Editorial Comment on the Article by M.S. Ryazantsev et al. “Influence of Posterior Tibial Slope on the Risk of Recurrence After Anterior Cruciate Ligament Reconstruction”

The failure of ACL reconstruction may occur not only due to repeated injury but also technical errors or biological reasons. The individual patterns of knee morphology addressed in the study of M.S. Ryasantsev et al., particularly tibial slope. Statistically significant difference does not necessarily mean that it leads to clinical impact on the patient. Therefore, all findings should be discussed from the point of minimal clinically relevant difference, especially if the study is underpowered.
