Functional performance was assessed by the distance achieved during a one\u2010leg hop test and the maximum number of knee bends performed in 30 s. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was used to evaluate self\u2010reported outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall changes from 2 to 4 years post APM did not differ in maximal muscle strength, rapid force capacity, and functional performance between the operated and contra\u2010lateral leg of patients or control legs. However, secondary analysis showed a difference in change in knee extensor MVC resulting in a 6% difference between the operated and contra\u2010lateral leg of patients at follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>No differences in longitudinal changes were observed from 2 to 4 years post APM between patients and controls. The secondary finding of differential changes over time in knee extensor MVC between the operated and contra\u2010lateral leg partly confirm our hypothesis that differences in muscle strength may evolve from 2 to 4 years post APM. This differential change may represent an initial sign of an evolving lower limb muscle asymmetry, which may play a role in the development of knee OA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level
