Knee Prosthesis in the Computer Era [PDF]

open access: yesOrthopaedic Surgery, 2021
Over the past two decades, computer assistance has revolutionalized surgery and has enabled enormous advancements in knee prosthesis surgery. Total knee arthroplasty (TKA) is a hot topic of orthopaedic research.

Can microprocessor knees reduce the disparity in trips and falls risks between above and below knee prosthesis users? [PDF]

open access: yesPLoS ONE, 2022
While all lower limb prosthesis walkers have a high risk of tripping and/or falling, above knee prosthesis users are reported to fall more frequently. Recognising this, engineers designed microprocessor knees (MPK) to help mitigate these risks, but to ...

Alignment of the above-knee prosthesis/1 [PDF]

open access: bronzeProsthetics & Orthotics International, 1979
1. A long prosthesis forces drop of the pelvis on the normal side, can cause crotch pressure and distal femoral pressure leading to discomfort, can reduce voluntary control, may force the amputee to walk with an abducted stump hip for stance phase and to swing the leg outward for toe clearance in swing phase or to compensate by rising up on the sound ...

Kinematic Analysis of a Posterior-stabilized Knee Prosthesis

open access: yesChinese Medical Journal, 2015
Background: The goal of total knee arthroplasty (TKA) is to restore knee kinematics. Knee prosthesis design plays a very important role in successful restoration.

Effects of extended powered knee prosthesis stance time via visual feedback on gait symmetry of individuals with unilateral amputation: a preliminary study

open access: yesJournal of NeuroEngineering and Rehabilitation, 2019
Background Establishing gait symmetry is a major aim of amputee rehabilitation and may be more attainable with powered prostheses. Though, based on previous work, we postulate that users transfer a previously-learned motor pattern across devices ...

Radiographic Assessment of Aseptic Loosening of Tumor‐Type Knee Prosthesis in Distal Femur [PDF]

open access: yesOrthopaedic Surgery, 2022
Objective To measure the full‐length anteroposterior and lateral radiographs of lower limbs after the resection of a tumor in the distal femur and tumor‐type knee prosthesis replacement and to analyze the factors leading to aseptic loosening of the ...

Atraumatic patellar prosthesis dislocation with patellar tendon injury following a total knee arthroplasty: a case report [PDF]

open access: goldJournal of Medical Case Reports, 2010
Introduction Total knee arthroplasty is a well-established procedure with gratifying results. There is no consensus in the literature whether to routinely resurface the patella while performing total knee arthroplasty or not.

Development of a Passive Knee Motion Simulator to Evaluate Deep Knee Flexion of Total Knee Prosthesis

open access: bronzeJournal of Biomechanical Science and Engineering, 2009
To evaluate motions and joint reaction forces of the total knee prosthesis during deep knee flexion such as kneeling and sitting straight, a simulator that reproduces the passive motion of the knee has been developed. The main feature of the simulator is
