The Recenter: an augmented Bankart. Results with a minimum follow-up of 2 years

Objectives: The objective was to evaluate the clinical results of a new surgical technique to improve the Bankart repair by adding a prosthetic block called the Recenter. Methods: Thirty-two patients were retrospectively included in this multicenter study. Five patients were lost to follow-up. The surgical indications were similar to those for a standard Bankart repair. A metal implant called a Recenter was inserted in the anterior inferior glenoid and fixed with two TightRopes. A Bankart repair was then performed over the implant. All the patients had a follow-up CT scan and a clinical examination. The mean follow-up period was 37 months (29-47). The mean ISIS score was 2.42 (0-6). Results: Twenty-six patients aged 33.9 ± 10.2 (16-50) years were included. Patients presented with an average of 2.4 ± 3.2 (0-12) true dislocations prior to surgery and 6.1 ± 8.5 (0-30) subluxations. The time that had elapsed between the occurrence of the first symptoms and surgery was 6.8 ± 6.9 years. The last follow-up showed a residual VAS score of 1.3. The mean Walch-Duplay score was 78.9 ± 21.4 - SD (range 5-100), the mean ROWE score, 88.5 ± 15.9 - SD (30-100) and the mean SST score, 90.6 ± 14.5 - SD (41.6-100). 77.8% of the patients (n=21) had no apprehension, 11.1% (n=3) were apprehensive, 7.4% (n=2) were afraid of the possibility of luxation and 3.7% (n=1) had a recurrence. In terms of satisfaction, 59.3% were very satisfied, 33.3% satisfied and 7.4% dissatisfied with their operation. Concerning the CT study, we found no shifting of material or ballooning of the TightRope tunnels. Conclusion: The Recenter showed a recurrence rate of 4% (1 patient) with an average follow-up of 3 years. Despite a small number of patients, the Recenter appears to be a worthwhile addition to the arthroscopic Bankart technique.
