This article discusses the diagnosis of instability after a total knee replacement or arthroplasty. The surgeon needs to gather all information about the reason for the replacement, the medical history of the patient, the post-operative techniques after the replacement, rehabilitation, and a description of the type of prosthesis used. There are three types of instability that can be identified after a total knee replacement: extension instability, flexion instability, and genu recurvatum. Extension instability is usually the result of excessive bone removal from the distal part of the femur and can be corrected by using a thicker tibial insert.

    Background: Using patient-specific cutting blocks for TKA increases the cost to the hospital for these procedures, but it has been proposed they may reduce operative times and improve implant alignment, which could reduce the need for revision surgery. Questions/purposes: We compared TKAs...

    Background: Mobile-bearing TKAs reportedly have no clinical superiority over fixed-bearing TKAs, but a potential benefit is improved polyethylene wear behavior.
