Small medial proximal tibial angle is a radiographic finding strongly associated with less coronal alignment correction under valgus stress in medial knee osteoarthritis

Knee Surgery, Sports Traumatology, Arthroscopy
AbstractPurposeThe degree to which varus knees can be corrected manually is important when considering total versus unicompartmental knee arthroplasty (UKA). The primary aim was to clarify the relationship between the degree of coronal alignment correction and radiographic parameters involved in UKA prognosis using preoperative full‐length lower ...

An increased medial proximal tibial angle of greater than 95 degrees after opening wedge high tibial osteotomy is not associated with deterioration of minimum 10-year clinical outcomes

Archives of Orthopaedic and Trauma Surgery
The purpose of this study was to assess whether an excessively increased medial proximal tibial angle (MPTA) resulted in the deterioration of long-term clinical outcomes after opening wedge high tibial osteotomy (OWHTO) for patients with knee osteoarthritis (OA).A total of 69 OA knees that underwent OWHTO, with follow-up for a minimum of 10 years, were

Effect of Anterior Tibial Closing Wedge Osteotomy on Coronal Tibial Alignment in Relation to Preoperative Medial Proximal Tibial Angle and Wedge Height

The American Journal of Sports Medicine, 2023
Background: The posterior tibial slope has been identified as an anatomic risk factor for anterior cruciate ligament insufficiency and reruptures after anterior cruciate ligament reconstruction. Anterior tibial closing wedge osteotomy for correction of sagittal plane deformities has the potential to cause an ...

Poor Accuracy of Intraoperation Medial Proximal Tibial Angle Measurement Compared to Alignment Rod Methods in Open-Wedge High Tibial Osteotomy for Medial Knee Osteoarthritis

The Journal of Knee Surgery, 2022
AbstractThe alignment rod is widely used as an index for intraoperative alignment but alignment error is inevitable. The purpose of this study was to verify the accuracy of lower limb alignment correction by measurement of mechanical medial proximal tibial angle (MPTA) as an index in open-wedge high tibial osteotomy (OWHTO).

Determination of the Mechanical Medial Proximal Tibial Angle Using a Tangential Radiographic Technique

Veterinary Surgery, 2010
To assess whether there is a difference in the mechanical medial proximal tibial angle (mMPTA) measured on a tangential caudocranial (tCdCr) radiographic projection versus a straight caudocranial (sCdCr) projection before and after inducing a varus deformity in the proximal tibia.In vitro study.Cadaveric canine tibiae (n=4 pair).For each tibia, a ...

[Influence of axial rotation on measurement of medial proximal tibial angle].

Zhongguo gu shang = China journal of orthopaedics and traumatology, 2023
To measure and compare medial proximal tibial angle (MPTA) of lower limbs under different axial rotation angles(neutral position, 30° internal rotation, 30° external rotation) on the load position radiographs, and explore changes and significance of MPTA measured within and between groups of tibia at different axial rotation positions.From January 2018

Distal Femoral Rotation is not Associated With Preoperative Proximal Tibial Varus Angle in Patients With Isolated Medial Compartment Osteoarthritis

The Journal of Arthroplasty, 2019
Prior studies have found that greater proximal tibial varus was associated with increased external femoral rotation at time of total knee arthroplasty. These works suggest that measuring the tibial plateau-tibial shaft (TPTS) angle on preoperative weight-bearing long leg radiographs could predict significant variations in the posterior condylar angle.A

Results of proximal tibial osteotomy. The effects of tibiofemoral angle, stance-phase flexion-extension, and medial-plateau force

The Journal of Bone & Joint Surgery, 1976
Forty-eight knees were evaluated after proximal tibial osteotomy, performed for varus deformity to determine the desired amount of correction of the deformity, the effect of osteotomy on knee motion during gait and one medial-plateau force during standing, and the relationships between these factors and the result.

Bone marrow lesions and serum NTx predict varus change in medial proximal tibial angle in early knee osteoarthritis

Journal of Orthopaedic Science
We investigated the influence of abnormal magnetic resonance imaging findings and serum bone metabolism on varus deformity progression in the proximal tibia of women without radiographic abnormalities.A hundred and forty-six participants without radiographic knee osteoarthritis were assessed using a 5-year longitudinal analysis of the Iwaki cohort ...
