MicroPort Orthopedics Inc., a medical device company that develops and manufactures cutting edge joint replacement implants designed to help patients achieve full function faster, announced that The Knee has published a study evaluating long-term clinical and radiographic outcomes of the Medial-Pivot Knee System. The results demonstrate excellent clinical outcomes for both satisfaction (95%) and survivorship (98.8%) at 17 years with patients noting a great sense of stability and comfort during regular activities.1

It has been reported that approximately 20% of patients are not satisfied with the outcome of their total knee replacement as a result of residual pain and functional issues often attributed to implant design.2 MicroPort’s Medial-Pivot Knee System is uniquely designed to restore stability and normal knee kinematics to deliver reproducible outcomes that can improve function and drive patient satisfaction.

“I am in my third year of using the Evolution® Medial-Pivot Knee System and this publication validates the results that I have seen in my practice,” says David Backstein, MD, MEd, FRCSC, Head of Orthopaedic Surgery at Mount Sinai Hospital in Toronto, Ontario. “In my experience, the functional outcomes for patients treated with this system have certainly been superior than the systems I’ve used in the past and patients have fewer complaints. When I see them at six or eight weeks follow-up, they’re at a different stage of recovery than I was seeing previously with traditional implant designs. I’ve been exceptionally happy with the results and feel comfortable knowing I am implanting a prosthesis with 98.8% survivorship at 17 years.”

The paper, titled, A Long Term Clinical Outcome of the Medial Pivot Knee Arthroplasty System was authored by George A Macheras et al. from the “KAT” General Hospital, Athens, Greece. In the study, 325 patients with knee osteoarthritis underwent Total Knee Arthroplasty (TKA) using the Medial-Pivot prosthesis. All patients showed a statistically significant improvement in the Knee Society clinical rating system, Western Ontario and McMaster Universities Osteoarthritis Index, and Oxford knee score. The majority of patients (94%) were able to perform age-appropriate activities with average knee flexion of 120° and 98% of patients reported relief of pain to be excellent, very good or good. Additionally, survival analysis showed a cumulative success rate of 98.8% at 17 years.
