When are you strong enough after ACLR? What do you tell your patients when they ask?<\/strong><\/p>\n\n\n\n

After attending another great Sportskongress, there was a lot of focus on LSI not being predictive for secondary ACL injury. However, no one could answer the question: when is someone strong enough? What are the goals? What do you tell the patient? Many RCTs have also found a beneficial effect of one treatment compared to another, but forgot to mention that both groups were either still weak or strong.<\/p>\n\n\n\n

Van Melick and colleagues tried to answer this question by conducting a scoping review on \u201cQuadriceps and Hamstrings Strength Reference Values for Athletes With and Without Anterior Cruciate Ligament Reconstruction Who Play Popular Pivoting Sports, Including Soccer, Basketball, and Handball.<\/p>\n\n\n\n

Similarly, results were presented at the World Physiotherapy Conference in 2022, where results from Aspetar cohort looked at quadriceps and hamstrings strength every 6 weeks up to 9 months post-op.<\/p>\n\n\n\n

In the Aspetar ACL Protocol, it is also suggested that athletes (Tegner scale 8-10) should achieve Peak Isokinetic Concentric Torque > 300% BW for the quadriceps and > 175% BW for the hamstrings, while non-athletes (Tegner scale 5-7) should achieve Peak Isokinetic Concentric Torque > 260% BW for the quadriceps and > 160% BW for the hamstrings.<\/p>\n\n\n\n

Another relevant factor besides the Tegner scale is age. We see a drop in strength when stratified by age.<\/p>\n\n\n\n

Question:<\/p>\n\n\n\n

A patient comes in and tells you he has been measured at 2.0 quadriceps BW\/Nm and 1.3 hamstrings BW\/Nm with a limb symmetry index of 10%. What will you tell the patient?<\/p>\n\n\n\n
