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.
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.
Spinal anesthesia could reduce the risk for postoperative complications in select patients undergoing total knee arthroplasty, US researchers say.
Many of the most common inpatient surgeries in the United States are performed electively. These surgeries are expected to significantly increase with the enactment of the Affordable Care Act.
The long-term outcome of hip and knee arthroplasty may be significantly influenced by comorbidity, suggest results from a large register-based study of over 96,000 osteoarthritis patients.
Arthritis translates to “joint inflammation.” The most common form of arthritis is osteoarthritis (OA), which affects 12-15% of North Americans over the age of 60, and will increase in prevalence as our population ages.
Cempra, Inc., a clinical-stage pharmaceutical company focused on developing antibiotics to meet critical medical needs in the treatment of bacterial infectious diseases, today announced the initiation of its Phase 2 clinical trial of CEM-102 in patients with prosthetic joint infections (PJIs).
Cervical disc replacement is a surgical procedure that involves removing a damaged or degenerated cervical disc and replacing it with an artificial disc device.
Results of a review demonstrate the key role orthopedic surgery can play in the care of breast cancer patients with bone metastases.
In the first systemic review of evidence assessing complications following total joint arthroplasty, patients with rheumatoid arthritis (RA) were found to have an increased risk for hip dislocation after hip replacement surgery compared to those with osteoarthritis (OA). Study findings published online in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), also indicate that RA patients have a higher infection risk following total knee replacement than patients with OA.
For many years, the use of computer-assisted navigation has been touted as improving the positioning, sizing and alignment of replacement knee joints, resulting in greater durability of joints and overall improvement in patient movement. However, new research published in the Journal of Bone and Joint Surgery (JBJS) found no difference in knee function, alignment or durability/survivorship between joints positioned and completed with the help of computer navigation, and those replaced with conventional total knee arthroplasty (TKA) procedures.
Repeat doses of corticosteroids may protect patients undergoing bilateral total knee arthroplasty from postoperative side effects such as fever, pain, and acute respiratory distress, research suggests.
Tornier N.V., a global medical device company focused on providing surgical solutions to orthopaedic extremity specialists, today reported its financial results for the third quarter ended September 30, 2012 and updated its fiscal 2012 financial outlook.
Isis Pharmaceuticals, Inc. announced the initiation of a Phase 2 comparator-controlled study evaluating ISIS-FXIRx in patients undergoing knee replacement surgery, also referred to as total knee arthroplasty (TKA).
Using regional anesthesia rather than general anesthesia reduces the need for blood transfusions in patients undergoing bilateral total knee replacement, according to a new study by researchers at Hospital for Special Surgery, in New York City.
Patient age and gender have a significant effect on the risk for revisions after primary total hip replacement, show study findings.
Obese patients have a greater risk of complications following total knee replacement surgery, including post-surgical infections, according to a new literature review recently published in the Journal of Bone and Joint Surgery (JBJS).
