New study explores outcomes of Charnley total hip replacement in patients under age 50

In a new study presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons, researchers sought to evaluate the clinical, radiographic and functional outcomes of a Charnley total hip replacement (THR)─ a traditional hip prosthesis consisting of a polyethylene acetabular (plastic) cup and a metal femoral head─in patients under age 50 at a minimum of 35 years after the initial surgery.

Study finds higher readmission rates for same-day total joint replacement surgery

As the effectiveness of anesthesia, pain management and rehabilitation continues to improve, more orthopaedic procedures are being done on an outpatient basis. In a new research study presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons, same-day total joint replacement (TJR) patient outcomes were comparable to those of patients admitted to the hospital and staying at least one night following surgery.

Study: Obese children more likely to suffer distal radius fracture

Children considered obese are more likely to suffer a distal radius fracture, a bone break near the wrist, and more likely to experience complications related to the healing of the fracture, according to research presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons.

Bariatric surgery may reduce knee pain in elevated BMI patients

There is a known link between elevated body mass index (BMI) and symptomatic knee osteoarthritis (OA). While patients who have undergone gastric bypass surgery (GBS)-a procedure that closes off much of the stomach and causes food to bypass a portion of the small intestine─typically lose weight, the comparative impact of this weight loss on knee pain and function has not been measured.

Sleep disturbance following fracture related to emotional well being, says study

Sleep disturbance is an extremely common complaint following orthopaedic trauma. In a new study presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers assessed the functional status of 1,095 patients following acute fractures to the proximal humerus (shoulder), distal radius (wrist), ankle and tibial plateau (shinbone), using standard orthopaedic tests and assessments.

Sutures embedded with stem cells led to quicker and stronger healing of Achilles tendon tears

Researchers have found that sutures embedded with stem cells led to quicker and stronger healing of Achilles tendon tears than traditional sutures, according to a new study published in the March 2014 issue of Foot & Ankle International (published by SAGE).

Patients should wait at least six weeks to resume driving following shoulder replacement surgery

More than 53,000 Americans have total shoulder joint replacement (SJR) surgery each year, and yet the effects of this surgery on a patient's ability to safely drive a vehicle, and the appropriate recovery time before patients should return to driving, have yet to be determined.

Study finds gene expression differences in male and female athletes with ACL injuries

Female athletes are two-to-eight times more likely to suffer an anterior cruciate ligament (ACL) injury than males. And while there have been reports about possible anatomic, hormonal and neuromuscular factors that may place females at greater risk for these injuries, little research has looked specifically at the role of genetics.

Study suggests surgical treatment for herniated discs increases savings to society over long term

Annually, more than 10 million people experience back pain in the United States. More than 200,000 of these patients undergo surgery to alleviate pain due to a herniated disc.

Optimizing patient health before total knee replacement surgery may reduce need for revisions

The number of total knee replacement (TKR) procedures continues to climb, as does the number of revision total knee replacement (RTKR) surgeries. In the study, "The Epidemiology of Revision Total Knee Arthroplasty in the United States," presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers used the Nationwide Inpatient Sample (NIS) to evaluate the cause of knee failure for 301,718 revision RTKR surgeries performed between 2005 and 2010.

New MRI can show detailed image following fracture repair without distortion by metal surgical screws

People who sustain the most common type of hip fracture, known as a femoral neck fracture, are at increased risk of complications. A special type of MRI developed at Hospital for Special Surgery in collaboration with GE Healthcare can show a detailed image following fracture repair, without the distortion caused by metal surgical screws that are problematic in standard MRIs.

Women are most likely to experience serious pain following knee replacement than men

Middle-aged women with rheumatoid arthritis or arthritis resulting from an injury are among the patients most likely to experience serious pain following a knee replacement, researchers from Hospital for Special Surgery (HSS) in New York have found.

Genetics may explain why some athletes are high functioning despite having hip abnormalities

Genetics may explain why some senior athletes are high functioning despite having one or both hip abnormalities typically associated with early onset osteoarthritis (OA): developmental dislocation of the hip (dysplasia), a loose hip joint; or femoroacetabular impingement (FAI), a condition in which the hip bones are abnormally shaped, according to new research presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS).
