Background
Labral tears are common in hip arthroscopy patients and contribute to joint instability and pain. Labral preservation techniques are critical, and augmentation with tendon allograft may be an option for partial labral damage not requiring full reconstruction.
Methods
This technical description details an arthroscopic labral augmentation technique utilizing a tibialis anterior tendon allograft with a knotless pull-through method, aiming to restore labral anatomy and function.
Key Findings
- Labral augmentation provides a less invasive alternative to full reconstruction in selected cases.
- The knotless pull-through technique facilitates graft passage and fixation while preserving native labral tissue.
Conclusions
Labral augmentation with tibialis anterior tendon allograft using the knotless pull-through method is a viable technique to restore labral function in specific tears, potentially reducing surgical morbidity compared to full reconstruction.
What Does This Mean for Providers?
Providers should consider labral augmentation as an intermediate option for labral pathology where preservation is possible but augmentation is required. The knotless pull-through technique can simplify graft management and fixation, potentially improving surgical efficiency and outcomes.
