目的 :探讨膝关节损伤中胫骨平台外侧缘撕脱骨折的特点及临床诊治。方法 :自2011年1月至2015年12月运用关节镜技术微创治疗关节内损伤结合双锚钉内固定胫骨平台外侧缘撕脱骨折29例,男17例,女12例;年龄27~62岁,平均41岁。20例合并前交叉韧带断裂(包含前交叉韧带胫骨止点撕脱骨折),3例合并后交叉韧带断裂,1例同时合并前交叉韧带和后交叉韧带断裂,3例合并侧副韧带撕裂,2例合并胫骨平台骨折(内侧平台骨折和外侧平台骨折各1例)。术前均行X线、CT及MRI检查明确诊断,在受伤后5~14 d进行手术,平均7 d。采用Lysholm膝关节评分对膝关节术前、术后功能进行评价。结果:手术时间40~125 min,平均85 min;出血量10~30 ml,平均15 ml。术后所有患者获随访,时间12~18个月,平均14个月。Lysholm膝关节评分由术前的52.0±4.2明显提高至术后1年的91.9±1.4(t=-49.24,P0.05)。抽屉试验、Lachman试验及侧方应力试验均阴性,骨折均骨性愈合。结论 :胫骨平台外侧缘撕脱骨折提示合并有膝关节静力稳定结构(关节韧带、关节囊、半月板等)的损伤,甚至关节内骨折。常规要行CT和MRI检查,建议行关节镜探查,防止漏诊,以使患者能得到及时、全面的治疗,为膝关节功能最大限度恢复创造有利条件。     

Pure Varus Injury to the Knee Joint

A 30-year-old male was involved in a car accident. Radiographs revealed a depressed marginal fracture of the medial tibial plateau and an avulsion fracture of the fibular head. Magnetic resonance imaging showed avulsion fracture of Gerdy''s tubercle, injury to the posterior cruciate ligament (PCL), posterior horn of the medial meniscus, and the attachments of the lateral collateral ligament and the biceps femoris tendon. The depressed fracture of the medial tibial plateau was elevated and stabilized using a cannulated screw and washer. The injured lateral and posterolateral corner (PLC) structures were repaired and augmented by PLC reconstruction. However, the avulsion fracture of Gerdy''s tubercle was not fixed because it was minimally displaced and the torn PCL was also not repaired or reconstructed. We present a unique case of pure varus injury to the knee joint. This case contributes to our understanding of the mechanism of knee injury and provides insight regarding appropriate treatment plans for this type of injury.     

Segond骨折及合并损伤的临床诊治分析

目的 :研究Segond骨折的手术时间与方法和临床表现特点。方法:2010年6月至2014年12月期间,收治10例Segond骨折病例,均为男性,年龄26~69岁,平均42岁。其中,伤后7~10 d行关节镜探查发现前交叉韧带完全断裂及半月板损伤6例;伤后7~10 d行关节镜探查发现前交叉韧带胫骨侧止点撕脱骨折并半月板损伤2例;伤后4~8周行关节镜探查手术2例,发现前交叉韧带及后交叉韧带同时完全断裂并半月板损伤1例,前交叉韧带完全断裂无后交叉韧带断裂1例。针对交叉韧带完全断裂的患者在关节镜探查后行交叉韧带重建术,9例半月板损伤患者给予半月板成形术或缝合术,2例前交叉韧带胫骨止点撕脱骨折的病例则在关节镜下采用爱惜邦捆绑固定技术进行复位与固定。术后采用Lysholm膝关节评分标准进行疗效评价。结果:伤后10 d手术干预的8例,膝关节在术后3 d时肿胀明显,给予关节腔穿刺发现淡血性液,术后1周开始护具保护并下床。伤后4~8周行手术处理的2例,膝关节在术后3 d时无明显肿胀,进行关节腔穿刺抽吸未发现淡血性液,术后3 d能在护具保护下活动及下床。术后10例均获随访,时间12~24个月,平均18个月。Lysholm膝关节评分术后高于术前,治疗结果满意。结论:关于Segond骨折,正确且早期诊断对治疗至关重要;Segond骨折往往伴发前交叉韧带损伤和半月板损伤,关节镜下手术(包括交叉韧带重建和半月板修复等)的最佳手术时间宜在伤后4周~2个月内进行,且需要依据不同并发症挑选个性化的治疗方案。     

