Retrospective study of 20 shoulders in 19 young patients with severe loss of external rotation after a prior anterior instability repair. It asks what happens to these overtightened shoulders and whether anterior soft-tissue release restores motion. It describes the resulting posterior subluxation and arthritis, plus the release technique used to treat it.
When you close an anterior instability repair, confirm the shoulder has at least 20 to 25 degrees of external rotation. This paper shows why: an overtight capsulorrhaphy that blocks external rotation drives the head posteriorly and erodes the posterior glenoid.
The result is capsulorrhaphy arthropathy, glenohumeral arthritis in young patients whose only real risk factor was the repair itself. Every arthritic shoulder here was 45 or younger. Watch for the patient stuck at 0 degrees of external rotation six months after an instability procedure. That patient should be warned about late arthritis and considered for anterior release.
Release alone restored motion and stability reliably. Add arthroplasty only when the arthritis is already severe. Also remember the setup pitfall: doing an anterior tightening on a truly multidirectional shoulder is what produced the worst posterior subluxations.
