Percutaneous lateral retinacular release offers short-term pain relief and dislocation prevention. However, long-term follow-up reveals increased patellar slipping in patients with recurrent subluxation, suggesting limited suitability for those with chondromalacia.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanical Research

Background:

  • Recurrent patellar instability is a common orthopedic concern.
  • Percutaneous lateral retinacular release (PLRR) is a surgical option for patellar instability.
  • Long-term outcomes of PLRR require further investigation.

Purpose of the Study:

  • To evaluate the long-term efficacy and safety of percutaneous lateral retinacular release.
  • To assess the durability of pain reduction and dislocation prevention after PLRR.
  • To identify factors influencing long-term outcomes and potential complications.

Main Methods:

  • Retrospective review of 34 patients who underwent PLRR.
  • Second follow-up assessment at an average of 48 months post-surgery.

Related Experiment Videos

  • Analysis of patient-reported outcomes, including pain, subluxation, and slipping.

    • Main Results:

    • Short-term satisfactory results for pain and dislocation were maintained.
    • Increased incidence of patellar slipping observed with longer follow-up.
    • Patients with chondromalacia and degenerative joint disease showed poorer long-term outcomes.
    • Only 3% of patients experienced long-term complications.

    Conclusions:

    • PLRR provides short-term benefits for patellar instability.
    • Long-term follow-up indicates a potential for increased patellar slipping.
    • Chondromalacia and degenerative joint disease may contraindicate long-term PLRR success.
