Objectives:
The goal of this study is to determine the efficacy of the surgical treatment of lateral Hoffa fracture with a locking plate and cannulated or lag screws through the lateral approach.
Materials And Methods:
A total of 12 isolated lateral Hoffa fractures were identified during the study period (February 2005 to February 2010). All fractures were treated by open reduction through the lateral approach. Internal fixation was performed with a contoured locking plate and cannulated or lag screws introduced from the non-weight-bearing area of the cartilage surface of the lateral femoral condyle. Radiological and functional outcome analysis was performed using Knee Society scores.
Results:
Bony union of Hoffa fracture was achieved in all patients. The articular surface of lateral femoral condyle was anatomically reduced. There was no loss of reduction and fixation. Functional outcome of knee measurements showed a continuous significant improvement over the follow-up period.
Conclusion:
Fixation with a locking plate and cannulated or lag screws for lateral Hoffa fracture seemed to be effective and reliable. The lateral approach had advantages for reduction and fixation of lateral Hoffa fracture during operation.