Magnetic resonance imaging in the evaluation of tibial eminence fractures in adults

Proton density and T2-weighted sagittal, axial, coronal, and inversion recovery fat suppression magnetic resonance imaging (MRI) sequences were reviewed in 21 adults (10 men and 11 women) with 22 tibial eminence fractures. Average patient age was 43 years (range: 19-62 years). There were 3 type I, 3 type II, 12 type III, and 4 type IV fractures. The average fracture fragment size was 21 x 23 mm, and the average displacement was 5.5 mm (range: 0-12 mm). The MRI disclosed anterior cruciate ligament (ACL) insertional avulsions in 20 (91%), distal posterior cruciate ligament (PCL) avulsions in 4 (18%), intrasubstance ACL damage in 9 (41%), intrasubstance PCL injury in 3 (14%), medial collateral ligament (MCL) tears in 9 (41%) knees, retinacular injury in 8 (36%), posterolateral corner damage in 8 (36%), medial meniscal tears in 5 (23%), and 4 (18%) had lateral meniscal tears. Occult subchondral osseous injuries were seen in the posterolateral tibial plateau in 13 (59%) knees, anterolateral femoral condyle in 4 (18%), and posteromedial tibial plateau in 5 (23%) knees. Discrete osteochondral fractures were present in 7 (32%) knees. Significant osseous, cartilaginous, meniscal, and ligamentous damage was discovered in all patients. Based on these findings, we recommend MRI evaluation of all tibial eminence fractures to accurately detect all knee damage.

Injuries to the posterolateral aspect of the knee accompanied by compression fracture of the anterior part of the medial tibial plateau

We present 12 cases of patients with injury to the posterolateral aspect of the knee accompanied by a compression fracture of the anterior part of the medial tibial plateau. There were 11 male patients and 1 female patient with an average age of 26 years (range, 17 to 44 years). There were 4 cases of posterolateral rotatory instability and 8 cases of straight lateral instability of the knee. The size of the compression fracture was classified into 2 types, small (8 cases) and large (4 cases). Although the mechanism of injury was considered to be hyperextension and varus force, the pattern of cruciate ligament injuries varied from case to case. The following 3 questions should be considered to determine which cruciate ligament is damaged: (1) Was the ipsilateral foot fixed to the ground? (2) Was forward inertia involved? (3) Was there a direct blow to the anteromedial aspect of the tibia or to the femur? Accompanied fractures of the medial tibial plateau were considered to have been compressed by the medial femoral condyle. The size of the accompanying compression fracture varied; 7 of 8 cases with a small-type fracture had posterior cruciate ligament injuries and 3 of 4 cases with a large-type fracture had anterior cruciate ligament injuries. The size of the fracture is determined by which point of the medial tibial plateau touched the medial femoral condyle. We propose that a compression fracture of the anterior part of the medial tibial plateau indicates a coexistent posterolateral aspect injury, and that especially a small compression fracture strongly suggests an accompanying posterior cruciate ligament injury, as well.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 17, No 6 (July-August), 2001: pp 642–647     

Insufficiency fracture of the tibial plateau after anterior cruciate ligament reconstructive surgery: a case report and review of the literature

Peri-articular fractures after anterior cruciate ligament (ACL) reconstructive surgery are rare. To our knowledge, this case documents the first insufficiency fracture of the tibial plateau after ACL reconstruction, which presented three weeks after the procedure. A 25-year-old female recreational soccer player suffered an insufficiency fracture of the tibial plateau, extending 1.5 mm into the anterior wall of tibial tunnel and medial compartment under the anterior horn of medial meniscus, which presented as a diagnostic challenge. Clinically, the fracture mimicked a low-grade infection of the surgical site, while radiographically, the fracture resembled an avulsion fracture, later confirmed as a tibial tunnel fracture with computed tomography. With the ACL graft integrity not in jeopardy, four weeks of non-weightbearing and a delayed post-operative rehabilitation program was effective in allowing the fracture to heal. Good functional outcome was achieved after conservative management, with minimal loss of terminal knee extension and minimal pain at 22-month follow-up.     

