Distal Femoral Rotation Correlates With Proximal Tibial Joint Line Obliquity: A Consideration for Kinematic Total Knee Arthroplasty

Journal of Arthroplasty, 2018
We hypothesized that there is a correlation between the distal femoral rotation and proximal tibial joint line obliquity in nonarthritic knees. This has significance for kinematic knee arthroplasty, in which the target knee alignment desired approximates the knee before disease.Fifty computed tomography scans of nonarthritic knees were evaluated using ...

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

Knee Surgery, Sports Traumatology, Arthroscopy, 2021
AbstractPurposeIn total knee arthroplasty (TKA), knee phenotypes including joint line obliquity are of interest regarding surgical realignment strategies. The hypothesis of this study is that better clinical results, including decreased postoperative knee pain, will be observed for patients with a restored knee phenotype.MethodsA retrospective analysis

Functional joint line obliquity after kinematic total knee arthroplasty

International Orthopaedics, 2015
Kinematic total knee arthroplasty (TKA) is an emerging technique, but concerns remain around the effect of implanting the prosthesis in more anatomic orientations. Native knees show variation in joint line orientation relative to the tibial mechanical axis but the joint line remains parallel to the floor when standing.

Biomechanical Implications of an Oblique Knee Joint Line

The Journal of Knee Surgery, 2017
AbstractSurgical correction of multiapical deformities of the lower limb requires careful preoperative planning. Surgeons must account for the potential creation of secondary deformity, such as knee joint line obliquity, and the risks associated with accepting these changes in limb alignment.

Changes in ankle and hip joints following medial opening-wedge high tibial osteotomy affect knee joint line obliquity

Knee Surgery, Sports Traumatology, Arthroscopy, 2023
AbstractPurposeThis study aimed to measure the change in knee joint line obliquity (KJLO) and the changes in radiologic parameters of the ankle and hip joints after medial opening‐wedge high tibial osteotomy (MOWHTO), and to evaluate the correlation and causal relationship between these parameters.MethodsThis study evaluated 109 patients who underwent ...

Effect of joint‐line obliquity on long‐term survivorship of total knee arthroplasty: A postoperative phenotype analysis

Knee Surgery, Sports Traumatology, Arthroscopy
AbstractPurposeWhether the longevity of total knee arthroplasty (TKA) differs between postoperative phenotypes has not been investigated. This study aims to examine which phenotype has a worse long‐term survival rate than the reference phenotype (neutral alignment‐parallel joint line), and whether joint‐line obliquity (JLO) affects the survivorship of ...

Knee Joint Line Obliquity With Adaptational Hip and Ankle Joint Orientation After Medial Open Wedge High Tibial Osteotomy

American Journal of Sports Medicine
Background: Time-dependent postoperative changes in knee joint line obliquity (KJLO) and subsequent adaptational changes in the hip and ankle joints have not been fully proven after medial open wedge high tibial osteotomy (MOWHTO). Purpose:

Varus Tibial Joint Line Obliquity

Clinical Orthopaedics and Related Research, 2001
In 60 consecutive total knee arthroplasties done in 52 patients with primary osteoarthritis and varus or neutral tibiofemoral alignment, the posterior condylar angle was calculated intraoperatively and averaged 3.98 degrees (range, 0 degrees-9 degrees).
