The aim of the present study was to evaluate the validity of a new arthrometer in the outpatient setting, with the hypothesis that it had good validity in terms of reliability and diagnostic accuracy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Seventy\u2010eight subjects (39 with ACL injury and 39 with normal ACL) were tested. ATT was assessed by means of the Lachman test at 30\u00b0 of flexion with a new testing device (BLU\u2010DAT) under three different loading conditions: 7\u00a0kg (69\u00a0N), 9\u00a0kg (88\u00a0N) and maximum (MMT). The tests were performed on both knees to obtain SSD. In the ACL injury group, the tests were performed by two examiners and one of them repeated a second test series. Inter\u2010 and intra\u2010observer reliability were assessed with the intraclass correlation coefficients (ICCs) for the average SSD measures. In the normal\u2010ACL group, the analysis was performed with the same testing setup. Side\u2010to\u2010side difference measures of the two groups at every loading condition were compared by Student\u2019s <jats:italic>t<\/jats:italic> test. Data of test series were dichotomized based on the threshold value of 3\u2010mm SSD as pathological ATT and 2\u2009\u00d7\u20092 contingency tables were used to assess diagnostic accuracy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The ICCs for intra\u2010observer reliability at 7\u2010kg (69\u00a0N), 9\u2010kg (88\u00a0N) and MMT measurements were 0.781, 0.855 and 0.913, respectively. The ICC for inter\u2010observer reliability at 7\u2010kg (69\u00a0N), 9\u2010kg (88\u00a0N) and MMT measurements were 0.701, 0.845 and 0.834, respectively. Comparison between the two groups showed a significant mean difference ranging from 3.4\u00a0mm for 7\u2010kg (69\u00a0N) load to 4.6\u00a0mm for MMT. Overall accuracy ranged from 84.6% for 7\u2010kg load to 98.7% for MMT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The BLU\u2010DAT has proven to be an instrument with good intra\u2010 and inter\u2010observer reliability and very good accuracy in the diagnosis of ACL injuries in the outpatient setting. So, the BLU\u2010DAT can be a new useful tool in everyday clinical practice to assist in the diagnosis of ACL injury.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>II.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-023-07534-5","type":"journal-article","created":{"date-parts":[[2023,8,8]],"date-time":"2023-08-08T12:01:45Z","timestamp":1691496105000},"page":"4782-4790","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["BLU\u2010DAT: a new reliable and accurate arthrometer for measuring anterior knee laxity"],"prefix":"10.1002","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7329-9360","authenticated-orcid":false,"given":"Alessandro","family":"Colosio","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--><!--<institution-id institution-id-type=\"ROR\">https:\/\/ror.org\/02q2d2610<\/institution-id>--> Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health University of Brescia Brescia Italy"},{"name":"<!--<label>4<\/label>--> ASST Spedali Civili, UOC Clinica Ortopedica Piazzale Spedali Civili 1 25123 Brescia BS Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandra","family":"Scaini","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--><!--<institution-id institution-id-type=\"ROR\">https:\/\/ror.org\/02q2d2610<\/institution-id>--> Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health University of Brescia Brescia Italy"},{"name":"<!--<label>2<\/label>--> Department of Bone and Joint Surgery Spedali Civili Brescia Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcello","family":"Motta","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--><!--<institution-id institution-id-type=\"ROR\">https:\/\/ror.org\/02q2d2610<\/institution-id>--> Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health University of Brescia Brescia Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Paderno","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Department of Bone and Joint Surgery Spedali Civili Brescia Italy"},{"name":"<!--<label>4<\/label>--> ASST Spedali Civili, UOC Clinica Ortopedica Piazzale Spedali Civili 1 25123 Brescia BS Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maristella F.","family":"Saccomanno","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--><!--<institution-id institution-id-type=\"ROR\">https:\/\/ror.org\/02q2d2610<\/institution-id>--> Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health University of Brescia Brescia Italy"},{"name":"<!--<label>2<\/label>--> Department of Bone and Joint Surgery Spedali Civili Brescia Italy"},{"name":"<!--<label>4<\/label>--> ASST Spedali Civili, UOC Clinica Ortopedica Piazzale Spedali Civili 1 25123 Brescia BS Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierfrancesco","family":"Bettinsoli","sequence":"additional","affiliation":[{"name":"<!--<label>3<\/label>--> Department of Orthopaedics and Traumatology Clinica S.
