MicroPort® MedBot™’s SkyWalker™ Robot's Comparable Performance In China

Shanghai, China, 01 December 2023 —On November 14, One-year follow-up data from a clinical study by MicroPort® MedBot™’s SkyWalker™ in primary total knee arthroplasty (TKA) showed that the SkyWalker™ robot performed comparably to the field’s leading robot in terms of the accuracy of lower limb alignment, operation time, estimated blood loss, and results of postoperative clinical and functional knee assessment at 6-month and 1-year follow-ups. 1

Published in International Orthopaedics, a journal sponsored by the International Society of Orthopaedic Surgery and Traumatology (SICOT), this marks the first time that SkyWalker™ has conducted a head-to-head, large-sample clinical comparative study with a top international robotic product, drawing conclusions based on long-term follow-up data that validates the high surgical precision of the SkyWalker™ robot in assisting TKA, achieving favorable postoperative effectiveness. 1

TKA is considered the gold standard treatment for end-stage osteoarthritis. Accurate implant positioning, appropriate lower limb alignment reconstruction, joint line reconstruction, and gap balance restoration are critical aspects of a successful surgery. This study involved 75 patients, with 30 in the SkyWalker™ group and 45 in the control group and compared the Hip-Knee-Ankle (HKA) measures from the osteotomy plan to the actual post-operation measures in both groups. 1 No significant statistical difference was shown, and there were no significant differences in the three key indicators of operation time, blood loss, or postoperative hospital stay between the two groups. 1

Postoperative follow-up at 6 months and 1-year showed no significant differences in key metrics, including the range of motion (ROM), Knee Society Score (KSS), the Western Ontario McMaster University Osteoarthritis Index (WOMAC), and visual analogue scale (VAS). 1 All patients exhibited good incision healing, with no exudation of the nail hole, aseptic loosening of the prosthesis, periprosthetic infection, or periprosthetic fracture in the SkyWalker™ group. 1

While continuously enhancing product performance, the MicroPort® team is dedicated to providing comprehensive professional services, including ongoing reinforcement of clinical education and training, customer support, and clinical assistance.

About SkyWalker™
SkyWalker™ robot is designed for assisting in total knee arthroplasty (TKA) and total hip arthroplasty (THA) surgeries, featuring platform integration, standardization, precision, and personalization. Its preoperative planning system generates personalized prosthetic implantation plans based on patient-specific anatomical characteristics, and the robot collaboratively executes precise bone cutting and grinding during surgery. Combined with MicroPort®'s Evolution® Medial-Pivot Knee System, it emulates the knee's natural stability and movement, providing surgeons with an innovative solution for issues like instability, anterior knee pain, and functional limitations.

Currently, the SkyWalker™ robot has received certifications from China's National Medical Products Administration (NMPA), the U.S. Food and Drug Administration (FDA), the European Conformity (CE), Brazil's National Health Surveillance Agency (ANVISA), and the Australian Therapeutic Goods Administration (TGA).
