New knee replacement causes 96% less wear

A new knee replacement technology results in up to 96 per cent less wear than competing implants, according to the results of laboratory tests.

Stryker Orthopaedics, which claims to distribute the largest range of orthopaedic products from any one company operating in the UK, has unveiled test results of its latest innovation, which combines two of its more recent implants in a new knee system.

The new implant combines the company's Triathlon Knee System with its X3 cross-linked polythene, allowing both greater longevity of the implant and a smoother motion.

Wear is one of the major causes of implant failure and, by reducing this, the company says that it is therefore improving the longevity of its implants.

Mike Mogul, president of Stryker Orthopaedics, commented that the test results demonstrated the company's commitment to developing longer-lasting implants.

"Today's knee replacement patient is younger and more active than the patients of a generation ago," Mr Mogul explained.

"And for them, the longevity of the implant is a fundamental concern.

"By focussing on wear reduction technologies, Stryker believes we can not only relieve the suffering of these patients, but allow them to continue their lifestyles while decreasing their worry about the life of their implants."

The implants will be available in a variety of different sizes and are designed to suit the particular anatomical requirements of both male and female patients.

A recent survey, commissioned by Stryker Corporation, found that longevity of implants is one of the most fundamental concerns for patients considering knee replacement surgery.

However, studies have shown that knee replacements still function well after 15 years in 90 to 95 per cent of patients and the majority of implants last for over 20 years.
