December 31, 2018 ORLANDO — At the Current Concepts in Joint Replacement Winter Meeting, Jeffrey B. Stambough, MD, discussed a study that looked at long-term outcomes of two consecutive groups of patients who underwent total hip arthroplasty with either conventional polyethylene or highly crosslinked polyethylene bearings. He said after a 15-year follow-up, highly crosslinked polyethylene bearings were an effective solution after patients younger than 50 years old underwent THA.
November 3, 2018 Dallas – Data presented at the American Association of Hip and Knee Surgeons Annual Meeting showed total hip arthroplasty performed with a highly crosslinked acetabular liner in patients younger than 50 years of age was associated with Kaplan-Meier overall survivorship of 93% at 15 years when revision due to failure was the endpoint.
August 2, 2018 – A long-term follow-up study from Australia confirms that hip implants with components made of cross-linked polyethylene (XLPE) substantially lower the risk of revision surgery after total hip replacement, reports a study in the August 1, 2018 issue of The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.
“The use of XLPE has resulted in a significant reduction in the rate of revision at 16 years following total hip arthroplasty for osteoarthritis,” writes Professor Richard de Steiger, MBBS, FRACS, FAOrthA, and colleagues of … Read the Rest
7/19/2018 – Ormonde M. Mahoney, MD, and Andrew M. Shimmin, MBBS, FRACS, debated the use of highly crosslinked polyethylene for patients who undergo total hip arthroplasty at the Orthopedics Today Hawaii Annual Meeting
He (Shimmin) emphasized that ceramic bearing wear products have less biological activity and minimal reports of osteolysis with its long-term use…
…Furthermore, Shimmin noted ceramic-on-ceramic bearings can be made with larger articulations, which can lead to greater jump height and more stability…
…“In the registry data that I presented yesterday, larger ceramic bearings are revised less than smaller diameter ceramic-on-ceramic bearings,” he said.… Read the Rest
…A small cup limits options regarding liner thickness and femoral implant size. The purpose of this study was to evaluate the safety of a 4-mm–thick ceramic liner and the outcomes of cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing…
…Between May 2003 and June 2008, 80 patients (88 hips) who had hip osteoarthritis and a hypoplastic acetabulum underwent cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing…
…The thin (4 mm) ceramic liner did not increase the risk of ceramic fracture and … Read the Rest
NEW ORLEANS, March 6, 2018 /PRNewswire/ — Corin, a global orthopaedic manufacturer and leader in functional implant positioning, today announced the launch of the Trinity™ Dual Mobility System featuring new implant technology designed to improve range of motion and reduce the risk for instability and dislocation after primary or revision hip replacement. The announcement was made here at the American Academy of Orthopaedic Surgeons (AAOS) 2018 Annual Meeting.
The system is designed for use with Corin’s Optimized Positioning System (OPS™), an innovative technology that helps surgeons determine the best positioning and orientation of a hip implant based on a dynamic … Read the Rest

Progress in hip replacement in hardware? Maybe not… Research Raises Questions About Innovations To Devices Used In Joint Replacement. Nancy Walsh writing in MedPage Today reported that a review published in BMJ suggests that “innovations to devices used in joint replacement have been introduced without sufficient evidence that they are any better than existing implants.” Researchers found that “for one type of new device technology, hip replacements with modular femoral necks, the cumulative rates of revision surgery at 5 and 10 years were 7.4% and 10.8%, compared with rates of 3.7% and … Read the Rest
Researchers from Massachusetts General Hospital (MGH) have developed an antibiotic-releasing polymer that may greatly simplify the treatment of periprosthetic joint infection, and in a recent report published in Nature Biomedical Engineering, they describe how implants made from this material successfully eliminated 2 types of prosthetic infection in animal models.
“Our finding that polyethylene, the most commonly used weight-bearing surface in total joint surgery, can be made to safely and effectively release antibiotics implies that fully weight-bearing implants made with this material could be used to treat infection in a single procedure, reducing both the inconvenience and … Read the Rest
The Medicines and Healthcare products Regulatory Agency (MHRA) UK has called for longer-term monitoring of all patients fitted with metal-on-metal hip implants, as a precautionary measure, in an update to its original guidance issued in 2012.
“MHRA, in colsultation with its independent Metal-on-Metal Expert Advisory Group (MoM EAG), has continued to monitor the performance of MoM hip joint articulations for the occurrence of soft tissue reaction associated with these devices. However, some patients will develop progressive soft tissue reactions to the wear debris associated with MoM articulations.”

The Orthopedic News Network estimated that about 460,000 people had hip replacements in 2010, and approximately 56,000 of those were revisions. Because hip replacements are on the rise in people under 60 (reports the Huffington Post and BBC News in 2016) doctors predict more hip revision surgeries.
Data from the Orthopedic Registry in both Australia and the United Kingdom indicate that only five percent of patients who receive total hip replacements require revision surgery within seven years. But 15 percent of metal-on-metal implant recipients in the U.K. registry and 8 percent in the Australian registry required … Read the Rest
