Introduction to Prosthetic Limbs [PDF]
, 2015 Approximately 2 million people in the Unites States alone have had an amputation, and many of these people use a prosthetic limb daily. The prosthetic limb, which began as a primitive device, is now a highly sophisticated piece of technology.

A circumferentially flanged tibial tray minimizes bone-tray shear micromotion [PDF]
, 2005 Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening.

PLoS ONE, 2015 Background Periprosthetic joint infection (PJI) is a serious complication of total knee arthroplasty. Two-stage revision is the most widely used technique and considered as the most effective for treating periprosthetic knee infection.

The Markov model of a dynamic system based on experimental data for control problems of bionic prostheses [PDF]
arXiv, 2022 This article is devoted to a prediction of gait kinematics based on the Markov chains in the delay space. We use hypercubic grid in the delay space of angles in the sagittal plane in the knee and hip joints to construct Markov states. Our experimental signal (obtained from the telemetry of the prosthesis) provides transition probabilities.

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose After unsatisfactory results in a first‐in‐human clinical investigation with an anatomically shaped medial meniscus prosthesis, the prosthesis and its fixation technique were altered. This interim analysis of a prospective single‐arm clinical investigation aims to evaluate safety and clinical performance in a first‐in‐human study with ...

Orthopaedic Surgery, Volume 15, Issue 1, Page 162-168, January 2023., 2023 The expandable devices were made up of titanium alloy. This technique overcomes discrepancy and reduces risk of invalid gears. Objective Survival and reconstruction in osteosarcoma is quite challenging. The study aimed to investigate the prognosis in patients treated with neoadjuvant chemotherapy and determine the clinical outcomes of expandable ...

Towards a working methodology for using total hip and knee joint replacements to support identification [PDF]
, 2015 Hip and knee prostheses have occasionally been used to support identification of unknown persons along with other medical devices and implants. This paper looks at the specific issues around using hip and knee implants, suggesting a working methodology ...

How should we assess the mechanical properties of lower-limb prosthesis technology used in elite sport?: An initial investigation [PDF]
, 2013 Despite recent controversy, it is not yet formally recognised how lower-limb prosthesis should be assessed for their performance. To assist in this process, experiments are undertaken to investigate the linearity, stiffness and assessment of feet based ...

Trip Recovery in Lower-Limb Prostheses using Reachable Sets of Predicted Human Motion [PDF]
arXiv, 2020 People with lower-limb loss, the majority of which use passive prostheses, exhibit a high incidence of falls each year. Powered lower-limb prostheses have the potential to reduce fall rates by actively helping the user recover from a stumble, but the unpredictability of the human response makes it difficult to design controllers that ensure a ...

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Unicondylar arthroplasty was performed using robotic medial unicompartmental knee arthroplasty (R‐mUKA) and gap‐balancing instrumentation. Our hypothesis was that robotic unicondylar knee arthroplasty accurately restores component positioning and lower limb alignment when compared to preoperative planning with actual implantation ...
