Abstract

Objectives

To evaluate relationships between patient-reported outcomes and lower extremity biomechanics associated with risk for second ACL injury among individuals with ACL reconstruction (ACLR).

Design

Cross-sectional study.

Setting

Research laboratory.

Participants

20 individuals with primary, unilateral ACLR (10 female, age = 20.1 ± 2.0 years, median time from surgery = 29.6 [IQR = 9.1–53.3] months).

Main outcome measures

Participants completed the International Knee Documentation Committee Subjective Knee Evaluation, Tampa Scale of Kinesiophobia (TSK-11), and Veterans RAND 12-Item Health Survey. Three-dimensional biomechanics were evaluated at peak vertical ground reaction force (vGRF) and as peak kinematic and kinetics within the first 100 ms of landing from a drop vertical jump.

Results

Higher TSK-11 scores associated with lesser hip flexion angles (r = −.723, P < .001), lesser knee flexion angles (r = .561, P = .010), and greater internal knee abduction moments (ρ = −.606, P = .005) at peak vGRF. These relationships remained significant when correcting for multiple tests and controlling for time from surgery and biological sex.

Conclusions

Kinesiophobia, but not self-reported knee function or health-related quality of life, is associated with aberrant landing biomechanics when the largest magnitudes of vertical force were applied to the knee. Individuals with greater kinesiophobia may adopt a stiffer landing profile with increased medial knee compartment loading, potentially increasing risk for second ACL injury.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
