Functional Tests Assessing Return to Activity after Anterior Cruciate Ligament Reconstruction

초록

PURPOSE: A successful return to activity following anterior cruciate ligament reconstruction is the primary goal for athletes and physically active populations who underwent the surgery. However, functional tests that could be utilized for deciding return to activity are not well-described. Therefore, we reviewed currently suggesting functional tests and the effectiveness of each tests. METHODS: In this review, we summarized the patient oriented subjective functional measures, objective functional tests, a functional test battery, and a general pass and fail criteria for functional tests. RESULTS: There are various subjective and objective functional measures to assess ACLR patients’ level of knee function. The concept of a functional test battery that is the combination of various functional tests is more sensitive to detect patient’s readiness to return. Eighty-five to ninety percent of limb symmetry index score is frequently applied as the pass and fail criteria for functional test. CONCLUSIONS: Various researches suggested functional tests that clinicians could be applied to their patients for return to activity safely. Despite the use of various functional tests, the risk for subsequent knee problems remains elevated in ACLR individuals. Therefore, it is necessary to investigate the usefulness of functional tests to identify individuals that are at greatest risk for subsequent knee injury.
