Skive and Severance Research Team’s Knee Implant Analysis Study Approved for Publication in International Journal BJR

Skive Co., Ltd., a digital healthcare and medical device company specializing in orthopedics, announced that a joint study on total knee arthroplasty (TKA), conducted with research teams led by Professor Park Junyoung of Yonsei University Yongin Severance Hospital and Professor Cho Byungwoo of Gangnam Severance Hospital, has received final publication approval from 'Bone & Joint Research (BJR)', an internationally renowned journal in the field of orthopedics.

BJR holds a Q1 ranking, placing in the top 5% of journals in the field of orthopedics with an Impact Factor of 5.1 according to Web of Science. It is recognized as a highly influential international academic journal in orthopedics. The acceptance of this paper is significant as it demonstrates that Skive’s biomechanics-based analysis technology has passed rigorous academic scrutiny, securing scholarly credibility on a global stage.

This study aimed to analyze and reduce issues such as stress shielding and bone resorption that can occur after total knee arthroplasty (TKA). The research team used Skive’s analysis technology to classify the degree of medial tibial sclerosis into four stages, and by combining four different tray and keel implant designs with two rotational alignment techniques, conducted finite element analysis (FEA) on a total of 32 conditions.

The results showed that as the patient’s level of bone sclerosis increased, the risk of bone resorption also tended to rise. Among implant structures, the keel design emerged as the most significant variable influencing load distribution and bone preservation. In contrast, differences between rotational alignment techniques—such as the maximum coverage method and the Insall method—were found to be relatively limited. Based on these findings, the researchers confirmed that selecting an implant tailored to the patient’s bone condition has a critical impact on surgical outcomes.

Professor Park Junyoung, the first author of the study, explained, “It is clinically meaningful that we were able to mechanically explain the risk of bone resorption by analyzing the unique tibial sclerosis characteristics of each patient in conjunction with implant design and surgical variables.” Co-corresponding author Professor Cho Byungwoo stated, “Through quantitative modeling, we have established a foundation for clinicians to develop more evidence-based surgical plans.”

Skive plans to incorporate the results of this research into its integrated medical imaging and biomechanics analysis solution. The company stated that, through this integration, it aims to more precisely predict risks that may arise during orthopedic surgery and to advance precision medicine technologies that support the development of patient-specific surgical plans.
