The goal of this observational study is to learn whether the Robotic Knee Testing system can measure knee looseness in adults with an anterior cruciate ligament, or ACL, tear.
The main question it aims to answer is whether measurements from the Robotic Knee Testing system are related to the doctor's pivot shift exam grade.
Participants will complete one study visit before ACL reconstruction. During the visit, both knees will be tested in the Robotic Knee Testing system. Researchers may also review existing medical information and imaging.

Primary outcome measure(s)
Clinician-graded pivot shift — Before ACL reconstruction, during the preoperative clinical exam and/or examination under anesthesia. Clinician-graded pivot shift from 0 to 3, obtained from the treating orthopedic surgeon's preoperative clinical exam and/or examination under anesthesia before ACL reconstruction.
Association Between RKT Knee Motion Measurements and Clinician-Graded Pivot Shift Grade — RKT testing at the preoperative study visit and pivot shift grading before ACL reconstruction Relationship between Robotic Knee Testing measurements of tibiofemoral motion and clinician-graded pivot shift grade from 0 to 3. RKT measurements may include tibial translation and rotation during robotic testing.
