Summary
This study developed new instruments and techniques for meniscal suture with tendon repair, demonstrating feasibility and effectiveness in improving patient outcomes and reducing pain.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Sports medicine
Background:
- Meniscal injuries are common, particularly in athletes.
- Current meniscal repair techniques have limitations.
- Tendon grafts offer potential for robust meniscal repair.
Purpose of the Study:
- To design and validate novel instruments for meniscal suture using tendon.
- To assess the feasibility and therapeutic efficacy of this new meniscal repair technique.
Main Methods:
- Developed 19 new or improved surgical instruments.
- Treated 45 patients with meniscal injuries using autogeneic or xenogenic tendon sutures.
- Evaluated outcomes using clinical assessments and Lysholm scores.
Main Results:
- All surgeries were successful without neurovascular complications.
- Significant improvement in Lysholm scores (53.0 to 87.8) post-operation (P < 0.01).
- Complete resolution of pain, swelling, and locking symptoms at 6-month follow-up.
Conclusions:
- The novel instruments and technique are feasible for meniscal suture with tendon.
- This method provides an effective short-term solution for meniscal repair.
