Abstract

The purpose of the current study was to evaluate the functional outcome of bicondylar tibial plateau fractures treated by open reduction and internal fixation utilising: Rasmussen's functional grading system and Rasmussen's radiological grading system. Both of these grading systems were developed by Rasmussen. Methods: The GIMSR Department of Orthopaedics at Visakhapatnam, Andhra Pradesh, conducted a prospective observational study from August 2021 to January 2023. Surveyed were orthopaedic patients with bicondylar tibial plateau fractures. Tibial Plateau fractures were most common in adults, especially urbanites. Thirty bicondylar tibial plateau fractures needed correction. A sample size of 26 is needed to obtain 80% power and 95% accuracy if % of participants have a certain functional outcome. 30 participants were used to adjust for dropouts. Result: For evaluating each individual who took part in the research project, Rasmussen's functional and radiological grading systems, which he had devised, were applied. Both of the grading methods had a strong correlation (r = 0.888) not only with one another but also with the overall result. Conclusion: Open reduction and internal fixation of bicondylar tibial plateau fractures will restore articular congruity, enable early motion, minimise post-traumatic OA, and optimise knee function. Regardless of velocity and initial comminution, careful articular reduction and waiting for soft tissue healing yield good functional results. The locking compression plate is stable for tibial plateau fractures, and the locking screw held well even in osteoporotic bones. Malalignment and instability affect function more than joint surface deformity.
