Summary

Ligament instability frequently necessitates revision total knee arthroplasty (TKA). Proper component alignment and balanced ligaments are crucial for successful TKA revision outcomes and long-term joint function.

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...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Knee Biomechanics

Background:

  • Ligament instability is a significant complication following total knee arthroplasty (TKA).
  • Identifying the specific cause of instability is critical for successful revision procedures.
  • Revision TKA aims to restore joint stability, function, and longevity.

Purpose of the Study:

  • To analyze the various reasons for ligament instability in revision total knee arthroplasty (TKA).
  • To correlate instability types with component positioning and other intraoperative findings.
  • To provide insights for improving surgical techniques and patient outcomes in revision TKA.

Main Methods:

  • Retrospective analysis of 135 revision TKA cases performed by a single surgeon.

  • Preoperative clinical and radiographic assessment, including component positioning.
  • Intraoperative evaluation of ligament stability (extension, 30°, 90° flexion), wear, patellar mechanics, and component alignment.

    • Main Results:

    • Ligament instability was the primary reason for revision in 32.6% and a secondary reason in 21.6% of cases.
    • Combined instability in extension and flexion was the most frequent type (31.8%), followed by isolated flexion instability (31.8%).
    • A strong correlation was observed between instability and component malpositioning, particularly femoral rotation and tibial component placement.

    Conclusions:

    • Ligament instability is a common indication for revision TKA, presenting in various isolated and combined forms.
    • Accurate anatomical component positioning and balanced soft tissues are essential for stable TKA revisions.
    • Addressing ligamentous balance and precise component alignment is key to achieving favorable long-term clinical results and joint longevity.
