After examining documented cases of second ACL injuries, researchers found that patients can be divided into three functional subgroups based on the Rule of Thirds concept. This biomechanical classification may help identify athletes at risk for further injury and accelerate their return to play after ACL reconstruction.
Researchers found that tendons, not muscles, are the key site where increased mechanosensitivity translates to better running and jumping capabilities. High expression of the calcium-ion channel mechanoreceptor coincided with wider tendons composed of larger collagen fibrils.
