2019年11月2日 · There has been continuing debate about the superiority of cruciate-retaining (CR) total knee arthroplasty (TKA) versus posterior-stabilized (PS) TKA for obtaining knee joint stability with functional improvement.

2022年12月15日 · Posterior-stabilized (PS)-total knee arthroplasty (TKA) arose as an alternative to cruciate-retaining (CR)-TKA in the 1970s. Since then, it has become a popularly utilized TKA design with outcomes comparable to CR-TKA.

2025年2月20日 · recent literature suggests CR-TKA designs demonstrate a greater increase in patellofemoral contact pressures when compared to other TKA designs Posterior Stabilized (PS) Design Design

2017年2月2日 · Patellar Clunk syndrome is associated with the PS-TKA because suprapatellar scar tissue can get caught within the cam as the knee goes into extension around 30-45° (the patella starts traveling proximally and the prominent scar tissue catches the lip).

2014年7月19日 · 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.

2022年1月1日 · The CS TKA relies on the posterior capsule, collateral ligaments, and articular conformity without a cam or post to achieve stability. Using prospectively collected data we compared clinical outcomes of CS TKA to posterior-stabilized (PS) TKA utilizing a …

2021年5月16日 · PS knees have consistently shown greater degrees of flexion attributed to unique implant design and surgical techniques intended to prevent impingement of the posterior tibial articulating surface and the posterior femoral metaphysis.

Although being debated for many years, the superiority of posterior cruciate-retaining (CR) total knee arthroplasty (TKA) and posterior-stabilized (PS) TKA remains controversial. We compare the knee scores, post-operative knee range of motion (ROM), ...

2024年12月3日 · PS-TKA uses a post–cam mechanism that compensates for posterior cruciate ligament (PCL) function to improve the range of motion (ROM) and anteroposterior instability of total condylar TKA, an anterior cruciate ligament (ACL)/PCL resection-type TKA.

2018年12月6日 · The primary goal when balancing a PS TKA prosthesis is to create functional range of motion with stability of both flexion and extension gaps. The role of PCL release in achieving this goal is significant.
