The study translated Oxford Knee Score (OKS) questionnaire into Yoruba Language and assessed the reliability of both English and Yoruba version of the translated OKS scores for effective management of knee osteoarthritic patients among the Yoruba language speakers.

Forty-five radiographically confirmed knee osteoarthritis patients participated in this study. The original English version of the OKS was translated into Yoruba Language. The translated version was used as the Yoruba version. This Yoruba-translated version was retranslated to English language to ensure accuracy. Each subject was administered the original and the retranslated versions of the OKS questionnaire, after two weeks another copy of the retranslated questionnaire was re-administered to each participant to test for its reliability.

Data was analyzed using descriptive and inferential statistics at alpha level of 0.05.

Results showed that there was a positive relationship (r = 0.970, p ˂ 0.001) between the scores of original version and the retranslated, there was also positive relationship (r = 0.980, p ˂ 0.001) between the scores of the translated version of the OKS and another copy of it that was re-administered after two weeks. Crohnbach’s alpha for the total population was 0.96 showing that the questionnaire had strong internal consistency.

It can be concluded from the study that the Yoruba version of the Oxford Knee Score (OKS) questionnaire is reliable and valid as an outcome measure for assessing knee osteoarthritis patients.
