Randall ZD, Strok MJ, Mazzola JW, Agrawal R, Yaeger LH, Berkes MB. The known and unknown reality of knee dislocations: A systematic review. Injury 2024; 55:111904. [PMID: 39357194 DOI: 10.1016/j.injury.2024.111904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 08/27/2024] [Accepted: 09/15/2024] [Indexed: 10/04/2024]
Abstract
BACKGROUND Knee dislocations (KD) are limb threatening injuries known to cause significant dysfunction and disability. This review aims to summarize KD knowledge and uncover areas where more research is needed. METHODS The published literature was queried according to PRISMA guidelines. Studies eligible for inclusion were clinical studies of knee dislocations. Studies published before 1990, or that focused on patellofemoral dislocation were excluded. RESULTS A total of 132 studies involving 43,869 knee dislocations were analyzed. The majority of patients were young adult males, with high-velocity trauma, particularly motor vehicle accidents, being the most common cause. Substance use and alcohol involvement were commonly reported. The predominant KD types were KD III (54.8 %) and KD IV (20.5 %). Meniscal tears were observed in over 50 % of cases, while cartilage injuries were present in 26.7 %. Neurovascular complications were significant, with popliteal artery injuries in 7.8 % and peroneal nerve injuries in 15.3 % of patients. Acute ligament repairs (64.2 %) were more common than delayed repairs (35.8 %), although the average time to repair was 56.1 days. Complications included amputations (2.3 %), fatalities (1.9 %), compartment syndrome (2.7 %), deep infection (5.3 %), and heterotopic ossification (21.6 %). Despite these severe injuries, a substantial loss to follow-up (19 %) and underreporting of functional outcomes were noted, limiting the comprehensive assessment of long-term recovery. A notable percentage of patients did not return to work or sports, with many requiring a change in profession due to their injuries, but these outcomes were only reported in 10 or fewer studies. CONCLUSION This study highlights the significant gaps in understanding the treatment strategies, financial burden, and long-term outcomes of knee dislocations. The incomplete data, particularly the high loss to follow-up rates and underreported functional outcomes, hinders the ability to make comprehensive assessments. Available results should thusly be interpreted with an understanding of the gaps in data, however return to sport and prior employment is often not achieved. Additionally, the potential influence of socioeconomic factors and substance abuse on treatment decisions and outcomes remains inadequately explored. Future research should focus on these areas to improve the management and prognosis of patients with knee dislocations, ensuring more accurate and thorough evaluations of long-term recovery and quality of life.

Outcomes of Surgical Treatment for Multiligament Knee Injuries in a Cohort Including Competitive Athletes With Long-Term Follow-Up. Orthop J Sports Med 2024; 12:23259671241266619. [PMID: 39247533 PMCID: PMC11375643 DOI: 10.1177/23259671241266619] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Accepted: 02/13/2024] [Indexed: 09/10/2024] Open
Abstract
Background There is a paucity of outcomes data on surgical reconstruction for multiligament knee injury (MLKI) in the orthopaedic literature. Purpose To examine functional and return-to-sports (RTS) outcomes and revision rates after single-stage reconstruction for MLKIs in a cohort containing a large proportion of competitive athletes over a 20-year period. Study Design Case series; Level of evidence, 4. Methods We identified all patients at our institution who underwent surgical reconstruction for an anterior cruciate ligament (ACL) or bicruciate (ACL-posterior cruciate ligament) MLKI between 2001 and 2020 and had ≥2 years of postoperative outcome data. Patient-reported outcomes were evaluated using the International Knee Documentation Committee (IKDC) form, a surgical satisfaction survey, and questions about subsequent knee surgery and RTS administered via telephone. Summary statistics for all outcomes data were calculated, and predictors of IKDC scores at follow-up were examined using univariable linear regression. Results Out of 151 patients eligible for this study, outcomes data were collected in 119 patients (79%). The mean follow-up time was 8.3 ± 4.4 years, and the mean IKDC score at follow-up was 79 ± 17. A total of 83 competitive athletes were included; 62 of these athletes attempted to return to preinjury sport. Among the 62 who attempted RTS, 50 (81%) were successful, and 12 were unable to return due to limitations from their surgery. At follow-up, 112 of the overall cohort of 119 patients (94%) were either satisfied or very satisfied with their surgical outcome, and 91% stated the surgery met or exceeded their expectations. In addition, 24% had subsequent ipsilateral knee operations after their index multiligament knee reconstruction. Older age at surgery and female sex were associated with worse IKDC scores at follow-up. Conclusion Despite the severity of the injuries in our cohort, we found high levels of patient-reported function and a high rate of successful RTS in the competitive athletes. Older age and female sex were associated with worse patient-reported knee function at follow-up.

