Summary
A novel reinforced electrospun construct for deep flexor tendon repair demonstrated comparable biomechanical strength to traditional sutures. This combined mechanical and drug-release approach shows promise for effective tendon healing with reduced adhesions.
Area of Science:
- Biomaterials Science
- Orthopedic Surgery
- Regenerative Medicine
Background:
- Deep flexor tendon injuries require robust repair strategies.
- Current methods like the modified Kessler suture have limitations.
- Combining mechanical support with drug delivery may enhance healing and reduce complications.
Purpose of the Study:
- To evaluate a reinforced tubular, medicated electrospun construct for deep flexor tendon repair in a rabbit model.
- To compare its biomechanical and histological outcomes against its components and a modified Kessler suture.
Main Methods:
- Development of a reinforced tubular, medicated electrospun construct.
- Evaluation in a rabbit model involving 40 New Zealand rabbits.
- Comparison of four repair techniques: reinforced construct, non-reinforced construct, tubular braid, and modified Kessler suture.
- Biomechanical tensile testing, macroscopic, and histological analysis at 3 and 8 weeks post-surgery.
Main Results:
- Experimental techniques showed similar biomechanical strength to the modified Kessler suture (19.85 N at 3 weeks, 18.15 N at 8 weeks).
- Significantly different macroscopic adhesion patterns were observed based on the repair technique.
- Histological assessment indicated good to excellent repair quality across all techniques.
Conclusions:
- The reinforced tubular, medicated electrospun construct is biomechanically comparable to traditional tendon repair methods.
- This approach successfully integrates mechanical support with drug delivery for improved tendon repair.
- The findings support the combination of mechanical and biological strategies for flexor tendon repair.
