Summary
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.
- 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.
