[PMID: 32732120 DOI: 10.1016/j.injury.2020.07.046] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 07/11/2020] [Accepted: 07/20/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Popliteal artery injuries are rare. They have high amputation rates. OBJECTIVES To report our experience, identify predictors of outcome; mechanism of injury (MOI), Mangled Extremity Severity Score (MESS) score and length of ischemic time. We hypothesized that ischemic time as close to six hours results in improved outcomes. METHODS Retrospective 132-month study. All popliteal artery injuries. Urban Level I Trauma Center. OUTCOME MEASURES MOI, ISS, MESS, ischemic time, risk factors for amputation, role of popliteal venous injuries, and limb salvage. STATISTICAL ANALYSIS univariate and multivariate. RESULTS 76 patients - 59 (76.1%) males and 17 (22.4%) females. MOI: penetrating - 54 (71%). MESS for penetrating injuries - 5.8 ± 1.5, blunt injuries - 5.6 ± 1.8. Admission-perfusion restoration (n = 76) - 5.97 hours (358 minutes). Ischemic time was not predictive of outcome (p = 0.79). Ischemic time penetrating (n = 58) 5.9 hours (354 ± 209 minutes), blunt 6.1 hours (371 ± 201 minutes). Popliteal arterial repairs: RSVG 44 (58%), primary repair 21 (26%), PTFE 3 (4%), vein patch 2 (2%), ligation 2 (3%), exsanguinated 4 (6%). No patients underwent stenting. Popliteal Vein: Repair 19 (65%), ligation 10 (35%). Fasciotomies 45 patients (59%). OUTCOMES Limb salvage - 90% (68/76). Adjusted limb salvage excluding intraoperative deaths - 94% (68/72). Selected patient characteristics; MOI: penetrating vs. blunt - age (p <0.0005). Amputated vs. non-amputated patients, age (p < 0.05). ISS (p < 0.005) predicted amputation, MESS (p = 0.98) did not. Mean ischemic time (p = 0.79) did not predict amputation. Relative risk of amputation, MOI - blunt (p = 0.26, RR 4.67, 95% CI: 1.11 - 14.1), popliteal artery ligation (p = 0.06, RR 3.965, 95% CI: 1.11 - 14.1) as predictors of outcome. Combined artery and vein injuries (p = 0.25) did not predict amputation. CONCLUSIONS Decreasing ischemic time from arrival to restoration of perfusion may lead to improved outcomes and increased limb salvage. MESS is not predictive for amputation. Blunt MOI is a risk factor for amputation. Maintaining ischemic times as close to six hours as possible may lead to improved outcomes.

Abstract
BACKGROUND Popliteal artery injuries are the second most common arterial injuries below the inguinal ligament. We aimed to compare outcomes in patients with popliteal injuries by hospital teaching status utilizing the National Trauma Data Bank Research Data Set (NTDB-RDS) 2013-2016. METHODS Four-year retrospective study using the NTDB-RDS, evaluating popliteal vascular injuries. Patients were divided by popliteal injury type and teaching status into; nonteaching hospital (NTH), community teaching (CTH), or University teaching (UTH). Demographics and outcome measures were compared between groups. Risk-adjusted mortality odds ratios (ORs) were calculated. Significance was defined as P < 0.05. RESULTS 3,577,168 patients were in the NTDB-RDS, with 1120 having a popliteal injury, (incidence = 0.03%). There was no significant difference in the amputation rate between patients treated in NTHs, CTHs, or UTHs (P > 0.05). There was no significant difference in the raw mortality rate between patients treated in NTHs, CTHs, or UTHs. After adjusting for confounders; compared to NTH, the odds ratio for mortality for popliteal artery injuries in the CTH group was significantly higher (OR: 15.95, 95% CI: 1.19-213.84), and for the UTH group the mortality was also significantly higher (OR: 5.74, 95% CI: 0.45-72.95). CONCLUSIONS The incidence of popliteal vascular injuries was 0.03% for 2013-2016. Patients with popliteal artery injuries treated at community teaching hospitals have a 16 times higher risk of mortality and at university teaching hospitals have a 5.7 times higher risk of mortality than patients treated at nonteaching hospitals.