High Levels of Satisfaction and Adequate Patient-Reported Outcomes After Operative Reconstruction of Multiligament Knee Injury With Allograft Among Patients Aged 40 Years and Older. Arthrosc Sports Med Rehabil 2022; 5:e29-e34. [PMID: 36866310 PMCID: PMC9971898 DOI: 10.1016/j.asmr.2022.09.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 09/26/2022] [Indexed: 12/23/2022] Open
Abstract
Purpose To describe injury characteristics and patient-reported outcomes (PROs) among patients aged 40 years and older who underwent allograft reconstruction for multiligament knee injury (MLKI). Methods Records of patients aged 40 years and older who underwent allograft multiligament knee reconstruction at a single institution between 2007 and 2017 with a minimum of 2 years of follow-up were retrospectively reviewed. Demographic information, concomitant injuries, patient satisfaction, and PROs including International Knee Documentation Committee and Marx activity scores were obtained. Results Twelve patients were included with a minimum follow-up time of 2.3 years (mean, 6.1; range, 2.3-10.1 years) and a mean age at surgery of 49.8 years. Seven patients were male, and the most common mechanism of injury was sport-related. The most frequently reconstructed MLKIs were anterior cruciate ligament and medial collateral ligament (4), anterior cruciate ligament and posterolateral corner (2), and posterior cruciate ligament and posterolateral corner (2). The majority of patients reported satisfaction with their treatment (11). Median International Knee Documentation Committee and Marx scores were 73 (interquartile range, 45.5-88.0) and 3 (interquartile range 0-5), respectively. Conclusions Patients aged 40 years and older can expect a high level of satisfaction and adequate PROs at 2-years follow-up after operative reconstruction for a MLKI with allograft. This demonstrates that allograft reconstruction for a MLKI in older patients may have clinical utility. Level of Evidence IV, therapeutic case series.

Abstract
PURPOSE Schenck IV knee dislocation patients have dissatisfactory knee function and return-to-sport rate with the existing treatment methods. The purpose of this study was to illustrate a one-stage arthroscopic multiple ligament reconstruction method for treating Schenck IV knee dislocations. METHODS A retrospective case series study was performed. All patients with a history of Schenck IV knee dislocation who underwent one-stage arthroscopic multi-ligament reconstruction from 2010 to 2018 were followed for 24 months. The outcomes, including general patient data, Lysholm scores, International Knee Documentation Committee (IKDC) scores, visual analog scale (VAS) pain scores, knee active range of motion, and complications, were reviewed. The data was analyzed with paired-samples t-test. RESULTS A total of 12 patients, comprising nine males and three females, were followed up and reviewed. The mean age at the time of the surgical procedure was 40.3 ± 9.0 (22-57) years. The mean body mass index (BMI) was 24.6 ± 4.9 (15.2-32.5) kg/m2 . The mean IKDC score and Lysholm score before surgery were 30.4 ± 6.1 (21-42) and 28.2 ± 6.2 (22-39), respectively. The average operation time was 121.8 minutes. The mean IKDC score and Lysholm score at the 24-month follow-up were 80.6 ± 6.5 (68-92) and 82.0 ± 7.5 (72-95), respectively. There were significant differences in the IKDC and Lysholm scores between the preoperative and 24-month postoperative time points (p < 0.01). The mean knee range of motion was 124.6° ± 6.6° (115°-135°) at the 24-month follow-up. No major complications occurred. CONCLUSIONS The results of this retrospective study suggest that the new arthroscopic one-stage multi-ligament reconstruction technique is an effective way to treat Schenck IV knee dislocation with satisfactory postoperative knee function.

