How Do Patients Fare 10 Years after Arthroscopic Bankart Surgery?

    Glenohumeral instability repair is a challenging procedure, with early success often confounded by increasing recurrence rates with longer-term follow-up.

    Long-term outcomes of open Bankart repair for instability are know, but similar data are not available for arthroscopic suture anchor repair.

    At ICJR’s Pan Pacific Orthopaedic Congress, Stephen C. Weber, MD, sought to shed some light on long-term outcomes of the arthroscopic procedure with a report on 40 of his patients who had undergone that procedure for instability repair between 1996 and 2003.

    He found that by 10 years afer the proccedure, 23% of patients experienced subluxation or dislocation, with only one third of those incidents occurring within the standard 2-year follow-up. More than half (65%) of patients required no further surgery despite at least 1 recurrent instability episode.

    Functional scores averaged in the good to excellent range at follow-up, even with the high number of patients experiencing instability. Activity modification was the major predictor of success – higher-demand patients were more likely to sublux or dislocate than lower-demand patients (P<0.02). No other variable achieved statistical significance.

    “Glenohumeral instability remains a difficult problem despite advances in surgical techniques,” Dr. Weber concluded.

    “While standard shoulder scores remain high, 2-year follow-up will only capture one third of recurrent instability, and the ultimate predictor of long-term success remains activity modification.”
