Objective: To explore the clinical characteristic of the multiple-ligament injured knee and evaluate the protocol, technique and outcome of treatment for the multipleligament injured knee. Methods: From October 2001 to March 2005, 9 knees with combined anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) tears in 9 patients were identified with clinical and arthroscopic examinations. Of them, 5 knees were combined with ruptures of posteromedial corner (PMC) and medial collateral ligament (MCL), 4 with disruptions of posterolateral corner (PLC), 2 with popliteal vascular injuries and 1 with peroneal nerve injuries. Six patients were hospitalized in acute phase of trauma,2 received repairs of popliteal artery and 4 had repairs of PMC and MCL. Reconstructions of ACL and PCL with autografts under arthroscope were performed in all patients at 4 to 10 weeks after trauma, including reconstruction of PLC with the posterior half of biceps femoris tendon tenodesis in 4 patients and reconstructions of PMC and MCL with femoral fascia in 1 patient. Results: No severe complications occurred at early stage after operation in the 9 patients. All of them were followed up for 10-39 months with an average of 23. 00 months±9. 46 months. Lysholm score was 70-95 with an average of 85.00±8.29. International Knee Documentation Committee (IKDC) score was from severely abnormal (Grade D) in 9 knees at initial examination to normal (Grade A) in 2 knees, nearly normal (Grade B) in 6 knees and abnormal in 1 knee at the last follow-up. Of the 9 patients, 7 returned to the same activity level before injury and 2 were under the level. Conclusions:The multiple-ligament injured knee with severe instability is usually combined with other important structure damages. Therefore, careful assessment and treatment of the combined injuries are essential. Reconstructions of ACL and PCL under arthroscope, combined with repairs or reconstructions of the extraarticular ligaments simultaneously or in stages, have advantage of minimal trauma in surgery and satisfactory outcome.  相似文献

Objective: To evaluate the therapeutic effect of combined reconstruction of anterior cruciate ligament ( ACL ) and posterior cruciate ligament ( PCL ) simultaneously by using allograft patellar tendon under arthroscopy. Methods: From May 2003 to November 2005, 10 cases of ruptured ACL and PCL were fixated with compressed screws and reconstructed under arthroscopy with allograft patellar tendon simultaneously. The clinical results were evaluated according to IKDC, Lysholm, and Tegner clinical rating scales. Results. All patients were followed up for 12-30 months (mean: 18 months ). At the last follow-up, there was no knee extension limitation and knee flexion was between 120° and 135°, with an average of 128.38°. The Lysholm score of the 10 cases was 66. 5 ± 5. 6 before operation and 89.8 ± 3.4 at last follow up. The difference was statistically significant ( P 〈 0.01 ). The average Tegner activity score decreased from 6.9 ± 1.7 ( range : 4-9 ) before injury to 5.5 ± 1. 6 (rang: 2-9) at the follow-up (P=0.53). At the end of follow-up, IKDC score was graded as A in 4 cases (40.0 % ), B in 5 (50.0 % ), and C in 1 (10.0%). Of the 10 patients, 8 returned to the same sports level as before injury and 2 were under the level. Conclusion. Arthroscopic combined reconstruction of ACL and PCL with allograft patellar tendon has the advantages of minimal trauma in surgery and reliable satisfactory outcome.  相似文献

Objective: To evaluate the clinical outcome of arthroscopically assisted combined anterior and posterior cruciate ligament (ACL/PCL) reconstructions using Achilles tendon-bone allografts.
Methods: Associated meniscus injuries were treated according to established methods prior to ligament reconstructions during arthroscopic surgery. Thirty Achilles tendon-bone allografts were used to reconstruct torn ACL and PCL in 15 knees. At postoperative follow-up, all knees were graded using the modified IKDC and the Lysholm scoring systems just as done preoperatively. Results were analyzed compared with the contralateral healthy knees.
Results: Eleven men and 4 women with a minimum of 3-year follow-up (mean 38 months) were included in the study. Preoperatively, the group ratings by the modified IKDC standards were all severely abnormal. Twelvebicruciate reconstructions were performed in subacute or chronic stage (〉3-8 weeks), 3 for acute ligamentous deficiencies (≤ 3 weeks). The noticeable early complication was transitory local fever combined with joint effusion in one case. At postoperative follow-up, 9 knees were normal, 5 nearly normal and 1 abnormal. On Lysholm score the difference was statistically significant (ttest, P〈0.001) before and after operation. Conclusions: Achilles tendon-bone allograft offers an alternative for simultaneous arthroscopic ACL/PCL reconstructions. However, further investigation is needed to eradicate its potential immunogenicity for better use.  相似文献

