SUN Clinical Study Information:

Meniscus Injury

The meniscus is a tissue pad located between the thigh and shin bones and each knee has two menisci, lateral and medial.  These crescent-shaped pads distribute the load between upper body and lower leg and are highly vulnerable to tearing, both from physical activity and excess weight.  Millions of Americans visit physicians as a result of meniscus tears and many end up having a partial meniscectomy, which can alleviate pain but puts them at high risk for arthritis and future knee replacement. In addition, many people still suffer from continued knee pain that can seriously affect their daily lives.  Once damaged, the meniscus has a very limited potential to heal itself.  

Investigational Treatment: NUsurface® Meniscus Implant

The NUsurface® Meniscus Implant (pronounced “new surface”) is an investigational treatment for patients with persistent knee pain following medial (inner) meniscus surgery. It is made from medical grade plastic and, as a result of its unique materials, composite structure and design, does not require fixation to bone or soft tissues. The NUsurface Meniscus Implant mimics the function of the natural meniscus and redistributes loads transmitted across the knee joint. Clinical trials are underway in the U.S., Europe and Israel to verify the safety and effectiveness of the NUsurface Meniscus Implant.  It has been used in Europe under CE Mark since 2008 and Israel since 2011.

Study Overview

The SUN (Safety Using NUsurface) clinical trial is assessing the safety and effectiveness of the NUsurface Meniscus Implant in restoring function similar to that of a natural, healthy meniscus. All participants who meet study requirements and agree to enter the trial are offered the NUsurface Meniscus Implant as treatment.

The study lasts for 60 months following initial treatment.  During this period, patients will be seen or contacted by their doctor at 1½, 3, 6, 12, 24, 36 and 60 months after beginning treatment to conduct a physical examination or ask patients to complete a questionnaire describing how they feel about their knee and their quality of life.

Procedure and Recovery

The NUsurface Meniscus Implant is inserted into the knee joint through a small incision. Participants go home after a short stay in the hospital following the operation. After surgery, they undergo a six-week rehabilitation program.


To be eligible for the study, participants must:

•        Be between the ages of 30 and 75

•        Have pain after medial meniscus surgery

·         Have had meniscus surgery at least six months ago

Study Sites

As part of the process to gain regulatory approval in the U.S., the SUN study will enroll approximately 120 patients at up to 20 locations. The following orthopedic centers are or will soon be recruiting patients, and additional sites will be added as needed:

·         Tom Carter, MD – TOCA, The Orthopedic Clinic Association (Phoenix, Arizona)

·         Peter Kurzweil, MD – Memorial Orthopaedic Surgical Group (Long Beach, California)

·         William Montgomery, MD – St Mary’s Medical Center (San Francisco, California)

·         Eric McCarty, MD – Colorado University Sports Medicine (Boulder, Colorado)

·         Wayne Gersoff, MD – Advanced Orthopedics & Sports Medicine Specialists (Denver, Colorado)

·         Robert Easton, MD – Baton Rouge Orthopaedic Clinic (Baton Rouge, Louisiana)

·         Deryk Jones, MD – Ochsner Sports Medicine Institute (New Orleans, Louisiana)

·         John Greenleaf, MD – Oregon Sports Medicine (Portland, Oregon)

·         Joseph Berman, MD – Baylor Orthopedic and Spine Hospital (Arlington, Texas)

·         Andrew Cooper, MD – Salt Lake Regional Medical Center (Salt Lake City, Utah)
