Kinematic analysis of posterior-stabilized total knee arthroplasty during standing up from and sitting down on a chair
BACKGROUND Total knee arthroplasty is effective to regain quality of life. Standing up from and sitting down on a chair and stair stepping motion are important in daily living. We previously reported in vivo kinematics of this implant during a stepping exercise. The purpose of this analysis was to assess in vivo knee motion during standing up from and sitting down on a chair and determine the m...
متن کاملPosterior Stabilized Total Knee Arthroplasty
The posterior cruciate ligament (PCL) in total knee arthroplasty (TKA) functions to prevent posterior translation of the tibia and aids in femoral roll-back1. Roll-back allows for increased quadriceps lever arm and more efficient use of extensor musculature, permitting more normal stair climbing. Because of this, PCL retaining knees have the advantage of maintenance of ligamentous proprioceptio...
متن کاملA kinematic comparison between elderly and young subjects standing up from and sitting down in a chair.
BACKGROUND AND AIMS The transfer from sitting to standing and back to sitting as the two phases of the same task has never been studied in elderly people. The purposes of this study were to analyse and compare kinematic features of the whole task (standing up and sitting down) and to determine whether there are age-related differences upon movement kinematics in healthy elderly persons during t...
متن کاملPrimary posterior stabilized total knee arthroplasty: analysis of different instrumentation
BACKGROUND Intercondylar femoral bone removal during posterior stabilized (PS) total knee arthroplasty (TKA) makes many cruciate substituting implant designs less appealing than cruciate retaining implants. Bone stock conservation is considered fundamental in the prevision of future revision surgeries. The purpose of this study was to compare the quantity of intercondylar bone removable during ...
متن کاملPosterior cruciate ligament removal contributes to abnormal knee motion during posterior stabilized total knee arthroplasty.
Abnormal anterior translation of the femur on the tibia has been observed in mid flexion (20-60 degrees ) following posterior stabilized total knee arthroplasty. The underlying biomechanical causes of this abnormal motion remain unknown. The purpose of this study was to isolate the effects of posterior cruciate ligament removal on knee motion after total knee arthroplasty. We posed two question...
