Clinical Trial Summary

The purpose of this research study is to examine the impact of one type of commonly used birth control pill on blood levels of relaxin and measure changes in knee movement to determine whether there are changes in joint instability (indicating the knee is less stable) that may predispose female athletes to injury. Women not on hormonal birth control will also be enrolled to analyze differences between athletes on and not on birth control and to evaluate typical relaxin levels and knee laxity when birth control pills are not used.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Ligamentous injury	ligament rupture or tear occurrence per athlete enrolled	over the course of 1 year
Secondary	Serum relaxin level	level of relaxin measured in each subject	baseline, 4 month visit
Secondary	Anterior Knee Laxity	Anterior Knee laxity will be evaluated using the KT-2000 and measured in millimeters of anterior translation of the tibia relative to the femur	baseline, 4 month visit
Secondary	Hip rotation during a single-legged drop	Hip flexion, adduction, and internal/external and coronal plane rotation of the knee measured during a singled-legged drop using motion tracking equipment.	baseline, 4 month visit
Secondary	Knee rotation during a single-legged drop	Hip flexion, adduction, and internal/external and coronal plane rotation of the knee measured during a singled-legged drop using motion tracking equipment.	baseline, 4 month visit
Secondary	Joint Hypermobility	Beighton score will be used to assess overall joint laxity. The Beighton score is on a nine-point scale that is based on 5 joint maneuvers. The maximum score is 9, which indicates hyperlax. A score of zero indicates tight joints.	baseline, 4 month visit
