Abstract

Abstract Background The shoulder joint is the joint with the most dislocations in all joints. The arthroscopic surgery method is considered the gold standard because it creates less soft tissue damage, shorter hospitalization and surgery time, and less restriction of movement after surgery in shoulder instability. Anterior single portal technique has become popular recently. In this study, it was aimed to evaluate the results of the anterior single portal repair technique using "birdbeak". Methods In the total of 40 patients who underwent arthroscopic surgery for traumatic recurrent anterior shoulder dislocation between January 2017 and February 2020, this study included 19 patients with the surgical technique of arthroscopic isolated anterior labrum tear repair using a birdbeak from the anterior single working portal. Clinical results were evaluated with the Simple Shoulder Test (SST), Rowe Score for Instability (RWS) and Oxford Shoulder Instability Score (OSIS) tests before and after surgery. The relationship between the time to surgery after the first dislocation and clinical outcomes was also examined in the study. Results The mean follow-up period of the 19 patients included in this study was 33.1 months. The mean time to surgery after the first dislocation was 18.4 months. The mean preoperative number of dislocations was 5.3. The mean number of anchors used in the repair was 2.1. No recurrent dislocations were observed after surgery. A significant difference was observed between preoperative and postoperative SST, RWS and OSIS scores (respectively, p=0.000<0.001, p=0.000<0.001, p=0.000<0.001). There was no statistically significant relationship between the time elapsed after the first dislocation and the postoperative SST, RWS, OSIS scores (respectively, p=0.43>0.05, p=0.39>0.05, p=0.31>0.05). Conclusion It has been observed that the repair technique applied using the “birdbeak” from the anterior single working portal is a successful treatment, and further studies are required due to the limited literature.
