Our confidence in the evidence is limited. Although pooled evidence indicated that surgical treatment may lead to improved functional outcome but with an increased risk of unplanned second operations, we judged the evidence to be of low certainty as it was often derived from few participants in studies that were not sufficiently robust in design. We found no evidence of a difference between treatment options in the number of people who needed late reconstruction surgery for subtalar arthritis, although the estimate included the possibility of important harms and benefits. Large, well-conducted studies that attempt to minimise detection bias and that measure functional outcomes using calcaneal-specific measurement tools would increase the confidence in these findings. Given that minimally invasive surgical procedures are already becoming more prevalent in practice, research is urgently needed to determine whether these newer surgical techniques offer better outcomes with regard to function, pain, quality of life, and postoperative complications for intra-articular displaced calcaneal fractures.
