Arthroplasty News and Research RSS Feed - Arthroplasty News and Research

Arthroplasty is a orthopaedic surgery procedure, in which the arthritic or dysfunctional joint surface is replaced with something better or by remodeling or realigning the joint by osteotomy or some other procedure. Previously, a popular form of arthroplasty was interpositional arthroplasty with interposition of some other tissue like skin, muscle or tendon to keep inflammatory surfaces apart or excisional arthroplasty in which the joint surface and bone was removed leaving scar tissue to fill in the gap. Other forms of arthroplasty include resection(al) arthroplasty, resurfacing arthroplasty, mold arthroplasty, cup arthroplasty, silicone replacement arthroplasty, etc. Osteotomy to restore or modify joint congruity is also an arthroplasty.

Lower-income individuals are more likely to report dissatisfaction with knee replacement surgery

Knee replacement surgery is a very common procedure. However, it does not always resolve function or pain in all the recipients of new knees. [More]
Metal-on-metal hip implants cause inflammation of joint lining long before symptoms appear

Metal-on-metal hip implants cause inflammation of joint lining long before symptoms appear

Metal-on-metal hip implants can cause inflammation of the joint lining (synovitis) long before symptoms appear, and magnetic resonance imaging (MRI) can be used to identify this inflammation, according to a new study by researchers at Hospital for Special Surgery. The study, which appears in an upcoming issue of the Journal of Bone & Joint Surgery, demonstrates that MRI can be used to identify implants that are going to fail before people become symptomatic.

SAGE announces launch of new international open access journal of sports medicine

SAGE announces launch of new international open access journal of sports medicine

SAGE today announces the launch of a new international open access journal, the Orthopaedic Journal of Sports Medicine. This journal was developed by the American Orthopaedic Society for Sports Medicine in collaboration with professional sports medicine organizations from around the world as a global, peer-reviewed open access journal that will publish content for both researchers and practitioners studying orthopeadic sports medicine, arthroscopy, and knee arthroplasty.

Regional anesthesia improves outcomes in sleep apnea patients undergoing total joint arthroplasty

Regional anesthesia improves outcomes in sleep apnea patients undergoing total joint arthroplasty

Using regional anesthesia instead of general anesthesia in patients with sleep apnea undergoing total joint replacement decreases major complications by 17%, according to a study published online, ahead of print, in the journal Regional Anesthesia and Pain Medicine. [More]
Neuraxial anesthesia improves outcomes in patients undergoing hip or knee replacement

Neuraxial anesthesia improves outcomes in patients undergoing hip or knee replacement

A highly underutilized anesthesia technique called neuraxial anesthesia, also known as spinal or epidural anesthesia, improves outcomes in patients undergoing hip or knee replacement, according to a new study by researchers at Hospital for Special Surgery. [More]

Obesity may not diminish outcomes or increase risk of complications in total knee replacement patients

Obesity may not diminish outcomes or increase risk of complications in total knee replacement patients

Obesity alone may not diminish outcomes or increase the risk of complications in total knee replacement (TKR) patients, according to two research studies presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). However, TKR replacement patients may face significantly longer hospital stays and related costs. [More]
Smoking prolongs healing time, poses greater risk for complications in orthopaedic surgeries

Smoking prolongs healing time, poses greater risk for complications in orthopaedic surgeries

Smoking has been linked to prolonged healing time and greater risk for complications in orthopaedic and other surgeries, according to a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). [More]
Tissue damage causes unexplained pain among metal-on-metal hip implant patients

Tissue damage causes unexplained pain among metal-on-metal hip implant patients

The cause of unexplained pain among metal-on-metal hip implant patients is more likely to be tissue damage than wear of the implant, Hospital for Special Surgery researchers have found. [More]

MRI identifies tissue damage in MoM total hip replacement patients

Magnetic Resonance Imaging can detect a failing, or potentially failing, metal-on-metal hip implant (MoM) early on, according to a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons. [More]
Study: Total knee replacements in younger patients with juvenile arthritis last for 10 years

Study: Total knee replacements in younger patients with juvenile arthritis last for 10 years

When you think of knee replacement surgery, you generally envision an older adult with painful arthritis. But the procedure is also used for younger patients with juvenile idiopathic arthritis whose joints have been severely damaged by the disease. Because the surgery in younger patients is relatively rare, little data exist on the longevity of knee replacements in JIA patients. [More]
Weight loss may help prevent and alleviate symptoms of osteoarthritis

Weight loss may help prevent and alleviate symptoms of osteoarthritis

Weight loss may prevent and significantly alleviate the symptoms of osteoarthritis, a progressive disease of the joints known as "wear and tear" arthritis, according to a literature review appearing in the March 2013 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS).

Patients with diabetes at no increased risk of complications after total knee replacement

Patients with diabetes at no increased risk of complications after total knee replacement

Patients with diabetes who undergo total knee replacement surgery do not have increased risk of surgical complications compared to those patients without diabetes, according to a Kaiser Permanente study published today in The Journal of Bone and Joint Surgery. [More]

Adynxx initiates AYX1 Phase 2 study to prevent post-surgical pain

Adynxx, a clinical-stage pharmaceutical company developing a first-in-class platform of therapeutics to address pain at its molecular roots, announced today that the first patient was dosed in a Phase 2 study of its lead investigational drug candidate for the prevention of post-surgical pain, AYX1.

Gender bias detected for hip arthroplasty failure

Women are significantly more likely than men to experience implant failure after primary total hip arthroplasty, suggests research published in JAMA Internal Medicine. [More]

Women appear to have increased risk of implant failure following total hip replacement

Women appear to have a higher risk of implant failure than men following total hip replacement after considering patient-, surgery-, surgeon-, volume- and implant-specific risk factors, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication. [More]

Opaque procedure pricing barrier to healthcare reforms

US investigators report great difficulty in obtaining price information for total hip arthroplasty from healthcare providers, with many institutions and physicians unable to provide reasonable price estimates. [More]
Knee replacement pain predicted by comorbidity

Knee replacement pain predicted by comorbidity

Research may help physicians give patients undergoing total knee arthroplasty a realistic expectation of surgery outcome based on their overall physical and mental health, US researchers believe. [More]

Anesthesia choice may benefit knee arthroplasty patients

Spinal anesthesia could reduce the risk for postoperative complications in select patients undergoing total knee arthroplasty, US researchers say. [More]
