Prestigious Klee Family Foundation Prize 2020 Awarded for Outstanding Scientific Work Identifying Patient-Specific Approach as Better Way to Optimize Knee Implant Design

Dr. Malte Asseln awarded annual prize by German Society for Biomedical Engineering at the VDE Association and the Klee Family Foundation for his scientific computer-and-image-based workflow to optimize knee implant design

BILLERICA, Mass., May 21, 2020 (GLOBE NEWSWIRE) — Conformis, Inc. (NASDAQ: CFMS) congratulates Dr. Malte Asseln for winning the prestigious Klee Prize 2020 for his dissertation and computer-and-image-based workflow on the optimization of knee implant design – “Morphological and Functional Analysis of the Knee Joint for Implant Design Optimization.”

As reported in Medizin and Technik on May 6, 2020, Dr. Asseln’s results show that more knee implant sizes are required than are currently manufactured by off-the-shelf knee implant manufacturers, so patient-specific or better-tailored solutions are a promising approach to increase the 70 percent industry-wide patient satisfaction with artificial knee joints that he has observed.

Dr. Asseln concluded that one of the main drivers of the 30 percent industry-wide dissatisfaction with knee implants is the design of standard implants, which takes insufficient account of patient-specific biomechanics.

“I am always pleased to see third-party scientific research validate my belief in the inherent superiority of the patient-specific knee implant design approach over standard, off-the-shelf knee design to eliminate joint pain relief,” said Mark Augusti, President and CEO of Conformis, Inc. “Congratulations to Dr. Asseln!”

As part of his analysis, Dr. Asseln developed methods for generating parameterized surface models of articular surfaces to enable systematic shape variations. He also developed a patient-specific biomechanical simulation model of the lower extremity and an experimental bench test to analyze the relationship between design parameters and knee function. Further, he used the outer geometric dimensions of the knee joint to calculate a sufficient number of implant sizes.

For his morphological analysis of the natural knee joint, Dr. Asseln built up a comprehensive database with geometric features and evaluated them. He used a database of 831 patient records, from which 59 geometric features were extracted.

Most traits showed statistically significant gender differences. After Dr. Asseln classified and normalized the features according to the direction of their measurement (i.e. width and depth), it became apparent that, after normalization, there were large inter-individual deviations, which indicates that patient-specific design solutions would be the only way to accommodate for these differences.
