In this prospective randomized clinical trial, the study hypothesis was that the hamstring tendons are equally good graft material as the patellar tendon in ACL reconstruction. Ninety\u2010nine patients with laxity due to a torn ACL underwent arthroscopically assisted reconstruction with graft randomization according to their birth year to either patellar tendon with metal interference screw fixation or double looped semitendinosus and gracilis tendons with fixation similar to the Endobutton technique using a titanium metal plate suspension proximally and screw\u2010washer postdistally. Excluding preoperative Lysholm knee score, there were no significant differences between the two groups in the preoperative and operative data. A standard rehabilitation regimen was used for all the patients, including immediate postoperative mobilization without a knee brace, protected weight bearing for 2 weeks, and return to full activity at 6\u201312\u00a0months postoperatively. Forty patients in the patellar tendon group and 39 patients in the hamstring tendon group were available for clinical evaluation at median 5 years after surgery (ranges 3 years 11\u00a0months\u20136 years 7\u00a0months). The results revealed no statistically significant differences with respect to clinical and instrumented laxity testing, isokinetic muscle torque measurements, International Knee Documentation Committee ratings, Lysholm (knee score), Tegner (activity level) and Kujala patellofemoral knee scores. There was an enlargement of the drill tunnels, statistically more in the hamstring tendon group, but no increase from 2 to 5 years in either group. Narrowing of the joint spaces (IKDC measurement method) from 2 to 5 years postoperatively was seen in both the groups, however, without difference between the two groups.<\/jats:p>","DOI":"10.1007\/s00167-006-0059-0","type":"journal-article","created":{"date-parts":[[2006,3,21]],"date-time":"2006-03-21T05:59:11Z","timestamp":1142920751000},"page":"517-528","source":"Crossref","is-referenced-by-count":75,"title":["Randomized prospective study of ACL reconstruction with interference screw fixation in patellar tendon autografts versus femoral metal plate suspension and tibial post fixation in hamstring tendon autografts: 5\u2010year clinical and radiological follow\u2010up results"],"prefix":"10.1002","volume":"14","author":[{"given":"Arsi","family":"Harilainen","sequence":"first","affiliation":[{"name":"ORTON Orthopaedic Hospital Invalid Foundation Tenholantie 10 00280 Helsinki Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Linko","sequence":"additional","affiliation":[{"name":"Deaconess Hospital Diacor Alppikatu 2 00530 Helsinki Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jerker","family":"Sandelin","sequence":"additional","affiliation":[{"name":"ORTON Orthopaedic Hospital Invalid Foundation Tenholantie 10 00280 Helsinki Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,3,22]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199303000-00025"},{"key":"e_1_2_6_3_1","first-page":"57","article-title":"A comparison between patellar tendon and doubled semitendinosus\/gracilis tendon for anterior cruciate ligament reconstruction","volume":"19","author":"Aglietti P","year":"1997","journal-title":"A minimum five\u2010year follow\u2010up.
