Purpose:
The best approach for treating posterolateral tibial plateau fractures remains controversial. The clinical results of an extended anterolateral approach on such fractures are discussed in this study.
Methods:
Between 2010 and 2011, ten patients with posterolateral tibial plateau fracture were treated using an extended anterolateral approach with a proximal tibial locking compression plate. The epidemiological data, operation details, and clinical outcomes over 26.4 ± 2.3 months (range 24-30 months) of follow-up were prospectively collected and analyzed.
Results:
The average surgical duration was 91.5 ± 18.7 min (range 80-130 min). An anatomic reduction rate of 90 % (9/10) was observed although one patient with a lateral comminuted fracture and dislocation presented a 2-mm joint surface depression postoperatively. The average fracture healing time was 10.6 ± 1.8 weeks (range 8-14 weeks), with an average hospital for special surgery knee score of 95.3 ± 6.5 points (range 80-100 points), an average knee flexion of 119.8° ± 17.2° (range 95°-140°) and an average knee extension of 2.1° ± 2.1° (range 0°-6°). No complications were found.
Conclusions:
The extended anterolateral approach with a proximal tibial compression plate offers direct and complete surgical exposure and may provide an effective method for the surgical treatment of posterolateral tibial plateau fractures.
Level Of Evidence:
Therapeutic, Level IV.
