Variations in medial and lateral slope and medial proximal tibial angle [PDF]

Knee Surgery, Sports Traumatology, Arthroscopy, 2020
AbstractPurposeThe primary objective of this study was to quantify the variations of the medial posterior tibial slope (MPTS) and the lateral posterior tibial slope (LPTS), as well as of the medial proximal tibial angle (MPTA), and to determine the fraction of patients for which standard techniques including different alignment techniques would result ...

Postoperative Medial Tilting of the Joint Line and Preoperative Kinematics Influence Postoperative Medial Pivot Pattern Reproduction in Total Knee Arthroplasty

Arthroplasty Today, 2023
Background: Reproducing the medial pivot pattern after total knee arthroplasty (TKA) is known to improve patient satisfaction. However, the factors affecting the postoperative medial pivot pattern in TKA are controversial.

Medial proximal tibial angle after medial opening wedge HTO: A retrospective diagnostic test study

Indian Journal of Orthopaedics, 2012
Medial proximal tibial angle (MPTA) is the commonly used angle, which is simply measured from the knee radiographs. It can determine the correction angle in medial opening wedge high tibial osteotomy (MOWHTO). The hypothesis of our study is that post-osteotomy MPTA can predict the change in correction angle, and we aimed to determine the optimal MPTA ...

Tibial morphological variations reveal medial proximal tibial angle discrepancies in Japanese patients: Three‐type classification for high tibial osteotomy

Journal of Experimental Orthopaedics
Purpose This study aimed to characterize the tibial morphology among Japanese patients with varus knee osteoarthritis and examine whether the mechanical and proximal anatomical medial proximal tibial angles (mMPTA and paMPTA) are equivalent in high ...

Comparable medial proximal tibial angle measurements on full-leg standing radiographs and the Rosenberg view in patients undergoing high tibial osteotomy

Journal of ISAKOS
Medial open wedge high tibial osteotomy (MOW-HTO) is a standard treatment for medial compartment osteoarthritis (OA) of the knee. Its success relies on precise preoperative planning, typically using full-leg standing radiographs (FLSR) for coronal alignment assessment. However, factors like knee flexion and rotation can influence alignment measurements.

A posterior tibial slope angle over 12 degrees is critical to epiphyseal fracture of the proximal tibia: Three-dimensional finite element analysis

Heliyon, 2023
Introduction: The effects of the proximal tibial slope angle on the proximal tibial epiphysis remain unknown. To elucidate those effects, we investigated the strain distribution in proximal tibial epiphysis with different proximal tibial slope angles and

Iatrogenic ischiofemoral impingement due to high tibial osteotomy with overvalgization: a case report

Journal of Medical Case Reports, 2022
Background Open wedge high tibial osteotomy is a standard procedure for frontal realignment. It is indicated in varus knee with reduced mechanical medial proximal tibia angle.

Relationship between lower limb torsion and coronal morphologies of the femur and tibia in patients with medial knee osteoarthritis

BMC Musculoskeletal Disorders, 2020
Background To investigate the relationship between femoral or tibial torsion and hip-knee-ankle angle (HKA), mechanical lateral distal femoral angle (mLDFA), or mechanical medial proximal tibial angle (mMPTA) in patients with medial knee osteoarthritis ...

Anatomical Imaging Study on Uneven Settlement of the Proximal Tibia

Orthopaedic Surgery, 2023
Objective Uneven settlement of the proximal tibia significantly contributes to the onset and progression of medial compartment knee OA; however, the specific location and variations of proximal tibial deformity remain unclear. Therefore, this study aimed
