Objective

2

To explore the clinical effect of internal fixation via knee anterior median approach in the treatment of type C2C3 fractures of distal femur.

Methods

2

A total of 11 patients with comminuted fracture of distal femur in Affiliated Hospital of Zunyi Medical University from April 2019 to April 2021 were selected as the study objects， of which 6 patients were treated with double plate internal fixation via knee anterior median approach as the observation group， and 5 patients were treated with double plate internal fixation via internal and external incisions approach as the control group. The exposure degree of articular surface of femoral condyle， operation time， intraoperative blood loss， postoperative drainage volume and postoperative knee joint function were compared between the two groups. The effect of internal fixation via knee anterior median approach for type C2C3 fractures of distal femur was evaluated.

Results

2

The articular surface of femoral condyle can be exposed satisfactorily through the knee anterior median approach. The operation time and intraoperative blood loss of the observation group were less/shorter than those of the control group （

P

<

0.05）， and there was no significant difference in postoperative drainage volume and knee function scores between the two groups （

P

>

0.05） .

Conclusion

2

The treatment of type C2C3 fractures of distal femur by internal fixation via knee anterior median approach has good effect with the advantages of full exposure， shorter operation time and less bleeding.
