Joint Implant Surfaces

点击翻译按钮获取中文摘要

The goal of this research is to design micromachined patterned surfaces for orthopaedic implant devices that selectively cause the following types of reactions: 1) promote bone and restrict soft tissue ingrowth in critical regions; 2) enhance soft tissue growth while inhibiting bone growth; and 3) act as a barrier for soft tissue ingrowth into bone attachment areas. Combinations of the microgeometries will be tested for their ability to encourage and/or discourage site-specific tissue ingrowth and thus achieve a longer-lived hip arthroplasty device. The enhanced design of bone attachment surfaces for joint implant devices will provide an improved marketable product. The field of orthopaedic joint implants is projected to grow at 20% per year over the next 10 years with currently over 400,000 total hip arthroplasties performed annually.
