New technology to track movement, durability of hip, knee implants

Scott Sporer

A new tracking system enables physicians to determine how a hip or knee implant is interacting with their patients' bodies through use of a radiostereometric analysis device.

The device can help physicians monitor if a replacement implant is wearing down or moving. The implant procedure, according to a Midwest Orthopaedics at Rush news release, also provides a radiostereometric analysis (RSA) registry for implants — allowing researchers to collect data on materials and designs used for hip and knee replacement prostheses.
