Novel total hip surgery robotic system based on self-localization and optical measurement [PDF]

arXiv, 2022
This paper presents the development and experimental evaluation of a surgical robotic system for total hip arthroplasty (THA). Although existing robotic systems used in joint replacement surgery have achieved some progresses, the robot arm must be situated accurately at the target position during operation, which depends significantly on the experience

Automated Acetabular Defect Reconstruction and Analysis for Revision Total Hip Arthroplasty: A Computational Modeling Study

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Revision total hip arthroplasty (rTHA) involving large acetabular defects is associated with high early failure rates, primarily due to cup loosening. Most acetabular defect classification systems used in surgical planning are based on planar radiographs and do not encapsulate three‐dimensional geometry and morphology of the acetabular defect.

Improved Accuracy of Component Positioning with Robotic-Assisted Unicompartmental Knee Arthroplasty: Data from a Prospective, Randomized Controlled Study.

Journal of Bone and Joint Surgery. American volume, 2016
BACKGROUND Higher revision rates have been reported in patients who have undergone unicompartmental knee arthroplasty compared with patients who have undergone total knee arthroplasty, with poor component positioning identified as a factor in implant ...

Unilateral Single Joint Arthritis Changes Joint Power in Unaffected Joints

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Pain and disability associated with arthritis of the hip, knee, or ankle is well‐documented. However, data on joint power and how arthritis in one joint affects power in that joint and in unaffected joints are limited. This study asks if arthritis in any one joint leads to (1) loss of power in that affected joint compared to the contralateral,

Hospital volume and the risk of revision in Oxford unicompartmental knee arthroplasty in the Nordic countries -an observational study of 14,496 cases

BMC Musculoskeletal Disorders, 2017
Background High procedure volume and dedication to unicompartmental knee arthroplasty (UKA) has been suggested to improve revision rates. This study aimed to quantify the annual hospital volume effect on revision risk in Oxfordu nicompartmental knee ...

Detecting total hip replacement prosthesis design on preoperative radiographs using deep convolutional neural network [PDF]

, 2019
Identifying the design of a failed implant is a key step in preoperative planning of revision total joint arthroplasty. Manual identification of the implant design from radiographic images is time consuming and prone to error. Failure to identify the implant design preoperatively can lead to increased operating room time, more complex surgery ...

Enhanced recovery after surgery for primary hip and knee arthroplasty: a review of the evidence.

British Journal of Anaesthesia, 2016
Enhanced recovery after surgery (ERAS) protocols produce significant clinical and economic benefits in a range of surgical subspecialties. There is a long tradition of applying clinical pathways to the perioperative care of joint arthroplasty patients ...

Knee Flexion Excursion Mediates the Association Between Quadriceps Stiffness and Knee Loads During the Mid‐Stance Phase of Gait

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Lower strength and higher passive stiffness of the quadriceps have been associated with a higher risk of knee osteoarthritis/pain in aging populations. It is proposed that altered quadriceps properties would cause excessive knee loads, thus contributing to knee mechanical damages, but the relevant evidence is limited.

Estimation of Pelvic Sagittal Inclination from Anteroposterior Radiograph Using Convolutional Neural Networks: Proof-of-Concept Study [PDF]

, 2019
Alignment of the bones in standing position provides useful information in surgical planning. In total hip arthroplasty (THA), pelvic sagittal inclination (PSI) angle in the standing position is an important factor in planning of cup alignment and has been estimated mainly from radiographs. Previous methods for PSI estimation used a patient-specific CT

Usage of unicompartmental knee arthroplasty.

The Bone & Joint Journal, 2018
Unicompartmental knee arthroplasty (UKA) has numerous advantages over total knee arthroplasty (TKA) and one disadvantage, the higher revision rate. The best way to minimize the revision rate is for surgeons to use UKA for at least 20% of their knee ...
