Arthroscopic anatomic glenoid reconstruction has a lower rate of recurrent instability compared to arthroscopic Bankart repair while otherwise maintaining a similar complication and safety profile

The primary purpose of this study was to determine the frequency and type of complications, including subluxation, infection, hardware complication, graft/glenoid fracture, chondrolysis, neurovascular deficits and stiffness following an Arthroscopic Bankart Repair (ABR) or an Arthroscopic Anatomic G...

Zusammenfassung:The primary purpose of this study was to determine the frequency and type of complications, including subluxation, infection, hardware complication, graft/glenoid fracture, chondrolysis, neurovascular deficits and stiffness following an Arthroscopic Bankart Repair (ABR) or an Arthroscopic Anatomic Glenoid Reconstruction (AAGR) using a distal tibia allograft for recurrent anterior shoulder instability. Secondary purposes were to determine the frank dislocation rate and the associations of post-operative complications with demographic patient factors. Demographic and clinical data were reviewed using means ± standard deviations or frequencies in patients with recurrent anterior shoulder instability who underwent either an ABR or an AAGR. Post-operative patient records were analysed to identify any post-operative complications. The numerical variables of the two groups were compared using the independent t-test or Mann–Whitney U test. Categorical variables and complications were tested using the chi-square test, Fisher’s exact test, or the two-sided Monte Carlo test with a significance level of 0.05. We included 174 patients in this cohort, with 61.5% of patients receiving ABR and 38.5% receiving AAGR. Most of our patients were male (70.1%) with an average age of 23.41 ± 8.26 years in the ABR group and 29.37 ± 13.54 years in the AAGR group (p = 0.001). The two groups were similar with respect to their post-operative complication rates when excluding frank dislocation (ABR: 11%, AAGR: 12%). The AAGR group had statistically significantly higher rates of hardware removal compared to the ABR group (p = 0.004). The ABR group had 25 post-operative frank dislocations, with none reported in the AAGR cohort (p
