The authors hypothesized that the combined procedure leads to good long\u2010term outcome in patients with isolated medial knee osteoarthritis (OA) and anterior cruciate ligament (ACL) deficiency.\n<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twenty\u2010three patients with ACL deficiency and concomitant medial knee OA were treated from 2008 to 2016 with a combined UKA (Oxford Partial Knee) and ACLR using a hamstring tendon autograft. The follow\u2010up assessment included VAS pain score, Lysholm score, Oxford Knee Score (OKS), American Knee Society scores (AKSS), International Knee Documentation Committee (IKDC 2000), Tegner and UCLA activity scores. Instrumented laxity test was done using the KT\u20101000 arthrometer. Survivorship analysis was performed using the Kaplan\u2013Meier method. Implant loosening and disease progression was assessed by conventional radiography.\n<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Average follow\u2010up duration was 10 years (6\u201314.5). VAS, Lysholm, Tegner and UCLA scores improved significantly. OKS, AKSS and IKDC 2000 showed excellent results on follow\u2010up. Implant survivorship was 91.4% at 14.5 years. There were 2 revisions with conversion to total knee arthroplasty at 6 and 12 years postoperatively due to trauma and disease progression, respectively. There were no radiological or clinical signs of instability or disease progression in any of the remaining knees. The side\u2010to\u2010side difference using the KT\u20101000 arthrometer was insignificant.\n<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>UKA combined with ACLR is an effective therapeutic option with good outcome and return to sport rate on the long\u2010term.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>IV.\n<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-022-07102-3","type":"journal-article","created":{"date-parts":[[2022,8,25]],"date-time":"2022-08-25T12:03:48Z","timestamp":1661429028000},"page":"1382-1387","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Combined treatment with medial unicompartmental knee arthroplasty and anterior cruciate ligament reconstruction is effective on long\u2010term follow\u2010up"],"prefix":"10.1002","volume":"31","author":[{"given":"Ayham","family":"Jaber","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopedics and Trauma Surgery, Center for Orthopedics, Trauma Surgery and Spinal Cord Injury Heidelberg University Hospital Schlierbacher Landstrasse 200a 69118 Heidelberg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang min","family":"Kim","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Department of Orthopedics and Trauma Surgery GRN\u2010Klinik Schwetzingen Bodelschwinghstra\u00dfe 10 68723 Schwetzingen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Bari\u00e9","sequence":"additional","affiliation":[{"name":"<!--<label>3<\/label>--> Center for Joint Surgery and Sport Injuries, Sportopaedie Heidelberg, Clinic St. Elisabeth Heidelberg Max\u2010Reger\u2010Stra\u00dfe 5\u20107 69121 Heidelberg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcus","family":"Streit","sequence":"additional","affiliation":[{"name":"<!--<label>4<\/label>--> ARCUS Sportklinik Pforzheim Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Holger","family":"Schmitt","sequence":"additional","affiliation":[{"name":"<!--<label>5<\/label>--> Center for Orthopedics and Sports Trauma Surgery Atos Clinic Heidelberg Bismarckstra\u00dfe 9\u201015 69115 Heidelberg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Clarius","sequence":"additional","affiliation":[{"name":"<!--<label>6<\/label>--> Vulpius Klinik GmbH Bad Rappenau Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Merle","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopedics and Trauma Surgery, Center for Orthopedics, Trauma Surgery and Spinal Cord Injury Heidelberg University Hospital Schlierbacher Landstrasse 200a 69118 Heidelberg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yannic","family":"Bangert","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopedics and Trauma Surgery, Center for Orthopedics, Trauma Surgery and Spinal Cord Injury Heidelberg University Hospital Schlierbacher Landstrasse 200a 69118 Heidelberg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,8,25]]},"reference":[{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10194290"},{"key":"e_1_2_10_3_2","first-page":"252","article-title":"Consensus statement on indications and contraindications for medial unicompartmental knee arthroplasty","volume":"24","author":"Berend KR","year":"2015","journal-title":"J Surg Orthop Adv"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0035\u20101040(04)70756\u20104"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2017.03.057"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/0391398819879697"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010011\u20101449\u20105"},{"key":"e_1_2_10_8_2","first-page":"544","article-title":"Rupture of the anterior cruciate ligament: a frequently unrecognized cause of failure of unicompartmental knee prostheses.
