Brief Summary

Knee injuries, especially those to the ACL, are common among physically active people. These injuries are frequently treated with surgical reconstruction (ACL reconstruction; ACLR). While ACLR restores stability it does not protect against future injury, long-term pain, disability, and arthritis associated with these injuries. Our study is going to examine new ways to provide feedback about the way people move to determine if these are better at modifying movement patterns that are known risk factors of posttraumatic osteoarthritis development than current standard treatments. If you participate, you will be asked to undergo a movement analysis in a research laboratory while you perform tasks such as walking and hopping. After this initial assessment, you will be randomly allocated to one of 2 treatment groups. Each treatment group will perform 4 weeks (3x/week) of exercises to change the way people walk. Participants will then report for follow-up movement analysis testing 1- and 4-weeks after completing the intervention.

Conditions

Anterior Cruciate Ligament Injuries; Anterior Cruciate Ligament Rupture; Anterior Cruciate Ligament Tear; Osteo Arthritis Knee

Outcome Measures

Primary Outcomes (2)

• Changes from baseline in lower extremity biomechanics during walking

  Knee and hip angles and loads measured via 3D biomechanics

  1-week post-intervention, 4-weeks post-intervention

• Knee cartilage health

  Knee cartilage thickness measured using diagnostic ultrasound imaging

  1-week post-intervention, 4-weeks post-intervention

Study Arms (2)

Internal focus of attention feedback

ACTIVE COMPARATOR

Participants will complete 12 sessions over 3 weeks receiving visual feedback in a mirror of their movement patterns.

Other: Internal focus of attention feedback

External focus of attention feedback

EXPERIMENTAL

Participants will complete 12 sessions over 3 weeks receiving visual feedback of their movement patterns from a laser.

Other: External focus of attention feedback

Interventions

Internal focus of attention feedback OTHER

Participants will complete 12 sessions over a 3-week period of functional movement retraining while receiving mirror feedback. Participants will be instructed to perform each functional task in a manner that keeps their knee in line with their toes.

Internal focus of attention feedback

External focus of attention feedback OTHER

Participants will complete 12 sessions over a 3-week period of functional movement retraining while receiving visual feedback via laser. Participants will be instructed to perform each functional task in a manner that does causes the laser to move up and down but not side-to-side.