Abstract
PURPOSE Knee dislocations (KDs) are potentially devastating injuries, leading to loss of function or limb in often young patients. This retrospective database review aims to determine the relative incidence and risk factors for KDs presenting to North American Level I and II trauma centers. METHODS The National Trauma Data Bank (NTDB) was retrospectively interrogated using ICD-9-CM codes to identify KDs between 2010 and 2014 to derive KD incidence. KDs were stratified by age, sex, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), drug and alcohol use, injury mechanism, open vs. closed KD, vascular injury and fracture. Each co-variate was tested against different mechanisms of injury, using Chi-squared tests and risk adjusted analyses to derive risk factors for KD. The same calculations were done for secondary outcomes (vascular and neurological injuries, compartment syndrome, amputation, and mortality). RESULTS A total of 6454 KDs met the inclusion criteria (18/10,000 admissions). KDs occurred most commonly amongst men, aged 20-39, with an ISS score 1-14 and following motor vehicle collision (MVC). A vascular investigation was performed in 29%, with injury documented in 15% of KDs and 10.8% receiving a vascular procedure. Associated fractures were observed in 41.4% of KDs. Open injuries in 13.6%. Neurological injury documented in 6.2%, compartment syndrome in 2.7%, amputation in 3.8% (> 50% had vascular injury) and 2.8% died. MVC was the most common mechanism of injury (p < 0.001), significantly more common in young, male patients, associated with higher ISS and lower GCS, especially when drugs or alcohol were involved (p < 0.0001). Being male, having a vascular injury or open KD were all risk factors for compartment syndrome, amputation and neurological injuries. CONCLUSIONS KDs are rare injuries, but their relative incidence may be increasing. Young, male patients involved in MVCs are risk factors for KDs and their associated injuries, such as neurological injuries, amputations and compartment syndrome. Vascular injury occurs at a frequency of around 15%. The findings of the current study may guide future research and help to inform clinicians on the expected rates of associated injuries in patients identified to have KD in a trauma center population. It informs regarding risk factors for KD, which may improve diagnosis rates of spontaneously reduced knee dislocations by increasing index of suspicion in high-risk patients and identifies specific links with impaired driving.

[PMID: 31978483 DOI: 10.1016/j.avsg.2020.01.079] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Revised: 12/26/2019] [Accepted: 01/12/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Popliteal artery injury (PAI) is a rare occurrence in pediatric patients with significant consequences. Delays in diagnosis lead to severe complications such as lifelong disability and limb loss. We sought to identify outcomes and clinical predictors of PAI in the pediatric trauma population. METHODS The Pediatric Trauma Quality Improvement Program (2014-2016) was queried for patients ≤17 years old with PAI. Patient demographics and outcomes were characterized. A comparison of patients sustaining blunt versus penetrating PAI was performed. A multivariable logistic regression analysis was used to identify predictors of PAI. RESULTS From 119,132 patients, 58 (<0.1%) sustained a PAI with 74.1% from blunt trauma. Most of the patients were male (75.9%) with a median age of 15 and median Injury Severity Score of 9. A majority of the patients were treated with open repair (62.1%) in comparison to endovascular repair (10.3%) and nonoperative management (36.2%). The rates of open and endovascular repair and nonoperative management were similar between blunt and penetrating PAI patients (P = not significant). Concomitant injuries included popliteal vein injury (PVI) (12.1%), posterior tibial nerve injury (3.4%), peroneal nerve injury (3.4%), and closed fracture/dislocation of the femur (22.4%), patella (25.9%), and tibia/fibula (29.3%). Overall complications included compartment syndrome (8.6%), below-knee amputation (6.9%), and above-knee amputation (3.4%). The overall mortality was 3.4%. Patients with PAI secondary to penetrating trauma had a higher rate of concomitant PVI (26.7% vs. 7%, P = 0.04) and posterior tibial nerve injury (13.3% vs. 0%, P = 0.02) but a lower rate of closed fracture/dislocation of the patella (0% vs. 34.9%, P = 0.008) and tibia/fibula (0% vs. 39.5%, P = 0.004) compared to patients with PAI from blunt trauma. Predictors for PAI included PVI (odds ratio [OR] 296.57, confidence interval [CI] = 59.21-1,485.47, P < 0.001), closed patella fracture/dislocation (OR 50.0, CI = 24.22-103.23, P < 0.001), open femur fracture/dislocation (OR 9.05, CI = 3.56-22.99, P < 0.001), closed tibia/fibula fracture/dislocation (OR 7.44, CI = 3.81-14.55, P < 0.001), and open tibia/fibula fracture/dislocation (OR 4.57, CI = 1.80-11.59, P < 0.001). PVI had the highest association with PAI in penetrating trauma (OR 84.62, CI = 13.22-541.70, P < 0.001) while closed patella fracture/dislocation had the highest association in blunt trauma (OR 52.01, CI = 24.50-110.31, P < 0.001). CONCLUSIONS A higher index of suspicion should be present for PAI in pediatric trauma patients presenting with a closed patella fracture/dislocation after blunt trauma. PVI is most strongly associated with PAI in penetrating trauma. Prompt recognition of PAI is crucial as there is a greater than 10% amputation rate in the pediatric population.

