A novel needle puncturing technique safely addresses medial collateral ligament (MCL) tightness in varus knee arthroplasty. This minimally invasive approach offers progressive correction, enhancing outcomes in total knee replacements.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Traditional
  • pie crusting
  • techniques for knee tightness are unsuitable for varus knees due to medial collateral ligament (MCL) injury risks.
  • Medial soft tissue balancing is crucial for successful varus knee arthroplasty.

Purpose of the Study:

  • To introduce and evaluate a minimally invasive needle puncturing technique for medial soft tissue balancing in varus knee arthroplasty.
  • To assess the safety and efficacy of progressive MCL stretching via needle punctures.

Main Methods:

  • A technique involving multiple 19-gauge needle punctures to progressively stretch the MCL was employed.
  • The procedure was performed intraoperatively in 61 varus knees and percutaneously in 4 cases of postoperative MCL tightness.

  • Success was defined by achieving specific mediolateral joint line openings in extension and flexion.

    • Main Results:

    • The needle puncturing technique successfully achieved progressive correction of MCL tightness in 95% (62/65) of cases.
    • The procedure resulted in the desired joint line opening criteria in the majority of patients.
    • Three cases experienced overrelease, necessitating adjustments with lateral structure release and thicker inserts.

    Conclusions:

    • Needle puncturing is an effective and safe alternative for correcting MCL tightness during minimally invasive total knee arthroplasty.
    • This technique allows for progressive and controlled medial soft tissue balancing with minimal dissection.
    • It offers a valuable option for managing varus knee deformities and postoperative medial tightness.
