Functional And Radiological Outcomes Ofm IntraArticular Lateral Tibial Condyle Fractures Treated Via The Submeniscal Approach: A Prospective Observational Study

Abstract

Background: Lateral tibial condyle fractures pose a challenge due to their involvement of the articular surface and associated soft tissue structures. The submeniscal approach provides direct visualization for anatomical reduction while minimizing soft tissue disruption.

Objective: To evaluate the functional and radiological outcomes of intra-articular lateral tibial condyle fractures treated with open reduction and internal fixation (ORIF) via the submeniscal approach.

Methods: In a prospective study conducted at Dr. D.Y. Patil Medical College, 30 patients aged 18–60 years with Schatzker type I–VI tibial plateau fractures were treated with ORIF using a lateral locking plate through the submeniscal approach. Functional outcomes were assessed using the Knee Society Score (KSS), Lysholm Score, and KOOS at 3 months. Radiological union and complications were monitored up to 9 months postoperatively.

Results: At 3 months, 86.66% of patients achieved KSS scores ≥85, indicating good to excellent functional outcomes. Radiological union was observed in 83.33% by 6 months. The complication rate was 26.67%, with delayed union being the most common. No significant associations were found between functional scores and demographic or fracture characteristics. A strong correlation was observed between early functional scores and 3-month outcomes.

Conclusion: The submeniscal approach offers a reliable and effective technique for the fixation of lateral tibial condyle fractures, facilitating anatomical reduction, early mobilization, and favorable functional outcomes with a low complication profile.
