Comparative Outcomes of Single- Versus Dual-Incision Approaches for Open Reduction and Internal Fixation of Complex Tibial Plateau Fractures.

Background/

Objectives

Open reduction and internal fixation with plates and screws is the treatment of choice for bicondylar tibial plateau fractures. The use of a surgical approach remains a topic of debate regarding the site and number of incisions that ensure best access for reduction with minimum additional soft tissue damage. This retrospective cohort study compared clinical, radiological, and functional outcomes of single- (anterior) versus dual-incision (anterolateral and medial) approaches that are widely used in the operative treatment of Schatzker V-VI tibial plateau fractures.

Methods

Eighty-two patients treated between 2005 and 2020 were retrospectively analyzed. Fifty-two underwent a single-incision (SI) approach and 30 a dual-incision (DI) approach. Operative parameters, complications, reduction quality, Knee Society Score (KSS), Oxford Knee Score (OKS), and post-traumatic arthritis incidence were assessed.

Results

Mean patient age was 50.6 years, with a mean follow-up of 8.5 years. Operative time was shorter in the SI group, though fluoroscopy time was longer. No significant difference was observed in reduction quality or wound complications. Post-traumatic arthritis occurred in 57.6% of SI and 53.3% of DI patients, with severe arthritis more frequent in SI (30% vs. 12.5%, p < 0.05). Seven patients required conversion to total knee arthroplasty (five SI, two DI). Functional recovery was similar: mean KSS 68.6% (SI) vs. 70.5% (DI) and OKS 36.1 vs. 40.8 (p > 0.05) at 5 years.

Conclusions

Both single- and dual-incision approaches for complex tibial plateau fractures provide satisfactory long-term outcomes. While differences in complications and arthritis rates were minor, surgical choice should be guided by the fracture morphology, patient characteristics, and surgeon's experience to balance reduction quality with soft tissue preservation.
