Instability After Total Knee Replacement: Treatment

Abstract

The authors provide an overview of total knee replacement (TKR) instability causes and discuss how to diagnose these problems in an attempt to help orthopaedic surgeons treat and resolve TKR instability. A thorough workup is essential to provide detailed knowledge of the TKR instability; this enables orthopaedic surgeons to define the nature of the instability and thus develop an appropriate treatment plan. Ligament balancing for primary TKR is discussed in detail because an understanding of the principles is essential for understanding TKR instability. Diagnosis, features, and treatment options for the three main types of TKR instability (flexion-extension instability, flexion instability, and extension instability) are also discussed.
