This systematic review evaluated outcomes of fixation techniques for unstable knee osteochondritis dissecans lesions, analyzing 39 studies with 1070 patients. Arthroscopic fixation using bioabsorbable implants demonstrated high functional scores and lower complication rates compared to open fixation and metal implants. Notably, bioabsorbable implants were linked to fewer reoperations.
Key findings
- Arthroscopic fixation yielded Lysholm scores ranging from 85.3 to 98.9.
- Open fixation showed Lysholm scores from 39 to 99 and reoperation rates up to 22% with metal implants.
- Combined approaches produced postoperative Lysholm scores from 82.1 to 97.
- Skeletally immature patients had better healing and lower reoperation rates.
Why it matters
Understanding the comparative effectiveness of fixation techniques for knee osteochondritis dissecans is crucial for optimizing patient outcomes. This review highlights the advantages of arthroscopic bioabsorbable fixation, which may influence surgical decision-making and improve recovery trajectories.
