CUVIS-joint

Optimal surgical planning and precise cutting

CUVIS-joint

is a cutting-edge surgical robot system that improves the completion of artificial joint surgery with optimal surgical planning and precise cutting.

With optimal tracking sensors and self-developed surgical planning CUVIS-joint helps patients that are in need of artificial knee surgery.

Why CUVIS-joint is good?

  • Point. 01

    Surgical Planning & Execution Based on 3D CT Analysis

    Surgical Planning & Execution Based on 3D CT Analysis

    Precisely analyzes the patient's bone morphology based on pre-operative 3D CT images and accurately predicts femoral (98.9%) and tibial (100%) implant sizes.1

    Precise Bone Resection

    The robotic arm performs precise bone resection within a 1mm error margin (98% rate) within the planned range.1

    Sophisticated Angle Control

    Maintains the cutting angle error (RMS) below 1 degree, ensuring that simulation results are perfectly reproduced in the actual operating room.2

  • Point. 02

    Optimal Soft Tissue Balance and Alignment

    Real-time Gap Balancing

    Checks and adjusts the gap balancing of the medial and lateral knee in real-time during surgery to support achieving ideal balance.3 4

    Functional Alignment

    Goes beyond simply straightening the bone by identifying the optimal rotational alignment reflecting the patient's specific rotational axes (TEA, PCA).5 6

    Joint Line Restoration & Soft Tissue Preservation

    Restores the anatomical position by maintaining pre- to post-operative joint line height changes at an average level of 1.65mm, and reduces the frequency of unnecessary soft tissue releases.7 8

  • Point. 03

    Safety and Versatility

    Surgical Safety

    Recorded 0 cases of major surgical complications, such as nerve and blood vessel damage, in a large-scale study of 500 cases at a single institution.9 Additionally, the safety of pin insertion sites is secured through methods such as intra-incisional pin fixation.10 11

    Wide Range of Application

    Stable surgery is possible without complications even in morbidly obese patients where surgical field visibility is difficult,12 and accurate correction angles are achieved even in patients with high-difficulty deformities such as severe valgus knees.13

  • Point. 04

    Pain Reduction and Functional Recovery

    Initial Pain Relief

    Reduces tissue damage through precise resection, aiding in the reduction of pain scores (VAS) and analgesic consumption in the early post-operative period (Days 1-2). 14

    Verified Functional Recovery

    Demonstrated excellent clinical results in OKS(Oxford Knee Score) and FJS(Forgotten Joint Score) 1 year after surgery.15 16
