Purpose
To determine whether curettage of the cartilage on the glenoid edge in arthroscopic
Bankart repair, reduces the postoperative recurrence rate as compared to the non-curetted
glenoid.
Methods
Between January 2010 and December 2013, 134 patients underwent arthroscopy and stabilization
for recurrent anterior dislocation of shoulder. Total 42 patients were excluded. Alternate
glenoid edge was curetted in ninety-two patients undergoing arthroscopic Bankart repair.
Twelve patients were lost to follow-up. Thereby we had 80 patients which were divided
in two groups, curettage & non-curettage, of 40 patients each. In both groups, the
Bankart lesion was repaired using minimum 3 bioanchors loaded with non-absorbable
braided sutures. Postoperative rehabilitation was the same for the 2 groups. We recorded
recurrence of instability, pain, Constant and Rowe shoulder scores. Statistical analysis
of data was performed using an unpaired t test (significance for P <0.05).
Results
Both the groups were comparable in terms of age, number of dislocations and bone loss.
The average follow-up was 7 years 9 months (range 6-10 years). Out of total 40 patients
in the curettage group, 6(15%) patients had recurrence of dislocation and none had
subluxations, whereas in the non-curettage group 13(32.5%) patients had recurrence
of dislocation and 3(7.5%) had subluxations. The difference in postoperative recurrence
of instability was statistically significant (p = 0.012). Average Rowe score in curettage
group was 83.75(SD±23.28) and 70.13(SD±31.29) in non-curettage group, the p value
being statistically significant(0.030).
Conclusions
During arthroscopic Bankart repair, curettage of the cartilage on anterior glenoid
edge reduces the incidence of postoperative recurrence of instability.
