    Summary

    Endoscopic lateral release surgery effectively treats lateral subluxation syndrome of the patellofemoral joint. This minimally invasive technique offers favorable outcomes, with nearly half of patients experiencing excellent results and symptom resolution.

    Area of Science:

    • Orthopedic Surgery
    • Sports Medicine
    • Biomechanics

    Background:

    • Lateral subluxation syndrome of the patellofemoral joint is a common cause of knee pain.
    • Patellofemoral malalignment can lead to significant functional limitations and decreased quality of life.
    • Various surgical techniques exist for managing this condition, each with its own efficacy and complication profile.

    Purpose of the Study:

    • To evaluate the effectiveness of endoscopic lateral release in treating lateral subluxation syndrome of the patellofemoral joint.
    • To compare the outcomes of endoscopic lateral release with other treatment modalities for patellofemoral malalignment.
    • To assess subjective patient-reported outcomes and return to activity levels after endoscopic lateral release.

    Main Methods:

    Related Experiment Videos

  • A prospective study analyzing 39 knees with lateral subluxation syndrome.
  • Patients underwent endoscopic lateral release surgery.
  • Follow-up examinations were conducted at 18 months, utilizing subjective criteria for outcome assessment.

    • Main Results:

    • Excellent subjective ratings (complete symptom absence, return to full activity) were achieved in 48.7% of knees (19/39).
    • A further 33.3% of knees (13/39) showed improvement, with a mean subjective rating of 6.8/10.
    • 18.0% of knees (7/39) had poor outcomes with no improvement in symptoms or activity levels.

    Conclusions:

    • Endoscopic lateral release is a favorable treatment option for lateral subluxation syndrome of the patellofemoral joint.
    • The procedure demonstrates good to excellent subjective outcomes in a majority of patients.
    • Further research may explore objective measures and long-term results to complement subjective findings.