Unusual combination of posterior cruciate ligament tibial avulsion fracture and Segond fracture: A case report

Introduction and importancePosterior cruciate ligament (PCL) avulsion fracture is an uncommon entity, but it poses significant morbidity to patient's knee and activities. A combination of PCL avulsion fracture with Segond fracture is rare and has not been described much before in known literature. In this case report, we present a rare case of a combination of these two injuries.Case presentationA 16-year-old cyclist who sustained left knee injury after a high-velocity fall while cycling. He fell with his anteromedial side of his left knee hitting the ground in flexion. After the fall, he felt excruciating pain and unable to bear weight. Examination revealed severe joint effusion, tenderness on posterior and lateral side of the left knee, no vascular injury and neurological deficit present. Radiographic examination revealed PCL avulsion fracture and Segond fracture. Five days after the injury, the avulsed PCL fragment and the lateral tibial plateau fragment were reduced and fixed with 3.5 mm cortical screw and washers. On the follow up, the patient stated that there is no pain on weightbearing position and after evaluated with Knee injury and Osteoarthritis Outcome Score (KOOS), the result is 90%.Clinical discussionAlthough the combination of PCL avulsion fracture and Segond fracture is rare, this pattern of injury could happen and could be considered when evaluating knee injuries.ConclusionBoth fractures need to be addressed and managed adequately to restore knee stability and prevent early joint degeneration.     

膝关节前交叉韧带胫骨止点的软组织解剖标记

背景：膝关节前交叉韧带（ACL）重建时,胫骨骨道定位不准会产生重建韧带与髁间窝的撞击或起不到维持膝关节稳定性的作用。因此,确定ACL胫骨止点的位置非常重要。目的：研究膝关节ACL胫骨止点前内束（AMB）和后外束（PLB）与软组织标记后交叉韧带（PCL）和外侧半月板前角的距离,从而明确ACL胫骨止点在胫骨平台的位置,为ACL损伤双束重建提供理论支持。方法：解剖18个膝关节尸体标本（左膝10个,右膝8个）,测量ACL中点、AMB中点、PLB中点与PCL和外侧半月板前角的距离,并分析左、右膝关节是否存在差异。结果：AMB中点与PCL和外侧半月板前角的距离分别为（15.00±3.97）mm和（19.78±4.10）mm;PLB中点与两者的距离分别为（10.17±5.56）mm和（19.50±4.40）mm;ACL中点与两者的距离分别为（12.67±4.52）mm和（19.61±3.87）mm。左右膝关节ACL中点、AMB中点、PLB中点与软组织解剖标记的距离无明显统计学差异。结论：膝关节ACL损伤行手术重建时,可采用PCL和外侧半月板前角作为定位标记。     

Simultaneous avulsion fracture of the posterior medial and posterior lateral meniscus root: a case report and review of the literature

Injuries of the meniscus roots are increasingly recognized as a serious knee joint pathology. An avulsion fracture of the meniscus root is a rare variant of this injury pattern. In this article, a case of a traumatic simultaneous avulsion fracture of both the posterior medial and posterior lateral meniscus root associated with a tear of the anterior cruciate ligament is presented. Both avulsion fractures were treated by indirect arthroscopic transtibial pullout fixation of the bony fragment. Based on the findings of our literature review, root avulsion fractures seem to be more common in young male patients after an acute trauma to the knee joint.     

