Abstract

Background

The aims of this study were to analyze the long-term clinical effects of arthroscopic reconstruction of posterior cruciate ligament (PCL) using Ligament Advanced Reinforcement System (LARS) artificial ligament. It is hypothesized that LARS artificial ligament is a safe and effective choice for PCL reconstruction, providing good knee stability.

Methods

Sixty-one patients who underwent PCL reconstruction using LARS artificial ligament (Y-type) were enrolled in this retrospective study. Average age at time of surgery was 34 yrs old (range, 23-57 y). Average time from injury to surgery was 15 d (range, 5–45 d). Average follow-up period was 5 years (range, 44-72 months). Follow-up examinations included the Lysholm Knee Score and the International Knee Documentation Committee (IKDC) score.

Results

The average Lysholm knee score was 64.9 ± 8.8 preoperatively (range, 47-75) versus 92.1 ± 3.3 four years after operation (range, 79–100). Fifty-four of 41 patients (88%) showed good or excellent results at final assessment. The final IKDC score at 4yrs postoperatively rated as normal in 56 patients (92%), nearly normal in 4 patients (7%), abnormal in 1 patients (2%).

Conclusion

The results shows that Y-type LARS artificial ligament appears to be an effective device for PCL reconstruction, long-term follow-up proved the durable stability of the knee and the tolerance of the knee to the LARS artificial ligament.
