Most Shoulder Replacements Last More Than 10 Years

FRIDAY, Aug. 28, 2020 -- About 90 percent of shoulder replacements last for longer than 10 years, and patient-reported outcome measures show sustained benefits, according to a review published online Aug. 26 in The Lancet Rheumatology.

Jonathan P. Evans, M.D., from the University of Exeter in the United Kingdom, and colleagues conducted a systematic review and meta-analysis for case series and registry data reporting 10-year or longer survival of total shoulder replacements, humeral hemiarthroplasties, and reverse total shoulder replacements. Nine articles, reporting 10 series, were eligible for analysis of survival and six articles were eligible for analysis of patient-reported outcomes.

The researchers found that the 10 series reported all-cause survival of 529 total shoulder replacements and 364 humeral hemiarthroplasties. The estimated 10-year survival was 94.6 and 90.4 percent for total shoulder replacement and humeral hemiarthroplasties, respectively. The pooled registry 10-year survival was 92 and 85.5 percent for total shoulder replacement and humeral hemiarthroplasties, respectively, and 94.4 and 93.6 percent for reverse total shoulder replacement in patients with osteoarthritis and patients with rotator cuff arthroplasty, respectively. Substantial improvement was seen from baseline scores in pooled 10-year patient-reported outcome measures, with a standardized mean difference of 2.13.

"Patients had sustained and marked benefit to 10 years," the authors write. "This information should be reassuring for patients, health professionals, and commissioners of health services."

Two authors disclosed financial ties to the medical device industry.
