Key takeaways:
- Arthroscopic anatomic glenoid reconstruction had a lower redislocation rate vs. Bankart repair.
- Arthroscopic anatomic glenoid reconstruction also had better anterior-posterior remodeling.
DENVER — According to results presented here, arthroscopic anatomic glenoid reconstruction may have a lower redislocation rate compared with Bankart repair among patients with recurrent instability.
“[Arthroscopic anatomic glenoid reconstructions] AAGRs at 5 years have a redislocation rate similar to a Latarjet,” Ivan Ho-Bun Wong, MD, FRCS(C), MAcM, Dip. Sports Med, said in his presentation at the American Orthopaedic Society for Sports Medicine Annual Meeting. “It is more stable than a Bankart repair at 5 years.”
In a retrospective chart review with a minimum 5-year follow-up, Wong and colleagues analyzed data for 72 patients with less than 25% glenoid bone loss treated with either an AAGR (n = 41) or a Bankart repair (n = 31). They considered the redislocation rate as the primary outcome measure and also reviewed postoperative complications, revision surgeries, radiographic outcomes and patient-reported outcomes.
According to Wong, patients who underwent AAGR had a redislocation rate of 2.4% at 5 years compared with 17.8% in the Bankart group. In addition, Wong said CT scans showed patients with AAGRs “had remodeled back to a normal anterior to posterior dimension of the glenoid,” while patients who underwent Bankart repair roughly remained the same.
Wong also noted patients who underwent AAGR met minimal clinically important difference thresholds at a higher percentage than patients in the Bankart group. However, the AAGR group had a higher rate of hardware irritation compared with the Bankart group.
Neither group showed any further progression to osteoarthritis, and both groups had improvements in patient-reported outcomes, according to Wong.
“Our future directions for a randomized controlled trial will hopefully be able to be presented to you next year from AAGR to Bankart,” Wong concluded.
