The first 38 consecutive patients (group A) were postoperatively treated with continuous passive motion (CPM), and the next 19 consecutive patients (group B) were treated with active motion for the first 5\u00a0days postoperatively. In both groups, the initial regimens were followed by active motion, slowly progressive strength training, and slowly progressive weight bearing. In group A, after a mean follow\u2010up of 51\u00a0months (range 33\u201392\u00a0months), 29 patients (76%) were graded as excellent or good, 7 patients (19%) were graded as fair, and 2 patients (5%) were graded as poor. In group B, after a mean follow\u2010up of 21\u00a0months (range 14\u201328\u00a0months), 10 patients (53%) were graded as excellent or good, 6 patients (32%) were graded as fair, and 3 patients (15%) were graded as poor. Altogether, nine of the fair or poor cases (50%) were diagnosed with chondromalacia of the patella. Our results, after performing autologous periosteal transplantation in patients with full\u2010thickness cartilage defects of the patella and disabling knee pain, are good if CPM is used postoperatively. The clinical results using active motion postoperatively are not acceptable, especially not in patients with chondromalacia of the patella.<\/jats:p>","DOI":"10.1007\/s001670050154","type":"journal-article","created":{"date-parts":[[2002,8,25]],"date-time":"2002-08-25T03:30:30Z","timestamp":1030246230000},"page":"232-238","source":"Crossref","is-referenced-by-count":68,"title":["Superior results with continuous passive motion compared to active motion after periosteal transplantation"],"prefix":"10.1002","volume":"7","author":[{"given":"H\u00e5kan","family":"Alfredson","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Sports Medicine Unit Department of Orthopaedics University Hospital of Ume\u00e5 S\u201090185 Ume\u00e5 Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronny","family":"Lorentzon","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Sports Medicine Unit Department of Orthopaedics University Hospital of Ume\u00e5 S\u201090185 Ume\u00e5 Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[1999,7]]},"container-title":["Knee Surgery, Sports Traumatology, Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s001670050154.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/article\/10.1007\/s001670050154\/fulltext.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1007\/s001670050154","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T12:44:37Z","timestamp":1760877877000},"score":1,"resource":{"primary":{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/10.1007\/s001670050154"}},"subtitle":["A retrospective study of human patella cartilage defect treatment"],"short-title":[],"issued":{"date-parts":[[1999,7]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1999,7]]}},"alternative-id":["10.1007\/s001670050154"],"URL":"https:\/\/doi.org\/10.1007\/s001670050154","archive":["Portico"],"relation":{},"ISSN":["0942-2056","1433-7347"],"issn-type":[{"value":"0942-2056","type":"print"},{"value":"1433-7347","type":"electronic"}],"subject":[],"published":{"date-parts":[[1999,7]]}}}
