Internal BraceACL ReconstructionPatients will undergo ACL Reconstruction (ACLR) with an internal brace. Patients will undergo standard perioperative protocol and be followed at typical time points after surgery (2 weeks, 6 weeks, 3 months, 6 months, 12 months). At 12 months postoperative, a follow-up MRI will be obtained to evaluate healing and at 12 months and 24 months follow up KT-1000 testing will be conducted.

Primary Outcome Measures
NameTimeMethod
Side to side difference in laxity as measured by the KT-1000 ArthrometerMonth 24 Post-Operation

The KT-1000 knee arthrometer (KT-1000) is an objective instrument to measure anterior tibial motion relative to the femur for anterior cruciate ligament (ACL) reconstruction. The side-to-side differences comparing the injured and normal extremity allow the determination of a diagnosis of increased anterior-posterior laxity. A side-to-side difference of less than 3mm at 30lb and the manual maximum is considered normal. A side-to-side difference between 3 and 5mm is considered a grey area. A side-to-side difference of more than 5mm is considered diagnostic of an ACL tear.

Secondary Outcome Measures
NameTimeMethod
Pivot Shift GradeMonth 24 Post-Operation

The Pivot Shift test is a dynamic, passive test to assess the rotational instability of the Anterior Cruciate Ligament in the knee.

Pivot shift grades include: equal/0 (negative); glide/1; clunk/2; gross/3. A positive grade indicates injury to the Anterior Cruciate Ligament.

Tegner Activity Level ScaleMonth 24 Post-Operation

The Tegner activity level scale is a scale that aims to provide a standardized method of grading work and sporting activities. The Tegner activity level scale is a graduated list of activities of daily living, recreation, and competitive sports. The patient is asked to select the level of participation that best describes their current level of activity and that before injury.

A score of 0 represents sick leave or disability pension because of knee problems, whereas a score of 10 corresponds to participation in national and international elite competitive sports. A score \>6 can only be achieved if the person participates in recreational or competitive sport.

Change from Baseline in Visual Analogue Scale (VAS) - Pain Score at Month 24 Post-OperationBaseline, Month 24 Post-Operation

Participants rate their pain on a scale from 0 (no pain) to 10 (worst pain imaginable); the response is the total score.

Change from Baseline in International Knee Documentation Committee (IKDC) Survey at Month 24 Post-OperationBaseline, Month 24 Post-Operation

This is a survey taken by patients to report how their knee is working for them. The IKDC is graded by adding the results and converting the result to a number on a scale from 0 to 100. Scores range from 0 (lowest level of function and highest level of symptoms) to 100 points (highest level of function and lowest level of symptoms).

Change from Baseline in International Knee Documentation Committee (IKDC) Survey at Month 12 Post-OperationBaseline, Month 12 Post-Operation

This is a survey taken by patients to report how their knee is working for them. The IKDC is graded by adding the results and converting the result to a number on a scale from 0 to 100. Scores range from 0 (lowest level of function and highest level of symptoms) to 100 points (highest level of function and lowest level of symptoms).

Change from Baseline in Lysholm Knee Scoring System Score at Month 12 Post-OperationBaseline, Month 12 Post-Operation

The Lysholm Knee Scoring System is an 8-item assessment of the prevalence of knee problems. The total score ranges from 0-100; scores between 95 and 100 are regarded as exceptional, 84 and 94 as acceptable, 65 to 83 as fair, and less than 65 as poor.