Objective To discuss the minimal invasive arthroscopic surgery technique and clinical results of both the medial and lateral meniscal transplantation following the anterior cruciate ligament reconstruction with double bundles and bone tunnels.Methods In August 2008 a minimal invasive surgery of both the medial and lateral meniscal allograft transplantation following anterior cruciate ligament reconstruction was preformed for 1 case with both the medial and lateral menicectomy by arthroscopic surgery.The method of two bone plugs attached on tibial plateau was employed for medial meniscal allograft transplantation and the technique the bridge in slot for lateral meniscal allograft transplantation.The VAS,Lysholm score and IKDC rating were recorded before and after operation.The stability of knee was assessed by Lachman test,drawer sign and pivot shift test.Results The patient was followed up 26 month after the operations.The degrees of knee flexion,extension and function of walk were normal.The Lachman test,drawer sign and pivot shift test were nearly normal.The VAS after operation was 2 points lower than that before operation.The Lysholm score post-operation was 20 points higher than pre-operation.The IKDC became B degree in late following-up from C degree before the operation.MRI revealed anterior cruciate ligament graft was continuous and the meniscal allograft was normal shape on year 1 after the operation.The posterior horn of medial meniscal allograft and anterior corner of lateral meniscal allograft showed slightly shrunk.The second-look arthroscopy showed that the healing occurring between meniscal allograft and the capsule and meniscal allograft was normal shape on month 18 after the operation.The anterior horn of medial and lateral meniscus was slightly worn.Conclusions Both the medial and lateral meniscal transplantation following the anterior cruciate ligament reconstruction in appropriately selected patients with the medial and lateral meniscus-deficient knee may recover the knee mechanic balance and stability,which is a option of treatment for that young and activity patients.It is proposed that the medial and lateral meniscal grafts harvested from a single donator.Attention should be paid to the direction of the bone tunnels fixing the horns of the meniscus in order to avoid communication with the tunnels of anterior cruciate ligament reconstruction.  相似文献

Abstract:
Objective To evaluate the clinical significance of arthroscopic anterior cruciate ligament (ACL)reconstruction using the remnant-preserved technique.Methods From August 2008 to September 2009,70 cases with the remnant of injured ACL were included in the trials,which were randomized into the remnant preservation(RP)group and the control group,35 cases in each group.All patients in the two groups underwent arthroscopic ACL reconstruction surgeries,with ACL-remnant preserving technique in RP group and ACL-remnant resection in control group,respectively.The injured ACL was reconstructed with allograft in all cases.Postoperative follow-up assessment included the International Knee Documentation Committee(IKDC)grading and Lysholm score,Lachman test,pivot shift test and KT-1000 measurement,proprioception measurements and the arthroscopic second look evaluation.Results Sixty-one(61/70,87%)cases were available for an average of 13.1 months follow-up assessment postoperatively.There were no significant differences between the RP and control group in functional outcome as evaluated with Lysholm score(96.4 vs.94.9,P = 0.71)and IKDC grading(cases with A and B gradings:30 vs.29,P = 0.586).Regarding objective stability,there were no differences between the 2 group in mean side-to-side difference of KT-1000(1.69 mm vs.1.65 mm,P =0.83),Lachman test(negative cases:29 vs.28,P = 1.00)and pivot shift test(negative cases:31 vs.27,P =0.225).There was also no difference between the groups in proprioception evaluation measured with angle repetitive test(4.56°vs.4.28°,P=0.522).During second look arthroscopic examination,the grafts synoveal coverage rates were found to be 85% in the RP group and 84.2% in the control group,without significant difference(P>0.05).Conclusions Arthroscopic ACL reconstruction with the remnant preserving technique using tendon allograft do not improve the postoperative knee-joint function scores,stability,proprioception and synovial coverage of grafts.  相似文献

Objective To investigate the clinical results of posterior cruciate ligament (PCL) reconstruction by double bundle-double tunnel Y-shape of the anterior tibialis tendon allograft. Methods From March 2001 to January 2008, 47 patients underwent PCL reconstruction were included. The allogeneic adult anterior tibialis tendon was prepared into the Y-shape double bundles with the length of 130 mm; A bundle was defined as A-side; B-side was two short bundle (B1, B2 bundle). A bundle was 70 mm in length with a diameter of 10-12 mm. B1 bundle (anterolateral bundle) was 55 mm long with a diameter of 6 mm; B2 bundle(posteromedial bundle) was about 50 mm with a diameter of 6 mm. The allograft ligament was installed through the antero-medial approach. Absorbable interface screws were fixed in the tibial tunnel firstly, and then in the femoral tundles. When being fixed, anterolateral bundle was in flexion of 90°, postero-medial bundle was in 30°. Assisted exercise with knee an angle-locked walking aid had continued for 8-10 weeks. Results The average operating time were 45 min. The average follow-up time was 49.5 months. Preoperative Lachmann was positive in all cases while Lachmann was negative in 39 cases, weakly positive in 5 cases, and positive in 4 cases postoperatively. Post-operative KT-1000 testing, Lysholm score and Tegner activity levels has improved significantly compare with the pre-operative ones. Conclusion The double folded bundles of adult anterior tibialis tendon has sufficient length and diameter for posterior cruciate ligament reconstruction with power tension. The methods of ligament passing through the tunnel has improved to ease the procedure.  相似文献
