Each year, more than 1.2 million American and European patients lose their meniscus due to injury. Many incidents result from sports activities, such as soccer and other contact sports. More than 200,000 patients are left with such a painful knee that they can no longer play sports and sometimes even have to stop working. Only 5 percent of these patients benefit from surgery. The pain of the remaining patients can sometimes be relieved temporarily, but no permanent solution is available for them.

A meniscal prosthesis can restore shock absorption in the knee to relieve pain and increase the patient's quality of life. ATRO Medical is currently clinically evaluating a standard implant, which is available in five sizes. The next step is a more personalized solution, based on the patient's own anatomy. With the latest developments in imaging techniques, artificial intelligence and 3D printing, this option is actually becoming possible.

The 3PPP project should provide evidence that AI-based meniscus modeling of MRI images, including the development of the surgical procedure and tools needed, does indeed work (proof of principle). All aspects will be verified in the testing facilities of the Orthopaedic Research Lab of the Department of Orthopedics at the Radboudumc, bringing this technology close to clinical introduction. Maarten van der Zanden, CIO of ATRO Medical: "We are very pleased with the expansion of our collaboration and with the opportunity to discover how AI can be used for knee patients with meniscus problems."

A study of ATRO Medical's first artificial meniscus is currently underway in the Netherlands with 14 patients in three clinics. 3PPP is a two-year SME project, co-funded by Health~Holland, Top Sector Life Sciences & Health, to stimulate public-private partnerships.

The Orthopaedic Research Laboratory (ORL) of Radboudumc starts a new project with ATRO Medical: 3D-Printed PCU meniscus Prosthesis (3PPP). 3PPP combines the latest developments in sports medicine with the strength of AI. The durable meniscus prosthesis of ATRO Medical will be designed in 3D based on artificial intelligence, developed by the Orthopaedic Research Lab. Thanks to this technology, a scan of the healthy meniscus in one leg can be used to create a meniscus solution for the affected leg. In this way, the side with a lacking meniscus causing severe knee pain can receive a new shock absorber, molded to the individual patient.

Radboudumc and ATRO Medical start research on AI-generated artificial meniscus.

Introduction to ATRO Medical

Introduction to ATRO Medical - The Meniscus Company

The US Food & Drug Administration identifies the Trammpolin® meniscus prosthesis as a unique and potentially more effective treatment for knee osteoarthritis patients with a deficient meniscus. At the moment there is no effective treatment available for a large group of these patients.

CEO Jan Hunik is excited to receive the Breakthrough Device Designation: “We still have quite some work to do before we can access the US market and obtain the CE mark for the European market. This designation endorses our conviction that the Trammpolin meniscus prosthesis can make an important impact on the lives of patients suffering from chronic knee pain. We look forward to the more intense collaboration with the FDA and are confident that this will expedite our US timelines.”

The goal of the Breakthrough Device Designation program is to provide patients and their health care providers with timely access to effective medical innovations. The designation ensures a predictable and timely assessment by the FDA. The Trammpolin meniscus prosthesis will have priority in upcoming FDA reviews. The FDA will also give more transparency with respect to the required data for market access of ATRO Medical’s meniscus implant.

Knee Osteoarthritis (KOA) is an irreversibly debilitating disease and is one of the leading causes of disability in Europe and the US. The Trammpolin meniscus prosthesis is a durable anatomically shaped implant that aims to reduce knee pain and restore mobility. Trammpolin is currently being assessed in a first clinical study in the Netherlands. A next study will most likely include clinics in other European countries as well as the United States. ATRO Medical is largely financed by venture capital and is expected to organize a next investment round (Series B) in 2021 to further accelerate its path to the EU and US market.

**Trammpolin® is nowadays known as Artimis®

Dutch medical innovations are rarely granted the Breakthrough Designation by the FDA. Startup ATRO Medical from Nijmegen is the new kid on the block in orthopedics. This week their Trammpolin® meniscus prosthesis (nowadays known as Artimis®), designed to treat chronic knee pain, received the Breakthrough Device Designation from the FDA. The designation demonstrates the innovation potential of this implant and expedites US market access by receiving a priority treatment at the FDA.

