Mechanical Versus Restrictive Kinematic Alignment in Robotic-Assisted Total Knee Arthroplasty: A Randomized Controlled Trial [PDF]

Diagnostics
Background: Lower limb malalignment is a hallmark of knee osteoarthritis, with surgical correction techniques evolving from traditional mechanical alignment (MA) to kinematic alignment (KA) approaches.

Conventionally instrumented inverse kinematic alignment for total knee arthroplasty: How is it done?

Journal of Experimental Orthopaedics
Purpose For primary total knee arthroplasty (TKA), there is an increasing trend towards patient‐specific alignment strategies such as kinematic alignment (KA) and inverse kinematic alignment (iKA), which by restoring native joint mechanics may yield ...

Kinematic alignment in total knee arthroplasty [PDF]

EFORT Open Reviews, 2020
Kinematic alignment (KA) is an alternative philosophy for aligning a total knee replacement (TKR) which aims to restore all three kinematic axes of the native knee. Many of the studies on KA have actually described non-KA techniques, which has led to much confusion about what actually fits the definition of KA.

Personalized alignment in total knee arthroplasty: current concepts

SICOT-J, 2021
Traditionally in total knee arthroplasty (TKA), a post-operative neutral alignment was the gold standard. This principle has been contested as functional outcomes were found to be inconsistent.

Restricted kinematic alignment total knee arthroplasty using augmented reality technology to maintain limb alignment within targeted boundaries [PDF]

Arthroplasty
Background An augmented reality (AR)-aided navigation system that utilizes a standard smartphone enables accurate alignment of femoral and tibial components in total knee arthroplasty (TKA) and provides real-time intraoperative quantification of joint ...

Influence of kinematic alignment on femorotibial kinematics in medial stabilized TKA design compared to mechanical alignment [PDF]

Archives of Orthopaedic and Trauma Surgery, 2022
Abstract Introduction Worldwide more and more primary knee replacements are being performed. Kinematic alignment (KA) as one of many methods of surgical alignment has been shown to have a significant impact on kinematics and function.

A geometric and kinematic error model and compensation of a 6-axis motorized optical fiber alignment stage

Advances in Mechanical Engineering, 2015
In order to increase the accuracy of a 6-axis motorized fiber alignment stage, a geometric and kinematic error model was established. A low-order body array was introduced to describe the general topological structure of the alignment stage; a ...

Kinematic alignment versus mechanical alignment in total knee arthroplasty: An up-to-date meta-analysis

Journal of Orthopaedic Surgery, 2022
Purpose The purpose of this meta-analysis was to compare the efficacy and imaging parameters of kinematic alignment (KA) and mechanical alignment (MA) in total knee arthroplasty (TKA) and to evaluate whether patients undergoing KA-TKA benefited more than