Abstract
BACKGROUND Multiligament knee injuries (MLKIs) can result from high-energy injury mechanisms such as motor vehicle accidents or low-energy injury mechanisms such as activities of daily living or sports. PURPOSE/HYPOTHESIS The purpose was to conduct a systematic review on postoperative patient-reported outcomes after MLKIs and to conduct a meta-analysis of comparable outcome variables based upon high- versus low-energy injury mechanisms. It was hypothesized that MLKIs with low-energy injury mechanisms would demonstrate significantly improved subjective clinical outcome scores compared with high-energy injuries. STUDY DESIGN Meta-analysis and systematic review. METHODS A systematic review was performed with the inclusion criteria of postoperative MLKI outcomes based upon high-versus low-energy mechanisms of injury with a minimum 2-year follow-up. Outcome scores included were the Lysholm knee scoring scale, Tegner activity scale, and the International Knee Documentation Committee (IKDC) score. High-energy mechanisms included motor vehicle accidents or falls from a height >5 feet; low-energy mechanisms included sports-related injuries, activities of daily living, or falls from <5 feet. A meta-analysis was performed comparing the outcome scores of high- versus low-energy mechanisms of MLKIs. RESULTS Overall, 1214 studies were identified, 15 of which were included in the systematic review and meta-analysis. Thirteen studies included surgical reconstructions of all injured ligaments. A total of 641 patients with 275 high-energy and 366 low-energy injuries were grouped for comparison in the meta-analysis. No significant differences in Lysholm scale (78.6 vs 78.0) or IKDC scores (69.0 vs 68.4) were found between high- and low-energy groups at a minimum of 2 years (range, 2-10 years) postoperatively (P > .05). The low-energy injury group demonstrated significantly higher Tegner activity scale scores (5.0 vs 3.9; P = .03). There was no significant difference in failure rates between groups (3.5% vs 2.0%; P = .23). CONCLUSION We found in this systematic review and meta-analysis that patients with low-energy mechanisms of MLKI surgery had improved postoperative Tegner activity scores compared with those patients with high-energy mechanisms after MLKI surgery. However, there were no differences in Lysholm score, IKDC score, or failure rates between high- and low-energy MLKI patients at an average of 5.3 years postoperatively.

Abstract
Background: The incidence of concomitant injuries, including meniscal and cartilage injuries, has not been adequately reported in previous studies on multiligament knee injury (MLKI) because their primary focal points have been the degree of ligament injury, treatment strategy, involvement of other soft tissues, and neurovascular injury. Purpose: To analyze the incidence of associated lesions in MLKIs, including medial and lateral meniscal injuries, cartilage lesions, and complications. Study Design: Systemic review; Level of evidence, 4. Methods: The PubMed, Embase, Cochrane Library, CINAHL, and Scopus databases were searched between inception and April 30, 2020. Studies were included if they reported the incidence rates of medial and/or lateral meniscal tears and cartilage injuries in cases of MLKIs. For the meta-analysis, data were extracted on clinical outcomes measured according to the number of medial and/or lateral meniscal tears, cartilage injuries, and complications. Results: A total of 45 studies were included in the MLKI analysis (3391 patients). The pooled rate of medial meniscal tears was 30.4% (95% CI, 24.1%-37.1%; P < .0001; I2 = 85.8%). The pooled rate of lateral meniscal tears was 27.5% (95% CI, 20.3%-35.3%; P < .0001; I2 = 89.6%). The pooled rate of cartilage injuries was 27.5% (95% CI, 22.1%-33.3%; P < .0001; I2 = 86.8%). The pooled rates of peroneal nerve injuries, vascular injuries, and arthrofibrosis were 19.2% (95% CI, 14.2%-24.7%; P < .001; I2 = 81.3%), 18.4% (95% CI, 13.2%-24.3%; P < .0001; I2 = 81.0%), and 11.2% (95% CI, 8.1%-14.7%; P = .0018; I2 = 54.0%), respectively. Conclusion: The pooled rates of meniscal tears and cartilage injuries concomitant with MLKIs were high, ranging from 27% to 30%, and the pooled rates of peroneal nerve injury, vascular injury, and arthrofibrosis were considerable, ranging from 11% to 19%. The influence of these associated lesions on clinical results should be evaluated in future clinical studies.

Abstract
INTRODUCTION Multi-ligamentous knee injuries (MLKI) are rare orthopedic injuries with diverse approaches to its management protocol. The purpose of this study was to determine the epidemiology of MLKI in our centre and its outcome in single stage reconstruction. METHODS 60 patients who were surgically treated for MLKI between 2014 and 2018 were included in this study, data was collected pre and postoperatively and their Lysholm and IKDC scores were used to evaluate the outcomes. RESULTS A male predominance was noted in the present study. Road traffic accidents (RTA) were the most common mode of injury (66.7%). ACL & MCL combination constituted the most common injury pattern (36.7%). 41.7% of our patients were treated within 3 weeks from injury and 58.3% were treated 3 weeks after injury and there was no statistically significant difference in their outcomes with a p value > 0.05 for their post op Lysholm scores and post op IKDC scores. Overall, there was a statistically significant difference in outcomes post surgery with regards to pre-operative and post-operative Lysholm and IKDC scores in our patients with a p value < 0.0001, substantiating the need for surgical management of MLKI. With a mean post-operative Lysholm score of 89.11 and mean post operative IKDC score of 85.25, this study showed functionally good results in the patients treated in a single sitting. 28 of 60 patients could get back to their sports activities after atleast 6 months of rehabilitation. CONCLUSION MLKI are relatively uncommon injuries eluding a large scale prospective clinical studies and consensus regarding its management. In the present study, a male predominance was noted, high velocity injuries like RTA was the most common mechanism of injury. A combination of ACL & MCL accounted for the most common pattern of injury. We could also conclude that surgical management yields good results irrespective of the time since injury i.e. either early (<3 weeks) or delayed (>3 weeks) surgery. Single stage surgical management of MLKI produce considerably better outcomes compared to staged management. It was also found that surgical management of MLKI with reconstruction could help patients to return to their pre operative level of sports activities with a proper rehabilitation protocol.