Dutch meniscus prosthesis receives FDA Breakthrough Device Designation

Knee osteoarthritis is one of the leading causes of disability worldwide. Loss of meniscus tissue in the younger years can accelerate this disease, leading to complaints such as severe chronic knee pain, stiffness and immobility. Many patients finally end up with a total knee replacement. The Dutch orthopedic startup ATRO Medical has the mission to create a solution for the long, painful period before total knee replacement.

A durable meniscus prosthesis can serve as a new damper in the knee, reducing bone to bone impacts and as such relief pain in the knee joint. An implant for the inner side of the knee joint is currently in clinical research after ten years of development. However, a solution for the outer knee compartment is still missing. Since forty percentage of complaints are apparent in this so- called lateral compartment, many patients would benefit from it.

The consortium of ATRO Medical, the Swiss company Samaplast and the Orthopaedic Research Laboratory (ORL) of the Radboud university medical center receives over € 800,000 EUROSTARS funding as part of a total investment of € 2 million to rapidly change this situation. The team is committed to develop a new meniscus prosthesis for the outer knee compartment and have it ready for a clinical trial within just two years’ time. Both the durable solution for the outer knee compartment and the short development time would be unique in the orthopedic society.

The ORL has been involved in meniscus research for many years as biomechanical expert and was part of the team developing the IP for this innovation. Samaplast is specialized in injection molding of high-precision and medical grade products out of plastic. ATRO Medical is a spin-off from the Radboud university medical center and DSM Biomedical and focuses on the design of durable meniscus prostheses. These three parties together have the required expertise to bring the new meniscus prosthesis to life with EUROSTARS funding.

EUROSTARS supports international innovative projects led by R&D performing SMEs such as ATRO Medical, that help improve the daily lives of people around the world. This EU program aims to bring increased value to the economy, higher growth and more job opportunities.

ATRO Medical is a spin-out from DSM and Radboud University Medical Center with offices in Nijmegen and Uden (NL). The company builds on the knowledge developed in the Public-Private Collaboration BioMedical Materials (BMM) that started in 2010 with a consortium of universities, companies and financial support from the Dutch government. The collaboration between the clinical, biomechanical and polymer experts has led to the development of the Trammpolin® Meniscus Prosthesis (nowadays known as Artimis™), and the foundation of ATRO Medical in 2016.

An international consortium led by the Dutch med-tech startup ATRO Medical receives over € 800,000 EUROSTARS funding to address an unmet need for Knee Osteoarthritis patients. These patients often suffer from cartilage degradation related to a dysfunctional meniscus. Based on previous research, the consortium will develop a durable meniscus prosthesis for the outer knee compartment to relief pain and restore mobility. This would change the life of thousands of osteoarthritis patients.

EUROSTARS grants funding for first lateral meniscus prosthesis

What a great recognition for our team of the potential benefit that our meniscus prosthesis may have for Veterans. The incidence of knee osteoarthritis is known to be 10 times higher under military personnel compared to civilians. This is highly correlated to meniscus damage. And almost 20% of those who need surgical meniscus repair will leave the army within 2.5 years.

We would be honored if our Trammpolin® Meniscus Prosthesis could play a part in providing pain relief for these veterans. Besides the recognition, this award comes with grant funding, which will be spent on accelerating the development of the lateral meniscus prosthesis.

The lateral (outside) compartment of the knee joint is known for its’ fast cartilage degradation in a meniscus- deficient knee. It is of utmost importance to provide an early surgical solution for this lateral side since the severity of complaints and disease related health costs increase with ongoing cartilage degradation.

The Dutch startup ATRO Medical is entirely focused on creating a durable solution for patients suffering from the post-meniscectomy pain syndrome. Their meniscus prosthesis under development has already received FDA breakthrough device designation, the EU Seal of Excellence and the MedTech Innovator finalist award by AdvaMed. Their medial prosthesis is currently under investigation in a prospective clinical study in the Netherlands.

