Purpose: The gravity-assisted pivot-shift (GAPS) test is a newly advocated test for anterior cruciate ligament (ACL) injury. We retrospectively investigated the relationships between the result of preoperative GAPS test and the function of the reconstructed ACL using autogenous hamstring tendon grafts.

Methods: Seventy-eight patients with unilateral ACL injury and a minimum of 1-year follow-up were enrolled in this study.

Gravity-assisted pivot-shift (GAPS) test is a newly advocated test for anterior cruciate ligament (ACL) injury. It induces anterolateral rotatory instability with valgus stress to the knee applied by gravitational force during patient's active knee motion. We investigated prospectively the relationships between the results of the GAPS test and the possible contributory factors and sought to clarify the determinant factors of the GAPS test.
