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.
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.
ObjectiveTo investigate the method and effectiveness of transosseous suture in situ technique in repairing anterior cruciate ligament (ACL) avulsion injury for the multiple ligament injuries with knee dislocation (MLIKD).MethodsThe clinical data of 27 patients (27 knees) with MLIKD between September 2010 and April 2016 were analyzed retrospectively. There were 21 males and 6 females, with an average age of 42 years (range, 24-60 years). The injury was caused by traffic accident in 9 cases, heavy-weight crushing in 9 cases, sports sprain in 6 cases, falling from height in 3 cases. The interval from injury to operation was 1-19 days (mean,10.8 days). There were 20 cases of femoral avulsion injury of ACL, 7 cases of tibial avulsion injury of ACL, and there were 17 cases of posterior cruciate ligament (PCL) injuries. According to the Schenck classification, there were 15 cases of KD-Ⅲ-M type, 8 cases of KD-Ⅲ-L type, and 4 cases of KD-Ⅳ type. All patients were positive in the posterior drawer test and Lachman test; 8 cases were degree Ⅲ positive in varus stress test, and 15 cases were degree Ⅲ positive in valgus stress test. The Lysholm score of knee was 27.6±6.5, the International Knee Documentation Committee (IKDC) score was 25.5±6.2, and the range of motion (ROM) of knee was (45.1±10.2)°. The injured PCL was reconstructed with a single bundle of autologous hamstring tendon. ACL was repaired with double bundle traction by transosseous suture in situ technique. Medial cruciate ligament, lateral cruciate ligament, joint capsule, and other damaged structures were repaired at the same time.ResultsAll incisions healed by first intention. There were 3 cases with joint effusion and 3 cases with incomplete flexion. All patients were followed up 12-36 months (mean, 22 months). The X-ray films showed good stability in all directions. At last follow-up, the anterior and posterior drawer tests were all negative; Lachman test was degreeⅠpositive in 4 cases, valgus stress test was degreeⅠpositive in 3 cases, varus stress test was degreeⅠpositive in 1 case; and all tests were negative in the rest patients. At 1 year after operation, the ROM of knee was (119.3 ±12.6)°, Lysholm score was 87.2±6.3, and IKDC score was 87.9±6.3, showing significant differences when compared with the preoperative scores (P<0.05).ConclusionTransosseous suture in situ technique can be used to repair the ACL avulsion injury for MLIKD, which can significantly improve the stability, mobility and function of the knee joint, and obtain satisfied short-term effectiveness.
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.
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.
Objective To investigate the evaluation, diagnosis, and surgical treatment of knee joint diagonal lesion and to observe its effectiveness. Methods A retrospective analysis was performed on 9 patients with knee joint diagonal lesion admitted between November 2011 and November 2019, including 7 males and 2 females, aged 18-61 years, with an average age of 38.3 years. According to the clinical staging criteria of multiple ligament injury of knee joint, 6 patients with acute stage injury (≤3 weeks), the time from injury to operation was 5-16 days, with an average of 9.3 days; 3 patients with old stage injury (>3 weeks), the time from injury to operation was 7, 12, 144 months, respectively. Posterolateral complex injuries were all type C according to Fanelli classification, and the posterior cruciate ligament injury was grade 3 according to American Medical Association (AMA) classification. According to the three columns classification of tibial plateau fracture, there were 2 cases of zero column fracture and 7 cases of medial column fracture. Patients with acute injury were treated with posterior cruciate ligament reconstruction, posterolateral complex repair and/or reinforcement reconstruction, and tibial plateau fracture was treated with conservative treatment or internal fixation. Patients with malunion of tibial plateau in old stage were treated with limited osteotomy, bone grafting, and internal fixation; the stability of the knee joint was further evaluated during operation, then the posterior cruciate ligament reconstruction and/or posterolateral complex repair and reconstruction were performed as needed. Lysholm score and the International Knee Documentation Committee (IKDC) score before and after operation were used to evaluate knee function and effectiveness. Results All patients were followed up 24-119 months, with an average of 51.7 months. All the incisions healed by first intention, and no complication such as incision infection, deep venous thrombosis of lower extremities occurred, and there was no reoperation during follow-up. The full-length X-ray films of both lower extremities at 6 months and 1, 2 years after operation showed that the alignment of both lower extremities returned to normal, and the stress position X-ray films showed that the stability in all directions recovered well. The X-ray films of the knee joint at 6 months after operation showed that the fracture of the tibial plateau healed well. At 1 year after operation, MRI showed that the signal of the repaired and reconstructed ligament was good, and there was no reconstruction failure such as ligament absorption or rupture occurred. At 1 year after operation, the muscle strength of the affected limbs was all rated as grade Ⅴ, and the active and passive range of motion of the knee joint recovered to 0°-130°. At 2 years after operation, the Lysholm score and IKDC score significantly improved when compared with those before operation (P<0.05). Conclusion Knee joint diagonal lesion is a special type of posterior cruciate ligament and posterolateral complex injury with anteromedial split and collapse fracture of tibial plateau, which requires correct evaluation and diagnosis of the injured structure, and detailed surgical and rehabilitation programs to achieve better effectiveness.
