Kinematic alignment in Japanese patients shows significant improvement 2 years after total knee replacement surgery [PDF]

Journal of Experimental Orthopaedics
Purpose This study aimed to evaluate the 2‐year post‐operative results of the unrestricted kinematic alignment technique in total knee arthroplasty (TKA) among Japanese patients and understand the potential benefits of this technique.

The kinematic alignment technique for TKA reliably aligns the femoral component with the cylindrical axis

Orthopaedics & Traumatology: Surgery & Research, 2017
Kinematic alignment (KA) technique is an alternative technique for positioning a TKA, which aims a patient-specific implant positioning in order to reproduce the pre-arthritic knee anatomy. Because reliability in implant positioning is of interest to obtain reproducible good functional results, our study tests the hypothesis that the medial and lateral

Alignment techniques in total knee arthroplasty

Journal of Joint Surgery and Research, 2023
Purpose: Total knee arthroplasty (TKA) reduces knee pain to improve knee function for painful knee osteoarthritis and provides excellent long-term survivorship. However, approximately 20% of patients remain dissatisfied.

Restoration of Joint Inclination in Total Knee Arthroplasty Offers Little Improvement in Joint Kinematics in Neutrally Aligned Extremities

Frontiers in Bioengineering and Biotechnology, 2021
Kinematically aligned total knee replacements have been shown to better restore physiological kinematics than mechanical alignment and also offer good postoperative satisfaction.

Kinematic alignment in total knee arthroplasty restores the native anatomy, with a joint line parallel to the ground on a standing view. [PDF]

J Orthop
Kinematic alignment (KA) total knee arthroplasty (TKA) restores the native alignment of the knee joint. The present study compared the pre-and post-operative limb alignment of patients undergoing KA-TKA.

La alineación de la artroplastia de rodilla. Antiguos mitos y nuevas controversias

Revista Española de Cirugía Ortopédica y Traumatología, 2021
Resumen: Existe controversia en cuanto a la mejor técnica de alineación en las artroplastias de rodilla. La alineación mecánica persigue mantener el eje de la extremidad en 180 ± 3°, y para ello utiliza la instrumentación estándar y las liberaciones ...

Current concepts in total knee arthroplasty: mechanical, kinematic, anatomical, and functional alignment

Bone & Joint Open, 2021
Limb alignment in total knee arthroplasty (TKA) influences periarticular soft-tissue tension, biomechanics through knee flexion, and implant survival. Despite this, there is no uniform consensus on the optimal alignment technique for TKA.

Postoperative clinical outcomes for kinematically, restricted kinematically, or mechanically aligned total knee arthroplasty: a systematic review and network meta-analysis of randomized controlled trials

BMC Musculoskeletal Disorders, 2023
Background Mechanically aligned total knee arthroplasty (MATKA) is a well-established procedure. Kinematically aligned TKA (KATKA) has been proposed to restore and preserve pre-arthritic knee anatomy. However, normal knee anatomy varies widely, and there

Personalized alignment™ for total knee arthroplasty using the ROSA® Knee and Persona® knee systems: Surgical technique

Frontiers in Surgery, 2023
Total knee arthroplasty (TKA) procedures are expected to increase up to 565% in the United States over the next 3 decades. TKAs were traditionally performed with neutral mechanical alignments that provided equal medial and lateral gaps in extension and ...