Abstract
BACKGROUND Arterial injury secondary to acute knee dislocation (KD) is a rare but devastative complication. The aim of this study is to evaluate functional sequelae and factors of poor prognosis. METHODS A retrospective monocentric series of consecutive KD with acute ischemia by popliteal artery injury was analyzed between 2005 and 2017. The main outcome was the amputation rate. RESULTS Sixteen dislocations were included. Nine (56%) were due to public road accidents, 5 (31%) were due to falls from height, and 2 (13%) were due to sports injuries. Dislocation had occurred in the posterior location in 8 (50%) cases. Regarding arterial injury, there were 7 (44%) ruptures, 7 (44%) dissections, and 2 (13%) isolated thromboses. Eleven (69%) KDs with vascular trauma were associated with signs of acute ischemia. Revascularization was achieved by anatomical venous bypass in 14 (88%), resection and direct anastomosis in one (6%), and isolated thrombectomy in one (6%). Median time to surgery (time between trauma and vascular repair) was 7 hours (3.25-60.92 hours). Primary revascularization was performed in 12 (75%) cases. In three cases (19%), orthopedic reduction and stabilization were performed first. In one case, (6%) three-step management with vascular shunt at first, then with knee stabilization, and finally vascular bypass was carried out. Stabilization was achieved by using an external fixator in 13 (82%) cases, by open reduction and internal fixation in one case (6%), by ligamentoplasty in one (6%), and by using a long leg cast in one (6%). Fasciotomy was required in 12 (75%) cases. Two patients had early vascular complications, and 2 had early systemic complications. Three secondary transfemoral amputations were performed. Median follow-up duration was 23 months. No secondary amputation was recorded. At the end of follow-up, functional outcomes were evaluated using the Oxford Knee Score (OKS). The median OKS was 30 versus the pretrauma median OKS of 47 (P < 0.00028). No risk factor associated with limb amputation has been highlighted. CONCLUSIONS Analysis of these results provided indications for therapeutic management of this condition. This study shows poor functional outcomes because of severity of vascular lesion in patients with orthopedic trauma but with healthy arteries.

