Use of the Liverpool Elbow Score as a postal questionnaire for the assessment of outcome after total elbow arthroplasty.

The Liverpool Elbow Score (LES) is a newly developed, validated elbow-specific score. It consists of a patient-answered questionnaire (PAQ) and a clinical assessment. The purpose of this study was to determine whether the PAQ portion of the LES could be used independently as a postal questionnaire for the assessment of outcome after total elbow arthroplasty and to correlate the LES and the Mayo Elbow Performance Score (MEPS). A series of 51 total elbow replacements were reviewed by postal questionnaire. Patients then attended the clinic for assessment by use of both the LES and the MEPS. There was an excellent response rate to the postal questionnaire (98%), and 44 elbows were available for clinical review. Good correlation was shown between the LES and the MEPS (Spearman correlation coefficient, 0.84; P < .001) and between the PAQ portion of the LES and the MEPS (Spearman correlation coefficient, 0.76; P < .001). We conclude that there is good correlation between the LES PAQ component and the MEPS, suggesting that outcome assessment is possible by postal questionnaire.
