Why vertical jumps?
In our previous work, we found that vertical jump performance (height) is a more representative metric for knee function than horizontal hop performance (distance) in healthy individuals.

Triple hop for distance as a decision to #RTS after #ACLR.

Why triple hop?
During many sports, it is unusual for an athlete to be required to make a single movement such as an isolated jump or hop.
Triple hop provides additional information about the patient’s ability to absorb and release energy during consecutive plyometric loading.

Are you using hop distance as decision to #RTS after #ACLR?

We measured athletes after #ACLR during propulsion & landing of a single leg hop for distance after they have been cleared to #RTS
During propulsion symmetry in work done by the knee is only 69% & during landing it’s 81%, despite achieving 97% of hop distance
During propulsion symmetry in work done by the knee is only 69% & during landing it’s 81%, despite achieving 97% of hop distance
The relatively large between-leg knee work difference is easy to miss as the knee joint contributes little (12%) to propulsion in a single hop for distance.
Hop testing after #ACLR – horizontal (distance) is easier to measure than vertical (height) but are they the same?

During a vertical hop, the hip, knee, and ankle contribute almost equally, during push-off (height achieved) and landing (force absorption).
Horizontal hop is very different.
Work during propulsion (=distance achieved): knee contributes only 13% but the landing phase (absorption) is done 2/3 by the knee.

@MarkusWalden In their database:
- Few career-ending injuries (1.8%)
- Approx 7% retear rate w/in 1 yr post #ACLR
Are these re-injuries failures? Or a deliberate high-risk decision? Interesting question.
