Implantable Knee Spring Successfully Reduces Pain

For the millions of patients with mild to moderate knee osteoarthritis (wear), an innovative advance in knee surgery continues to demonstrate success according to patient follow up data from clinical trials. The KineSpring System is an implantable medical spring that works by unloading the weight on the diseased knee joint, without making any changes to the anatomy.

Follow-up data from 100 patients pooled from multiple clinical studies showed that the KineSpring System significantly reduced osteoarthritis pain and significantly improved knee function by over 80% for patients beyond the 3 year follow-up time point. Data has now been collected from patients up to 4 years following the procedure. Typically patients had a short hospital stay (less than 2 days), were walking unaided within 2 weeks and possessed full range of movement by 3 months.

“My personal clinical experience with the KineSpring System demonstrates that in carefully selected patients with moderate medial compartment arthritis, it has provided relief of arthritic pain for up to 2 years so far,” notes Rhys Williams, consultant orthopaedic surgeon, Vale Healthcare, and Cardiff and Vale NHS Trust.

“Many patients with osteoarthritis, who are not candidates for joint replacement surgery due to age or activity levels, suffer from pain and a decreased quality of life,” explains Nick London, consultant knee surgeon, Yorkshire Knee Clinic and Harrogate and District NHS Foundation Trust. “By cushioning the knee from excessive load, the KineSpring System helps alleviate the pain associated with osteoarthritis allowing the patient to return to a more regular lifestyle, and delaying the need for knee replacement surgery.”

London will present information on the KineSpring System and its entry into the UK medical system today at the London Knee meeting, at the Queen Elizabeth II Conference Centre.

“There is a significant clinical treatment need for patients suffering from knee osteoarthritis but who are not candidates for knee replacement due to age, activity, or disinclination,” notes Kevin Sidow, president and CEO of Moximed. “The KineSpring System addresses this need and has been benefiting patients in Australia and several European countries, including the UK, Germany, Belgium, France, and Italy. Moximed intends to increase the number of trained orthopaedic surgeons and significantly expand patient access to this revolutionary new technology for the remainder of 2012 and beyond.”
