Summary
This study found that Ligament Advancement Reinforcement System (LARS) artificial ligaments offer a viable treatment for knee dislocations. Patients showed satisfactory outcomes, with better results in less severe injuries.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Biomaterials in orthopedics
Background:
- Knee dislocations are severe injuries requiring effective treatment.
- Artificial ligaments offer an alternative to autografts for knee reconstruction.
Purpose of the Study:
- To evaluate the efficacy of Ligament Advancement Reinforcement System (LARS) artificial ligaments for acute knee dislocations.
- To compare outcomes based on injury severity and energy levels.
Main Methods:
- Retrospective study of 71 patients with knee dislocations treated with LARS ligaments.
- Follow-up duration ranged from 2 to 8 years.
- Outcome measures included Lysholm score, IKDC 2000, Tegner score, range of motion, and stability testing.
Main Results:
- Satisfactory subjective and objective outcomes were observed.
- Patients with knee dislocation (KD) II/III injuries showed better Lysholm scores than KD IV.
- Results were comparable to existing literature on knee dislocations.
Conclusions:
- Acute combined repair and reconstruction using LARS ligaments is a valid treatment option for knee dislocations.
- Mean follow-up of 54 months supports the long-term viability of this approach.
- Injury severity influences patient outcomes, with less severe cases faring better.
