A prospective, comparative, radiological, and clinical study of the influence of the "remplissage" procedure on shoulder range of motion after stabilization by arthroscopic Bankart repair.

BACKGROUND: Certain failures of arthroscopic Bankart repairs seem to be related to the presence of a Hill-Sachs defect. It has been suggested that Hill-Sachs lesions can be treated by "remplissage" (filling in) of the defect. The effect of this procedure on the mobility of the shoulder is not known.

PURPOSE: To determine if filling in the Hill-Sachs defect with rotator cuff tendon would modify the range of motion of the operated shoulder.

STUDY DESIGN: Cohort study; Level of evidence, 2.

METHODS: A prospective study of 2 patient populations (arthroscopic Bankart repair alone vs Bankart and remplissage) was undertaken after selecting patients using the Instability Severity Index Score (ISIS). Patients with a Hill-Sachs lesion seen on anteroposterior radiographs had a remplissage procedure if this procedure allowed them to obtain an ISIS lower than 4. The main clinical outcome was the range of motion (external rotation at the side [ER1], external rotation in abduction [ER2], internal rotation [IR], and forward elevation), assessed by the difference between each shoulder at 1 and 2 years' follow-up. Complications, recurrence, and the Walch-Duplay scores were noted at the same time. Minimum follow-up was 2 years.

RESULTS: No significant statistical difference was noted in the range of motion between each group: ER1, difference of 4° (P = .22); ER2, difference of 3° (P = .49); anterior elevation, difference of 5° (P = .35); and internal rotation, 2 vertebrae (P = .22). The rate of recurrence was identical in both groups (6.25%). For patients without redislocation, the Walch-Duplay score was excellent (14/17) or good (3/17) in the first group and excellent (12/15) or good (3/15) in the second group. Posterosuperior pain during forceful movements or when tired was noted in one third of patients having undergone remplissage.

CONCLUSION: The remplissage technique did not alter the range of motion of the shoulder compared with Bankart procedure alone; however, one third of patients did experience posterosuperior pain.
