Characteristics of bone tunnel changes after anterior cruciate ligament reconstruction using Ligament Advanced Reinforcement System artificial ligament

Background  There are different materials used for anterior cruciate ligament (ACL) reconstruction. It has been reported that both autologous grafts and allografts used in ACL reconstruction can cause bone tunnel enlargement. This study aimed to observe the characteristics of bone tunnel changes and possible causative factors following ACL reconstruction using Ligament Advanced Reinforcement System (LARS) artificial ligament.

Methods  Forty-three patients underwent ACL reconstruction using LARS artificial ligament and were followed up for 3 years. X-ray and CT examinations were performed at 1, 3, 6, 12, 24, and 36 months after surgery, to measure the width of tibial and femoral tunnels. Knee function was evaluated according to the Lysholm scoring system. The anterior and posterior stability of the knee was measured using the KT-1000 arthrometer.

Results  According to the Peyrache grading method, grade 1 femoral bone tunnel enlargement was observed in three cases six months after surgery. No grade 2 or grade 3 bone tunnel enlargement was found. The bone tunnel enlargement in the three cases was close to the articular surface with an average tunnel enlargement of (2.5±0.3) mm. Forty cases were evaluated as grade 0. The average tibial and femoral tunnel enlargements at the last follow-up were (0.8±0.3) and (1.1±0.3) mm, respectively. There was no statistically significant difference in bone tunnel width changes at different time points (P >0.05). X-ray and CT measurements were consistent.

Conclusions  There was no marked bone tunnel enlargement immediately following ACL reconstruction using LARS artificial ligament. Such enlargement may, however, result from varying grafting factors involving the LARS artificial ligament or from different fixation methods.

Cruciate ligament reconstruction using LARS artificial ligament under arthroscopy: 81 cases report

Background 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. Methods 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. Results 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. Conclusions 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.     

COA：Characteristics of Bone Tunnel Changes after Anterior Cruciate Ligament Reconstruction Using LARS Artificial Ligament

[Abstract] Purpose: The purpose of this study was to observe the characteristics of bone tunnel changes and possible causative factors following anterior cruciate ligament (ACL) reconstruction using LARS artificial ligament. Methods: Forty-three (43) patients underwent ACL reconstruction using LARS artificial ligament and were followed up for 3 years. X-ray and CT examinations were performed at 1, 3, 6, 12, 24 and 36 months after surgery, respectively, to measure the width of tibial and femoral tunnels. Knee function was evaluated according to the Lysholm scoring system. The anterior and posterior stability of the knee was measured using the KT-1000arthrometer. Results: According the Peyrache grading method, grade 1 femoral bone tunnel enlargement was observed in three cases six months after surgery. No grade 2 or grade 3 bone tunnel enlargement was found. The bone tunnel enlargement in three cases was close to the articular surface with an average tunnel enlargement of (2.5 ± 0.3) mm. Forty (40) cases were evaluated as grade 0. The average tibial and femoral tunnel enlargements at the last follow-up were 0.8 ± 0.3 mm and 1.1 ± 0.3 mm, respectively. There was no statistically significant difference in bone tunnel width changes at different time points (P>0.05). X-ray and CT measurements were consistent. Conclusions: There was no marked bone tunnel enlargement immediately following ACL reconstruction using LARS artificial ligament. Such enlargement may, however, result from varying grafting factors involving the LARS artificial ligament or from different fixation methods.
