There are four still photos taken to analyze movement in the following areas:

Hyperextension: we assess hyperextension by looking at the athlete from the side. This picture provides a good visual depiction of whether hyperextension of the knee is present.

Toe-Touch: this photo represents the athlete jumping off the box at initial touch down with the knee in its most fully extended position while the athlete can still control the width of their stance. The measurement calculates the width in mm between the hip, knee, and ankle markers.

Landing: The full squat picture was chosen because of the initial theory that the knees are in the most valgus (knock-kneed) and out-of-control position upon landing. The measurement calculates the width in mm between the hip, knee, and ankle markers respectively. Control of landing is demonstrated by a knee measurement of 60% or more as compared to the hip measurement of 100%

Take-Off: The picture of the take-off further analyses knee separation because it was determined that the maximum valgus (knock-kneed) shift often does not occur until the subject prepares to jump. The measurement calculates the width in mm from the hip, knee, and ankle markers respectively. Control of landing is demonstrated by a knee measurement of 60% or more as compared to the hip measurement of 100%.

Summary: No ACL sumary at this time.
