Functional knee phenotypes: a novel classification for phenotyping the coronal lower limb alignment based on the native alignment in young non-osteoarthritic …

MT Hirschmann, LB Moser, F Amsler… - Knee Surgery, Sports …, 2019 - Springer
Purpose The currently used system to classify the lower limb alignment (neutral, varus,
valgus) does not consider the orientation of the joint line or its relationship to the overall …

Phenotyping the knee in young non-osteoarthritic knees shows a wide distribution of femoral and tibial coronal alignment

MT Hirschmann, LB Moser, F Amsler… - Knee Surgery, Sports …, 2019 - Springer
Purpose There is a lack of knowledge about the joint line orientation of the femur and tibia in
non-osteoarthritic knees. The primary purpose of the present study was to evaluate the …

Phenotyping of hip–knee–ankle angle in young non-osteoarthritic knees provides better understanding of native alignment variability

MT Hirschmann, S Hess, H Behrend, F Amsler… - Knee Surgery, Sports …, 2019 - Springer
Purpose There is a lack of knowledge about the native coronal knee alignment in 3D. The
currently used classification system (neutral, valgus and varus) oversimplifies the coronal …

Coronal plane alignment of the knee (CPAK) classification: a new system for describing knee phenotypes

SJ MacDessi, W Griffiths-Jones, IA Harris… - The bone & joint …, 2021 - boneandjoint.org.uk
Aims A comprehensive classification for coronal lower limb alignment with predictive
capabilities for knee balance would be beneficial in total knee arthroplasty (TKA). This paper …

Osteoarthritic and non‐osteoarthritic patients show comparable coronal knee joint line orientations in a cross‐sectional study based on 3D reconstructed CT images

S Hess, LB Moser, EL Robertson… - Knee Surgery …, 2022 - Wiley Online Library
Purpose Recently introduced total knee arthroplasty (TKA) alignment strategies aim to
restore the pre‐arthritic alignment of an individual patient. The native alignment of a patient …

Mechanical alignment for primary TKA may change both knee phenotype and joint line obliquity without influencing clinical outcomes: a study comparing restored and …

E Sappey‐Marinier, C Batailler, J Swan… - Knee Surgery …, 2022 - Wiley Online Library
Purpose In total knee arthroplasty (TKA), knee phenotypes including joint line obliquity are
of interest regarding surgical realignment strategies. The hypothesis of this study is that …

Mismatch between femur and tibia coronal alignment in the knee joint: classification of five lower limb types according to femoral and tibial mechanical alignment

YH Lin, FS Chang, KH Chen, KC Huang… - BMC musculoskeletal …, 2018 - Springer
Background Reasons for dissatisfaction with total knee arthroplasty (TKA) include unequal
flexion or extension gap, soft tissue imbalance, and patella maltracking, which often occur …

Functional knee phenotypes of OA patients undergoing total knee arthroplasty are significantly more varus or valgus than in a non-OA control group

JY Jenny, F Baldairon, MT Hirschmann - Knee Surgery, Sports …, 2022 - Springer
Purpose The aim of this study was to analyse the coronal alignment of a large population of
patients undergoing total knee arthroplasty using a modern classification of the knee …

Gender-specific distribution of knee morphology according to CPAK and functional phenotype classification: analysis of 8739 osteoarthritic knees prior to total knee …

S Huber, JA Mitterer, SM Vallant, S Simon… - Knee Surgery, Sports …, 2023 - Springer
Purpose Osteoarthritis of the knee is commonly associated with malalignment of the lower
limb. Recent classifications, as the Coronal Plane Alignment of the Knee (CPAK) and …

Neutral alignment leads to higher knee society scores after total knee arthroplasty in preoperatively non-varus patients: a prospective clinical study using 3D-CT

O Slevin, A Hirschmann, FF Schiapparelli… - Knee Surgery, Sports …, 2018 - Springer
Purpose The optimal coronal alignment is still under debate. However, in most of the
studies, alignment was only assessed using radiographs, which are not accurate enough for …
