This case series reports survivorship and patient-reported outcomes after arthroscopic pancapsular shift for multidirectional shoulder instability. It asks whether outcomes achieved early hold up at a minimum 5-year and mean 9-year follow-up. It also compares atraumatic versus traumatic MDI onset over the long term.
When counseling a young patient before arthroscopic pancapsular shift for MDI, this paper gives you durable numbers: roughly 82% surgical success at 8 years and only about 10% needing revision.
The key teaching point is separating subjective instability from true failure. Nearly a third of patients report feeling unstable, yet most keep acceptable outcomes and 10/10 satisfaction, and never come back to the OR.
The finding that scores do not decline between 1-2 years and 9 years directly counters the classic worry that pathologic capsular tissue stretches out over time. If the repair survives the first few years, it tends to last.
At short-term follow-up, prior work suggested traumatic-onset MDI fared better than atraumatic. This longer study found no significant difference, so counsel both groups toward similar expectations. Remember the limits: Level 4 evidence, 48% had complete serial PROs, no radiographs, and laxity was never quantified.
