Knee Joint01:23

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...

Summary

Computed tomography (CT) measurements for rotational limb alignment after total knee arthroplasty (TKA) are reproducible. TKA component rotation significantly impacts overall limb alignment, especially with fixed-bearing implants.

Area of Science:

  • Orthopedic surgery
  • Biomechanical analysis
  • Medical imaging

Background:

  • Accurate rotational alignment is crucial for optimal outcomes in total knee arthroplasty (TKA).
  • Preoperative and postoperative assessment of limb alignment using computed tomography (CT) is essential for surgical planning and evaluation.

Purpose of the Study:

  • To evaluate rotational alignment changes following TKA.
  • To determine the reproducibility of pre- and postoperative CT measurements for rotational limb alignment.

Main Methods:

  • Analysis of 196 cruciate-retaining, fixed-bearing Columbus TKA procedures.
  • CT scans used to measure neck-malleolar angle (NMA), femoral posterior condylar angle (fPCA), tibial posterior condylar axis (tPCA), and tibial torsion angle (TTA).
  • Independent assessment by three raters, with re-evaluation for intraobserver agreement.

Main Results:

  • Interindividual variability observed in all angle measurements.
  • Mean fPCA showed a shift towards internal rotation postoperatively.
  • Significant relative internal rotation of NMA and tibial torsion observed post-TKA.
  • Strong intra- and interobserver agreement for most angles, except fPCA, which had clinically acceptable measurement differences.

Conclusions:

  • CT measurements for rotational limb alignment in TKA demonstrate clinically acceptable reproducibility.
  • Femoral and tibial component rotation after TKA influences overall limb rotational alignment, particularly with fixed-bearing designs.
