LARS人工韧带与自体腘绳肌腱重建前交叉韧带早期临床疗效比较 总被引:13,自引:0,他引:13
目的:前瞻性对照研究LARS人工韧带与四股自体腘绳肌腱(ST/G)重建前交叉韧带(ACL)手术的早期临床疗效。方法:自2004年8月至2005年6月,前瞻性选择了42例前交叉韧带损伤病例,根据LARS人工韧带使用指征、医生建议和患者意愿,分别选择自体腘绳肌腱或LARS人工韧带作为移植物。其中LARS韧带重建ACL病例23例,两端以挤压螺钉固定;四股自体腘绳肌腱重建ACL病例19例,股骨端Endobutton悬吊固定,胫骨端Intrafix挤压螺钉和Spiked-washer拴桩双重固定。均在术前及术后3个月、6个月、9个月和15个月进行Lysholm、TegnerI、KDC评分。结果:采用LARS人工韧带的病例,在术后9个月的随访期内,三种膝关节功能评分值均显著高于自体腘绳肌腱ACL重建的病例(P<0.05)。结论:应用LARS人工韧带重建ACL较使用自体腘绳肌腱重建术后膝关节功能恢复更快。 相似文献

This is the first report of an anatomic double-bundle ACL and PCL reconstruction procedure with the autogenous hamstring tendons.
We prepare two pairs of the doubled tendon grafts, to which a polyester tape and an Endobutton-CL are attached using our original
technique at the tibial and femoral ends, respectively. Under arthroscopic and fluoroscopic observations, two tibial tunnels
for PCL reconstruction are created so that they pass through the posteromedial and anterolateral bundle attachments, respectively.
Then, we create two tibial tunnels for anatomic double-bundle ACL reconstruction so that each tunnel axis is aimed at a targeted
point on the femoral condyle. Using the outside-in technique, two femoral tunnels for PCL reconstruction are created so that
the tunnel outlets are located at the center of the anterolateral and posteromedial bundle attachments. Then, two femoral
tunnels for anatomic double-bundle ACL reconstruction are created with the trans-tibial tunnel technique. After the two grafts
have been placed for PCL reconstruction, the two grafts are placed for ACL reconstruction. After all the femoral graft ends
are fixed, the knee joint is reduced to the full extension position, and then, the four tibial tape portions are simultaneously
fixed with the turn-buckle stapling technique. 相似文献

Diagnostic evaluation of posterior cruciate ligament injuries 总被引:3,自引:1,他引:2
Margheritini Fabrizio Mariani Pier Paolo 《Knee surgery, sports traumatology, arthroscopy》2003,11(5):282-288
The posterior cruciate ligament is one of the most controversial issues in sports medicine. There is no consensus in the literature with respect to its incidence, natural history, and treatment indications. Injury evaluation is often underestimated, with the result of misdiagnosed injury or wrong treatment. This contribution reviews the principles of diagnostic evaluation of posterior cruciate ligament injuries. 相似文献

The purpose of this study was to evaluate the clinical results of simultaneous arthroscopically assisted reconstruction of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) using autogenous tendon grafts in chronic knee injuries. Nineteen patients (17 men and 2 women) with chronic multi-ligamentous injuries underwent one-stage ACL and PCL reconstruction. ACL, PCL and medial collateral ligament were reconstructed in seven knees, and ACL, PCL and posterolateral structure were reconstructed in two knees. Function of the operated knee was evaluated according to the International Knee Documentation Committee (IKDC) and Lysholm scale. Anterior and posterior knee laxity was examined with a KT-2000 arthrometer. Eighteen of 19 patients were able to return for follow-up and were evaluated objectively and subjectively. The average patient age at surgery was 30.5 years, and the average postoperative follow-up was 3.5 years. No patients showed loss of knee extension more than 5 degrees , while three patients revealed loss of knee flexion more than 16 degrees . The mean postoperative total anterior-posterior side-to-side difference was 1.9 +/- 1.5 mm at 20 degrees and 2.1 +/- 1.9 mm at 70 degrees . The average of the Lysholm score was 95.1 points at the final follow-up. At the IKDC evaluation, three patients were grade A, 11 were grade B, 3 were grade C, and 1 patient was grade D. The results showed the effectiveness and safety of one-stage reconstruction of combined ligamentous injuries of the knee that can adequately restore satisfactory stability. 相似文献

Prevention of anterior cruciate ligament injuries in soccer 总被引:10,自引:0,他引:10

Proprioceptive training has been shown to reduce the incidence of ankle sprains in different sports. It can also improve rehabilitation after anterior cruciate ligament (ACL) injuries whether treated operatively or nonoperatively. Since ACL injuries lead to long absence from sports and are one of the main causes of permanent sports disability, it is essential to try to prevent them. In a prospective controlled study of 600 soccer players in 40 semiprofessional or amateur teams, we studied the possible preventive effect of a gradually increasing proprioceptive training on four different types of wobble-boards during three soccer seasons. Three hundred players were instructed to train 20 min per day with 5 different phases of increasing difficulty. The first phase consisted of balance training without any balance board; phase 2 of training on a rectangular balance board; phase 3 of training on a round board; phase 4 of training on a combined round and rectangular board; phase 5 of training on a so-called BABS board. A control group of 300 players from other, comparable teams trained normally and received no special balance training. Both groups were observed for three whole soccer seasons, and possible ACL lesions were diagnosed by clinical examination, KT-1000 measurements, magnetic resonance imaging or computed tomography, and arthroscopy. We found an incidence of 1.15 ACL injuries per team per year in the control group and 0.15 injuries per team per year in the proprioceptively trained group (P<0.001). Proprioceptive training can thus significantly reduce the incidence of ACL injuries in soccer players. 相似文献
