Lateral retinacular release effectively manages anterior knee pain and patellofemoral issues when indicated precisely. Less invasive techniques offer pain relief with reduced risks, guiding modern surgical approaches.
Area of Science:
- Orthopedic Surgery
- Knee Biomechanics
Background:
- Lateral retinacular release (LRR) has been used for extensor mechanism disorders.
- Previous indiscriminate use led to variable functional outcomes.
Purpose of the Study:
- Analyze evolving indications and clinical effectiveness of LRR.
- Compare recent literature (10 years) with classic findings.
Main Methods:
- Systematic literature review.
- Analysis of indications and outcomes in patellofemoral joint pathologies.
Main Results:
- Less extensive LRR aids pain control by decompressing the lateral patellar facet.
- LRR is indicated for lateral patellar hypercompression syndrome without instability.
- Adjuvant role in recurrent patellar instability surgery.
- Promising results for osteoarthritis when combined with debridement.
- Used in total knee replacement for valgus deformity correction.
Conclusions:
- Precise differentiation of patellofemoral pathologies is crucial for LRR indication.
- Further randomized controlled trials with long-term follow-up are needed.
