A total of 30 patients in group A (13\u00a0male, 17 female, age: 28.7\u00b16.9 years) underwent arthroscopic abrasive arthroplasty. The other patients in group B (<jats:italic>n<\/jats:italic>=17, 11\u00a0male, 8 female, age 26.8\u00b17.0 years) underwent periosteal arthroplasty by an autologous periosteal flap. The maximal diameter of the defects was 31.1\u00b16.7 (range 20\u201345\u00a0mm). The Lysholm score and the intensity of pain were evaluated preoperatively and at the time of follow\u2010up (3.1\u00b11.1, range 2\u20135 years). The Tegner activity score was evaluated before onset of the symptoms and at the time of follow\u2010up. The Lysholm score increased significantly in both groups (in group a from 36.1\u00b17.1 to 42.5\u00b16.6 points and in group B from 42.7\u00b12.4 to 67.6\u00b17.8 points). The result in group B was significantly better than in group A. In group A the intensity of pain was unchanged, whereas patients from group B reported a significant reduction of pain. The level of physical activity (Tegner score) was 5.5\u00b12.1\u00a0in group A and 5.5\u00b12.1\u00a0in group B before onset of the complaints. In follow\u2010up, patients from group B (4.9\u00b11.2) had a reduced Tegner score in tendency. The patients in group A had a significantly reduced level of physical activity (2.7\u00b10.6). A total of 12 patients from group B had a range of motion lesser than 80\u00b0 in flexion. These patients underwent joint mobilization and control arthroscopy. During control arthroscopy there was always found a stable periosteal flap. Short\u2010term clinical results with periosteal arthroplasty produced a significant reduction in pain and improved Lysholm score in comparison to abrasive arthroplasty.<\/jats:p>","DOI":"10.1007\/s00167-004-0579-4","type":"journal-article","created":{"date-parts":[[2005,2,22]],"date-time":"2005-02-22T05:20:03Z","timestamp":1109049603000},"page":"352-356","source":"Crossref","is-referenced-by-count":6,"title":["Operative treatment of deep chondral defects of the patella: results after abrasive arthroplasty and periosteal arthroplasty"],"prefix":"10.1002","volume":"13","author":[{"given":"Gunter","family":"Spahn","sequence":"first","affiliation":[{"name":"Clinic of Traumatology and Orthopaedic Surgery Sophienstrasse 16 99817 Eisenach Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Kirschbaum","sequence":"additional","affiliation":[{"name":"Clinic of Traumatology and Orthopaedic Surgery Sophienstrasse 16 99817 Eisenach Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,2,22]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001670050154"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199004000-00027"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.60B1.627583"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(86)80011-1"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1053\/ar.1999.v15.015014"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004020000217"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001670050100"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001670050046"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354658201000306"},{"key":"e_1_2_6_11_1","first-page":"1","article-title":"Joint debridement.