Open wedge osteotomy of medial tibial condyle gives good results in management of neglected diagonal lesions of proximal tibia

BackgroundDepressed fractures of anteromedial tibial plateau are often underappreciated and treated inadequately. When these fractures are accompanied by injuries of posterior cruciate ligament and postero-lateral corner, they are called as diagonal lesions. There are very few publications on the management of such injuries in chronic stage. The purpose of our study is to describe our results in management of these neglected fractures using open wedge osteotomy of medial tibial condyle (OWOMTC).MethodsThis is a retrospective study of ten patients. KOOS score and Tegner and Lysholm score were recorded preoperatively and at three, six, twelve and twenty four months after surgery to assess the functional outcome. Medial proximal tibial angle (MPTA) and tibial slope were recorded before and after surgery.ResultsAll cases had posterior cruciate ligament (PCL) and posterolateral corner (PLC) injuries. There was no anterior cruciate ligament (ACL) injury. MPTA was corrected from mean 76.2° ± 3.7° to mean 86.4° ± 3.2°. Mean tibial slope was increased from −4° ± 3° to mean tibial slope of 7.6° ± 2.2°.Tegner and Lyshom score improved from mean of 38–88 (p < .05) at final follow-up. KOOS score improved from mean of 32–86 (p < .05) at final follow-up. Union was achieved in all the cases. None of the cases required ligament reconstruction.ConclusionsWe conclude that OWOMTC is a useful method to manage neglected depressed fractures of anteromedial tibial plateau accompanied by PCL and PLC injury (diagonal injury). This procedure can restore limb alignment, congruency and stability of knee joint without any soft tissue reconstruction and change in the patellofemoral kinematics.

Correlation of parameters on preoperative CT images with intra-articular soft-tissue injuries in acute tibial plateau fractures: A review of 132 patients receiving ARIF

IntroductionTibial plateau fractures often occur in conjunction with soft-tissue injuries of knees. The hypothesis of this study is that parameters of CT imaging can predict intra-articular soft-tissue injuries.Patients and methodsPatients who underwent arthroscopically assisted reduction and internal fixation (ARIF) for acute tibial plateau fractures performed by a single orthopedic surgeon between 2005 and 2015 were included in this retrospective study. Patients with concomitant ipsilateral femoral fractures, who had received revision surgery or who had undergone index surgery more than 30 days from the event were excluded. We measured lateral plateau depression and widening, medial plateau depression and displacement, and column involvement observed on preoperative CT scans. Intra-articular soft-tissue injuries were diagnosed based on findings from knee arthroscopy. The correlation of imaging parameters with soft-tissue injuries was analyzed by the area under a receiver operating characteristic (AUROC) curve and multivariate logistic regression.ResultsOne-hundred and thirty-two patients were enrolled in the study. The average age was 45.7 ± 13.1 years (range: 18–75 years). Lateral tibial plateau depressions >11 mm were significantly associated with increased risk of lateral meniscus tears (p = 0.001). However, there was no significant threshold of lateral tibial plateau widening that could be used to predict lateral meniscus tear. Greater risk of anterior cruciate ligament (ACL) avulsion fracture was observed in younger patients, patients with high-energy-pattern tibial plateau fractures, patients with fractures involving anteromedial or posterolateral columns, and patients with medial tibial plateau displacement >3 mm (p < 0.05).ConclusionMeasuring lateral tibial plateau depression and column involvement on preoperative CT scans can help predict a higher risk of lateral meniscus tear and ACL avulsion fracture respectively in patients with acute tibial plateau fractures.     

