Triathlon Cruciate Retaining (CR) Outcomes Study

2014-08-27 03:20:04 | BioPortfolio


The purpose of this study is to evaluate the clinical outcomes (range of motion, pain, function, radiographic stability, and health related quality of life) of patients receiving the Triathlon Cruciate Retaining (CR) Total Knee System. These outcomes will be evaluated using pre-operative scores comparing them to post-operative scores in addition to being compared with a control group. The control group is Scorpio CR.


The Triathlon Cruciate Retaining (CR) Total Knee System components are for cemented use in total knee arthroplasty for painful, disabling joint disease of the knee resulting from non-inflammatory degenerative joint disease (including osteoarthritis, traumatic arthritis or avascular necrosis) or rheumatoid arthritis (excluded from this study according to protocol). The components are designed to improve range of motion (ROM) and stability. The Triathlon Cruciate Retaining (CR) Total Knee System is also designed to provide better anatomic fit and efficiency in the operating room. This study serves to demonstrate that subjects have reduced pain, increased ROM and improved stability following implantation with the Triathlon Cruciate Retaining (CR) Total Knee System.

A vinyl polymer made from ethylene. It can be branched or linear. Branched or low-density polyethylene is tough and pliable but not to the same degree as linear polyethylene. Linear or high-density polyethylene has a greater hardness and tensile strength. Polyethylene is used in a variety of products, including implants and prostheses.
