title: [Arthroscopic management of recurrent anterior shoulder dislocation by combining a labrum suture with antero-inferior holmium:YAG laser capsular shrinkage].
abstract: Current arthroscopic treatments do not address satisfactorily the capsular redundancy frequently associated with the Bankart lesion in recurrent anterior dislocation. Although the Bankart lesion heals, many of the recurrences after arthroscopic procedures are due to capsular redundancy and the laxity of glenohumeral ligaments. We propose that laser-assisted capsular shrinkage (LACS) be combined with arthroscopic labrum reattachment. As shown by Market et al., significant capsular shrinkage can be achieved by the application of non-ablative Ho:YAG laser energy without detrimental effects to the relaxation properties of the tissue. For 1 year we have used LACS together with labrum suture in 18 shoulders in 18 patients (mean age 24.6 years). All patients suffered from chronic anterioinferior recurrent dislocation. The labrum suture was realized by an anterior reattachment (REVO screws, Linvatec, USA) or by transglenoid suture. Two or three sutures were passed through the torn labrum with 2/0 non-absorbable suture material. The LACS procedure was performed with a holmium:YAG laser (VersaPulse, Coherent, USA) at an energy of 10 W (1 J, 10 Hz) with a 30 degrees curved handpiece. All patients were immobilized in a sling for 4 weeks postoperatively. Physical therapy was begun at 1 month with passive and active exercise. To date, none of the patients have had a recurrence. Seven of 18 patients returned to their previous sports activity, and at the same level. None of the patients had an iatrogenic lesion due to the laser application or labrum suture. Compared to the other shoulder, the loss of external rotation with the arm 90 degrees abducted was 30 degrees at 4 weeks and 10 degrees at 4 months. We think that the LACS procedure is a good treatment for the capsular redundancy that is frequently associated with Bankart's lesion in recurrent anterior dislocation and is probably responsible for the high failure rate in current arthroscopic procedures. Our results are short-term results, but we expect the capsular shrinkage associated with the labrum reattachment will provide a long-term success rate that is comparable to open procedures.
