Summary
The LARS artificial ligament provides a safe and effective solution for knee cruciate ligament reconstruction, showing significant improvements in function and stability. This minimally invasive arthroscopic surgery yields satisfactory short-term clinical results for anterior and posterior cruciate ligament injuries.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Ligament reconstruction commonly utilizes autografts, allografts, or artificial ligaments.
- Arthroscopic techniques are increasingly explored for cruciate ligament repair.
Purpose of the Study:
- To evaluate the clinical outcomes of knee cruciate ligament reconstruction using the LARS artificial ligament.
- To assess the efficacy of arthroscopic LARS ligament reconstruction for anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and combined injuries.
Main Methods:
- Eighty-one patients underwent arthroscopic reconstruction with the LARS ligament (43 ACL, 20 PCL, 18 combined).
- Functional outcomes were assessed using the Lysholm knee score and International Knee Documentation Committee (IKDC) scales.
- Knee stability was evaluated using the KT-1000 arthrometer over a 10-49 month follow-up period.
Main Results:
- Significant improvements in Lysholm scores were observed across all groups post-surgery.
- IKDC evaluations showed a notable shift towards 'A' and 'B' grades postoperatively compared to preoperative 'C' and 'D' grades.
- KT-1000 measurements indicated improved anterior and posterior knee stability, with statistically significant results.
Conclusions:
- Arthroscopic reconstruction with the LARS ligament is a minimally invasive, safe, and effective treatment for knee cruciate ligament injuries.
- The study demonstrates satisfactory short-term clinical results for ACL, PCL, and combined cruciate ligament reconstructions.
