Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are Italian-speaking patients aged 18 to 85 diagnosed with knee osteoarthritis and scheduled for primary total knee arthroplasty.
✕Probably not a fit
Patients with concurrent hip or spinal issues, previous knee surgeries, or congenital knee deformities may not benefit from this study.

What this trial studies
This study focuses on adapting and validating the Italian version of the Knee Society Knee Scoring System (KSS) for patients with knee osteoarthritis. The process involves translating the original English questionnaire into Italian, ensuring cultural relevance through a series of translations and back-translations. The final version will be tested on 300 Italian patients who meet specific eligibility criteria, including those scheduled for primary total knee arthroplasty. The aim is to ensure that the Italian KSS accurately reflects the patients' knee function and pain levels.
Why it matters
Potential benefit: If successful, this study could provide a reliable tool for assessing knee function in Italian-speaking patients with osteoarthritis, leading to improved patient care.
How similar studies have gone: Other studies have successfully validated similar scoring systems in different languages, indicating a promising approach for this adaptation.
