Periarticular fractures around the hip and knee: fix or replace?

The number of periarticular fragility fractures around the hip and knee is increasing. If surgical treatment is indicated, open reduction and internal fixation or replacement can often be viable options. In contrast to secondary replacement, the use of replacement in the acute stage might be advantageous because early rehabilitation and weightbearing can be initiated. This article describes the current literature related to internal fixation or primary replacement in periarticular fractures around the hip and knee.
