Arthroscopic treatment of the atraumatic shoulder instability: a case series with two-year follow-up evaluation

Abstract

SummaryBackground: The purpose of this work is to evaluate the results of arthroscopic capsulolabroplasty in patients affected by atraumatic shoulder instability (ASI). Methods: A retrospective review was performed of 10 patients (7 women and 3 men) who underwent arthroscopic treatment of symptomatic ASI. Mean age at evaluation was 27.9 (19-35) years and the mean follow-up was 23.3 (12-37) months. We evaluated recurrence rate, range of movement, apprehension and relocation tests, hyperlaxity, and sport activity. The ASES score, the Rowe score, the Simple Shoulder Test (SST) and Visual Analogue Scale (VAS) were also used as outcomes measure. Results: None of the patients experienced episodes of dislocation or subluxation after surgery. The apprehension and relocation tests produced positive results in 2 patients. Six out of 10 patients reported apprehension with the arm in specific positions. The ASES mean score was 93.4 (55-100); the Rowe mean score was 85.5 (70-100); the SST mean score was 9.1 (5.8-10). On average, external rotation is reduced by 10° in adduction, and by 8° in abduction in 6 out of 10 patients; internal rotation is reduced on average by 6.6° in abduction with the arm abducted, and was overall limited in 6 out of 10 patients. Conclusions

Comparison of clinical and patient-reported outcomes of three procedures for recurrent anterior shoulder instability: arthroscopic Bankart repair, capsular shift, and open Latarjet

“…Besides, it was also controversial that the loss of range of motion (ROM) after arthroscopic Bankart repair was minor to that after open capsular repair [17]. Some meta-analysis studies reported that Bankart repair can provide better recovery of ER at 90° abduction [18].…”

“…One interesting thing we found was that most Chinese patients, especially older patients, were more willing to use complimentary care modalities or Bankart repair due to rapid recovery. Actually, according to years of work experience, capsular shift can be a good alternative if facing anteroinferior or multidirectional type of shoulder, but not including severe bone defect [17, 26]. As for the limitation of the thesis, further study was still demanded in this field.…”
