To facilitate the decision regarding a patient's return to sport, we developed a standardized and easy\u2010to\u2010use test battery to enable an objective evaluation of knee function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The test battery consisted of seven functional tests: the two\u2010leg stability test, one\u2010leg stability test (OL\u2010ST), two\u2010leg countermovement jump (CMJ), one\u2010leg CMJ (OL\u2010CMJ), plyometric jumps, speedy test and quick feet test. For each test, the reliability was determined based on the intraclass correlation coefficient. For all one\u2010leg tests, the limb symmetry index (LSI) was calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All tests showed a moderate\u2010to\u2010high reliability. Normative data from 434 participants were included in the analysis. The subjects were categorized according to age as follows: children (10\u201314 years), youth (15\u201319 years), young adults (20\u201329 years) and adults (30\u201350 years). The establishment of the functional test values allowed the classification into five normative categories. The LSI for the OL\u2010ST (98 %) indicated a better performance of the non\u2010dominant leg. In contrast, high LSI values were found for the OL\u2010CMJ (124 %), indicating a better performance of the dominant leg.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Each test was found to be reliable and simple to perform. The better performance of the non\u2010dominant leg in stability tasks must be considered when interpreting side\u2010to\u2010side differences. The established norm data from healthy individuals of each test battery represents an important basis for a clinical setting. Test results from an ACL\u2010reconstructed patient should be at least classified as a functionally average outcome to support a safe return to sports.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>IV.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-015-3529-4","type":"journal-article","created":{"date-parts":[[2015,2,17]],"date-time":"2015-02-17T04:46:09Z","timestamp":1424148369000},"page":"1273-1281","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":122,"title":["Functional assessments for decision\u2010making regarding return to sports following ACL reconstruction.