膝关节后交叉韧带损伤的临床流行病学分析

目的:研究膝关节后交叉韧带损伤的临床特点及其分布规律.方法:回顾性分析2006年1月至2013年6月确诊的326例膝关节后交叉韧带损伤患者临床资料,将病例按损伤类型分组,对性别、侧别、年龄、受伤原因、受伤至就诊时间、合并损伤等因素进行分析,同时比较不同类型后交叉韧带损伤的个体化因素及合并损伤情况.结果:后交叉韧带损伤患者男性占73％,30～50岁是发病高峰(59％),患者多于伤后1个月内就诊(62.6％);受伤原因以交通伤为主(59％);合并损伤中前交叉韧带损伤最多(46.9％),其次为内侧副韧带(29.8％)和后外侧角(26.1％);后交叉韧带实质部损伤较止点撕脱骨折多,发生合并损伤的概率也较后者高(P＜0.05),受伤原因差异也具有统计学意义(P＜0.05);单纯止点撕脱骨折与单纯实质部损伤在发生率和就诊时间方面差异具有统计学意义(P＜0.05).结论:后交叉韧带损伤以实质部损伤为主,合并损伤率较高,以ACL损伤最常见;止点撕脱骨折以胫骨侧为主,多由低能量暴力导致,合并损伤较少;实质部损伤多由高能量暴力所致,多有合并损伤;单纯止点撕脱骨折发病率较单纯实质部损伤高.     

Ruptur des vorderen Kreuzbands

Rupture of the anterior cruciate ligament (ACL) is the most common ligamentous knee injury. The knee is stabilized by the cruciate ligaments and the collateral ligaments. The ACL originates from the inner surface of the lateral condyle of the femur, runs in an anterior medial direction and inserts at the tibial plateau in the intercondyle area. The most common injury is an indirect knee trauma, typically a joint torsion in sports. Patients often describe a snapping noise followed by hemarthrosis. Concomitant injuries are lesions of the medial collateral ligament, the medial meniscus (unhappy triad) and chondral fractures. The age peak is between 15 and 30 years with a higher incidence in females. The cardinal symptom of the ACL rupture is the giving way phenomenon. The clinical diagnosis is provided by a positive Lachman test, a positive pivot shift test and the anterior drawer test. Fractures can be excluded by X-ray examination. Magnetic resonance imaging (MRI) allows the evaluation of the internal knee structures. ACL repair is carried out by arthroscopically assisted bone-tendon-bone or semitendinosus grafting techniques. Early rehabilitation is important for a good functional outcome.     

Arthroskopische Wiederherstellung einer Ausrissfraktur des hinteren Kreuzbands am Tibiaansatz

Avulsion fracture of the tibial insertion of the posterior cruciate ligament (PCL) is a rare condition. Until recently, bony avulsion fractures of the PCL have been repaired with open reduction and internal fixation. Posterior approach commonly used for open repair is rather extensive, yet it does not allow for detection and managment of associated intraarticular injuries of the knee. We report a case of avulsion fracture of the tibial attachment of the PCL managed by arthroscopic reduction and fixation. A large bony fragment that extended into the posterior part of the lateral tibial plateau allowed for reduction and retrograde fixation through anterior portals only.     

Proximal avulsion of five ligaments and revised diagonal principle in tibial plateau fractures

PurposeThe aim of the study was to analyze the incidence of proximal avulsion of the five main ligaments and to revise the diagonal tension/compression concept in tibial plateau fractures.MethodsComputed tomographic images of 1263 cases of tibial plateau fractures were retrospectively analyzed by the OTA/AO classification and four-column nine-segment classification. The correlation between proximal avulsion of five ligaments and the injury mechanism was analyzed.ResultsIn total, 1263 tibial plateau fractures in 1253 patients were included. A total of 92 cases (7.3%) associated with proximal avulsions were identified among the 1263 tibial plateau fracture cases obtained from our institution's database. The 92 avulsions occurred in 82 patients, among whom 10 patients had two different avulsions in a single knee. The incidence of proximal avulsion fracture of the medial and lateral collateral ligament was 3.6% (45/1263) and 2.1% (26/1263), respectively. The incidence of avulsion of the anterior cruciate ligament and avulsion of the posterior cruciate ligament was much lower at 0.2% (2/1263) and 0.1% (1/1263), respectively. Proximal avulsion of the patellar ligament occurred in 18 cases (incidence rate = 1.4%). Several combinations of injuries, composed of distal tibial plateau fractures and proximal avulsion of ligaments, were identified.ConclusionsAmong the patients with tibial plateau fracture, the incidence of proximal avulsion of the five ligaments was 7.3% (92/1263). The four-column and nine-segment classification is an exhaustive method for recording injuries in these ligaments. The revised diagonal injury concept is useful for understanding the injury mechanism and choosing the appropriate surgical strategy.     

