Area of Science:

• Orthopedic Surgery
• Biomaterials Science
• Regenerative Medicine

Background:

• Rotator cuff tears often present with associated bone defects, such as greater tuberosity cysts.
• Restoring bone stock and achieving a stable rotator cuff repair are crucial for functional recovery.
• Current techniques may require multiple stages, increasing patient morbidity.

Purpose of the Study:

• To describe a novel one-stage surgical technique for rotator cuff repair in the presence of bone defects.
• To evaluate the feasibility of augmenting cystic lesions with an injectable bone void filler.
• To combine bone reconstruction with double-row rotator cuff repair.

Main Methods:

• A one-stage procedure combining rotator cuff reconstruction with augmentation of bone defects using an injectable, absorbable, biocompatible, fiber-reinforced bone void filler.
• The technique was applied to patients with rotator cuff tears and associated greater tuberosity cysts.
• A double-row rotator cuff reconstruction was performed concurrently with bone void augmentation.

Main Results:

• The study reports on six patients treated with this one-stage technique.
• The procedure addresses both the rotator cuff tear and the bone void in a single intervention.
• Long-term outcome data are not yet available.

Conclusions:

• The presented one-stage technique offers a potential solution for combined rotator cuff tears and bone defects.
• This approach may simplify treatment and improve outcomes for specific patient populations.
• Further investigation and long-term follow-up are necessary to validate the efficacy and durability of this method.
