  • ANATOMICAL RECONSTRUCTION OF POSTEROLATERAL COMPLEX IN TREATMENT OF MULTI-LIGAMENT INJURY OF KNEES

    Objective To evaluate the short-term effectiveness after static anatomical reconstruction of posterolateral complex (PLC) in the treatment of traumatic multi-ligament injury of the knee. Methods Between June 2007 and July 2011, 23 cases of multi-ligament injury of the knee were treated. There were 15 males and 8 females with an average age of 41 years (range, 19-56 years). The injury was caused by traffic accident in 9 cases, sprain in 7 cases, bruise in 3 cases, and falling from height in 4 cases. The time between injury and operation was 13-78 days (mean, 32 days). The results of posterior drawer test and Lachman test were positive, and all cases complicated by varus and external rotation instability. The Lysholm score of the knee was 43.4 ± 5.7. According to International Knee Documentation Committee (IKDC) scoring, all were rated as grade D. According to Fanelli typing, all were classified as type C. The X-ray films showed that load-induced posterior motion of the knee was (13.3 ± 4.2) mm; the lateral joint space was (15.1 ± 2.4) mm. Anterior cruciate ligament/posterior cruciate ligament and PLC were reconstructed simultaneously with auto-semitendinosus, gracilis tendon, and allogeneic tendon. Results All incisions healed by first intention, and no complication occurred. All patients were followed up 12-56 months (mean, 28 months). At last follow-up, the results of posterior drawer test and Lachman test were negative; 3 cases had varus instability, and 2 cases had external rotation instability. The Lysholm score of the knee was 85.6 ± 16.7, showing significant difference when compared with preoperative score (t=11.469, P=0.000). According to IKDC scoring, 7 cases were rated as grade A, 12 as grade B, and 4 as grade C; significant difference was found when compared with preoperative value (Z=4.285, P=0.000). The load-induced posterior motion of the knee was (5.1 ± 4.4) mm, the lateral joint space was (3.2 ± 2.8) mm, showing significant differences when compared with preoperative ones (P lt; 0.05). Conclusion In the treatment of traumatic multi-ligament injury of the knee, the anatomical reconstruction of the PLC using auto-semitendinosus, gracilis tendon, or allogeneic tendon can obtain good short-term effectiveness.

    Objective To investigate the method and the short term cl inical effectiveness of in situ suture repair procedure of knee dislocation with multi ple-l igament injury at acute stage. Methods From February 2006 to November 2007, 9 patients suffering from single knee closed dislocation with multi ple-ligament injury underwent open in situ suture repairprocedure with non-absorbable thread and managements of other combined injuries simultaneously. Nine patients included 6 males and 3 females, aged 34-52 years old. The injured knees were left side in 4 cases and right side in 5 cases. Injuries were caused by traffic accident in 8 cases and heavy-weight crushing in 1 case. EMRI and arthroscopic examination showed that all patients suffered from the avulsion injuries of anterior cruciate l igament and posterior cruciate l igament. The time from injury to operation was 4 to 7 days with an average of 5.1 days. Results No bacterial arthritis occurred after operation. Subcutaneous liquated fat occurred and cured after symptomatic treatment in 2 cases, other incisions healed by first intension. All patients were followed up 12 months. At 12 months postoperatively, 2 patients’ flexion range of the suffering knees lost 10° when to compared with normal knees, and the range of motion was from 0 to 125°. The Lysholm knee scores were 83-92 (average 86.3), the results were excellent in 3 cases and good in 6 cases. The posterior drawer test and anterior drawer test were one-degree positive in 3 cases respectively; the Lachman tests were one-degree positive in 5 cases, lateral stress tests were negative in all cases. Conclusion In situ suture repair procedure of knee dislocation with multi ple-ligament injury at acute stage has the advantages such as rel iable fixation, simultaneous management of other combined injuries and satisfactory short term effect.

