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.
用于韧带重建的材料有很多种。目前，在重建中使用自体移植物、同种异体移植物和人工韧带。本研究的目的是探讨关节镜下十字韧带重建的临床效果。
81 例患者采用 LARS 韧带在关节镜下进行重建，其中前十字韧带（ACL）损伤 43 例，后十字韧带（PCL）损伤 20 例，ACL 合并 PCL 损伤 18 例。随访时间为 10 至 49 个月。采用国际膝关节文献委员会（IKDC）和 Lysholm 膝关节评分量表进行功能评估。我们使用 KT-1000 检查膝关节的前向和后向稳定性。
根据 Lysholm 膝关节功能评分量表，ACL 组术前平均评分为（44.6±1.4）分，术后评分为（82.8±2.5）分；PCL 组术前平均评分为（46.6±2.3）分，术后评分为（80.8±2.0）分。在 ACL 合并 PCL 损伤组中，术前评分从（45.2±1.2）分增加到（85.5±2.3）分。根据 IKDC 评分标准，ACL 组术前 19 例为 C 级，24 例为 D 级，术后 27 例为 A 级，14 例为 B 级，2 例为 C 级。PCL 组术前 11 例为 C 级，9 例为 D 级，术后 12 例为 A 级，7 例为 B 级，1 例为 C 级。在 ACL 合并 PCL 损伤组中，术前 4 例为 C 级，14 例为 D 级，术后 6 例为 A 级，10 例为 B 级，2 例为 C 级。所有结果均具有统计学意义。
关节镜下采用 LARS 韧带重建 ACL、PCL 或 ACL 合并 PCL 损伤是一种微创、安全、有效的治疗膝关节十字韧带损伤的方法。短期临床效果满意。
