Arthroscopic labral repair with all-suture anchors : A magnetic resonance imaging retrospective study with a 2,5-years follow-up

Aim To evaluate radiological and clinical outcomes of a case series of patients affected by glenohumeral instability (Bankart lesion) or superior labrum tear from anterior to posterior (SLAP) lesions treated by arthroscopic repair using all-suture anchors. Methods Patients were operated by a single surgeon at a single Institution. Exclusion criteria were chondral lesions of the glenoid, rotator cuff lesions, previous surgery at the index shoulder, or a bony Bankart lesion. Position and numbers of anchors used depen-ded on the dimension and type of lesion. The DASH (Disability of the Arm, Shoulder and Hand) and Constant scores were used for subjective and clinical evaluation at follow-ups (FUs); also, at 1-year FU, MRI scan was obtained to evaluate bone reaction to the implanted devices. Results Fifty-four patients were included. A mean of 2.7 devices per patient (145 in total) were implanted. Mean FU was 30 (ran-ge 12 – 48) months. No patient reported recurrent instability, nor hardware-related complications were registered. MRI analyses showed that 119 (82%) implants did not alter surrounding bone (grade 0), 26 (18%) implants were surrounded by bone oedema (grade 1), while no bone tunnel enlargement nor a bone cyst (grade 2 or 3, respectively) were registered. Conclusion This study confirmed the efficacy and safety of a spe-cific all-suture anchor system in the arthroscopic repair of the glenoid labrum for glenohumeral instability or a SLAP lesion. In the short-and mid-term period, these devices were associated with good clinical and radiological outcomes without clinical failures or reaction at bone-device interface. © 2021, Medical Association of Zenica-Doboj Canton.
