Optimal treatment of patients with patellofemoral trochlear dysplasia and recurrent patellar
instability requires in-depth understanding of this complex structural anomaly. An extensive …

Background: As the main passive structure preventing patellar lateral subluxation, accurate
knowledge of the anatomy, material properties, and functional behavior of the medial …

Kinematic alignment performed with caliper measurements and verification checks
accurately co-align the femoral and tibial components with the 3 axes and joint lines of the …

This article describes the definition, history, and principle of kinematically-aligned total knee
arthroplasty (TKA). The technique and intraoperative checks for kinematic alignment of the …

Background Mechanically aligned (MA) total knee arthroplasty (TKA) is affected by
disappointing functional outcomes in spite of the recent improvements in surgical precision …

Introduction Kinematic (KA) and mechanical (MA) alignment techniques are two different
philosophies of implant positioning that use the same TKA implants. This might generate …

Purpose Complications after total knee arthroplasty (TKA) often involve the patellofemoral
joint, and problems with patellar maltracking or lateral instability have sometimes been …

Objectives Robotic tools have been developed to improve planning, accuracy and outcomes
in total knee arthroplasty (TKA). The purpose of this study was to describe and illustrate a …

Purpose The objective is to evaluate the orientation of the trochlear groove in patients with
objective patellar instability (OPI) compared to a control group. The hypothesis is that the …

Purpose The purposes of this study are to, firstly, develop techniques to accurately identify
extensor mechanism malalignment by measuring the alignment of the quadriceps tendon …
