Abstract: Background: Tibial plateau is important component of knee joint and bicondylar fracture of tibial plateau is a complex fracture and challenges to orthopaedic surgeon. The lateral locking plate alone may not be sufficient to hold this fragment, because of the morphology and position of postero-medial fragment, leading to late varus collapse. To counter this problem, a separate posteromedial buttress plateis now been used by surgeons.
Method: This is a prospective study that included 36 patients with closed posteromedial tibial plateau fractures who had undergone open reduction and internal fixation through a posteromedial approach by plate and screws between August 2017 and December 2020. Open reduction was done for all patients with anterolateral and open posteromedial approach internal fixation was done with lateral and posteromedial buttress plate.
Result: As per Rasmussen’s functional scoring 26(72.23%) patients have excellent outcome, in 8 (22.23%) patients and in two patients (5.56%) outcome was fair.
Discussion and Conclusion: Bicondylar fracture is more common in younger population with female predominance. Road traffic accident is more common than then fall and schatzker type 5 fracture was common than schatzker type 6 fracture. Rasmussen’s functional scoring patients have excellent in more than 70 % patients. Posteromedial buttress plate is a good tool for management of bicondylar fracture of tibia.
