>Shoulder instability is a common condition, particularly affecting a young, active population. Open capsulolabral repair is effective in the majority of cases, however arthroscopic techniques, particularly using suture anchors, are being used with increasing success.</p> <p>Methods</p> <p>15 patients with shoulder instability were operated on by a single surgeon (VK) using BioKnotless anchors (DePuy Mitek, Raynham, MA). The average length of follow-up was 21 months (17 to 31) with none lost to follow-up. Constant scores in both arms, patient satisfaction, activity levels and recurrence of instability was recorded.</p> <p>Results</p> <p>80% of patients were satisfied with their surgery. 1 patient suffered a further dislocation and another had recurrent symptomatic instability. The average constant score returned to 84% of that measured in the opposite (unaffected) shoulder. There were no specific post-operative complications encountered.</p> <p>Conclusion</p> <p>In terms of recurrence of symptoms, our results show success rates comparable to other methods of shoulder stabilisation. This technique is safe and surgeons familiar with shoulder arthroscopy will not encounter a steep learning curve. Shoulder function at approximately 2 years post repair was good or excellent in the majority of patients and it was observed that patient satisfaction was correlated more with return to usual activities than recurrence of symptoms.</p

A new technique to improve tissue grip and contact force in arthroscopic capsulolabral repair: the MIBA stitch.

The success of anatomic repair of Bankart lesion diminishes in the presence of a capsule stretching and/or attenuation is reported in a variable percentage of patients with a chronic gleno-humeral instability. We introduce a new arthroscopic stitch, the MIBA stitch, designed with a twofold aim: to improve tissue grip to reduce the risk of soft tissue tear, particularly cutting through capsular-labral tissue, to and address capsule-labral detachment and capsular attenuation using a double loaded suture anchor. This stitch is a combination of horizontal mattress stitch passing through the capsular-labral complex in a "south-to-north" direction and an overlapping single vertical suture passing through the capsule and labrum in a "east-to-west" direction. The mattress stitch is tied before the vertical stitch in order to reinforce the simple vertical stitch, improving grip and contact force between capsular-labral tissue and glenoid bone
