On October 30, 2023, Medacta (Swiss stock code: MOVE), a small giant in the Swiss orthopedic industry, announced the launch of the world's first KA-optimized knee replacement prosthesis, GMK SpheriKA, designed for total knee arthroplasty. GMK SpheriKA will make its global debut on November 2 at the 2023 Annual Meeting of the American Association of Hip and Knee Surgeons (AAHKS).

# Knee Arthroplasty Prosthesis Specifically Designed for KA Technology

Kinematic Alignment (KA) is a surgical technique used in artificial joint replacement surgery to position and place the artificial joint based on the patient's bone anatomical features and kinematic principles. The goal of this technique is to make the artificial joint move as close as possible to the biomechanical motion of a natural joint during movement.

Kinematic Alignment Technique Restores Pre-Arthritic Natural Alignment Through Anatomical Surface Reconstruction, Minimizing Ligament Release, and Achieving More Natural Knee Movement. Compared to More Traditional Techniques, This Treatment Has Proven to Improve Patient Satisfaction. As the Technique Evolves, Medacta Continues to Focus on Bringing Positive Solutions to Patients Needing Total Knee Arthroplasty.In the past few years, clinical research has emphasized that GMK Sphere is a knee implant particularly suited for kinematic alignment, with the potential to further improve patient outcomes compared to other artificial knees.

GMK SpheriKA continues the ball-and-socket design of GMK Sphere, offering patients a new type of implant that provides a more natural and stable feeling during daily activities, replicating the movement patterns of a healthy knee.Moreover, the GMK SpheriKA knee replacement prosthesis features optimized femoral coverage and patellar tracking, making it suitable for kinematic alignment surgeries. It is the first implant on the market specifically designed for KA technology.

Medacta International CEO Francesco Siccardi stated that GMK SpheriKA further strengthens Medacta's commitment to providing personalized solutions for surgeons and their patients. By collaborating with an international team of orthopedic expert physicians, the company launched this product based on the clinically proven GMK Sphere knee implant, incorporating the fundamental principles of kinematic alignment to ensure that the implant used during surgery adapts to each patient’s unique anatomy.

Stephen Howell, Ph.D., a pioneer in kinematic alignment techniques, expressed his delight in offering patients the GMK SpheriKA implant, which is designed to provide personalized options that meet the unique anatomical and patellofemoral kinematic requirements of each patient, thereby providing a more natural knee joint for quicker restoration of athletic function and daily activities.

# About MyKA Kinematic Alignment Platform

MyKA is Medacta's Kinematic Alignment Platform. This product is based on the kinematic alignment surgical approach and serves as an alternative to traditional mechanical alignment in TKR (Total Knee Replacement). Kinematic alignment technology aims to restore normal knee function by reconstructing the femoral and tibial articular surfaces to their pre-arthritic or normal state. This method seeks to maximize patient satisfaction, restore natural joint function, and minimize damage to surrounding tissues and ligaments.

The MyKA platform is enhanced with cutting-edge technologies, such as the dedicated planning solution for MyKnee 3D-printed patient-matched guides and the NextAR Knee augmented reality surgical application (which provides unique real-time data to effectively complement the surgical workflow). Both NextAR Knee and MyKnee are part of the MySolutions personalized ecosystem, an advanced network of digital solutions from Medacta designed to improve patient outcomes and increase healthcare efficiency.

# About Medacta

Medacta (SIX: MOVE), a publicly listed company headquartered in Switzerland, focuses on the orthopedic sector, particularly in joint replacement, spinal surgery, and sports medicine. It utilizes the AMIS® (a minimally invasive technique) system for hip replacement surgeries and the MyKnee® patient-matched technology for total knee replacements. AMIS has been used in over 50,000 hip surgeries worldwide.

Medacta, founded in Switzerland in 1999, is now an international orthopedic company. In 2021, Medacta's total revenue reached 363.1 million euros (2.538 billion RMB), increasing by 21.4% compared to 2020. Additionally, Medacta's NextAR Augmented Reality (AR) surgical platform obtained registration certification, applicable for knee, shoulder, and spine procedures, and successfully performed reverse shoulder arthroplasty using NextAR Shoulder in July 2021. Furthermore, after receiving U.S. FDA approval and CE marking, Medacta officially began commercializing its 3D Femoral Conical Wedge for revision knee arthroplasty.

Medacta is a pioneer in developing new products based on minimally invasive surgical techniques, particularly its Anterior Minimally Invasive Surgery ("AMIS") technology for hip replacement. Leveraging its orthopedic expertise and deep understanding of human anatomy, Medacta has also developed the advanced "MySolutions" technology. This technology provides highly personalized preoperative planning and implant placement methods for surgeons through the creation of sophisticated personalized kinematic models and 3D planning tools for the hip, which can also be applied to knee, shoulder, and spine surgeries.