  • CLINICAL EFFECT OF ARTHROSCOPICALLY ASSISTED REPAIR AND RECONSTRUCTION FOR DISLOCATIONOF THE KNEE WITH MULTIPLE LIGAMENT INJURIES

    【Abstract】 Objective To investigate the cl inical outcomes of the treatment of knee dislocation with multiplel igaments injuries by anterior cruciate l igament (ACL) and posterior cruciate l igament (PCL) reconstruction underarthroscopy and repair of the injured structures of the knee joint. Methods From July 2003 to August 2006, there were24 patients with knee dislocation (19 males and 5 females), with the average age of 42 years (ranging from 20 years to 69years), whose ACL and PCL were reconstructed under arthroscopy and whose collateral l igaments and other structures of the knee were repaired [8 with injuries of ACL, PCL, medial collateral l igament (MCL) and lateral collateral l igament (LCL); 12 with injuries of ACL, PCL and MCL; 4 with injuries of ACL, PCL and LCL]. There were 1 case with common peroneal nerve injury, 3 with medial meniscus injury and 7 with lateral meniscus injury. Every patient had single knee dislocation. The outcome was measured from the following aspects: range of the knee, compl ication, cl inical improvement and Lysholm scoring. Results Twenty-four patients were followed up for 11 months to 36 months, with the average time of 25 months.Eleven patients (45.8%) recovered to the normal sports level and 13 (54.2%) patients’ knee function improved significantly so that they could walk by themselves. Lachman test, anterior drawer test and posterior drawer test were negative in 24 patients. The side-to-side difference was less than 5 mm in 24 patients. There were 4 patients who had sl ight knee stiffness. One patient’ s feel ing and sports function of the general peroneal nerve improved to the normal level. Lysholm scale of the knee function was 41.8 ± 4.3 preoperatively and 87.0 ± 6.0 postoperatively (P lt; 0.05). The movement ranges of the knee were (87.5 ± 12.5)° preoperatively and (125.0 ± 9.2)° postoperatively (P lt; 0.05). Conclusion Reconstructing the ACL and PCL and repairing other structures of the knee is an effective method to treat dislocation of the knee.

  • EFFECTIVENESS OF ONE-STAGE REPAIR AND RECONSTRUCTION OF TRAUMATIC DISLOCATION OF KNEE JOINT COMBINED WITH MULTIPLE LIGAMENT INJURIES

    ObjectiveTo investigate the effectiveness of one-stage repair and reconstruction of multiple ligament injuries of the knee under arthroscopy. MethodsBetween March 2007 and March 2009,25 patients (25 knees) with multiple ligament injuries of the knee underwent one-stage repair and reconstruction under arthroscopy.Of 25 cases,16 were male and 9 were female with an average age of 29.6 years (range,18-43 years).The causes of injury were traffic accident injury in 20 cases,falling injury from height in 3 cases,and sport injury in 2 cases.The time between injury and surgery was 8-14 days (mean,10.5 days).The preoperative Lysholm score was 37.92±3.57.The X-ray film and MRI examinations showed that 17 patients had tears of anterior cruciate ligament (ACL),posterior cruciate ligament (PCL),and medial collateral ligament,and 8 patients had tears of ACL,PCL,and posterolateral corner (PLC);5 cases had medial meniscus injury and 7 cases had lateral meniscus injury.The ACL,PCL,and PLC were reconstructed under arthroscopy with autologous tendon or allogeneic tendon,and the MCL was repaired.Early active and passive functional exercises were done postoperatively. ResultsAll the incisions healed by first intention,and there was no complications of infection and deep venous thrombosis.Twenty-five patients were followed up 24-78 months (mean,50.9 months).Six patients had knee stiff postoperatively;after manipulation under anesthsia,5 patients lost less than 15° of flexion and only 1 patient lost 26° of flexion.At last follow-up,the stability of the knee joint was significantly improved.There were significant differences in the anterior drawer test,posterior drawer test,Lachman test,and varus stress and valgus stress testing at 30° between at last follow-up and at preoperation (P<0.05).The postoperative Lysholm score was 87.84±4.85,which was significantly better than the preoperative score (t=52.053,P=0.000).The International Knee Documentation Committee (IKDC) rating was nearly normal in 16 cases (64%),abnormal in 8 cases (32%),and obviously abnormal in 1 case (4%). ConclusionOne-stage repair and reconstruction of multiple ligament injuries of the knee under arthroscopy can effectively restore the function of the knee joint,and the effectiveness is reliable.

