We report the first clinical and radiological data at a short-term follow-up. Twelve patients underwent AMIC-aided cartilage repair for a patellar lesion. All steps of the procedure were performed arthroscopically, which include the use of an intra-articularly placed retraction plate for distraction of the patellofemoral joint and evacuation of saline solution for collagen matrix insertion and fixation. Clinical assessment performed before surgery and at a mean follow-up time of 38 months (range: 24\u201370) included the following scores: Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC), and visual analog scale (VAS). Magnetic resonance imaging was performed at the follow-up examination, including the magnetic resonance observation of cartilage repair tissue (MOCART) score. The mean KOOS and IKDC scores increased significantly (p\u2009&lt;\u20090.01) from 50.3 and 37.4 points preoperatively to 90.1 and 79.4 postoperatively. The VAS score decreased from 7.8 to 2.3 points. Mean MOCART score at follow-up was 58.3 points. Cartilage repair of patellar lesions aided by a retraction system in a dry arthroscopy setup is a promising approach. Further studies are needed to evaluate this procedure and compare it to existing matrix implantation techniques. The level of evidence for the study is 4 (case series).<\/jats:p>","DOI":"10.1055\/s-0037-1599246","type":"journal-article","created":{"date-parts":[[2017,3,10]],"date-time":"2017-03-10T23:49:43Z","timestamp":1489189783000},"page":"925-929","source":"Crossref","is-referenced-by-count":25,"title":["All-Arthroscopic Autologous Matrix-Induced Chondrogenesis-Aided Repair of a Patellar Cartilage Defect Using Dry Arthroscopy and a Retraction System"],"prefix":"10.1055","volume":"30","author":[{"given":"Mariusz","family":"Puszkarz","sequence":"first","affiliation":[{"name":"Biological Joint Reconstruction Department, St Luke's Hospital, Bielsko-Biala, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lidia","family":"Kosmalska","sequence":"first","affiliation":[{"name":"Biological Joint Reconstruction Department, St Luke's Hospital, Bielsko-Biala, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Wiewiorski","sequence":"first","affiliation":[{"name":"Orthopaedic and Trauma Department, Kantonsspital Winterthur, Winterthur, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boguslaw","family":"Sadlik","sequence":"additional","affiliation":[{"name":"Biological Joint Reconstruction Department, St Luke's Hospital, Bielsko-Biala, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2017,3,10]]},"container-title":["The Journal of Knee Surgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0037-1599246.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,12,19]],"date-time":"2017-12-19T13:48:13Z","timestamp":1513691293000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0037-1599246"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,3,10]]},"references-count":0,"journal-issue":{"issue":"09","published-online":{"date-parts":[[2017,10,25]]},"published-print":{"date-parts":[[2017,11]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0037-1599246","relation":{},"ISSN":["1538-8506","1938-2480"],"issn-type":[{"value":"1538-8506","type":"print"},{"value":"1938-2480","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,3,10]]}}}
