Microfracture + PRP vs Microfracture Alone for OLT: Meta-Analysis
Multiple authors · Foot and Ankle Surgery (2024)
DOI: 10.1016/j.fas.2023.09.003This focused meta-analysis compared arthroscopic microfracture surgery with and without PRP augmentation for osteochondral lesions of the talus. Five RCTs with 198 patients were pooled. The combination of microfracture and PRP produced significantly better pain (VAS) and function (AOFAS) scores compared to microfracture alone.
Clinical Relevance
For foot and ankle surgeons performing microfracture for talar osteochondral lesions, adding PRP provides statistically significant improvement. This may become standard of care for talar microfracture procedures.
Key Takeaways
- 5 RCTs, 198 patients (focused analysis)
- Microfracture + PRP significantly superior for VAS (p<0.001) and AOFAS
- PRP enhances chondrogenic potential of bone marrow stimulation
- Good short-term results; longer follow-up needed
- Supports PRP as standard augmentation for talar microfracture
- More long-term, high-quality studies warranted
Key Findings
5 RCTs, 198 patients. Microfracture + PRP significantly reduced VAS pain (p<0.001) and improved AOFAS function vs microfracture alone. Good short-term results. PRP enhances the biological response to marrow stimulation surgery.
