Arthroscopic versus Open Shoulder Stabilization for Recurrent Anterior Instability

Abstract

Clinical outcomes after arthroscopic and open stabilization were comparable. Preoperative magnetic resonance arthrograms in shoulders with anterior instability allow an accurate diagnosis of intra-articular abnormality that correlates well with operative findings. Arthroscopic stabilization for recurrent anterior shoulder instability can be performed safely; the clinical outcomes are comparable to those after traditional open stabilization.

Anterior shoulder instability: a review of pathoanatomy, diagnosis and treatment

“…A meta-analysis of 501 patients treated surgically for anterior shoulder instability using suture anchors (234 arthroscopic and 267 open) found similar rates of recurrent instability (6% versus 6.7%) and need for re-operation (4.7% and 6.6%) [49•]. Subjective evaluations show no significant difference between the two treatment methods, although loss of range of motion (notably external rotation) may be increased with open repairs [50][51][52]. Some have shown that patients treated with open techniques have a lower rate of recurrent shoulder dislocations or instability than those treated with arthroscopic techniques, with the caveat that almost half of those treated with open techniques had loss of external rotation (range 10-40°loss) [53].…”

Arthroscopic Repair versus Non-operative Treatment of First-time Traumatic Anterior Shoulder Dislocations: A Numbers-needed-to-treat Analysis for Prevention of Recurrent Dislocations

“…Open surgical techniques are also currently being used in treatment of first-time traumatic anterior shoulder dislocations. Many studies [29][30][31][32] have compared open surgical procedures with arthroscopic procedures for treatment of the same population as this review. However, these studies yielded different results.…”

“…A recent systematic review 29) pooled 19 studies, and concluded that arthroscopic surgery was associated with significantly higher risk of recurrent instability compared to the open surgical procedure. Two studies 30,32) were prospective RCTs. One of them 30) demonstrated that both techniques yielded similar postoperative results, but recommended arthroscopic procedure because it can be performed safely.…”

“…Two studies 30,32) were prospective RCTs. One of them 30) demonstrated that both techniques yielded similar postoperative results, but recommended arthroscopic procedure because it can be performed safely. Another study 32) reported that no significance was found, but the authors mentioned that open is a more reliable method for collision athletes.…”
