Treating cam-type hip impingement yields improved hip scores at early follow-up
Source - ORTHOSuperSite
Arthroscopic osteoplasty to manage cam-type femoral acetabular impingement was found to improve hip function at early follow-up in a study presented by a British investigator at the Current Concepts in Joint Replacement 2011 Winter Meeting, here.
However, the relative contributions of cam impingement correction and labral/chondral hip surgery remain unclear, according to Fares S. Haddad, McH(Orth), FRCS, an Orthopaedics Today Europe Editorial Board member.
"We have an improved understanding of the influence of hip anatomy and mechanics on hip symptoms and disease. Our tools for dealing with hip pathology are also evolving dramatically," Haddad said during his presentation.

Low revision rates associated with tapered rectangular hip stem
Source - ORTHOSuperSite
Femoral fixation of a cementless total hip arthroplasty using a tapered, rectangular stem made of titanium-aluminum-niobium alloy continues to be secure at 20-years follow-up, according to a recently presented study.
"The most important result of study is the low rate of revisions of the femoral component, with 97% survivorship," Alexander Kolb, MD, said during his presentation at the 12th EFORT Congress 2011. "The low rate of femoral osteolysis in the medial and distal Gruen zones proves the stability of the osseous integration of the stems at follow up."
Kolb, of the department of orthopedics and orthopedic surgery at Medical University of Vienna, and colleagues evaluated the stability of the Zweymüller (Zimmer) stem for cementless total hip arthroplasty.

Osteonecrosis not a predictor of THA revision
FRIDAY, October 28, 2011 — Osteonecrosis is not a predictor of poor outcomes in primary total hip arthroplasty, even when associated with other common risk factors, and total hip arthroplasty revision rates have improved since 1990, according to a study presented by Henning R. Johansson at the SICOT XXV Triennial World Congress 2011.

Patients return to work after total hip arthroplasty with preoperative function
FRIDAY, October 28, 2011 — The majority of working-age patients can return to their jobs after total hip replacement procedures and perform their jobs at preoperative levels, according to a presenter at the SICOT XXV Triennial World Congress 2011.
Turnbull said that age and body mass index were significantly related to recovery time and return to work, while gender was not a factor. Less than half the patients could return to light exercise. No significant correlation was found between patients who reported a restriction at work and postoperative pain scores, SF12 scores, or Oxford hip scores, the authors wrote.

Modified straight stem's curvature allows implantation in narrow femoral cavitiesF
THURSDAY, October 27, 2011 — Researchers reported successful outcomes using a modified straight cementless hip stem with proximal-medial curvature for proximal fixation in total hip arthroplasty, according to a study presented at the SICOT XXV Triennial World Congress 2011.
"Most studies … say narrow femoral bone conditions can be challenging," Steffen Kohler, said. "The small shape of stem designs may change outcomes dramatically."

Link between Cam-Type Deformities and MRI Detected Hip Damage in Asymptomatic Young Men, Potential Progression to Osteoarthritis of the Hip
Hip impingement (femoracetabular impingement) may be a risk factor of osteoarthritis (OA) of the hip. A new study reveals that the presence of an underlying deformity, known as cam impingement, is associated with hip damage in young men without any arthritis symptoms and detected using magnetic resonance imaging (MRI). Full findings are now published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR).

Potential to Diagnose, Prevent Osteoarthritis
A new method is set to help doctors diagnose osteoarthritis at such an early stage that it will be possible to delay the progression of the disease by many years, or maybe even stop it entirely.
One of the problems with osteoarthritis has been diagnosing and monitoring the disease before symptoms become evident. It has therefore been difficult to change or delay the course of the disease. A few years ago, researchers from Lund University and Harvard Medical School developed a method to measure the degree of osteoarthritis using an MRI scanner, even at a very early stage. The method is called dGEMRIC (delayed gadolinium-enhanced MRI of cartilage).