Abstract
Popliteal artery trauma is uncommon but is associated with a high risk of limb loss depending on the scenario involving blunt or penetrating trauma as well as the severity and extent of injury that has occurred. In our setting there is a significant amount of gang and civilian warfare resulting in Vascular Trauma. There were 32 patients over a decade who sustained traumatic injury to the popliteal artery consisting of 30 males (94%) and 2 females with an age range 16-59 years with a mean of 32. There were 20 cases of penetrating trauma (63%) and 12 cases of blunt trauma (37%). Of the penetrating trauma, 18 were due to gunshot wounds (GSWs) (90%) and 2 stabs. The majority (7/12; 58%) of blunt trauma was due to falls, and 42% (5/12) secondary to motor vehicular accidents (MVAs). In terms of extent of injury, 21 of 32 patients (65%) sustained an isolated popliteal artery injury, whilst 6 (19%) had injury to both the popliteal artery and vein and another 5 (16%) had combined popliteal artery, vein and nerve injuries. There were 14 cases with associated orthopaedic injuries: 7 posterior knee dislocations, 1 fracture/dislocation of the knee, 2 femoral fractures, 2 tibial plateau fractures and 2 tibia/fibula fracture. Methods of repair included 14 reversed vein grafts, 16 polytetrafluoroethylene (PTFE) grafts and 2 primary. The overall amputation rate was 28% (9 patients). Of the penetrating trauma patients 25% required amputations composed of 5 GSWs, 33% of the blunt trauma patients required amputations. It was noted that factors associated with (but not statistically significant) poor outcomes included combined artery/vein injury, artery/vein/nerve injury, concomitant fracture/dislocation and delayed transfer to a Vascular Surgery Unit. The type of graft or repair did not affect outcome. The incidence of popliteal artery trauma was calculated at 2.46 per 100,000 population per year.

Abstract
Popliteal artery injuries may have devastating consequences if not recognized in a timely fashion. The risk of delayed diagnosis of a vascular injury is particularly high in blunt trauma to the lower extremity. We present a case of popliteal artery injury that is unusual in two respects: severity (a complete transection in the setting of a blunt injury) and lack of clinical and radiographic signs of the commonly associated musculoskeletal injuries.

Abstract
Abstract
Background
Lower extremity vascular trauma (LEVT) is a major cause of amputation. A clear understanding of prognostic factors for amputation is important to inform surgical decision-making, patient counselling and risk stratification. The aim was to develop an understanding of prognostic factors for amputation following surgical repair of LEVT.
Methods
A systematic review was conducted to identify potential prognostic factors. Bayesian meta-analysis was used to calculate an absolute (pooled proportion) and relative (pooled odds ratio, OR) measure of the amputation risk for each factor.
Results
Forty-five studies, totalling 3187 discrete LEVT repairs, were included. The overall amputation rate was 10·0 (95 per cent credible interval 7·4 to 13·1) per cent. Significant prognostic factors for secondary amputation included: associated major soft tissue injury (26 versus 8 per cent for no soft tissue injury; OR 5·80), compartment syndrome (28 versus 6 per cent; OR 5·11), multiple arterial injuries (18 versus 9 per cent; OR 4·85), duration of ischaemia exceeding 6 h (24 versus 5 per cent; OR 4·40), associated fracture (14 versus 2 per cent; OR 4·30), mechanism of injury (blast 19 per cent, blunt 16 per cent, penetrating 5 per cent), anatomical site of injury (iliac 18 per cent, popliteal 14 per cent, tibial 10 per cent, femoral 4 per cent), age over 55 years (16 versus 9 per cent; OR 3·03) and sex (men 7 per cent versus women 8 per cent; OR 0·64). Shock and nerve or venous injuries were not significant prognostic factors for secondary amputation.
Conclusion
A significant proportion of patients who undergo lower extremity vascular trauma repair will require secondary amputation. This meta-analysis describes significant prognostic factors needed to inform surgical judgement, risk assessment and patient counselling.

