Arthroplasty News and Research

RSS

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.

DePuy Synthes knee system shown to be beneficial for economics and patient reported outcomes

DePuy Synthes*, part of the Johnson & Johnson Family of Companies, released a new report, "Improving the Value of Primary Total Knee Arthroplasty: the ATTUNE® Knee System," that analyzes the ATTUNE Knee's current clinical and economic data. The report concludes that in a value-based healthcare environment with cost constraints and growing procedure volumes, the value of a knee replacement implant is measured not only by how long the implant lasts (implant survivorship), but also through patient reported outcomes and the economic benefits of the procedure.

Avoiding post-operative surgical precautions may lead to better inpatient rehabilitation outcomes

Avoiding the typical post-surgical precautions after hip replacement surgery — such as avoiding bending the hip past 90 degrees, turning the knee or foot inward and crossing the leg past the middle of the body — may lead to shorter inpatient rehabilitation time and faster overall recovery, according to research presented this week at the Association of Academic Physiatrists Annual Meeting in Las Vegas.

A positive announcement for DePuy Synthes’ ATTUNE® Knee System

DePuy Synthes, part of the Johnson & Johnson Family of Companies, today announced that implant survivorship data from the 2016 Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) confirm positive early results for DePuy Synthes’ ATTUNE® Knee System. These data add to recent UK Joint Registry evidence which indicate that survivorship for the ATTUNE Knee compares favorably to other cemented knee systems in its class. In addition, recently-presented interim data on two studies suggest improved patient reported outcomes measures with the ATTUNE Knee compared to other leading knee systems.
