Background
Improper anchor placement during hip arthroscopy for labral repair can penetrate articular cartilage, causing anchor arthropathy, pain, and mechanical symptoms.
Methods
The study outlines a revision arthroscopic technique for removal of problematic anchors and concomitant cartilage repair.
Key Findings
- Cartilage penetration by anchors is a significant source of persistent postoperative pain and dysfunction.
- Arthroscopic removal of protruding anchors, combined with cartilage restoration, leads to symptomatic and functional improvement.
Conclusions
Revision hip arthroscopy addressing anchor arthropathy is effective in managing pain and improving outcomes in patients with cartilage-penetrating anchors.
What Does This Mean for Providers
- Careful anchor placement during labral repair is critical to avoid cartilage damage.
- Consider anchor arthropathy in differential diagnosis for persistent pain or mechanical symptoms after hip arthroscopy.
- Arthroscopic revision with anchor removal and cartilage treatment should be considered in symptomatic patients to optimize outcomes.
