"Ankle arthroplasties in the UK have a five-year survival rate of 90.2%, which is lower than recorded on the NJR, because approximately one-third of ankle arthroplasty failures are not reported to the NJR".

Images at 35.0 months of postoperative follow-up of the case in Supplementary Figure a. a) Anteroposterior radiograph of the pelvis. b) Coronal and sagittal CT scans. c) Coronal and sagittal MRI. The femoral head shows mild signs of arthritis but uniform density, with signs of repair in the necrotic area and no collapse occurring.

Imaging examinations showed a marked improvement in the contour of the femoral head in the weightbearing area and the congruency with the acetabulum immediately postoperatively.

The gluteus medius can be considered both anatomically and functionally as two separate muscles. The posterior portion is highlighted in green, and functionally these muscle fibres act as a lateral stabilizer of the hip.

Dislocation is a leading cause of failure following revision THA, and while surgeons appreciate the impact that soft-tissue deficiency has on stability, it has been poorly described in the literature.

An example of a Vancouver B2 periprosthetic fracture on an anteroposterior radiograph in a 75-year-old female sustained a) one month postoperatively in a patient in the collarless group, and b) after revision.

These results support the preference for collared versus collarless cementless stems, particularly in patients who are at a high risk of PPF, to enhance the initial stability of the stem and reduce complications.

a) Native femoral anteversion and b) component anteversion were defined as the angle between the axis joining the centre of the femoral head and neck and the posterior condylar axis, measured in the plane perpendicular to the long axis of the femur (defined as the axis from the midpoint of the medial and lateral condyles and the piriformis fossa).

The primary aim of this study was to compare the effect of the direct anterior approach to a standard posterior approach on cementless femoral component version relative to the native femoral version.

Anteroposterior radiograph of the pelvis at one year. The left hip is normal. The right hip has a smaller ossific nucleus of the femoral head, lateralization of the femoral head (borderline International Hip Dysplasia Institute grade 1 or 2), and a higher acetabular index than the left side.
