Despite the overall satisfactory results of total hip arthroplasty, post-operative complications continue to occur. To minimize these problems, computer-assisted total hip arthroplasty using navigation or robot-assisted systems is being developed. A navigation system is defined as a system that locates a position in three-dimensional space and traces the target spot, and a robot-assisted system is defined as a system that performs operations automatically with mechanical robot arms based on prior preoperative planning. Computer-assisted surgeries have shown superior results to conventional methods in implant positioning, fixation, and accurate lower extremity alignment in the limited reports available. However, computer-assisted surgeries take longer compared to conventional methods. Due to the extra time needed, the risk of postoperative infection and blood loss is considered to be higher. Nevertheless, robot-assisted system is being developed for the field of hip arthroplasty, and thus its efficacy and accuracy needs to be further investigated. Since these methods have other advantages compared to conventional methods, they are the focus of much interest.

하지 수술환자에게 적용한 로봇보조 보행훈련의 단기간 임상적 효과: 예비 연구
이하민,권중원 대한고유수용성신경근촉진법학회 2022 PNF and Movement Vol.20 No.2
Purpose: This study aimed to investigate the effect of robot-assisted gait training on the active ranges of motion, gait abilities, and biomechanical characteristics of gait in patients who underwent lower extremity surgery, and to verify the effectiveness and clinical usefulness of robot-assisted gait training. Methods: This study was conducted on 14 subjects who underwent lower extremity surgery. The subjects participated in robot-assisted gait training for 2 weeks. The active ranges of motion of the lower extremities were evaluated, and gait abilities were assessed using 10-m and 2-min walk tests. An STT Systems Inertial Measurement Unit was used to collect data on biomechanical characteristics during gait. Spatiotemporal parameters were used to measure cadence, step length, and velocity, and kinematic parameters were used to measure hip and knee joint movement during gait. Results: Significant improvements in the active ranges of motion of the hip and knee joints (flexion, extension, abduction, and adduction) and in the 10-m and 2-min walk test results were observed after robot-assisted gait training (p < 0.05). In addition, biomechanical characteristics of gait, spatiotemporal factors (cadence, step length, and velocity), and kinematic factors (gait hip flexion–extension, internal rotation–external rotation angle, and knee joint flexion–extension) were also significantly improved (p < 0.05). Conclusion: The results of this study are of clinical importance as they demonstrate that robot-assisted gait training can be used as an effective intervention method for patients who have undergone lower extremity surgery. Furthermore,the findings of this study are clinically meaningful as they expand the scope of robot-assisted gait training, which is currently mainly applied to patients with central nervous system conditions.

The Evolution of Computer-Assisted Total Hip Arthroplasty and Relevant Applications
( Jun-dong Chang ),( In-sung Kim ),( Atul M. Bhardwaj ),( Ramachandra N. Badami ) 대한고관절학회 2017 Hip and Pelvis Vol.29 No.1
In total hip arthroplasty (THA), the accurate positioning of implants is the key to achieve a good clinical outcome. Computer-assisted orthopaedic surgery (CAOS) has been developed for more accurate positioning of implants during the THA. There are passive, semi-active, and active systems in CAOS for THA. Navigation is a passive system that only provides information and guidance to the surgeon. There are 3 types of navigation: imageless navigation, computed tomography (CT)-based navigation, and fluoroscopy-based navigation. In imageless navigation system, a new method of registration without the need to register the anterior pelvic plane was introduced. CT-based navigation can be efficiently used for pelvic plane reference, the functional pelvic plane in supine which adjusts anterior pelvic plane sagittal tilt for targeting the cup orientation. Robot-assisted system can be either active or semi-active. The active robotic system performs the preparation for implant positioning as programmed preoperatively. It has been used for only femoral implant cavity preparation. Recently, program for cup positioning was additionally developed. Alternatively, for ease of surgeon acceptance, semi-active robot systems are developed. It was initially applied only for cup positioning. However, with the development of enhanced femoral workflows, this system can now be used to position both cup and stem. Though there have been substantial advancements in computer-assisted THA, its use can still be controversial at present due to the steep learning curve, intraoperative technical issues, high cost and etc. However, in the future, CAOS will certainly enable the surgeon to operate more accurately and lead to improved outcomes in THA as the technology continues to evolve rapidly.

A review of robotic‑assisted total hip arthroplasty
Kwangkyoun Kim,Seungcheol Kwon,Junhyuk Kwon,Jihyo Hwang 대한의용생체공학회 2023 Biomedical Engineering Letters (BMEL) Vol.13 No.4
Total hip arthroplasty (THA) is a successful surgical method for hip replacement but still poses challenges and risks. RoboticassistedTHA (rTHA) using new generation robotic systems has emerged to improve surgical precision and outcomes. Thepurpose of this paper is to review the literature on rTHA, with a focus on its advantages, such as individualized preoperativeplanning, intraoperative assistance, and improved accuracy in implantation, especially in complex cases. Additionally, itaims to explore the disadvantages associated with the use of rTHA, including high costs, the learning curve, and prolongedoperation time compared to manual THA (mTHA), which are critical drawbacks that require careful consideration andefforts for minimization. Some financial analyses suggest that rTHA may offer cost-effectiveness and reduced postoperativecosts compared to mTHA. While technological advancements are expected to reduce technical complications, there are stilldebates surrounding long-term outcomes. Practical limitations, such as limited availability and accessibility, also warrantattention. Although the development of rTHA shows promise, it is still in its early stages, necessitating critical evaluationand further research to ensure optimal patient benefits.
