Purpose
To describe a technique for arthroscopic reconstruction of the ligamentum teres (LT) in patients with traumatic full-thickness LT tears causing hip instability.
Methods
Technical report outlining arthroscopic LT reconstruction using semitendinosus autograft or allograft with the patient supine.
Key Findings
- LT plays a role in hip stability; tears can cause pain and mechanical instability.
- Reconstruction is indicated in patients with documented traumatic LT tears and overt instability.
- The described arthroscopic approach provides minimally invasive restoration of LT function.
Conclusion
Arthroscopic LT reconstruction is a viable option for managing hip instability related to LT tears and addresses a previously controversial indication.
What Does This Mean for Providers?
- Providers should consider LT reconstruction in patients with traumatic hip instability refractory to conservative management.
- Mastery of arthroscopic graft fixation techniques and hip anatomy is necessary.
- This procedure expands treatment options for a difficult-to-manage cause of hip instability and may improve patient outcomes.
