Predicting the diameter of a rectus femoris tendon graft for ACL reconstruction
Prediction of Quadrupled Rectus Femoris Graft Diameter Using Anthropometric and Tendon Parameters
This project will test a model that uses patient body measurements and tendon data to predict the diameter of a quadrupled rectus femoris graft for adults having ACL reconstruction.

What this trial studies
This observational study will collect patient anthropometric data and intraoperative tendon measurements from adults undergoing primary ACL reconstruction with rectus femoris autografts. Researchers will use multivariable regression and related statistical modeling to identify independent predictors and generate a formula to estimate quadrupled graft diameter. The model's diagnostic performance will be tested for clinically important thresholds (≥8 mm and ≥9 mm). Data may be gathered prospectively or retrospectively and validated on a separate sample.
Who should consider this trial
Good fit: Adults (18+) undergoing primary ACL reconstruction with a rectus femoris tendon autograft who have complete anthropometric and intraoperative measurement data.
Not a fit: Patients having revision ACL surgery, receiving non-rectus femoris grafts, under 18 years old, or lacking complete measurement data are unlikely to benefit from this model.
Why it matters
Potential benefit: If successful, surgeons could better plan graft choice and anticipate when alternative grafts or augmentation are needed, potentially reducing graft failure.
How similar studies have performed: Predictive models for hamstring tendon graft size have shown useful accuracy, but models specifically for rectus femoris grafts are novel and currently unvalidated.
