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

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.
