Effect of Anatomic Joint-Line Obliquity Prostheses on Coronal Plane Alignment of the Knee Alignment in a Chinese Population [PDF]

Arthroplasty Today
Background: The Coronal Plane Alignment of the Knee (CPAK) classification describes knee phenotypes based on limb alignment and joint-line obliquity (JLO).

Restoration of Joint Line Obliquity May Not Influence Lower Extremity Peak Frontal Plane Moments During Stair Negotiation [PDF]

Bioengineering
Approximately 15% of total knee arthroplasty (TKA) patients remain dissatisfied after surgery, with joint line obliquity (JLO) potentially affecting patient outcomes.

Radiographic Risk Factors for Excessive Joint Line Obliquity After Knee Osteotomy for Medial Osteoarthritis: A Phenotype-Based Approach [PDF]

Orthopaedic Journal of Sports Medicine
Background: In patients undergoing high tibial osteotomy (HTO), an excessive increase in joint line obliquity (JLO) after surgery leads to poor clinical outcomes.

Kinematic alignment without femoral cartilage‐wear compensation for apex‐distal joint line obliquity: Effects on component alignment [PDF]

Journal of Experimental Orthopaedics
Purpose Pronounced apex‐distal joint line obliquity (JLO) complicates total knee arthroplasty (TKA) by challenging patellofemoral tracking and medial tibial bone support. Joint line obliquity–modified kinematic alignment (JLO‐KA)—a selective modification

An increase in the medial proximal tibial angle of 95° or greater after opening wedge high tibial osteotomy does not necessarily lead to excessive knee joint line obliquity of 5° or greater [PDF]

SICOT-J
Introduction: The relationship between medial proximal tibial angle (MPTA) overcorrection and knee joint line obliquity (KJLO) after opening wedge high tibial osteotomy (OWHTO) remains controversial.

Assessing joint line obliquity in valgus-producing high tibial osteotomy: A scoping review of the literature [PDF]

Journal of Orthopaedics
The variance in knee joint line obliquity (KJLO) measurement methods and radiographic techniques may contribute to the controversy on clinical consequences of KJLO after high tibial osteotomy (HTO).To summarize currently used KJLO measurement methods, including their measurement reliability, and the radiographic techniques used in valgus-producing HTO ...

Lack of evidence for an effect of joint line obliquity after medial opening wedge high tibial osteotomy: A 12‐year single‐centre retrospective study [PDF]

Journal of Experimental Orthopaedics
Purpose Large correction in opening wedge high tibial osteotomy (HTO) may lead to excessive joint line obliquity (JLO). This study hypothesized that the presence of an oblique joint line, defined by knee joint line obliquity (KJLO) > 5° and/or medial ...

Improved clinical outcomes when maintaining a neutral joint line obliquity at high tibial osteotomy and subsequent total knee arthroplasty [PDF]

Journal of Experimental Orthopaedics
Purpose The primary aim was to study the impact of joint line obliquity (JLO) on clinical outcomes and survivorship in patients undergoing total knee arthroplasty (TKA) after a previous high tibial osteotomy (HTO).

The Degree of Joint Line Obliquity Change Is Not Associated with Patient Preference in Bilateral Posterior-Stabilized Total Knee Arthroplasties [PDF]

Journal of Clinical Medicine
Objectives: To evaluate patient reference in paired bilateral posterior stabilized (PS) total knee arthroplasties (TKAs) with significantly different degrees of joint line obliquity (JLO) change. Methods: A retrospective review was conducted on 128 patients who underwent paired bilateral PS TKAs, with greater and smaller JLO changes (G-ΔJLO and S-ΔJLO ...

CT-Based Software-Generated Measurements Permit More Objective Assessments of Arithmetic Hip-Knee-Ankle Axis and Joint Line Obliquity [PDF]

Life
The rapid adoption of robotic-assisted total knee arthroplasty (RATKA) has resulted in pre-operative CT scans becoming more readily available. After the segmentation and identification of landmarks by trained segmentation specialists, the Mako ...
