Summary
Gluteus medius/minimus tears can be treated with open repair using allograft augmentation. This surgical option enhances repair strength for chronic tears, improving hip function and reducing pain.
Area of Science:
- Orthopedic Surgery
- Regenerative Medicine
- Biomaterials Science
Background:
- Gluteus medius/minimus tears are prevalent, particularly in older women, stemming from acute trauma or chronic degeneration.
- Treatment selection hinges on tear severity, with allograft augmentation emerging as a viable option for poor tendon quality or retracted tears.
Purpose of the Study:
- To describe the surgical technique and outcomes of open gluteus medius/minimus reconstruction utilizing biphasic enthesis allograft and acellular dermal allograft.
Main Methods:
- The procedure involves open exposure of the gluteal tendons, preparation of the trochanteric footprint, and inlay placement of a biphasic enthesis allograft.
- An onlay human dermal allograft is then affixed to the torn tendon, with sutures secured in a double-row configuration to enhance repair integrity.
Main Results:
- This study represents the first documented use of biphasic enthesis allograft for gluteal reconstruction.
- Open gluteal reconstructions have demonstrated positive impacts on patient-reported outcomes, pain reduction, and improved hip functionality.
Conclusions:
- Open reconstruction with inlay biphasic enthesis allograft and onlay acellular dermal allograft offers immediate structural support for gluteal tears.
- Allograft augmentation is particularly beneficial for retracted tears and cases with significant fatty infiltration, mirroring successful applications in rotator cuff repair.