10 years ago, the Dutch Arthritis Society has invested in new materials for the research done by Radboud University Medical Center. Which changed the positioning of the health fund together with diverse universities and royal DSM to the upfront of new approach of Polycarbonate Urethan. Which the startup ATRO Medical originated in 2017, located on the Novio Tech campus in Nijmegen, The Netherlands. From there on out the accumulated scientifical knowledge was further developed into an applicable prothesis. 

Jan Hunik, CEO of ATRO Medical: ‘’ Since 2019 the meniscus prosthesis has been used in clinical study with the first patients. The second clinical trial starts in 2021 with a couple of Dutch hospitals. The trials must lead to CE marking of the unique prosthesis especially due to the knowledge provided by Dutch Arthritis Society, which makes this innovation available for European patients.’’

The artificial meniscus prosthesis is meant for patients with knee arthritis. With many of these patients their meniscus was partially removed, or they’re experiencing chronic pain due to knee wear. The meniscus prosthesis offers this group of patients an alternative for the current policies such as pain medication, physiotherapy and the wait to being considered for a total knee replacement. 

Corné Baatenburg de Jong of The Dutch Arthritis Society explains: ‘’It is nice to see that a development throughout the years has eventually been integrated by a team such the one of ATRO Medical and turned it into a new procedure for the patient. They work hard to improve the quality of knee arthritis patients with the use of the meniscus prosthesis. During the implementation, we as organization can support this. We know the way through the path. And thanks to the big patient participation at The Dutch Arthritis Society, we can make sure that their voices are heard. This guarantees that the development fits the patients’ expectations.  

ATRO Medical is a spin-off of DSM & Radboud University Medical Center with offices in Nijmegen & Uden (NL). The startup builds further on knowledge from the public-privates collaboration BioMedical Materials (BMM), started in 2010 as a consortium of universities and companies with financial support of the Dutch government. The collaboration between clinical, biomechanical & polymer-experts which led to development of the Meniscus Prosthesis and establishment of ATRO Medical in 2016. The first clinical study started in 2019. More information can be found on www.atromedical.com

The EIC Accelerator program is the most important instrument of the European Commission to support promising healthcare innovations. The program aims to develop and scale up game changing innovations. The EIC Accelerator grant provides access to an investment by the EIC Fund, coordinated by the European Commission and particularly used to bridge the funding gap between market entry and scale up.

The € 2.5 million grant will be spent on accelerating pre-clinical testing of the meniscus prostheses, on health economic analyses and international clinical studies. All efforts combined will fast-track the implementation of this Dutch healthcare innovation. ATRO Medical is the first company worldwide to have solutions for both the inner and outer meniscus close to the clinical stage.

Thousands of patients suffering from chronic knee pain are waiting for these solutions. Their meniscus has been removed as a result of an earlier trauma and they have developed the so-called post-meniscectomy pain syndrome. Orthopedic surgeon and Chief Medical Officer Dr. Tony van Tienen explains, “I see many patients with chronic knee pain in my clinical practice. Most of them are too young for a total knee replacement. However, they should be able to go to work, go shopping or simply walk their dog without constantly being bothered by an aching knee. Our artificial meniscus aims to relieve that pain. Pain free mobility, that is what we strive for.”

ATRO Medical has already received several international recognitions for their thought-leading work like FDA breakthrough device designation, Eurostars funding and the Johnson & Johnson Quickfire award. In the next few years, the company will leverage these endorsements and funds to significantly expand their clinical evidence and achieve market registration. Together with partners like the Dutch Arthritis Society, the Orthopaedic Research Laboratory and international clinics such as the Sint Maartenskliniek, Mayo Clinic and Sporthopaedicum Berlin they are confident to succeed.

The European Commission grants € 2.5 million to ATRO Medical for the accelerated development of their artificial meniscus. The Dutch startup works on the first anatomical meniscus prostheses for patients with chronic knee pain. Their ground-breaking innovation continues to attract international attention, paving the way towards full-scale healthcare implementation.
