Influence of preoperative coronal and sagittal tibiofemoral subluxation in knee osteoarthritis on the outcome of primary total knee arthroplasty
BackgroundThe effect of osteoarthritis (OA) with tibiofemoral (TF) subluxation on patients undergoing total knee arthroplasty (TKA) has been less...
-
Mal-angulation of femoral rotational osteotomies causes more postoperative sagittal mechanical leg axis deviation in supracondylar than in subtrochanteric procedures
PurposeAlteration of the postoperative frontal mechanical leg axis is a known problem in femoral rotational osteotomies. However, the maintenance of...

Variation of three-dimensional femoral bowing and its relation to physical status and bone mineral density: a study with CT
PurposeAnatomically, the femoral bone shows sagittal and coronal bowing. Pronounced bowing would affect femoral implant surgery accuracy, but factors...
-
The significance of the pelvic incidence measurement as a possible predictor of TKA outcome
PurposeTo evaluate the association between the sagittal alignment of the pelvis and residual knee flexion contracture after total knee arthroplasty...

Effect of age and sex on femoral curvature in the Japanese population: three-dimensional computed tomography findings
Age- or sex-related differences in femoral curvature affect the onset of trauma or degenerative diseases of the hip joints. This study aimed to...

Lower limb bone geometry in adult individuals with X-linked hypophosphatemia: an observational study
SummaryWe assessed lower-limb geometry in adults with X-linked hypophosphatemia (XLH) and controls. We found large differences in multiple measures...

Improved surgical procedure of primary constrained total knee arthroplasty which enables use of the femoral diaphyseal straight extension stem
BackgroundIn performing primary constrained total knee arthroplasties (TKA) to imbalanced knees, the offset stem is sometimes compelled to use,...
-
The accelerometer-based navigation system demonstrated superior radiological outcomes in restoring mechanical alignment and component sagittal positioning in total knee arthroplasty
BackgroundThis study aimed to determine whether the accelerometer-based navigation (ABN) could improve the accuracy of restoring mechanical axis...
-
Varus morphology and its surgical implication in osteoarthritic knee and total knee arthroplasty
BackgroundKnee varus alignment represents a notorious cause of knee osteoarthritis. It can be caused by tibial deformity, combined tibial–femoral...
-
Valgus arthritic knees can be classified into nine phenotypes
PurposeIt is not shown whether anatomical variations exist in valgus arthritic limbs as to support individualized component and limb alignment. The...
-
Short knee radiographs can be inadequate for estimating TKA alignment in knees with bowing
PurposeThe aim of this study was to compare the discrepancy of alignment categorization in total knee arthroplasty (TKA) between the anatomical...
-
Does patient-specific instrumentation increase the risk of notching in the anterior femoral cortex in total knee arthroplasty? A comparative prospective trial
PurposePatient-specific instrumentation (PSI) was usually applied in total knee arthroplasty (TKA) to acquire a favourable alignment. We hypothesized...
