What this trial studies

This study compares two methods for evaluating patient-reported outcomes after knee prosthetic surgery: traditional paper questionnaires administered in an outpatient setting versus digital questionnaires sent to patients' smartphones. The aim is to assess the validity and compliance of these methods using the Oxford Knee Score, which measures knee discomfort. Patients will complete the questionnaires during pre-hospitalization visits and follow-ups at 1, 3, and 6 months post-surgery. The study will analyze differences in patient satisfaction and compliance between the two methods.

Who should consider this trial

Good fit: Ideal candidates include males and females aged 18-78 with gonarthrosis who have a Barthel scale score of 91 or higher and access to digital devices.

Not a fit: Patients with significant psychiatric issues, a history of substance abuse, or those lacking access to digital devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy and convenience of outcome assessments for knee prosthetic surgeries, leading to better patient care.

How similar studies have performed: Other studies have shown promise in using digital methods for patient-reported outcomes, suggesting this approach may be effective.
