Adductor Longus Tenotomy & the BKFO Test

"The intervention included in this study is part of routine medical care, and not assigned as a result of study participation. This study includes only the addition of a measurement; the bent knee fall out test. Therefore, we believe this study design is observational, and in line with the provided observation study design definition: Observational: studies in human beings in which biomedical and/or health outcomes are assessed in predefined groups of individuals. Participants in the study may receive diagnostic, therapeutic, or other interventions, but the investigator does not assign specific interventions to the study participants. This includes when participants receive interventions as part of routine medical care, and a researcher studies the effect of the intervention.~See uploaded study protocol for further details."
