Secondary aims: to document the average healing time at the dTTO interface, to evaluate frequency of postoperative bone absorption at the distal osteotomy interface, and whether the gap is related to complications of tibia fractures\/delayed unions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Consecutive distal TTO patients were retrospectively reviewed including demographic data and distal gap measurements on intraoperative\/postoperative sagittal knee radiographs. \u2018Gap resorption\u2019 was defined as &gt;2\u2009mm increase in the gap between intraoperative and follow\u2010up radiographs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 101 knees underwent dTTO (2009\u20132015), 73 females\/28 males; mean age(range): age 21 years old (13\u201345). 88% had x\u2010rays that allowed assessment within 4 months. 62% had radiographic healing at the distal OTB\u2010ATS. The initial gap was (mean [range]): 1.48\u2009mm (0\u20138.4). All but two patients had initial gaps &lt;3.3\u2009mm. Eleven per cent had an increase in their distal bony gap\u2009&gt;2\u2009mm (range 2\u20137.8\u2009mm) without radiographic evidence of motion at point of screw fixation. The mean thickness of the OTB as a % of total tibial width was 31% (range 22%\u201337%). There were 4 tibial fractures, none statistically related to initial gap distance, mm of distalization or %thickness of the osteotomy segment. Seven patients had gap resorption &gt;2\u2009mm, 2 with tibia fracture.

At 4 months complete radiographic healing was present in 62%. Bone resorption at the distal OTB\u2010ATS interface is recognised postoperatively (11%).