Abstract
BACKGROUND Vascular injury is a devastating complication of acute knee dislocation. However, there are wide discrepancies in the reported frequency of vascular injury after knee dislocations, as well as important differences among approaches for diagnosis of this potentially limb-threatening problem. QUESTIONS/PURPOSES We determined (1) the frequency of vascular and neurologic injury after knee dislocation and whether it varied by the type of knee dislocation, (2) the frequency with which surgical intervention was performed for vascular injury in this setting, and (3) the frequency with which each imaging modality was used to detect vascular injury. METHODS We searched the MEDLINE(®) literature database for studies in English that examined the clinical sequelae and diagnostic evaluation after knee dislocation. Vascular and nerve injury incidence after knee dislocation, surgical repair rate within vascular injury, and amputation rate after vascular injury were used to perform a meta-analysis. Other measures such as diagnostic modality used and the vessel injured after knee dislocation were also evaluated. RESULTS We identified 862 patients with knee dislocations, of whom 171 sustained vascular injury, yielding a weighted frequency of 18%. The frequency of nerve injuries after knee dislocation was 25% (75 of 272). We found that 80% (134 of 160) of vascular injuries underwent repair, and 12% (22 of 134) of vascular injuries resulted in amputation. The Schenck and Kennedy knee dislocation classifications with the highest vascular injury prevalence were observed in knees that involved the ACL, PCL, and medial collateral liagment (KDIIIL) (32%) and posterior dislocation (25%), respectively. Selective angiography was the most frequently used diagnostic modality (61%, 14 of 23), followed by nonselective angiography and duplex ultrasonography (22%, five of 23), ankle-brachial index (17%, four of 23), and MR angiography (9%, two of 23). CONCLUSIONS This review enhances our understanding of the frequency of vascular injury and repair, amputation, and nerve injuries after knee dislocation. It also illustrates the lack of consensus among practitioners regarding the diagnostic and treatment algorithm for vascular injury. After pooling existing data on this topic, no outcomes-driven conclusions could be drawn regarding the ideal diagnostic modality or indications for surgical repair. In light of these findings and the morbidity associated with a missed diagnosis, clinicians should err on the side of caution in ruling out arterial injury.

Abstract
OBJECTIVE Clinical obesity is an epidemic problem in the United States. The impact of this disease upon traumatic lower extremity vascular injuries (LEVI) is as yet undefined. We hypothesized that clinical obesity adversely affects outcome in patients with traumatic LEVI. METHODS All adult patients admitted over a 5-year period with a traumatic LEVI were identified. Clinical obesity was defined as body mass index (BMI)>30. Obese and non-obese patient groups were compared for surgical management and outcome. RESULTS A total of 145 patients were identified. BMI data were available for 115 (79.3%) of these patients (obese n=47; non-obese n=68). Obese and non-obese groups were similar. Obese patients underwent more vascular repairs but the amputation rate and mortality were not significantly different. CONCLUSIONS While obese body habitus can increase the complexity of evaluation and management of patients with LEVI, we have demonstrated that equivalent outcomes to the non-obese population can be achieved for the clinically obese patient with a BMI>30. However, patients with a BMI>40 did reveal a significantly higher chance of amputation and death after LEVI. Due to the small number of patients in this subset, one should use caution when interpreting this data.

Abstract
INTRODUCTION Knee dislocation is an unusual condition, and can have catastrophic consequences, such as vascular and neurological complications, in addition to the ligament injuries. OBJECTIVE The aim of this study is to analyse the effectiveness of a protocol of early diagnosis of vascular injuries associated with knee dislocations. MATERIALS AND METHODS A retrospective study was conducted which included acute knee dislocations treated in our institution, with a minimum of 12 months follow-up, between 1999-2010. A diagnostic protocol based on physical examination and ankle-brachial index was used in order to detect vascular injuries. RESULTS Ten dislocations, 30% with popliteal artery injury, were diagnosed early and received emergency treatment within 8 hours. There were associated neurological injuries in two patients. There were no amputations. CONCLUSIONS The systematic use of this protocol has avoided consequences of late diagnosis and has drastically reduced the abusive use of invasive tests, such as arteriography.

