Background:
The Copeland resurfacing hemiarthroplasty (RHA) has been used
to treat patients with degenerative shoulder disease since the mid 1990’s. The
Copeland prosthesis has been linked to high revision rates and inferior patient-
reported outcome
Purpose / Aim of Study:
We investigated the 1 year post-operative patient-
reported outcome after Copeland RHA with or without AC-joint resection and
the overall revision rate
Materials and Methods:
We include all patients who had surgery with the
Copeland prosthesis at Koege Hospital Orthopaedic department in a 6 years pe-
riod from January 2008 to December 2013. The Danish Shoulder Arthroplasty
Registry (DSR) was crosschecked to identify all patients with Copeland RHA
surgery at our department in that period and to gain WOOS score one year
post-operatively. The WOOS score at one year was used to evaluate the pa-
tient-reported outcome Revision rates were obtained from the DSR and cross-
checked with the National Patient Register in january 2016
Findings / Results:
In total 137 consecutive Copeland RHA in 131 patients
were evaluated. The mean follow-up time was 4.0 years. The cohort included
48 (35%) males and 89 (65%) females. The mean age was 69.2 (± 8.8) years
at surgery. AC-joint resection was performed in 51 (37%) shoulders. In the 89
patients who returned the WOOS questionnaire at one year the median WOOS
score was 89.5 There was nió difference between those who har an ac resek-
tion and those without. 7 patients had a revision and 19 patients died prior to
December 2015.
Conclusions:
The cohort had a high patient-reported outcome after one year
and a low revision rate. We found no difference in patient-reported outcome for
patients with and without AC-joint resection. We conclude that the Copeland
prothesis is an unpredictable prothesis yeilding varied results i differeret series.
