This study introduces a novel, incision-free arthroscopic technique for patellar realignment, demonstrating significant improvements in patient outcomes and knee stability. The minimally invasive approach offers comparable or superior results to traditional methods for patellar instability.

Area of Science:

  • Orthopedic Surgery
  • Arthroscopy
  • Knee Biomechanics

Background:

  • Patellar instability is a common condition requiring surgical intervention.
  • Traditional proximal realignment techniques often involve open procedures or arthroscopically assisted methods requiring medial incisions.
  • There is a need for minimally invasive arthroscopic techniques for patellar realignment.

Purpose of the Study:

  • To describe a novel, entirely arthroscopic technique for proximal patellar realignment.
  • To evaluate the 2-year follow-up outcomes of this arthroscopic technique for patellar instability.
  • To assess the feasibility and efficacy of an incision-free arthroscopic approach for patellar realignment.

Main Methods:

  • A retrospective review of 26 patients (29 knees) with patellar instability treated with arthroscopic all-inside medial reefing and lateral release.

Related Experiment Videos

  • Percutaneous suture passage followed by arthroscopic retrieval and knot tying within the joint.
  • Initiation of healing response via medial retinaculum shaving or radiofrequency thermal treatment prior to knot tying.

    • Main Results:

    • 93% of patients reported significant subjective improvement in knee function and pain.
    • Significant improvements were observed in Lysholm scores (41.5 to 79.3) and radiographic parameters (congruence angle, lateral patellofemoral angle, lateral patella displacement).
    • No complications or redislocations occurred, with notable improvements in pain, swelling, and return to sports.

    Conclusions:

    • Arthroscopic patellar realignment using this technique is a viable and effective treatment option.
    • The technique provides results comparable or superior to open or arthroscopically assisted methods.
    • This incision-free arthroscopic approach offers a minimally invasive solution for patellar instability with excellent patient outcomes.
