The visualization portals were made high in the soft spot above the level of the lower pole of the patella. Patients were treated by resection of the affected part of the fat pad and assessed via the Lysholm knee and Tegner activity level scales preoperatively and at 3 months and at 1 year postoperatively, as well as at the conclusion of this study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean age of the patients was 38 years (range, 19 to 62 years). The mean duration of symptoms before surgery was 10 months (range, 1 to 22 months). Twelve patients had one or more previous failed arthroscopies at other centers. The mean follow\u2010up period was 68 months (range, 49 to 95 months). The mean improvement in Lysholm score was 44.76, 55.58, and 53.97 at 3 months, at 1 year, and at the latest follow\u2010up, respectively. On the basis of the Tegner activity level, all but 4 patients returned to their preinjury status. A statistically significant negative correlation was found between duration of symptoms and gain in Lysholm score after surgery (Pearson\n                      <jats:italic>r<\/jats:italic>\n                      = \u22120.58). Three types of lesion were identified. After resection, patients with acute lesions (type 1) had a quicker return to their previous level of activity according to the Tegner scale as compared with patients with chronic lesions (types 2 and 3) (\n                      <jats:italic>P<\/jats:italic>\n                      = .05 and .03, respectively).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Patients with Hoffa's disease without any other concomitant pathology can expect resolution or long\u2010term improvement in their symptoms and function after arthroscopic resection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Level IV, therapeutic case series.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2007.05.013","type":"journal-article","created":{"date-parts":[[2007,12,1]],"date-time":"2007-12-01T01:14:04Z","timestamp":1196471644000},"page":"1180","source":"Crossref","is-referenced-by-count":61,"title":["Impingement of Infrapatellar Fat Pad (Hoffa's Disease): Results of High\u2010Portal Arthroscopic Resection"],"prefix":"10.1002","volume":"23","author":[{"given":"Deepak","family":"Kumar","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedics Morriston Hospital Swansea Wales"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abtin","family":"Alvand","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedics Wexham Park Hospital Slough England"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.P.","family":"Beacon","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedics West Hertfordshire NHS Trust Hertfordshire England"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,11,1]]},"reference":[{"key":"e_1_2_3_2_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1904.92500120002h"},{"key":"e_1_2_3_3_1","first-page":"371","article-title":"Lesions of the infrapatellar fat pad and synovial fringes: Hoffa's disease","volume":"33","author":"Smilie I.S.","year":"1963","journal-title":"Acta Orthop Scand"},{"key":"e_1_2_3_4_1","first-page":"586","article-title":"Hoffa's disease;