Abstract
Extended length of time from injury to definitive vascular repair is considered to be a predictor of amputation in patients with popliteal artery injuries. In an urban trauma center with a rural catchment area, logistical issues frequently result in treatment delays, which may affect limb salvage after vascular trauma. We examined how known risk factors for amputation after popliteal trauma are affected in a more rural environment, where patients often experience delays in definitive surgical treatment. All adult patients admitted to the Level I trauma center, the University of Mississippi Medical Center, with a popliteal artery injury between January 2000 and December of 2007 were identified. Demographic information management and outcome data were collected. Body mass index, mangled extremity severity score (MESS), Guistilo open fracture score, injury severity score, and time from injury to vascular repair were examined. Fifty-one patients with popliteal artery injuries (53% blunt and 47% penetrating) were identified, all undergoing operative repair. There were nine amputations (17.6%) and one death. Patients requiring amputation had a higher MESS, 7.8 versus 5.3 ( P < 0.01), and length of stay, 43 versus 15 days ( P < 0.01), compared with those with successful limb salvage. Body mass index, injury severity score, Guistilo open fracture score, or time from injury to repair were not different between the two groups. Patients with a blunt mechanism of injury had a slightly higher amputation rate compared with those with penetrating trauma, 25.9 per cent versus 8.3 per cent ( P = non significant). MESS, though not perfect, is the best predictor of amputation in patients with popliteal artery injuries. Morbid obesity is not a significant predictor for amputation in patients with popliteal artery injuries. Time from injury to repair of greater than 6 hours was not predictive of amputation. This study further demonstrates that a single scoring system should be used with caution when determining the need for lower extremity amputation.

Abstract
Purpose: The purpose of this study is to report the clinical and functional outcomes of patients, treated between 2004 and 2009, with high-risk popliteal vascular injuries due to compound fractures about the knee. Patients and methods: A retrospective analysis was conducted of prospectively collected data from Tabriz Medical Trauma Center. Our aim was to perform surgical revascularization as soon as the arterial injury was recognized. The mechanism of injury was blunt in the entire cohort of patients, and all of them had bone fractures about the knee. The treatment of arterial injury included vein graft interposition in 39 (63%), primary anastomosis in 20 (32.3%), and lateral repair in 3 (4.8%) patients. The patients were divided into 2 study groups: limb salvage group (group 1) and amputation group (group 2). Subgroup analysis consisted of univariate analysis comparing the 2 groups and multivariate analysis examining the factors associated negatively and positively with the primary endpoint, limb salvage. Results: In the entire cohort of patients, 60 patients (97%) were male and 2 were female (3%); the mean age was 34.1 years (16–49 years). The overall amputation rate in this study was 37.1% (23 amputations). Significant (P < 0.05) independent factors associated negatively with limb salvage were combined tibia and fibula fracture, concomitant artery and vein injury, ligation of venous injury, and lack of backflow after Fogarty catheter thrombectomy, while repair of popliteal artery and vein injury, when present, was associated with improved early limb salvage. For 40 patients, we adopt a liberal attitude toward open 4-compartment fasciotomy through both medially and laterally placed incisions. Conclusion: Expeditious recognition of vascular injury, transport to repair, and repair of associated venous injury when possible are necessary to optimize limb salvage. The importance of a high level of suspicion and low threshold for timely amputation has been emphasized when limb salvage was deemed impossible to prevent life-threatening complication. Delays in surgery, extensive soft tissue defect, compound tibia–fibula fracture, and other factors are associated with high amputation rate following popliteal artery injury.

