Gait analysis was performed on eight healthy male subjects with the right knee in an orthotic brace locked at 0\u00b0, 10\u00b0, 20\u00b0 and 30\u00b0, with the brace unlocked and also without a brace. The ground reaction force, the angle of the knee and the net external flexion movement about the knee were measured and the extensor mechanism force was calculated. <\/jats:p><jats:p> The results showed a direct non-linear relationship between the angle of knee flexion and the extensor mechanism force. When a brace was applied, the lowest forces occurred when the brace was locked at 0\u00b0. At 30\u00b0 the forces approached the failure strength of some fixation devices. We recommend that for potentially unstable injuries of the extensor mechanism, when mobilising with partial weight-bearing, the knee should be flexed at no more than 10\u00b0. <\/jats:p>","DOI":"10.1302\/0301-620x.89b7.18452","type":"journal-article","created":{"date-parts":[[2007,8,2]],"date-time":"2007-08-02T17:54:42Z","timestamp":1186077282000},"page":"911-914","source":"Crossref","is-referenced-by-count":3,"title":["The relationship of the angle of immobilisation of the knee to the force applied to the extensor mechanism when partially weight-bearing"],"prefix":"10.1302","volume":"89-B","author":[{"given":"W.
