Curve-on-curve technique is more reliable than free-floating technique for tibial components positioning in posterior stabilized total knee arthroplasty using symmetrical tibial components in varus osteoarthritis.

Introduction: Malrotation of the tibial components in total knee arthroplasties is a common cause of pain and functional impairment. There are multiple methods used to establish the tibial component rotation, but there is still no consensus which method is the best.The objective of this study was to compare two of the most commonly used techniques, that is the use of self-alignment during passive range of motion (free-floating technique) versus the anterior cortex referencing method (Curve-on-curve technique).

Extracorporeal Shock Wave Therapy vs. Corticosteroid Local Injection in Shoulder Impingement Syndrome : A Three-Arm Randomized Controlled Trial.

Objective: The aim of this study was to examine the effects of combining extracorporeal shock wave therapy or local corticosteroid injections with a conventional physical therapy (CPT) program for patients with shoulder impingement syndrome.

Design: This was a prospective single-blinded, randomized controlled study.

Methods: Sixty patients with unilateral shoulder impingement syndrome >3 mos were allocated to group A (a 4-wk program of CPT plus a single local corticosteroid injection of 40 mg triamcinolone acetonide mixed with 1% xylocaine, n = 20), group B (CPT only, n = 20), and group C (CPT plus extracorporeal shock wave therapy, 2000 impulses, 0.

Ganz osteotomy for treatment of hip dysplasia through intra-pelvic approach. Early results.

Ganz periacetabular osteotomy (PAO) is a technically demanding surgical procedure. It requires cutting around the acetabulum to mobilize it under fluoro- scopic control. The radiolucent table and good quality imaging are mandatory to perform this osteotomy in a safe way.

Can polyaryletherketone cage be used to achieve union and maintain correction in anterior calcaneal lengthening osteotomy for treatment of flexible flatfoot?

A structural graft is often used to maintain correction and achieve union after anterior calcaneal lengthening osteotomy for treatment of flexible flatfoot. Autograft, the current gold standard, is limited in availability and configuration and is associated with donor site morbidity in as much as 48%, whereas the alternative allograft carries risks of disease transmission and collapse. Polyaryletherketone cage, with a healing rate similar to that of autograft, high stability, and no donor-site morbidity, has been used in spine surgery.

Conventional versus direct magnetic resonance imaging in detecting labral lesions in femoroacetabular impingment - a retrospective multicenter study.

The purpose of this study was to assess the reliability of Direct Magnetic Resonance Arthography (MRA) and Conventional Magnetic Resonance Imaging (MRI) in diagnosing labral lesions in patients with symptoms of femoroacetabular impingement (FAI). Materials and methods: Imaging and surgical data (n=490) were retrospectively collected from 5 high-volume centres providing arthroscopic treatment of FAI patients. Preoperative magnetic resonance imaging findings were compared with the actual surgical findings regarding labral condition in order to assess the effectiveness of MRI and MRA in identifying the presence of labral tears in patients with FAI.
