title: Arthroscopic management of recurrent anterior dislocation of the shoulder: analysis of technical modifications on the Caspari procedure.
abstract: Arthroscopic treatment was performed on 71 patients with recurrent shoulder dislocations; all of the patients had monoplanar anterior instability attributable to arthroscopically diagnosed Bankart lesion. Of the 71 operations, 29 were performed using the original Caspari technique (follow-up, 59 months), and 42 were performed after modifications made in the original technique (follow-up, 38 months), notably improved preparation of the capsular reinsertion zone and increase in the number of monofilament points and their anchorage directly to the bone, on the spine of the scapula. We compared the results obtained in these two differently treated groups, taking into account several factors in the patient's history and clinical condition. These included the number of dislocation episodes before the operation, as well as clinical findings regarding stability, movement, function and pain (Rowe scale score), contralateral shoulder laxity, level of preoperative versus postoperative athletic activity, and postoperative recurrence rate. In the Caspari-treated group, we obtained 66% satisfactory results compared with the 90% obtained in the second group. The recurrence rate was 27% in the first group compared with 4.8% in the second group. These data were statistically significant. No correlation was found between preoperative number of dislocations and recurrence rate, nor for contralateral shoulder laxity. No significant difference was found regarding resumption of sport activity in the two groups. Our data indicate that, with accuracy in patient selection and effective surgical technique, the recurrence rate can be reduced, and results similar to those of the arthrotomic technique may be obtained.
