There are many different materials used for ligament reconstruction. Currently, autograft, allograft, and artificial ligaments are used in the reconstruction. The objective of this study was to explore the clinical result of cruciate ligament reconstruction under arthroscopy.


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. We examined the anterior and posterior stability of the knee with KT-1000.


According to the Lysholm knee function score scale, the average preoperative score of (44.6+/-1.4) increased to a postoperative score of (82.8+/-2.5) in the ACL group and from (46.6+/-2.3) to (80.8+/-2.0) in the PCL group. In the ACL combined with PCL injury group, the preoperative score increased from (45.2+/-1.2) to (85.5+/-2.3). According to IKDC score standards, in ACL group we evaluated 19 cases as C and 24 cases as D, preoperatively, and postoperatively 27 cases as A, 14 cases as B and two cases as C. In the preoperative PCL group, we had 11 cases defined as C and nine cases as D that resolved to 12 cases as A, seven as B and one case of C in postoperative evaluation. In the ACL combined with PCL injury group we defined four cases as C and 14 as D during preoperative scoring. These patients had postoperative grades of six cases as A, 10 as B, and two cases as C. All of the results have statistical significance.


ACL, PCL, or combined ACL and PCL reconstruction using the LARS ligament under arthroscopy is a minimally invasive, safe and effective method to treat cruciate ligament injuries of the knee. Clinical results are satisfactory in the short term.
