Summary
Advancements in arthroscopic meniscal repair techniques, including inside-out and all-inside methods, offer improved outcomes. Biological adjuncts like platelet-rich plasma show promise for enhancing healing rates in meniscal tears.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Biomedical engineering
Background:
- Meniscal tears were once considered untreatable, limiting treatment options.
- Arthroscopic meniscal repair techniques have evolved significantly.
- Inside-out repair is the gold standard, offering precise fixation but requiring specific surgical expertise and incisions.
Purpose of the Study:
- To review technical advancements in meniscal repair.
- To compare inside-out and all-inside arthroscopic meniscal repair techniques.
- To explore the role of biological adjuncts in improving meniscal healing.
Main Methods:
- Review of current arthroscopic meniscal repair techniques, focusing on inside-out and all-inside devices.
- Discussion of biological augmentation strategies, including abrasion, marrow venting, fibrin clots, platelet-rich plasma, and bone marrow aspirate.
- Comparison of repair techniques regarding fixation, surgical requirements, and patient outcomes.
Main Results:
- Inside-out repair offers precise, multi-point fixation but requires specific incisions and experienced surgeons.
- Modern all-inside devices facilitate easier suture placement without additional incisions or specialized personnel.
- Meniscal repair, regardless of technique, improves long-term function compared to meniscectomy.
- Biological adjuncts like marrow venting and fibrin clots show promise in enhancing healing rates.
Conclusions:
- Technical innovations have expanded the treatability of meniscal tears.
- Both inside-out and all-inside techniques have distinct advantages and indications.
- Biological adjuncts represent a promising frontier for improving meniscal repair outcomes, though further research is needed for definitive utility assessment.
