AIMS One goal of total hip arthroplasty is to restore normal hip anatomy. [] Key Method Anteroposterior pelvic radiographs were analysed for acetabular floor depth and vertical and horizontal position of the COR. RESULTS Horizontally, the mean medial displacement of the COR was 0.8 mm (standard deviation (sd) 1.4) in the peripheral remaing group and 5.0 mm (sd 3.30) in the standard reaming group (p < 0.001).

Impact of acetabular reaming depth on reconstruction of rotation center in primary total hip arthroplasty

The reaming depth of the acetabulum could influence the reconstruction of RC during UPTHA and when the medial margin of the cup was placed about 2 mm to the lateral border of the ipsilateral teardrop, the rotation center would be accurately restored.

Effects of the depth of the acetabular component during simulated acetabulum reaming in total hip arthroplasty

Although the acetabular component coverage rate is larger with conventional reaming technique, anatomical technique provides less micromotion and stress concentration for initial cup stability, indicating that anatomical technique may be more suitable for acetabulum reaming during primary total hip arthroplasty.

Revision of a Failed Primary Total Hip Arthroplasty following Excessive Reaming with a Medial Cup Protrusion

Following excessive reaming, the acetabular component was placed too far medially and resulted in an intrapelvic cup protrusion and surgeons should be aware of that rare and probably underreported complication and restore the anatomic center of rotation by treating the defect intraoperatively.

Total hip arthroplasty with a superior approach and in situ preparation of the femoral stem: technique and feasibility in a prospective series of 80 cases.

We report on the feasibility of a technique for total hip replacement with in situ preparation of the femoral stem through a superior approach and with the use of standard instruments. From December

Current Concepts in Acetabular Positioning in Total Hip Arthroplasty

This review article brings together the evidence on cup positioning and aims to provide a systematic and pragmatic approach in achieving the best position in individual cases.

Greater increase in femoral offset with use of collum femoris-preserving stem than Tri-Lock stem in primary total hip arthroplasty

Both stems similarly improved hip function and reconstructed the leg length, but the CFP stem was superior to the Tri-Lock stem in reconstructing FO.

Supine versus lateral position for total hip replacement: accuracy of biomechanical reconstruction

For a surgical target of reconstructing both leg length and total offset within 5 mm of native anatomy, the supine group was more than twice as likely to achieve these goals with fewer outliers (OR 2.631, 95% [CI] 1.901–3.643).

Does body mass index affect restoration of femoral offset, leg length and cup positioning after total hip arthroplasty? A prospective cohort study

Increased BMI showed a negative effect on restoration of post-THA leg length but not on Restoration of FO or positioning of the acetabular cup, and age, gender, OA duration or radiological severity and surgeon’s experience showed no relation to post- THA restoration of FO, leg length or cup positioning.



Do We Medialise the Hip Centre of Rotation in Total Hip Arthroplasty? Influence of Acetabular Offset and Surgical Technique

In patients with significant AO, surgeons should pay close attention to the preparation of the acetabulum, and the concept of hip offset cannot be limited to that of the femoral offset.

The Effect of Superior Placement of the Acetabular Component on the Rate of Loosening after Total Hip Arthroplasty. Long-Term Results in Patients Who Have Crowe Type-II Congenital Dysplasia of the Hip*

It is suggested that superior positioning of the acetabular component, even without lateral displacement, leads to increased rates of loosening of the femoral and acetABular components.

The use of the transverse acetabular ligament for determining the orientation of the components in total hip replacement: a randomised controlled trial.

A prospective, randomised, controlled trial of two groups, comprising of 40 patients each, in order to compare freehand introduction of the component with introduction using the transverse acetabular ligament (TAL) as a reference for anteversion.

Fixation method does not affect restoration of rotation center in hip replacements: A single-site retrospective study

The hip rotation center was similarly restored using either the cemented or cementless fixation techniques in this patient cohort, indicating that the fixation technique itself does not interfere with the position of the center of rotation.

Changes of center of rotation and femoral offset in total hip arthroplasty.

The results indicate a potential for better restoring the location of COR and femoral offset when planning and implanting an uncemented THA and free hand technique, and a fair reproducibility of anatomy.


A significant relationship was identified between increasing vertical displacement of the HJC and worsening patient functional outcome, which supports current opinion regarding the disadvantageous consequences of a superiorly displaced HJC in terms of survivorship and function.

Are leg length and hip offset comparable after hip resurfacing and cementless total hip arthroplasty?

Leg length is restored by HRA and THA and a difference remains in offset after HRA although the authors attribute this to intentional medialisation of the acetabular cup.
