Quasi Optimal Gait of a Biped Robot with a Rolling Knee Kinematic [PDF]

, 2011
In this paper, we address the problem of optimization of trajectories for a new class of biped robot. The knees of this biped are similar as the anthropomorphic one and have a rolling contact between the femur and the tibia.

Knee pain, knee osteoarthritis, and the risk of fracture [PDF]

Arthritis Care & Research, 2006
Abstract Objective Patients with osteoarthritis (OA) have increased bone mineral density; however, the association between knee OA and fracture is controversial. Few data exist on the association between knee pain and fracture.

Above-Knee versus Below-Knee Stockings in Total Knee Arthroplasty [PDF]

The Annals of The Royal College of Surgeons of England, 2006
INTRODUCTION Graduated compression stockings are frequently used following arthroplasty surgery for deep vein thrombosis (DVT) prophylaxis. There are often strongly held beliefs regarding whether below-knee or above-knee stockings should be used in total knee joint replacement.

"Knees" in lithium-ion battery aging trajectories [PDF]

, 2022
Lithium-ion batteries can last many years but sometimes exhibit rapid, nonlinear degradation that severely limits battery lifetime. In this work, we review prior work on "knees" in lithium-ion battery aging trajectories.

Knee mechanisms for through-knee prostheses [PDF]

Prosthetics & Orthotics International, 1983
The most widely used knee mechanisms for through-knee amputees can be characterized as three principal types of design. These types are metal side bars with heavy duty joints, conventional knee mechanisms for above-knee amputees and special polycentric linkage mechanisms for through-knee amputees. An investigation in Sweden in 1979 showed that over 50%

Significant reduction of patellar height affected lower clinical outcomes and knee flexion over five-year follow-up after total knee arthroplasty

Bone & Joint Open, 2021
Aims: This study aimed to investigate the relationship between changes in patellar height and clinical outcomes at a mean follow-up of 7.7 years (5 to 10) after fixed-bearing posterior-stabilized total knee arthroplasty (PS-TKA).

Summary of 6 biclusters in overall data (all knees).

, 2022
This heatmap shows all included variables on the y-axis, and knees on the x-axis. Biclusters are indicated across the top by number. The color scale indicates the direction of the variable on a standardized scale.

Diagnosis of periprosthetic joint infections in patients who have rheumatoid arthritis: application of routine serological and synovial fluid indexes

Bone & Joint Research, 2023
Aims: To investigate the optimal thresholds and diagnostic efficacy of commonly used serological and synovial fluid detection indexes for diagnosing periprosthetic joint infection (PJI) in patients who have rheumatoid arthritis (RA).
