Postoperative functional outcome and stability in recurrent traumatic anteroinferior glenohumeral instability: comparison of two different surgical capsular reconstruction techniques
Abstract:Our results demonstrate no significant differences between the two capsular reconstruction techniques regarding patient's satisfaction, Rowe and Constant Scores. However, the anatomically orientated anteroinferior capsular shift leads to a significantly smaller external rotation deficit and seems to offer a more reliable postoperative stability.
“…The results of this study indicate that open Bankart repair and capsular shift procedures could provide good results in the treatment of traumatic recurrent anterior instability of the shoulder. These findings support and extend previous studies examining the relationship between Bankart size and the postoperative functions [3, 5–8, 16, 17], in which severity of Bankart lesion, labrum pathology, and glenoid condition were correlated to the postoperative prognosis [10]. Moreover, our findings suggested that the size of the Bankart lesion was negatively associated with surgical outcomes (Table 4), while the age at first dislocation, age at operation, and duration of instability were not associated with the surgical outcomes (Table 5).…”

“…We used the method of glenoid‐based capsular shift described by Neer and Foster [18]. Preservation of shoulder external rotation is essential if there is the demand to return to the same level of play as before the surgery [5, 12, 19, 20]. The average loss of external rotation after operation was 10°.…”

“…Suture anchors were used to facilitate the Bankart reconstruction [2][3][4]. Good results were reported to range from 91% to 97% [3][4][5][6][7][8]. However, few studies have discussed that whether the size of Bankart lesions could affect surgical results.…”
This retrospective study was to demonstrate the clinical outcome of open Bankart repair with suture anchors for recurrent anterior shoulder instability, and to compare surgical results of small (<3 clock units) and large (>3 clock units) Bankart lesions. With an average follow‐up of 55.6 months (2–8 years), there were 82 patients (60 right, 22 left shoulders) with the mean age of 27 years accepting open Bankart repair with suture anchors and capsular shift procedure by the same team. According to surgical findings, these patients were grouped into small (<3 clock units) and large (>3 clock units) Bankart lesions. Subjective outcomes were recorded according to the Bankart scoring system of Rowe. Rowe scores averaged 85.9±12.9 (range 25–100). The patients, 92–7 %, had objectively excellent or good results. Twenty nine patients (35.4%) had small Bankart lesions and 53 patients had large Bankart lesions. The Rowe scores in small Bankart lesions were better than that in large Bankart lesions (93.5±6.8 vs.81.8±13.6, Wilcoxon rank sum test, P<0.001). Mean scores of stability (Wilcoxon rank sum test, P=0.043), motion (Wilcoxon rank sum test, P=0.037), and function (Wilcoxon rank sum test, P<0.001) in small lesions also had superior outcomes than in large lesions. Four patients (4.9%) got fair results and two (2.4%) patients got poor results at the end of follow‐up. The average loss of external rotation is 10°. Open Bankart repair with the aid of suture anchors still got satisfactory results in the treatment of traumatic recurrent anterior instability of the shoulder. The size of the Bankart lesion was a factor affecting surgical outcome. Small Bankart lesions usually got better results than large Bankart lesions.

“…Rowe [33] reported in 1978 excellent and good functional results in 97% and a recurrence rate of 3.5% with this technique after an average follow-up duration of 6 years. Different studies have proven this technique as a sucessful treatment for traumatic anterior shoulder instability with recurrence rates below 10% [13,15,16,24,29,32,40]. However, long-term follow-up studies and investigations including subluxation as a failure demonstrated a higher recurrence rate than expected [26].…”
PurposeBoth open and arthroscopic Bankart repair are established procedures in the treatment of anterior shoulder instability. While the open procedure is still considered as the "golden standard" functional outcome is supposed to be better in the arthroscopic procedure. The aim of this retrospective study was to compare the functional outcome between open and arthroscopic Bankart repair.Materials and methodsIn 199 patients a Bankart procedure with suture anchors was performed, either arthroscopically in presence of an detached, but not elongated capsulolabral complex (40) or open (159). After a median time of 31 months (12 to 67 months) 174 patients were contacted and agreed to follow-up, 135 after open and 39 after arthroscopic Bankart procedure.ResultsRe-dislocations occurred in 8% after open and 15% after arthroscopic Bankart procedure. After open surgery 4 of the 11 re-dislocations occurred after a new adequate trauma and 1 of the 6 re-dislocations after arthroscopic surgery. Re-dislocations after arthroscopic procedure occured earlier than after open Bankart repair. An external rotation lag of 20° or more was observed more often (16%) after open than after arthroscopic surgery (3%). The Rowe score demonstrated "good" or "excellent" functional results in 87% after open and in 80% patients after arthroscopic treatment.ConclusionIn this retrospective investigation the open Bankart procedure demonstrated good functional results. The arthroscopic treatment without capsular shift resulted in a better range of motion, but showed a tendency towards more frequently and earlier recurrence of instability. Sensitive patient selection for arthroscopic Bankart repair is recommended especially in patients with more than five dislocations.
