Capsular lesions frequently seen during arthroscopic Bankart repair
Among shoulders treated with arthroscopic Bankart repair, investigators found nearly 30% also had capsular lesions and these correlated with postoperative recurrent instability.
Using operative records, still pictures and videos, researchers retrospectively reviewed capsular lesions in 172 shoulders with traumatic, anterior shoulder instability. Investigators assessed the prevalence of capsular lesions and severity of the capsular lesions. For a minimum of 2 years, the postoperative recurrence of instability in shoulders was observed. Factors that were correlated with the occurrence of capsular lesions and postoperative recurrence of instability were assessed.
There were capsular lesions in 37 shoulders. Of these, 20 were considered severe and 17 were mild. Investigators noted all capsular lesions were repaired during the arthroscopic Bankart procedure. Investigators found recurrent shoulder instability in 10 shoulders (29.4%) after 2-years follow-up. Six of these shoulders had severe lesions and four shoulders had mild lesions.
According to researchers, shoulders with capsular lesions had a significantly higher recurrence rate compared to those without capsular lesions; however, no difference was seen between cases with severe lesions vs. mild lesions.
Capsular lesions were seen more frequently in patients 30 years or older, patients with complete dislocation and patients who had coexisting Hill-Sachs lesions, regardless of the sports patients played. Patients who were younger than 30 years and were competitive athletes saw significantly higher rates of recurrent instability. – by Monica Jaramillo
