Introduction. The etiology of patellofemoral (PF) instability is multifactorial. Excessive
external tibial torsion has been associated with recurrent patellar subluxation and persistent …

Introduction A 'inwardly pointing knee'syndrome is a combined torsional deformity with
increased femoral internal and tibial external torsion. After clinical and radiological …

Background Rotational malalignment after operative fracture treatment of the lower extremity
may be associated with increased pain and functional impairment. Despite its clinical …

Purpose There is a lack of standardization in the measurement of lower limb torsional
alignment. Normal values published in the literature are inconsistent. A 3D-CT-scan-based …

Background Computed tomography (CT) scan is the standard for assessment of femoral
torsion. This observational study was conducted to evaluate the comparability of the EOS …

Purpose High tibial osteotomy with internal tibial derotation (high tibial derotation
osteotomy= HTDRO) is a common surgical treatment in patients with patellofemoral …

Background: Increased external tibial torsion and tibial tuberosity–trochlear groove distance
(TTTG) affect patellofemoral instability and can be corrected by tibial rotational osteotomy …

Purpose Postoperative assessment of surgical interventions for correcting femoral rotational
deformities necessitates a comparative analysis of femoral rotation pre‐and post‐surgery …

Introduction Miserable malalignment syndrome is a complex torsional lower limb deformity
with limited consensus on surgical treatment. We present the outcome of de-rotation of the …

Background: Different measures are used to describe relevant anatomic variations that can
result in patellofemoral instability and disorders. Knee version, the relative rotational …
