Summary
The two-strand side-locking loop technique with cross-stitch epitendinous repair allows for safe, early active mobilization after tendon surgery. This method enhances repair strength and reduces adhesion formation without needing specialized rehabilitation staff.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Regenerative medicine
Background:
- Early mobilization post-tendon repair is crucial for reducing adhesions and improving strength.
- Investigating the tolerance of the two-strand side-locking loop technique to immediate aggressive active mobilization.
Purpose of the Study:
- To evaluate the efficacy of the two-strand side-locking loop technique with cross-stitch epitendinous repair for immediate active mobilization.
- To compare this technique against the 8-strand repair method.
Main Methods:
- Twelve porcine flexor digitorum profundus tendons were repaired using either the two-strand side-locking loop technique with cross-stitch (Group A) or an 8-strand simple running suture (Group B).
- Tendon gap formation and residual tensile strength were measured after cyclic loading (3-50 N for 10,000 cycles).
Main Results:
- Group A exhibited significantly smaller gaps (0.5-1.2 mm) compared to Group B (3.5-5.2 mm) after cyclic loading.
- Group A demonstrated superior residual tensile strength (207.1 N) compared to Group B (84.2 N).
Conclusions:
- The combination of the two-strand side-locking loop technique and cross-stitch epitendinous repair is optimal for safe and early active mobilization.
- This suture method facilitates early mobilization without requiring specialized rehabilitation support.
