Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Revision total knee arthroplasty (TKA) using mobile bearing rotating platform (RP) implants shows promising functional outcomes and improved wear performance. This design may reduce stress on the implant interface, potentially enhancing long-term TKA success.

Area of Science:

Orthopedic surgery
Biomedical engineering
Materials science

Background:

Revision total knee arthroplasty (TKA) is performed for failed primary knee replacements.
Long-term outcomes of revision TKA are generally inferior to primary TKA.
Mobile bearing (MB) designs may offer improved functional performance in revision settings.

Purpose of the Study:

To evaluate the clinical and biomechanical performance of MB rotating platform (RP) revision TKAs.
To compare the wear performance of MB RP revision knees with fixed bearing (FB) revision knees.

Main Methods:

Clinical outcomes of 44 MB RP revision TKAs were assessed using the Knee Injury and Osteoarthritis Outcome Score (KOOS).
Wear testing was conducted to compare MB RP revision knees with FB revision knees.

Treatment of Ankle Osteoarthritis with Total Ankle Replacement Through a Lateral Transfibular Approach

Published on: January 24, 2018

Main Results:

Patients reported a mean KOOS Activities of Daily Living score of 77 two years postoperatively.
Wear testing demonstrated superior wear performance for MB RP revision knees compared to FB revision knees.

Conclusions:

The MB RP construct is a suitable option for revision TKA.
This design allows for improved implant fixation and rotation.
It may reduce shear stress at the bone-cement-implant interface, a common failure mode.
