A multicentre, retrospective and observational study to evaluate safety and functional outcomes of arthroscopic shoulder ligament repair using Sironix suture anchor

Background: Arthroscopic shoulder ligament repair is one of the most performed procedures in the orthopaedic specialty. Suture anchor devices are used in arthroscopic surgeries to reattach ligaments or other soft tissues to bone. The goal of this study was to evaluate the safety and functional outcomes after shoulder ligament repair. Methods: This is a multicentric, retrospective, observational study conducted on patients who underwent primary arthroscopic shoulder ligament tear repair between April 2018 to July 2022, using Sironix suture anchors at Kumaran Hospital and Rela Institute, Chennai, Tamil Nadu, India, and DNV Ortho Care Hospital, Dharmapuri, Tamil Nadu, India. A total of 75 patients were included. Post-surgery measurements of functional outcomes were performed using the PENN shoulder score, simple shoulder test questionnaire, shoulder pain and disability index, and single assessment numerical evaluation. Adverse events were recorded. Results: At post-surgery follow-up visits, there was a significant improvement in the functional outcomes of all the patients. The PENN shoulder score had a mean (SD) pain score of 92.04 (7.50), a satisfaction score of 91.87 (8.00), and a function score of 93.18 (6.16), respectively. The mean (SD) SST score and SPADI score was 88.9 (9.7), and 2.8 (2.79) respectively. The SANE mean (SD) values of the operated joint and opposite joint were 91.0 (7.31) and 98.1 (4.26) respectively with a p value of 0.0001. Conclusions: Based on the study results, arthroscopic shoulder ligament repair with Sironix suture anchor resulted in good and desirable functional outcomes with no major adverse events and improved quality of life.
