Knee Joint Line Obliquity Causes Tibiofemoral Subluxation That Alters Contact Areas and Meniscal Loading [PDF]

American Journal of Sports Medicine, 2021
Background: Little scientific evidence is available regarding the effect of knee joint line obliquity (JLO) before and after coronal realignment osteotomy. Hypotheses: Higher JLO would lead to abnormal relative position of the femur on

Assessment of joint line obliquity and its related frontal deformity using long-standing radiographs [PDF]

Journal of Orthopaedics, 2023
To investigate how radiographic techniques and osteoarthritis grade influence measurements of knee joint line obliquity (KJLO) and KJLO-related frontal deformity, and to propose preferable KJLO measurement methods.Forty patients with symptomatic medial knee osteoarthritis indicated for high tibial osteotomy were assessed.

The actual knee function was not influenced by joint line obliquity after open-wedge high tibial osteotomy [PDF]

SICOT-J, 2020
Purpose: Excessive joint line obliquity (JLO) after open-wedge high tibial osteotomy (OWHTO) induces detrimental stress on the articular cartilage. The purpose of this article is to assess the correlation between JLO and the clinical results after OWHTO.

Using the Lower Limb Adduction Angle to Predict Postoperative Knee Joint-Line Obliquity After Open-Wedge High Tibial Osteotomy [PDF]

Orthopaedic Journal of Sports Medicine, 2021
Background: Knee joint-line orientation is altered after open-wedge high tibial osteotomy (OWHTO), and excessive joint-line obliquity (JLO) can adversely affect outcomes.

Medial joint line obliquity and medial meniscus tear were associated with medial meniscal extrusion: A case–control study [PDF]

Journal of Experimental Orthopaedics
Purpose Medial meniscal extrusion is a key factor in accelerating knee osteoarthritis. Medial joint line obliquity causes increased contact pressure on the medial meniscus, which potentially induces medial meniscal extrusion.

Knee-ankle joint line angle: a significant contributor to high-degree knee joint line obliquity in medial opening wedge high tibial osteotomy [PDF]

Journal of Orthopaedic Surgery and Research, 2022
Background Medial opening wedge high tibial osteotomy (MOWHTO) changes the knee joint inclination in the coronal plane, which can be compensated by the ankle joint.

Analysis of Knee Joint Line Obliquity after High Tibial Osteotomy [PDF]

Journal of Knee Surgery, 2016
The aim of this study was to evaluate which lower extremity alignment (knee and ankle joint) parameters affect knee joint line obliquity (KJLO) in the coronal plane after open wedge high tibial osteotomy (OWHTO). Overall, 69 knees of patients that underwent OWHTO were evaluated using radiographs obtained preoperatively and from 6 weeks to 3 months ...

Association of coronal knee phenotype and joint line obliquity with proximal tibiofibular joint morphology in advanced osteoarthritis

Journal of Orthopaedic Surgery
Purpose The proximal tibiofibular joint (PTFJ) is biomechanically related to the tibiofemoral joint and may influence load transmission across the knee. However, it remains unclear whether PTFJ morphology is associated with coronal knee phenotype, joint ...

Joint-line obliquity angle is significantly affected by hip abduction and adduction: A simulated analysis

Knee Surgery, Sports Traumatology, Arthroscopy
AbstractPurposeDifferent methods for quantifying joint‐line obliquity (JLO) have been described, including joint‐line obliquity angle (JLOA), Mikulicz joint‐line angle (MJLA) and medial proximal tibial angle (MPTA). The goal of the present study was to quantify the variation of JLOA based on the position of the hip.
