Determinants of self\u2010efficacy of knee function 1 year after ACL reconstruction have been found to be the patients\u2019 internal locus of control and knee symptoms in sports and recreation. The predictive ability of perceived self\u2010efficacy of knee function measured by the K\u2010SES has not been studied in terms of patient outcome after an ACL reconstruction. The purpose of this study was to explore the potential for pre\u2010operative self\u2010efficacy of knee function measured by the K\u2010SES to predict patient outcome in terms of physical activity, knee symptoms and muscle function 1 year after an ACL reconstruction. Thirty\u2010eight patients were evaluated for outcome in terms of physical activity with the Tegner activity scale and the physical activity scale (PAS), knee symptoms with the Lysholm knee scoring scale and the knee injury and osteoarthritis outcome score (KOOS) and knee function with ability tests for muscle function 1 year after ACL reconstruction. Multiple regression and logistic multiple regression analysis were used to evaluate the K\u2010SES as a possible predictor of outcome. The patients\u2019 present perceived self\u2010efficacy of knee function (K\u2010SES<jats:sub>Present<\/jats:sub>) pre\u2010operatively was a significant predictor (<jats:italic>P<\/jats:italic> = 0.016) of the patients returning to their intensity and frequency of physical activity (PAS) 1 year after ACL reconstruction, when adjusted for age, gender and pre\u2010injury physical activity level (Tegner<jats:sub>Pre\u2010injury<\/jats:sub>) (odds ratio = 2.1). The patients\u2019 perceived future self\u2010efficacy of knee function (K\u2010SES<jats:sub>Future<\/jats:sub>) pre\u2010operatively was a significant predictor (<jats:italic>P<\/jats:italic> = 0.045) of their self\u2010rated knee function in sports\/recreational activities (KOOS<jats:sub>Sports\/recreation<\/jats:sub>) at the 1\u2010year follow\u2010up, when adjusted for age, gender and Tegner<jats:sub>Pre\u2010injury<\/jats:sub> (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> =0.25). The pre\u2010operative K\u2010SES<jats:sub>Future<\/jats:sub> was also a significant predictor (<jats:italic>P<\/jats:italic> = 0.023) of the patients\u2019 knee\u2010related quality of life (KOOS<jats:sub>Qol<\/jats:sub>), at the 1\u2010year follow\u2010up, when adjusted for age, gender and Tegner<jats:sub>Pre\u2010injury<\/jats:sub> (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> =0.23). The pre\u2010operative K\u2010SES<jats:sub>Future<\/jats:sub> was furthermore a significant predictor of an acceptable outcome 1 year after surgery, on the Lysholm knee scoring scale (<jats:italic>P<\/jats:italic> = 0.003, odds ratio = 1.7), as well as on KOOS<jats:sub>Sports\/recreation<\/jats:sub> (<jats:italic>P<\/jats:italic> = 0.002, odds ratio = 1.6) and knee\u2010related quality of life (KOOS<jats:sub>Qol<\/jats:sub>) (<jats:italic>P<\/jats:italic> = 0.037, odds ratio = 1.4), when adjusted for age, gender and Tegner<jats:sub>Pre\u2010injury<\/jats:sub>. The pre\u2010operative K\u2010SES<jats:sub>Future<\/jats:sub> was also a significant predictor (<jats:italic>P<\/jats:italic> = 0.04) of an acceptable outcome 1 year after surgery, on the one\u2010leg hop for distance (odds ratio = 2.2), when adjusted for age, gender and Tegner<jats:sub>Pre\u2010injury<\/jats:sub>. In conclusion, this study indicates that patients\u2019 perceived self\u2010efficacy of knee function pre\u2010operatively is of predictive value for their return to acceptable levels of physical activity, symptoms and muscle function 1 year after ACL reconstruction.<\/jats:p>","DOI":"10.1007\/s00167-007-0433-6","type":"journal-article","created":{"date-parts":[[2007,11,22]],"date-time":"2007-11-22T05:03:29Z","timestamp":1195707809000},"page":"118-127","source":"Crossref","is-referenced-by-count":182,"title":["Self\u2010efficacy of knee function as a pre\u2010operative predictor of outcome 1 year after anterior cruciate ligament reconstruction"],"prefix":"10.1002","volume":"16","author":[{"given":"Pia","family":"Thome\u00e9","sequence":"first","affiliation":[{"name":"Department of Orthopaedics Sahlgrenska Academy G\u00f6teborg University G\u00f6teborg Sweden"},{"name":"Sportrehab \u2013 Physical Therapy and Sports Medicine Clinic G\u00f6teborg Sweden"},{"name":"Lundberg Laboratory for Orthopaedic Research Sahlgrenska University Hospital Gr\u00f6na Str\u00e5ket 12 413 45 G\u00f6teborg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"W\u00e4hrborg","sequence":"additional","affiliation":[{"name":"Department of Molecular and Clinical Medicine Sahlgrenska Academy G\u00f6teborg University G\u00f6teborg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mats","family":"B\u00f6rjesson","sequence":"additional","affiliation":[{"name":"Department of Medicine Multidisciplinary Pain Centre Sahlgrenska University Hospital G\u00f6teborg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roland","family":"Thome\u00e9","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Sahlgrenska Academy G\u00f6teborg University G\u00f6teborg Sweden"},{"name":"Sportrehab \u2013 Physical Therapy and Sports Medicine Clinic G\u00f6teborg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.
