Closed reduction compared with open reduction may not be an inferior surgical treatment for patellar fractures as researchers found no significant differences seen between the treatments with regard to outcomes.

Researchers retrospectively reviewed data for 62 patients who underwent surgical treatment of patellar fractures between 2008 and 2013. There were 42 open reductions and 21 closed reductions performed. Fracture healing was assessed with plain radiography.

Results showed the most common fracture type in both groups was a comminuted patellar fracture. Investigators noted tension band wiring was used in the open reduction group and cannulated screw fixation was used in the closed reduction group. The two groups were not significantly different with regard to modified Hospital for Special Surgery score, VAS score for pain and range of motion. The mean time to union was 3.2 months for patients who underwent open reduction and was 3 months for patients who underwent closed reduction. In the open reduction group, there were five cases with postoperative knee stiffness. There were three cases of this in the closed reduction group. A re-fracture was seen in one patient who underwent open reduction. – by Monica Jaramillo
