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.
Below is a news summary of an orthopaedic research study appearing in the March 21, 2012 issue of the Journal of Bone and Joint Surgery (JBJS), as well as the issues' full Table of Contents.
SpinalMotion, developer of the investigational Kineflex lumbar and Kineflex|C cervical disc implants for treating degenerative disc disease (DDD), today announced that it has received CE Mark for two sub-5mm Kineflex|C cervical total disc replacements to address the widest range of patients by best matching disc height to the existing anatomy.
Vejthani Hospital Bangkok offers Unicompartmental Knee Arthroplasty to get better range of motion at Vejthani TJR center, the top international hospital in Thailand.
According to the results of a new study published in the March 2012 issue of the Journal of the American College of Surgeons, patients who score highest on the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) experience longer postoperative hospital stays and more days in the intensive care unit (ICU); they are also more likely to return to the operating room (OR) within 30 days of a surgical procedure than patients with low AUDIT-C scores.
In a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers completed a systematic review of three major orthopaedic journals - the Journal of Bone and Joint Surgery (American and British editions) and the Journal of Arthroplasty (JOA) - for all articles related to metal-on-metal total hip replacement between October 1999 and May 2011.
In their search for new, better ways to diagnose periprosthetic joint infection, Rothman Institute at Jefferson researchers have discovered that measurement of C-reactive protein in the synovial fluid is extremely accurate, while measuring a patients- serum white blood cell count (WBC) and the percentage of neutrophils (PMN%), the conventional method for diagnosis, has a minimal role in the determination of PJI.
In hip resurfacing the femoral ball in the hip joint is not removed, but instead is trimmed and capped with a smooth metal covering. Young and active patients with arthritis often choose hip resurfacing over total hip replacement to minimize the risk of hip dislocation, and to preserve the bone for a revision surgery should the primary resurfacing fail. However, the long-term effects of sports on a resurfaced hip were unknown.
The elevated risk of pulmonary embolism (PE) - a blood clot that travels from the leg to the lungs - following total joint replacement (TJR) surgery has been well established, yet little is known about the natural course and timing of this potentially fatal condition.
Rothman Institute at Jefferson joint researchers continue to seek better ways to diagnose and subsequently treat periprosthetic joint infection (PJI) in patients following total joint arthroplasty. Their latest research shows leukocyte esterase reagent (LE) strips, common in diagnosing urinary tract infections, can also have a role in rapid diagnosis of PJI.
Experts from the Department of Orthopaedic Surgery at NYU Langone Medical Center will present their latest research and clinical findings on diseases of the muscle, tendon, bone and joint at the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS), February 7-11 in San Francisco, California.

In patients undergoing hip replacement surgery, using a special wound catheter to infuse local anesthetic directly into the hip joint provides significant and lasting improvements in postoperative pain control, reports a study in the February issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.
Researchers in Finland found that annual cumulative incidences of partial and total knee arthroplasty, commonly known as knee replacement surgery, rose rapidly over a 27-year period among 30 to 59 year-olds in that country, with the greatest increase occurring in patients aged 50 to 59 years.
Despite increased use of total hip arthroplasty (THA) and total knee arthroplasty (TKA), there is a notable lack of consensus about optimal postoperative treatment. Aquatic therapy has been shown to have a beneficial effect, and it is typically begun two weeks after surgery, after the wound has healed.
Researchers in Norway report that patients who receive walking skills training following total hip arthroplasty for osteoarthritis show improved physical function. The physical therapy program displayed a positive effect on walking distance and stair climbing which continued 12 months following hip replacement surgery.
Orthopaedic surgeons face a steep learning curve to get used to new prostheses, and the instruments and methods that go with them, before new total knee replacement procedures are as safe and effective as conventional methods. Patients who undergo the first 15 operations using a new device in a hospital are 48 percent more likely to need early revision surgery, than patients undergoing an operation to fit a prosthesis previously used in the hospital.
Investigators from Hospital for Special Surgery have identified factors that are associated with an increased risk of in-hospital falls after total hip or knee replacement surgery.
Vejthani Hospital Bangkok offers Computer Assisted Replacement Surgery on knee arthroplasty, the intelligent medical surgery software at TJR Center of Vejthani Hospital.
Tornier N.V., a global medical device company focused on providing surgical solutions to orthopaedic extremity specialists, reported sales of $57.6 million for the third quarter of 2011 compared to sales of $49.7 million for the third quarter of 2010, an increase of 16% as reported and 11% in constant currency.
Compared with osteoarthritis patients, individuals with rheumatoid arthritis who undergo total knee replacement surgery have lower expectations about their postsurgical outcomes, according to a new study by researchers at Hospital for Special Surgery (HSS) in New York City.