The incidence of soft tissue injury in operative tibial plateau fractures: a magnetic resonance imaging analysis of 103 patients

OBJECTIVES: The goal of this study was to determine the incidence of injury to soft tissue structures of the knee in tibial plateau fractures scheduled for surgery. DESIGN: Prospective cohort. SETTING: Level I academic medical center. PATIENTS/PARTICIPANTS: One hundred three consecutive patients with acute tibial plateau fractures indicated for operative intervention. INTERVENTION: Standard x-ray examinations, including anteroposterior, lateral, and oblique views, were performed in the emergency department. Subsequently all patients had magnetic resonance imaging performed. The Schatzker and AO/OTA classifications were used to classify each fracture pattern based solely on the x-rays. Soft tissue injuries were assessed by magnetic resonance imaging. MAIN OUTCOME MEASUREMENTS: Fifteen categories of injury were determined as positive or negative on each magnetic resonance imaging, which included tears of the cruciates, collateral ligaments, menisci, and posterolateral corner. RESULTS: The overall incidence of injury to soft tissues was higher than previously reported. Only 1 patient (1%) in the series had complete absence of any soft tissue injury. Seventy-nine patients (77%) sustained a complete tear or avulsion of 1 or more cruciate or collateral ligaments. Ninety-four patients (91%) had evidence of lateral meniscus pathology. Forty-five patients (44%) had medial meniscus tears. Seventy patients (68%) had tears of 1 or more of the posterolateral corner structures of the knee. The most frequent fracture pattern was a lateral plateau split-depression (Schatzker II) (60%). No pure depression injuries (Schatzker III, AO/OTA 41-B2) were seen. CONCLUSIONS: The incidence of complete ligamentous or meniscal disruption associated with operative tibial plateau fractures was higher than previously reported. Though the clinical importance of injury to each of these structures is unknown, the treating surgeon should be aware that a variety of soft tissue injuries are common in these fractures. In addition, all fractures had at least 1 cortical split visible on magnetic resonance imaging, implying that pure depression patterns are very rare or may not exist.     

Segond骨折的诊治分析

目的：探讨Segond骨折的临床特点和手术治疗的方法与时机。方法：自2008年6月至2011年12月收治16例Segond骨折,6例于伤后1周内行关节镜探查发现前交叉韧带完全断裂,半月板损伤;10例于伤后8～10周行关节镜探查,发现4例前后交叉韧带完全断裂,4例前交叉韧带完全断裂,2例前交叉韧带部分断裂,其中前交叉韧带完全断裂的8例合并半月板损伤,前交叉韧带不全断裂的1例半月板未见明显损伤,1例合并腓骨头骨折与外侧副韧带损伤。所有交叉韧带完全断裂和不全断裂的患者在关节镜探查后行交叉韧带重建术,5例半月板损伤患者行半月板缝合或成形术。术后采用Lysholm—Gillquist膝关节评分进行疗效评定。结果：伤后1周内行手术治疗的6例术后3d时膝关节肿胀明显,关节腔穿刺抽吸有淡血性液抽出,术后1周时始佩戴护具下床活动。伤后8-10周内行手术治疗的10例术后3d时膝关节无明显肿胀,关节腔穿刺抽吸无淡血性液抽出,术后3d即佩戴护具下床活动。所有患者术后获随访,时间12—50个月,平均24个月。术后Lysholm—Gillquist膝关节评分高于术前。所有病例获得满意效果。结论：Segond骨折常合并前交叉韧带损伤和半月板损伤,早期正确诊断对治疗十分重要,关节镜下行交叉韧带重建及半月板修复的最佳手术时间宜在术后8-10周内进行。
