In ten uninjured knees with known hyperextension, the knees were bandaged in the same way as after an ACL\u2010reconstruction. The knees were then studied radiologically in a Hypex brace set at 0\u00b0, \u22125\u00b0 and \u221210\u00b0 of knee extension. Not a single knee was found to be straight in the brace set at 0\u00b0. At \u22125\u00b0 most of the knees were straight or in slight hyperextension. It took \u221210\u00b0 to get all knees straight or in hyperextension. In a prospective randomised study 44 patients who underwent an arthroscopic ACL\u2010reconstruction with a bone patellar tendon bone graft were randomised to use either a brace set at \u22125\u00b0 or a straight brace (0\u00b0) for at least the first three postoperative weeks. Before and three months after surgery range of motion was determined, using a goniometer with long arms, and sagittal knee laxity was measured with a KT\u20102000 arthrometer at manual max. Pre\u2010 and post\u2010operative pain was evaluated with the Visual Analogue Scale (VAS). The same examiner (blindfolded to what type of brace was used) performed all the measurements. At three months, two of the 22 patients with the brace set at \u22125\u00b0 and twelve of the 22 patients with the straight brace had a loss of full extension of 2\u00b0 or more (<jats:italic>p<\/jats:italic>&lt;0.001). No significant differences were found between the groups in terms of knee flexion, sagittal knee laxity or post\u2010operative pain. Although extension deficit after ACL\u2010reconstruction can be prevented also in other ways, a Hypex brace set at \u22125\u00b0 seems to be an easy way of ensuring full knee extension.<\/jats:p>","DOI":"10.1007\/s00167-003-0406-3","type":"journal-article","created":{"date-parts":[[2004,3,18]],"date-time":"2004-03-18T21:45:18Z","timestamp":1079646318000},"page":"318-321","source":"Crossref","is-referenced-by-count":28,"title":["Can
