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...

Area of Science:

Orthopedic surgery
Biomedical engineering
Arthroplasty research

Context:

Partial knee replacement (PKR) is effective for unicompartmental knee arthroplasty.
Total knee arthroplasty (TKA) remains preferred globally due to historical reasons.
Advancements in implants and surgical techniques for PKR continue.

Purpose:

Evaluate PKR advantages and disadvantages with long-term data.
Analyze the evolution of indication criteria for PKR.
Explore new patient selection aspects and emerging technologies for PKR.

Summary:

Long-term results show excellent prosthetic survival for current partial knee replacements, matching TKA outcomes.
Expanded indication criteria for PKR now encompass severe deformities, ligament insufficiency, and patellofemoral issues.
Emerging technologies offer potential improvements in precision and error reduction for PKR.

Impact:

PKR demonstrates comparable long-term success to TKA, challenging historical preferences.
Broader patient eligibility for PKR is supported by updated clinical insights.
Success of PKR should be assessed comprehensively beyond revision rates.
