Part I: development of a new test battery [Elektronische Daten] [Carolin Hildebrandt, Lisa Müller, Barbara Zisch, Reinhard Huber, Christian Fink, Christian Raschner] Purpose: Return to activity remains the most common concern following an injury. To facilitate the decision regarding a patient's return to sport, we developed a standardized and easy-to-use test battery to enable an objective evaluation of knee function. Methods: The test battery consisted of seven functional tests: the two-leg stability test, one-leg stability test (OL-ST), two-leg countermovement jump (CMJ), one-leg CMJ (OL-CMJ), plyometric jumps, speedy test and quick feet test. For each test, the reliability was determined based on the intraclass correlation coefficient. For all one-leg tests, the limb symmetry index (LSI) was calculated. Results: All tests showed a moderate-to-high reliability. Normative data from 434 participants were included in the analysis. The subjects were categorized according to age as follows: children (10-14years), youth (15-19years), young adults (20-29years) and adults (30-50years). The establishment of the functional test values allowed the classification into five normative categories. The LSI for the OL-ST (98%) indicated a better performance of the non-dominant leg. In contrast, high LSI values were found for the OL-CMJ (124%), indicating a better performance of the dominant leg. Conclusion: Each test was found to be reliable and simple to perform. The better performance of the non-dominant leg in stability tasks must be considered when interpreting side-to-side 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-reconstructed patient should be at least classified as a functionally average outcome to support a safe return to sports. Level of evidence: IV.
