articular congruity
The precise anatomical alignment and smooth surface continuity of joint surfaces after fracture repair.
Full Definition
Articular congruity refers to the restoration of normal joint surface anatomy following intra-articular fracture repair. This includes both the geometric alignment of bone fragments and the smoothness of the cartilage surface. Achieving perfect articular congruity is crucial for preventing post-traumatic arthritis and maintaining joint function. Even minimal step-offs or gaps in the joint surface can lead to accelerated cartilage wear and poor long-term outcomes.
Usage
Usage note: Often used with 'restoration of' or 'maintenance of' in surgical contexts.