Abstract
Knee dislocation is a complex and rare injury often presenting in the context of high velocity trauma. The aim of this study is to establish the subjective outcomes of surgically treated knee dislocations. A total of 20 knees dislocations treated by open repair were reviewed. Their progress and outcomes were assessed by using a modified Lysholm score questionnaire. Data was obtained on patient demographics, details of injury, investigation, treatment, rehabilitation, 24 months objective outcome and subjective outcomes. Six patients had a vascular deficit and six had neurological deficits. The median range of motion was 0°-100°. Patients with an initially lower pre-injury level of function were able to return an activity level comparable to their pre-injury status. 22% of competitive athletes retuned to competitive sports. 38% of patients undertaking heavy activity returned to comparable pre-injury level of activity and 67% of patients undertaking moderate level of activity before injury returned to a comparable level after repair. 68% regularly had problems running, 70% problem squatting, 40% swelling and 42% problem with stairs. Most patients however did not have locking of the knee or problems with knees giving way. Patients pain scores decreased over time to an acceptable level. Despite the severity of the injury, majority of patients achieved a satisfactory outcome, although none of the patients reached the same level of function as before the injury. 80% of the patients were satisfied with their outcome. All dissatisfied patients suffered postoperative complications.

Abstract
INTRODUCTION Knee dislocation and bicruciate lesions are rare. Assessments of results from retrospective series carry an insufficient level of evidence. A prospective multicenter study was therefore set up, under the auspices of the French Society of Orthopedic Surgery. MATERIAL AND METHODS The inclusion period covered the whole of 2007. Clinical, imaging (dynamic X-ray and MRI) and vascular (angioscan and arteriography) assessment was performed systematically. In patients over the age of 60 years, ligament lesions were always managed non-surgically; in those under the age of 60 years, surgery was considered in the absence of associated vascular lesion or open dislocation and if there was frontal laxity exceeding 15 degrees or a posterior drawer test greater than 10mm. The posterior cruciate ligament (PCL) and peripheral ligament tears were repaired or reinforced under arthroscopy or by arthrotomy. The anterior cruciate ligament was never operated on. In all other cases, management was conservative. RESULTS Sixty-seven knees were included (55 male, 11 female; mean age: 37 years). Fifteen patients (25.4%) had bicruciate lesion, and 44 (74.6%) knee dislocation. Mean trauma-to-reduction interval was 3 hrs 50 min. Only one of the nine cases of popliteal artery lesion exhibited discernible distal pulse wave. Only three of these patients underwent vascular surgical repair. Twelve knees (five bicruciate lesions, seven dislocations) had isolated common peroneal nerve damage. DISCUSSION This prospective study detailed the epidemiology and treatment of the lesions encountered, with the option of PCL and peripheral ligament reconstruction. The results, however, still require long-term analysis.

Abstract
BACKGROUND The management of combined arterial and musculoskeletal injuries to the lower extremity remains controversial, particularly with regard to the initial order of intervention and the use of intravascular shunting. In this study, we review the contemporary management and outcome of patients treated for acute traumatic distal femoropopliteal arterial injuries. METHODS From January 2001 to January 2006, we repaired 57 acute traumatic lower-extremity arterial injuries in a level 1 trauma center. Our approach was to perform surgical revascularization without intraluminal shunting as soon as the arterial injury was recognized. There were 44 men (77%). Mean age was 31 years (range, 5-68). The mechanism of injury was blunt in 42 of 57 (74%) patients. Vascular reconstruction was achieved by using an autogenous saphenous vein graft in 52 of 57 (91%), a vein patch in 3 of 57 (5%), or primarily in 2 of 57 (4%) patients. RESULTS The limb-salvage rate was 92% (53/57). Thirty-six patients (63%) had associated orthopedic fixation: 12 of 36 (33%) before and 24 of 36 (67%) after revascularization. Twenty-one of 57 patients (37%) had vascular repair only without orthopedic fixation. Thirty-four patients (60%) required fasciotomy. Four patients had subsequent above-knee amputation: 3 because of wound complications despite successful revascularization and 1 because of failed revascularization. There were no complications related to the arterial repairs that were performed before orthopedic fixation. CONCLUSION Our study shows that arterial reconstruction for acute traumatic lower-limb injuries results in a good limb-salvage rate. We advocate prompt vascular repair before orthopedic intervention for combined vascular and skeletal injuries of the lower extremity, without using intravascular shunting.
