Summary

The purpose of this study is to evaluate and compare implant kinematics of conventional mechanically aligned and anatomically aligned total knee arthroplasties (TKA) at 1 year post-operatively.

Detailed description

Participants will be randomized to receive a primary TKA using either an anatomic alignment or a conventional mechanical alignment technique. Participants will undergo a kinematic analysis of a deep knee bend using single-plane fluoroscopy at 1 year post-operatively. The primary outcome will be based on the 6 degree of freedom kinematics and associated joint component proximity during the knee bend task. Secondary outcomes include the Knee Society Score, the Knee Injury and Osteoarthritis Outcome Score, and the Forgotten Knee Score.

Conditions

• Osteoarthritis, Knee

Interventions

Type	Name	Description
DEVICE	DePuy ATTUNE total knee arthroplasty system	A standard midvastus approach will be used for both alignment technique groups. This is a standard approach for exposing the knee joint for TKA.