  • EFFECTIVENESS OF ONE-STAGE REPAIR AND RECONSTRUCTION FOR KNEE DISLOCATION WITH MULTIPLE LIGAMENT INJURIES

    Objective To evaluate the surgical procedure and short-term effectiveness of one-stage repair and reconstruction of knee dislocation with multiple ligament injuries (KDMLI). Methods Between September 2010 and April 2014, 9 cases (9 knees) of KDMLI were treated. There were 7 males and 2 females with an average age of 42 years (range, 27-57 years). Injury was caused by traffic accident in 3 cases, heavy-weight crushing in 3 cases, sports sprain in 2 cases, and falling from height in 1 case. The average time from injury to operation was 11 days (range, 3-19 days). The results of posterior drawer test and Lachman test were positive in all patients. The results of varus stress testing were three-degree positive in 4 cases, and the results of valgus stress testing were three-degree positive in 6 cases. The Lysholm score of knee was 27.2±6.3; the International Knee Documentation Committee (IKDC) score was 29.7±6.5; and the range of motion (ROM) was (52.6±12.8)°. All patients suffered from posterior cruciate ligament (PCL) injury and femoral avulsion injury of anterior cruciate ligament (ACL). Combined injuries included medial collateral ligament (MCL) injury in 4 cases (medial meniscus injury in 1 case), lateral collateral ligament (LCL) injury in 2 cases, and MCL and LCL injuries in 2 cases (medial meniscus and lateral meniscus injuries in 1 case). Autologous harmstring tendon was used to reconstruct PCL under arthroscopy combined with limited open in situ suture for repair of femoral avulsion injury of ACL, and repair of MCL, LCL, and other injury in one-stage operation. Results All incisions healed by first intention. Joint effusion of knee occurred in 1 case and was cured after removal of fluid combined with pressure bandage. All patients were followed up 12-36 months with an average of 22 months. At last follow-up, the result of posterior drawer test was negative in all patients. The results of Lachman test were one-degree positive in 2 cases; the result of varus stress testing was one-degree positive in 1 case; the results of valgus stress testing were one-degree positive in 2 cases; and flexion dysfunction of the knee was observed in 1 case. The Lysholm score of knee was 87.3±6.6; the IKDC score was 88.9±6.8; and the ROM was (121.7±12.3)°, all showing significant differences when compared with preoperative ones (t=44.246, P=0.000; t=37.903, P=0.000; t=19.894, P=0.000). Conclusion For KDMLI, one-stage repair and reconstruction using autologous harmstring tendon to reconst ruct PCL under arthroscopy combined with limited open in situ suture repair of femoral avulsion injury of ACL, and repair MCL, LCL, and other injury has such advantages as minimal invasiveness, reliable fixation, less complications, and fast recovery, which can significantly improve the stability, ROM, and function of knee and obtain good short-term effectiveness.

  • TREATMENT OF SEVERE MEDIAL COLLATERAL LIGAMENT RUPTURE IN MULTI-LIGAMENT INJURY

    ObjectiveTo compare the clinical efficacy between medial collateral ligament (MCL) repair and MCL reconstruction in multi-ligament injury. MethodsThirty-one patients with MCL rupture and multi-ligament injury of knee joint were treated between August 2008 and August 2012, and the clinical data were retrospectively analyzed. Of 31 patients, 11 cases underwent MCL repair (repair group), and 20 cases underwent MCL reconstruction (reconstruction group). There was no significant difference in gender, age, body mass, injury side, injury cause, and preoperative knee Lyshlom score, International Knee Documentation Committee (IKDC) subjective score, range of motion, and medial joint opening between 2 groups (P > 0.05). The postoperative knee subjective function and stability were compared between 2 groups. ResultsAll incisions healed by first intention, and no postoperative complication occurred. All patients were followed up 2-4 years (mean, 3.2 years). At 2 years after operation, the IKDC subjective score, Lyshlom score, and range of motion were significantly increased in 2 groups when compared with preoperative ones (P < 0.05). The range of motion of reconstruction group was significantly better than that of repair group (P < 0.05). No significant difference was found in IKDC subjective score and Lyshlom score between 2 groups (P > 0.05). The medial joint opening was significantly improved in 2 groups at 2 years after operation when compared with preoperative one (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). ConclusionBoth the MCL reconstruction and MCL repair can restore medial stability in multi-ligament injury, but MCL reconstruction is better than MCL repair in range of motion.

