Purpose The purpose of this study is to systematically review and quantitatively analyse the
clinical outcomes of combined derotational distal femoral osteotomy (D‐DFO) and medial …

Purpose The purpose of this study was to evaluate the clinical outcomes of medial
patellofemoral ligament (MPFL) reconstruction combined with derotational distal femur …

Background: Increased femoral torsion (FT) or tibial torsion (TT) has been suggested to be a
potential risk factor for recurrent patellofemoral instability. However, the influence of …

Purpose The role of increased femoral antetorsion (femAT) as a contributor to patellofemoral
(PF) osteoarthritis (OA) is unknown. The purpose of this study was to investigate whether …

Background: Torsion of the lower extremities has been suggested to be a predisposing
factor for patellar instability. However, no clear torsional factors have been clarified. This …

Purpose Rotation of the tibia relative to the femur was recently identified as a contributing
risk factor for patellar instability, and correlated with its severity. The hypothesis was that in …

Purpose To evaluate the potential relationship between the tibial tubercle–trochlear groove
(TT-TG) distance and the femoral anteversion of different segments of the femur in patients …

Purpose The primary study objective was to describe the incidence of osteochondral
damage (OD) in our cohort of patients with patellar instability (PI). The secondary objective …

Purpose It has been widely reported that femoral anteversion is a risk factor for patellar
dislocation. This study aims to evaluate whether internal torsion of the distal femur is …

Purpose To perform a segmental analysis of tibial torsion in patients, with normal and
increased external tibial torsion, suffering from chronic patellofemoral instability (PFI) and to …
