Abstract
Purpose
To determine whether curettage of the cartilage on the glenoid edge in arthroscopic
Bankart repair reduces the postoperative recurrence rate compared with noncuretted
glenoid.
Methods
Between January 2010 and December 2013, 134 patients underwent arthroscopy and stabilization
for recurrent anterior dislocation of shoulder; 42 patients were excluded. Alternate
glenoid edge was curetted in 92 patients undergoing arthroscopic Bankart repair. Twelve
patients were lost to follow-up. The remaining 80 patients were divided into 2 groups
of 40 patients each, curettage and noncurettage. In both groups, the Bankart lesion
was repaired using ≥3 bioanchors loaded with nonabsorbable braided sutures. Postoperative
rehabilitation was the same for the 2 groups. We recorded recurrence of instability,
pain, and Constant and Rowe shoulder scores. Statistical analysis of data was performed
using unpaired t test (significance level P < .05).
Results
The 2 groups were comparable in terms of age, number of dislocations, and bone loss.
The average follow-up was 7 years and 9 months (range 6 to 10 years). Of the total
40 patients in the curettage group, 6 (15%) had recurrence of dislocation and none
had subluxations, whereas in the noncurettage group, 13 (32.5%) had recurrence of
dislocation and 3 (7.5%) had subluxations. The difference in postoperative recurrence
of instability was statistically significant (P = .012). The average (standard deviation) Rowe score was 83.75 (23.28) in the curettage
group and 70.13 (31.29) in the noncurettage group (P = .030).
Conclusions
During arthroscopic Bankart repair, curettage of the cartilage on the anterior glenoid
edge reduces the incidence of postoperative recurrence of instability.
Level of Evidence
