Magnetic resonance imaging assessment of tibial tuberosity-trochlear groove distance: normal values for males and females.

Purpose: The aim of this study was to report normal values of the tibial tuberosity-trochlear groove distance (TTTG) in males and females and assess the reliability of MRI in measuring TTTG.

Methods: Patients presenting with a suspected meniscus injury without any patellofemoral or ligamentous instability, and arthroscopically normal cruciate ligaments and patellofemoral joints were included in the study. K-PACS© was used for MRI analysis and was performed by three observers blinded to each others' measurements.

Loss of tibial bone density in patients with rotating- or fixed-platform TKA.

Little is known about tibial bone remodeling with TKA and its clinical relevance. We performed a randomized clinical trial to compare tibial bone density changes in cemented components with different bearing designs. Bone density changes were assessed using quantitative computed tomography (qCT)-assisted osteodensitometry.

Retroacetabular stress-shielding in THA.

We conducted a randomized clinical trial to compare periacetabular bone density changes after total hip arthroplasty using press-fit components with soft and hard liner materials. Bone density changes were assessed using quantitative computed tomography-assisted osteodensitometry. Twenty press-fit cups with alumina ceramic liners and 20 press-fit cups with highly cross-linked polyethylene liners were included; the nonoperated contralateral side was used as the control.

Inter-observer validation study of quantitative CT-osteodensitometry in total knee arthroplasty.

Introduction: Proximal tibial bone quality is an important factor in implant mechanical stability following total knee arthroplasty. Quantitative computed tomography (CT) osteodensitometry has been used to measure the change in bone density post-operatively. We sought to validate the inter-observer reliability of these measurements.

Quantitative CT-assisted osteodensitometry of femoral adaptive bone remodelling after uncemented total hip arthroplasty.

The aim of this prospective study was to measure bone density changes and to assess adaptive bone remodelling after uncemented total hip arthroplasty with a taper-design femoral component using quantitative computer-tomography-assisted osteodensitometry. This method is able to differentiate cortical and cancellous bone structures. Twenty-seven consecutive patients (29 hips) with degenerative joint disease were enrolled in the study.

Periprosthetic femoral fractures after total hip arthroplasty.

Background: The management of periprosthetic fracture following a total hip arthroplasty is difficult, requiring expertise in both trauma and revision surgery. With rising numbers of patients in the population living with hip prostheses in situ, the frequency of these fractures is increasing, and controversy remains over their ideal management. The objective of this study was to review all periprosthetic fractures at a single institution to identify injury and treatment patterns and their associated clinical outcomes.

Computed tomography assisted osteodensitometry in total hip arthroplasty.

Background: Periprosthetic bone remodelling is an important issue in total hip arthroplasty, which can compromise long-term outcomes. The aim of this study was to evaluate bone remodelling of the proximal femur with an uncemented hydroxyapatite-coated taper stem.

Methods: Twenty-three patients (27 hips) were included in this study.

Prostate cancer screening: knowledge, experiences and attitudes of men aged 40-79 years.

Aim: The purpose of this study was to explore the knowledge, experiences and attitudes of men aged 40-79 years regarding screening for prostate cancer.

Methods: This study was a cross-sectional telephone survey of men aged 40-79 years whose names were randomly selected from the Auckland telephone directory. The study was undertaken in the summers of 2000/2001 and 2001/2002.
