Purpose
In this retrospective study we evaluated the short- to medium-term results after 20 Coonrad-Morrey revision total elbow arthroplasties (TEAs).
Methods
We included a consecutive series of revision TEAs performed at our institution from 2004 to 2010. At a mean follow-up of 4.4 years, patients were evaluated using the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES) and standard radiographs.
Results
The mean age at revision TEA was 65.8 years. The median time of implant survival for primary prosthesis was 9.5 years. The mean post-operative MEPS was 79. The mean OES was 58, 66 and 53 for function, pain and social-psychological dimensions, respectively. At follow-up the range of motion had improved significantly. There were two cases of radiolucent lines and two cases of minor bushing wear; however, none of the implants were clinically loose. In one case deep infection led to a further revision. Two patients had post-operative ulnar nerve paraesthesia.
Conclusions
Results after revision TEA using the Coonrad-Morrey prosthesis are acceptable with a low short- to midterm failure rate. Revision improves range of motion and provides pain relief. One case of deep infection with recurrent revision is of concern. The treatment can be used as an option for failed TEA.
