The goal of this observational study is to learn about the long-term effects of internal fixation methods in patients with posterior column fractures of tibial plateau according to three column concept. The main question it aims to answer is:

Does the internal fixation of posterior column fractures of tibial plateau according to three column concept has a good radiological and clinical outcomes in follow up for 1 year? Participants already having internal fixation for their posterior column fractures will do X ray in their follow up visit and answer survey questions about their joint pain, ROM for 1 year.

The goal of this observational study is to measure the radiological and clinical long term effects of internal fixation methods in patients with posterior column fractures of tibial plateau according to three column concept by using Rasmussen score