Reducing Blood Clots after Hip and Knee Replacement: New Clinical Treatment Guideline Outlines Recommendations
An updated clinical practice guideline released by the American Academy of Orthopaedic Surgeons (AAOS) Board of Directors recommends how to reduce the likelihood of blood clots after hip or knee replacement surgery, procedures that more than 800,000 Americans undergo each year. The new guideline suggests use of preventive treatments and advises against routinely screening patients after surgery using ultrasound imaging.

FDA Approves XARELTO® (rivaroxaban Tablets) to Help Prevent Deep Vein Thrombosis in Patients Undergoing Knee or Hip Replacement Surgery
SATURDAY 02 July, 2011 — Janssen Pharmaceuticals, Inc. announced that the U.S. Food and Drug Administration (FDA) has approved XARELTO® (rivaroxaban tablets), a novel, once-daily, oral anticoagulant for the prevention (prophylaxis) of deep vein thrombosis (DVT) which may lead to a pulmonary embolism (PE) in people undergoing knee or hip replacement surgery.
"The use of blood thinners has been shown to safely and effectively help keep people from developing preventable blood clots," said Alan Brownstein, Chief Executive Officer of the National Blood Clot Alliance. "The FDA approval of a new blood thinner, XARELTO®, offers a new option for patients seeking knee or hip replacement surgery, and we encourage people to discuss with their physicians the risk of blood clots and which blood thinner offers optimal protection as part of their pre-surgical consultation."

Hip strengthening program improved single leg squatting mechanics
WEDNESDAY 10 August, 2011 – A strengthening and movement program that targeted the hip abductors and hip external rotators did not alter abnormal running mechanics, according to results of a block randomized controlled trial.
"Abnormal movement patterns during running and single leg squatting have been associated with a number of running related injuries in females," the authors wrote. Typically, hip strengthening is used to correct these aberrant movements. While strengthening improves symptoms, it is unclear if the underlying mechanics during functional movements are changed.

Adolescent participation in high-intensity sports linked to high osteoarthritis rates
TUESDAY 26 July, 2011 – Participation in vigorous sporting activities during childhood and adolescence can cause abnormal development of the femur in young athletes and may lead to hip deformation, such as reduced rotation and pain during movement, according to Swiss researchers.
The findings, published online in Clinical Orthopaedics and Related Research, may explain why athletes are at higher risk than more sedentary individuals to develop osteoarthritis.
"Our data suggest that this hip deformity is in part a developmental deformity, and its expression in young adulthood may be triggered by environmental factors such as high-level sports activity during childhood and around the time of closure of the femoral growth plate," the Klaus A. Seibenrock, MD, and his fellow authors wrote.

MRI Techniques Can Detect Early Osteoarthritis
TUESDAY 16 August, 2011 – Researchers from NYU Langone Medical Center's Departments of Orthopaedic Surgery and Radiology found that advanced MRI techniques can be used to detect subtle changes in joint cartilage microstructure and provide physicians a diagnostic tool for finding key markers of early osteoarthritis (OA). By using these techniques during patient exams to identify OA earlier, clinicians can shift the management of the disease from eventual joint reconstruction to long-term preservation. The study was published in the July issue of the Journal of the American Academy of Orthopaedic Surgeons.
"Imaging technology is now sensitive and powerful enough to enable detection of subtle changes in the intricate balance of water, chondrocytes and the collagen fibers and protein molecules that make up our joint cartilage which we now know can point to future osteoarthritis," says Laith Jazrawi, MD, associate professor of orthopaedic surgery and lead author of the paper.

Future of replacement may include more resurfacing, percutaneous fixation
August 2011 – As we enter our sixth decade of total hip replacement and our fifth decade of total knee replacement, the orthopedic community can take pride in the substantial improvements that have been made in these operations which produce validated improvements in patients' lives. The incidence of two of the most feared complications of joint replacement, infection and thromboembolic disease, has been substantially reduced. In addition, the incidence of instability in total hip replacement has decreased significantly, and the length of hospital stays has decreased remarkably for hip and knee replacement. Despite these improvements, there is a real interest by patients for "less invasive, faster recovery" surgery modifications.
