Knee Joint

3.5K
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
  • Biomechanical Engineering

Background:

  • Severe varus deformity in total knee arthroplasty (TKA) often necessitates extensive medial soft tissue release.
  • Extensive release can lead to joint instability, complicating TKA outcomes.

Purpose of the Study:

  • To present and evaluate a novel soft tissue balancing technique for TKA in severe varus deformity.
  • To minimize medial release while ensuring joint stability during TKA.

Main Methods:

  • A new technique involving superficial medial collateral ligament (SMCL) manipulation for flexion gap balancing and gradual extension with trial components for extension gap balancing was used in 50 knees (Group 1).
  • A propensity score-matched control group (50 knees) with mild varus deformity (Group 2) was selected for comparison.
  • Mediolateral laxity was assessed using stress radiographs at 1-year post-operation. Clinical outcomes were evaluated using the Knee Society Score and Western Ontario and McMaster Universities Osteoarthritis Index.

Main Results:

  • No significant differences in medial laxity (2.3° ± 1.4° vs. 2.7° ± 1.3°) or lateral laxity (3.6° ± 1.7° vs. 3.2° ± 2.0°) were observed between the groups at 1-year follow-up.
  • Postoperative clinical scores and knee alignment showed no significant variations between the severe varus group and the mild varus control group.

Conclusions:

  • The described technique for extension gap balancing using trial components is safe and effective.
  • This method successfully balances the knee joint in severe varus deformity during TKA, avoiding excessive medial release and potential instability.