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.
Objective To investigate the short-term effectiveness of one-stage anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and posterolateral complex (PLC) reconstruction combined with medial collateral ligament repair for KD-Ⅳ knee dislocation. Methods Between January 2018 and June 2020, 9 patients with KD-Ⅳ knee dislocation were treated. Of 9 cases, 7 were male and 2 were female with an average age of 32.3 years (range, 23-43 years). The knee dislocation was caused by falling from height in 6 cases and traffic accident in 3 cases. The injury located at left knee in 2 cases and right knee in 7 cases. The time from injury to operation was 14-24 days, with an average of 19 days. The preoperative International Knee Joint Documentation Committee (IKDC) score was 45.6±4.2, Lysholm score was 42.4±7.0, and the knee joint active flexion range of motion was (75.2±12.3)°. The posterior drawer test, pivot-shift test, Dial test, and 0° valgus stress test were all positive. Under arthroscopy, PCL was reconstructed with the autologous tendons, ACL with allogeneic Achilles tendon, PLC with the allogeneic anterior tibial tendon by Larson enhanced reconstruction method, and MCL was repaired with anchor or simple suture. Results The operation time was 2-3 hours (mean, 2.5 hours). All incisions healed by first intention after operation. All patients were followed up12-25 months (mean, 16.1 months). After operation, 2 cases developed knee flexion disorder and pain, and 1 case had knee joint stiffness. At last follow-up, the IKDC score was 76.9±7.4, the Lysholm score was 81.6±6.4, and the knee active flexion range of motion was (122.9±7.2)°, all of which significantly improved when compared with preoperative ones (P<0.05). During follow-up, there was no failure of the grafts. At last follow-up, there were significant differences in the posterior drawer test, pivot-shift test, Dial test, and 0° valgus stress test between pre- and post-operation (P<0.05). The imaging review showed that the positions of the bone tunnels were satisfactory, the reconstructed ACL, PCL, and PLC structures were continuous, and MCL insertions were restored. Conclusion One-stage ACL, PCL, and PLC reconstruction combined with MCL repair to treat KD-Ⅳ knee dislocation can effectively restore knee joint stability, improve joint laxity, and improve joint movement.
Objective To investigate the effectiveness of personalized treatment based on Hua Xi-knee dislocation and multiple ligament injury (HX-KDMLI) diagnosis and treatment system. Methods A clinical data of 36 patients (36 knees) with KDMLI met the selective criteria between February 2019 and September 2020 was retrospectively analyzed. There were 24 males and 12 females with an average age of 45.7 years (range, 21-62 years). The KDMLI was caused by traffic accident in 15 cases, heavy pound in 8 cases, sports sprain in 7 cases, falling from height in 4 cases, and machine cutting in 2 cases. The interval between injury and operation was 1-9 weeks (mean, 3.6 weeks). All patients were categorized according to HX-KDMLI diagnosis and treatment system. Twenty patients were categorized as acute period and 16 patients as chronic period. Three patients were type HX-Ⅰ-A, 1 type HX-Ⅰ-P, 10 type HX-Ⅲ-L, 13 type HX-Ⅲ-M, 4 type HX-Ⅳ-S, 3 type HX-Ⅴ-F, and 2 type HX-Ⅴ-T. Thirty-five patients were positive in both the anterior drawer test and Lachman test, 31 were positive in the posterior drawer test; 19 patients were positive in varus stress test, 23 were positive in valgus stress test. According to the Internation Knee Documentation Committee (IKDC) grading, there was 1 case of grade A, 5 cases of grade B, 8 cases of grade C, and 2 cases of grade D. Surgical interventions included arthroscopic surgery, open surgery, or arthroscopy combined with open surgery, ligament suture or reconstruction, and internal fixation after anatomical reduction of the fracture. Different rehabilitation protocols were assigned to patients during different postoperative period, according to patient’s individualized classification. ResultsAll incisions healed by first intention with no obvious complications. All patients were followed up 12-19 months (mean, 15 months). At 12 months after operation, all patients retained muscle strength of grade Ⅴ, and range of motion of the knee joint could reach 0° extension and over 120° flexion. Radiographic examination showed no sign of knee instability, healed fractures, ideal joint alignment, good continuity and tension, and clear image of repaired or reconstructed ligaments. The anterior and posterior drawer tests were all negative. Lachman test was degreeⅠpositive in 5 cases, valgus stress test was degreeⅠpositive in 2 cases, varus stress test was degreeⅠpositive in 2 cases; the other patients were all negative. At 12 months after operation, according to the IKDC grading, there were 9 cases of grade A, 19 cases of grade B, 5 cases of grade C, and 3 cases of grade D, showing significant differences when compared with the preoperative ones (Z=–5.328, P=0.000). There were significant differences in the IKDC, Lysholm, and Tegner scores between pre- and post-operation (P<0.05). ConclusionThe promising effectiveness of KDMLI can obtain under the guidance of HX-KDMLI.