  • Association of surgical timing and operative outcomes in multiple ligaments knee injuries: a meta-analysis

    ObjectivesTo systematically review the differences of operative outcomes between early surgery and delayed surgery in multiple ligament injury of knee joint (MLIK) patients.MethodsPubMed, The Cochrane Library, EMbase, CNKI, CBM, WanFang Data and VIP databases were searched to collect cohort studies about operative outcomes of different surgery times in MLIK patients from inception to September 23rd, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 8 cohort studies involving 153 early and 90 delayed operatively treated patients were included. The results of meta-analysis showed that: compared with delayed surgery, early surgery received higher Lysholm score (MD=7.52, 95%CI 2.00 to 13.04, P=0.008) and superior IKDC score rate (OR=2.97, 95%CI 1.51 to 5.84, P=0.002). There were no significant differences in Tegner score (MD=–0.08, 95%CI –1.07 to 0.92, P=0.88) and ROM (MD=4.08, 95%CI –2.38 to 10.55, P=0.22) between two groups. The main adverse reactions of MLIK included neurovascular injury, deep venous thrombosis of lower extremities, common peroneal nerve injury, tourniquet paralysis and limited joint activity. Early surgery had a lower incidence of complications than delayed surgery (7.1% vs. 30%).ConclusionThe current evidence shows that early surgery can receive higher Lysholm score and superior IKDC score rate in treatment of MLIK, and have a lower incidence of complications. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.

  • Application of high tibial osteotomy for chronic multi-ligament knee injury associated with lower extremity malalignment

    Objective To investigate the feasibility and effectiveness of high tibial osteotomy (HTO) in treatment of chronic multi-ligament knee injury (MLKI) associated with lower extremity malalignment. Methods A clinical data of 14 patients (14 knees) of chronic MLKI associated with lower extremity malalignment, who were treated with HTO between January 2016 and September 2020, was retrospectively analyzed. There were 10 males and 4 females, with an average age of 30.5 years (range, 22-48 years). The causes of injury included traffic accident in 8 cases, bruising by a heavy object in 3 cases, falling from height in 2 cases, and twisting in 1 case. According to Schenck classification of knee dislocation (KD), there were 4 cases of KD-Ⅰ [2 cases of anterior cruciate ligament (ACL) and posterolateral complex (PLC) injuries and 2 cases of posterior cruciate ligament (PCL) and PLC injuries], 7 cases of KD-Ⅲ (all of ACL, PCL, and PLC injuries), and 3 cases of KD-Ⅳ. The preoperative hip-knee-ankle angle (HKA) was (167.1±4.7)°, and the posterior tibial slope angle (PTSA) was (16.3±2.7)°. The knee joint was severely unstable and the patients could not stand and walk normally. Among them, 5 cases of medial compartment cartilage were severely worn out (3 cases of Kellgren-Lawrence grading Ⅱ, 2 cases of grading Ⅲ) causing pain. After admission, 2 cases of KD-Ⅰ underwent HTO and ligament reconstruction in the first stage, 1 case of KD-Ⅲ and 1 case of KD-Ⅳ underwent HTO in the first stage and ligament reconstruction in the second stage; the remaining 10 patients only underwent HTO. Results All patients were followed up 12-50 months, with an average of 30 months. The incisions healed by first intention after operation, and no complications such as infection and deep vein thrombosis of the lower extremities occurred. At 12 months after operation, knee range of extension was –5°-0° (mean, –1.2°) and range of flexion was 110°-140° (mean, 125.5°). The Lachman test was negative in 11 cases and positive in 3 cases. The posterior drawer test was negative in 9 cases and positive in 5 cases. The 0/30° varus stress test was negative in 10 cases and positive in 4 cases. The 0/30° valgus stress test was negative in 13 cases and positive in 1 case. The visual analogue scale (VAS) score was significantly lower than that before operation (P<0.05), and the International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score were all significantly higher than those before operation (P<0.05). The X-ray film reexamination at 12 months after operation showed that the HKA was (178.2±3.8)° and the PTSA was (8.6±2.4)°, which were significantly different from those before operation (P<0.05). All osteotomies achieved bone union, and the healing time was 3-11 months, with an average of 6.8 months. Conclusion For chronic MLKI associated with lower extremity malalignment, HTO can restore normal lower extremity alignment and improve knee joint function, which is a feasible salvage operation.
