Abstract
The aim of this retrospective study was to compare recurrence rates followi ng transglenoid labrum refixation or fixation using the suture anchor (FAST ak, Arthrex, Naples, FL) technique. Additionally parameters that apparently influence the rate of redislocation were investigated. There were 183 pati ents with post-traumatic anterior shoulder instability treated with an arth roscopic labrum refixation; 108 patients (66.3%) were stabilized with the t ransglenoid suture technique (group I) and 55 patients (33.7%) with the sut ure anchor (FASTak) technique (group II). The average follow-up was 4.5 yea rs (range, 2.0 to 7.9 years) in group I and 3.2 years (range, 2.0 to 5.0 ye ars) in group II. The Rowe score increased from a preoperative average of 3 5.0 points in group I and 35.4 points in group II to a postoperative averag e of 68.3 points in group I and 84.6 points in group II (P < .01), There wa s recurrence in 35 patients (32.4%) in group I and 9 patients (16.4%) in gr oup II (P < .05), All incidents of redislocation occurred during the first 21 postoperative months; 58.4% of the patients (n = 63) in group I and 16.4 % of the patients in group II (n = 9) had to reduce their sporting activity (P < .001). Independent of the type of surgery, there was a significant co rrelation of the postoperative rate of redislocation and age (P < .001), nu mber of preoperative dislocations (P < .01), and degree of labrum lesion (P < .001). No correlation with the rate of redislocation was shown for gende r, handedness, dislocation-operation interval, degree of Hill-Sachs lesion, or number of transglenoid sutures or anchors. Concerning post-traumatic an terior shoulder instability, the arthroscopic labrum reconstruction with th e suture anchor (FASTak) technique was superior to the transglenoid techniq ue but has not yet achieved the level of success obtained by open surgery. With fewer than 5 preoperative redislocations after a first traumatic shoul der dislocation, the arthroscopic treatment is recommended. In cases of mor e frequent preoperative dislocations, open surgery in combination with a ca psular shift should be performed.
