Balancing the flexion gap first in total knee arthroplasty leads to better preservation of posterior condylar offset resulting in better knee flexion.

Purpose: The purpose of this study is to determine whether the flexion first balancing technique, developed in an attempt to solve the dissatisfaction due to instability in total knee arthroplasties, leads to better restoration of joint line height and medial posterior condylar offset. This might result in better knee flexion, compared to the classic extension first gap balancing technique. The secondary objective is to show non-inferiority of the flexion first balancing technique in terms of clinical outcomes as measured by the Patient Reported Outcome Measurements.

Medium-term outcome with contemporary mobile-bearing implants : results from a retrospective multicentre study.

Previous studies report good clinical outcomes with the initial mobile-bearing implant design in TKA. Nevertheless clinical data on the subject system are scant and information is lacking to fully appraise the safety and performance of the subject device. A population of 283 consecutive patients who received 307 primary Vanguard ROCC TKAs over a 5.

Vitamin D, calcium and albumin bloodserum levels in Belgian orthopedic patients - is systematic screening justified?

In the setting of fracture care, orthopedic surgeons are primarily focused on treating the fracture itself, but more and more attention is being paid to prevention of such fractures and identifying risk factors associated with worse postoperative prognoses. In our study we collected postoperative vitamin D, calcium and albumin bloodserum levels from 163 patients who were admitted with a femur fracture and from 233 patients who were admitted for an elective hip arthroplasty during the period of 365 days. Results : 84.

Functional and radiographic short-term outcome evaluation of the Visionaire system, a patient-matched instrumentation system for total knee arthroplasty.

Patient matched instrumentation is a new operative tool in the field of total knee arthroplasty. Custom made cutting blocks are designed to perform distal femoral and tibial bone cuts according to a pre-operative planning. This study evaluates the Visionaire system of Smith & Nephew.

Taper corrosion in modular hip prostheses: analysis of serum metal ions in 19 patients.

Recently, concerns have been raised about the use of metal-on-metal (MoM) implants. This has led to the recall of several resurfacing and large-diameter total hip arthroplasties (THA). Any MoM interface can be the cause of metal debris and adverse tissue reactions.

Osteochondral defect in femoral head: Trufit implantation under fluoroscopic and arthroscopic control.

Under arthroscopic control and guided by fluoroscopy, a Trufit Plug was successfully implanted to repair an osteochondral lesion of the head of the femur. The procedure was evaluated clinically using the HOOS score and Magnetic Resonance Imaging (MRI) of the hip. The short-term (6 months) clinical results are encouraging: the HOOS score improved clearly and the patient was satisfied.

Revising the well-fixed, painful resurfacing using a double-mobility head: a new strategy to address metal-on-metal complications.

Isolated revision of the femoral component of hip resurfacings to metal-on-metal (MoM) total hip arthroplasties has shown inferior results. We present a case series of well-fixed, painful MoM hips with elevated chromium and cobalt levels. An isolated femoral revision using a noncemented femoral component and a double-mobility head was performed.

Resurfacing hip arthroplasty. A 3 to 5-year matched pair study of two different implant designs.

We compared the 3 to 5 year clinical and radiological results of two different hybrid metal-on-metal resurfacing hip arthroplasty designs in 28 patients who had undergone bilateral hip resurfacing with ReCap implants on one side and BHR implants on the other side. Both hips were compared in each patient, to specifically evaluate the bone response to the cemented femoral component. Post operative function was measured with the Harris Hip Score and University of California at Los Angeles (UCLA) Activity Score, and was excellent in these patients.

Debonding of the acetabular porous coating in hip resurfacing arthroplasty. A case report.

This report presents the case of a patient in whom hip resurfacing arthroplasty failed because of loosening of the acetabular shell secondary to debonding of the surface coating. During normal function, there will inevitably be cyclic shear stress between the coating and the surrounding bone. This might result in fatigue failure of the bond.

Arthroscopic psoas release for iliopsoas impingement after total hip replacement.

Psoas impingement is a rare cause of persisting pain after hip arthroplasty. Diagnosis is based on clinical examination and exclusion of other complications after arthroplasty by radiographs, ultrasound, CT and blood analysis. The diagnosis is strongly supported by temporary pain relief after infiltration.

Variations in serum electrolyte concentrations and renal function after therapeutic hip arthroscopy: a pilot study.

Purpose: The purpose of this study was to analyze changes in serum electrolyte concentration and renal function after hip arthroscopy.

Methods: We studied 10 consecutive patients (4 men and 6 women; median age, 30.5 years [range, 20 to 50 years]) undergoing hip arthroscopy.
