Prospective cohort study of 269 shoulders in 223 patients with primary frozen shoulder. Used the Oxford Shoulder Score to characterize long-term outcomes at mean 4.4-year follow-up. Asked: who recovers fully, who doesn't, and what predicts it?
The traditional teaching that frozen shoulder universally self-resolves to full function is wrong. This study — the largest long-term cohort at the time of publication. Shows that 41% carry some symptoms beyond 4 years, and 6% are left with significant pain and functional loss.
When you see a new frozen shoulder patient, counsel them with these numbers: roughly 6 in 10 reach near-normal, but 4 in 10 will have lingering symptoms, almost always mild pain. Tell them the window for meaningful improvement is roughly 3 years. After that, what they have is likely what they'll keep.
When a patient describes the first 6 months as unbearable, treat that as a red flag. They carry a 7-fold higher risk of severe long-term disability and warrant earlier escalation. Whether that means hydrodistension, MUA, or arthroscopic release. Rather than extended watchful waiting.
One practical note: bilateral involvement affects 1 in 5 patients, so counsel them about contralateral shoulder risk at every visit.
