Large Hill-Sachs Lesion: a Comparative Study of Patients Treated with Arthroscopic Bankart Repair with or without Remplissage.

ABSTRACT:

Background

There is little comparative long-term clinical data comparing Bankart repair alone to the addition of remplissage.

Questions/purposes

Our purpose was to compare results of patients with significant humeral head lesions and who underwent either isolated arthroscopic Bankart repair or remplissage.

Methods

This is a retrospective cohort study of 14 isolated arthroscopic Bankart and 10 remplissage repairs all with large engaging Hill-Sachs (HS) lesions. Average follow-up was 40.72 months (26.3-51.1) in the Bankart group and 31.55 months (24.1-39.9) in the remplissage group. Surgical failure was defined as a dislocation or subluxation. Groups were matched on handedness, age within 3 years, and HS lesion size. Glenoid bone loss and HS size were measured on MRI. Additionally, WOSI and DASH scores were obtained.

Results

The average age at surgery was 26.0 years (17.8-41.1) of the isolated Bankart patient and 24.4 years (16.4-38.3) in the remplissage group. The average HS lesion volume was 310.22 mm(3) in the Bankart group and 283.79 mm(3) in the remplissage group. The failure rate for the Bankart group was 8 out of 14 patients (57.14%). For the remplissage group, the failure rate was 2 out of 10 patients (20.0%). Average WOSI scores were 73.72 in the Bankart group and 79.54 in the remplissage group. For DASH scores, the average Disability/Symptoms Scores were 16.23 for the Bankart group and 12.05 for the remplissage patients.

Conclusions

In comparison to isolated Bankart repair, remplissage was a superior option for recurrent instability patients with large Hill-Sachs lesions as seen by diminished failure rates and improved outcome scores.
