Retrospective study – Gliatis Pleases – World Journal of Orthopedics – 2017

Subject : Complex knee injuries treated in acute phase: Long-term results using Ligament Augmentation and Reconstruction System artificial ligament.
Resume : From September 1997 to June 2010, thirty-eight complex knee injuries were treated, where early arthroscopic PCL reconstructions were undergone, using the LARS (Surgical Implants and Devices, Arc-sur-Tille, France) artificial ligament.
Institutional review board statement: The study was reviewed and approved by the Ethical Committee of University Hospital of Patras.

Cruciate ligament reconstruction using LARS artificial ligament under arthroscopy: 81 cases report – Chinese Medical Journal – 2010 

Background: There are many different materials used for ligament reconstruction. Currently, autograft, allograft, and artificial ligaments are used in the reconstruction.
Method: Eighty-one cases were reconstructed with the LARS ligament under arthroscopy, including 43 cases of anterior cruciate ligament (ACL) injury, 20 cases of posterior cruciate ligament (PCL) injury, and 18 cases of ACL combined with PCL injuries of the knee.
The follow up period was 10 to 49 months. The International Knee Documentation Committee (IKDC) and Lysholm knee score scales were used for functional evaluation.

Arthroscopic Posterior Cruciate Ligament Reconstruction Using LARS Artificial Ligament: Journal of Surgical Research – 2010

Purpose: The aims of this study were to analyze the preliminary clinical effects of arthroscopic recon- struction of posterior cruciate ligament (PCL) using Ligament Advanced Reinforcement System (LARS) ar- tificial ligament. It is hypothesized that LARS artificial ligament is a safe and effective choice for PCL recon- struction, providing good knee stability.
Materials and methods: Forty-one patients who un- derwent PCL reconstruction using LARS artificial liga- ment were enrolled in this retrospective study.

Reconstruction of posterior cruciate ligament rupture and posterolateral instability with synthetic ligaments  – Surgical techniques in Orthopaedics and Traumatologie – J.P. Laboureau – 2001)

The principle of internal ligament fixation : If we base the results of posterior cruciate ligament (PCL) reconstruction using autografts or allografts on accurate radiolaximetry, the mechanical efficiency is poor. Objective good mechanical results 12, +, 6, 10, 131 hardly attain 50% in the best of cases. Autogenous transplants require a postoperative period of rest, due to long periods of weaknessess related to collagen transformation and revascularisation. From the start, PCL reconstructions must resist gravity and permanent hamstring action.
