What this trial studies
This study evaluates the reliability, validity, and responsiveness of the German version of the Patient Rated Tennis Elbow Evaluation (PRTEE) questionnaire in patients diagnosed with lateral epicondylitis. Participants will complete the PRTEE questionnaire before receiving an autologous conditioned plasma (ACP) injection, again six weeks post-treatment, and a final assessment 2-11 days later. The study aims to provide statistical analyses to confirm the effectiveness of the questionnaire in assessing treatment outcomes for tennis elbow.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older diagnosed with lateral epicondylitis who are receiving their first ACP treatment.
Not a fit: Patients who lack German language skills or have conditions that prevent accurate evaluation will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a validated tool for better assessing treatment outcomes in patients with tennis elbow.
How similar studies have performed: While the approach of validating a questionnaire is common, the specific focus on the German version of the PRTEE is relatively novel.
