BACKGROUND After unilateral total knee arthroplasty, frontal plane loading patterns on the operated knee remain pathological in the long term, but it is unclear how they change in the early postoperative period. Additionally, researchers have suggested that the non-operated knee bears greater frontal plane loads postoperatively, but this effect is unclear. The objective of the present study was...

Knee joint is the most important and complex structure in human lower limbs. It a nonlinear, time-varying strong coupling system. In this paper, mechanical of prosthetic knee built, parallel control CMAC PID algorithm introduced to establish model. Through simulation analysis, it found that CMAC-PID compared with traditional can improve real-time accuracy Therefore, optimize effect knee.

Background: The ultimate goal of the treatment of infectious knee arthritis is to protect the articular cartilage fromadverse effects of infection. Treatment, however, is not always hundred percent successful and has a 12% failurerate. Persistent infection is more likely to happen in elderly patients and those with underlying joint diseases,particularly osteoarthritis. Eradica...

This study aims to determine the relationship between quadriceps angle, anthropometric measurements and muscle strength. The angle (Q angle) consider clinically as a very important parameter which displays biomechanical effect of on knee it is also crucial factor for proper posture movement knee. Quadriceps routinely regularly used an assessment during diagnosis many knee-related problems. show...

Objectives: The aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how Total Knee Replacement (TKR) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. Methods: Two-dimensional kinematic gait pattern of 10 participants were collected before and after the TKR surgery,...

One component of conventional total knee arthroplasty is removal of the anterior cruciate ligament, and the knee after total knee arthroplasty has been said to be a knee with anterior cruciate ligament dysfunction. Bicruciate stabilized total knee arthroplasty is believed to reproduce anterior cruciate ligament function in the implant and provide anterior stability. Conventional total knee arth...

A linear piston hydraulic angular-velocity-based control knee joint was designed for people with knee-extensor weakness to engage knee-flexion resistance when knee-flexion angular velocity reaches a preset threshold, such as during a stumble, but to otherwise allow free knee motion. During mechanical testing at the lowest angular-velocity threshold, the device engaged within 2 degrees knee flex...
