Good clinical outcomes and low recurrence rate in patients undergoing arthroscopic revision Latarjet for failed arthroscopic Bankart repair

Abstract

BackgroundThe role of arthroscopic Latarjet stabilization after failed arthroscopic Bankart repair has yet to be definitively established and merits further investigation. ObjectiveTo assess clinical and radiological outcomes after arthroscopic Latarjet stabilization as a revision procedure for failed Bankart repair, as well as the return to athletic activity and complication rates. MethodsBetween 2009 and 2020, patients with a previous failed arthroscopic Bankart repair who were treated with an arthroscopic Latarjet were retrospectively evaluated. Clinical outcomes at a minimum of 24 months postoperatively included Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome score (CS), and Single Assessment Numeric Evaluation (SANE). Dislocations, subluxations, complications, pre and postoperative level of activity and degree of osteoarthritis were also assessed. ResultsA total of 77 patients, mean age at revision surgery 31.2 ± 9.1 and with either one (n = 59), two (n = 13), or three (n = 4) arthroscopic previous stabilizations underwent revision surgery using arthroscopic Latarjet procedure were studied. Postoperatively, the mean ROWE and CS scores increased from 41.8 ± 16 to 90.7 ± 14.3 (p<0.001) and from 50.5 ± 13.8 to 90.5 ± 10.3 (p<0.001), respectively. WOSI decreased from 1247 ± 367.6 to 548.9 ± 363 at the final follow-up (p<0.001). After a mean follow-up of 39.6 ± 23.1 months, 64 shoulders (83.1%) were subjectively graded as good to excellent using SANE score. Grade 1, 2, and 3 osteoarthritis, according to Ogawa et al were found in 18 (23.4%), 6 (7.8%), and 3 (3.9%) shoulders, respectively. Six dislocations after revision surgery were reported (7.8%). In four failed cases an Eden-Hybinette procedure was conducted and in remaining two patients an arthroscopic extraarticular anterior capsular reinforcement was performed. Significantly decreased level of athletic activity was observed postoperatively (p= 0.01). ConclusionsArthroscopic Latarjet for revision of failed arthroscopic Bankart repair provides satisfactory patient-reported subjective outcomes with low rate of recurrences and complications. However, decreased level of athletic activity is expected.
