Incidence of postoperative complications

  1. aDue to heterogeneity in the reporting of outcomes observed we groups our findings into five categories: operative/ischaemic time (n = 11), accuracy (n = 16), incidence of postoperative complications (n = 5), assessment of aesthetic outcome (n = 3) and cost (n = 5)
  2. bAccuracy itself was also very heterogenous, based on our findings we further categorised this into three categories: bone harvested vs. bone used (n = 4), postoperative bilateral measurements (n = 5) and comparison between pre- and postoperative CT scans (n = 7)