Abstract
PURPOSE The purpose of this study was to describe the longitudinal outcomes of acute repair and augmentation for the reconstruction of dislocated knees, using LARS synthetic ligaments. METHODS Patients with a knee dislocation surgically treated using LARS synthetic ligament augmentation, with a minimum follow-up of 24 months, were enrolled between 1996 and 2014. Range of motion, Lachman, pivot shift, posterior drawer, step off sign, valgus, varus, KT-1000 arthrometer, Telos technique, IKDC, Lysholm, Tegner, and Meyers scores were obtained every 2 years up to 10 years. RESULTS Median age was 32.1 years (IQR 23.2-43.3) at time of surgery. Median time from trauma to surgery was 9 days and mean follow-up time was 6.6 years. Median questionnaire scores were: Lysholm 79.5 (IQR 65.0-89.0), Tegner 4.0 (IQR 3.7-6.0), Meyers 3.0 (IQR 3.0-4.0), and mean IKDC was 63.8 (SD 18.9). Median flexion and extension of the injured knee was 124° (IQR 115-129.5) and 0° (IQR - 5 to 0), respectively. Median KT-1000 differential was 0.7 mm (IQR 0.1-3.1) for ACL and 0.9 mm (IQR 0.2-1.4) for PCL. Mean differential for Telos was 2.5 mm (SD 5.8) for ACL, 4 mm (IQR 2-6.3) for PCL 30°, and 8.2 mm (SD 4.4) for PCL 90° (consistent with PCL laxity). More than 90% of patients had good anterior articular stability and > 60% of patients had good posterior articular stability. CONCLUSIONS Acute repair and augmentation of knee dislocations with LARS synthetic ligaments resulted in satisfactory outcomes for the ACL and collateral structures. Telos stress radiography showed PCL laxity in more than half of cases despite low laxity results with KT-1000. The perception of patients about knee function was sustained in time.

[PMID: 29429563 DOI: 10.1016/j.arthro.2017.12.025] [Citation(s) in RCA: 53] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2017] [Revised: 11/13/2017] [Accepted: 12/04/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE To systematically review multiligament knee injury (MLKI) outcome studies to determine overall rates of return to work or sport after MLKI and risk factors for lack of return to work or sport after MLKI. METHODS A search was performed of MLKI outcome studies from 1950 to March 1, 2017. Ninety-two studies were identified. All included reported return to work, return to sport, or Tegner activity scores. Rates of return to work or sport were determined for overall population and by obesity status, injury severity, and presence of peroneal nerve or vascular injury. RESULTS A total of 524 patients (21 studies) were included. Return to high-level sport was low (22%-33%). Return to any level of sport was 53.6% overall (178/332), with a higher rate reported in studies with all surgical patients (59.1%, 114/193 patients) versus studies with mixed surgical and nonoperative treatment (46.0%, 64/139 patients) (P = .02). Rate of return to work with little or no modifications was 62.1% (146/200) and return to any work was 88.4% (190/215). Obese patients had lower postoperative Tegner scores than a general population (obese: mean 1.7 ± 1.2; nonobese: mean 4.5 ± 1.0; P < .001). Among studies without Schenck grade IV and V injuries, return to work with no or minimal modifications (100%, 12/12 patients) was higher than studies including grade IV and V patients (66.0%, 70/106 patients) (P = .017). Return to any work was higher in studies without vascular injuries (96.3%, 105/109) versus those including them (80.2%, 85/106) (P < .001). CONCLUSIONS Return to sport after MLKI occurs in approximately 60% of surgically treated patients, though return to high-level sport is lower. Return to work is frequently possible after MLKI though it may require workplace or job duty modifications. Obesity, nonoperative treatment, higher injury severity, and vascular injury are associated with poorer functional outcomes. LEVEL OF EVIDENCE Level IV, systematic review of level III and IV studies.

[PMID: 28754264 DOI: 10.1016/j.knee.2017.05.023] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2016] [Revised: 04/28/2017] [Accepted: 05/31/2017] [Indexed: 02/02/2023]
Abstract
OBJECTIVE The purpose of this study was to report the clinical and functional results of patients who underwent surgical management for posterior knee dislocation associated with extensor apparatus rupture. INTRODUCTION Posterior knee dislocations associated with extensor apparatus ruptures are defined as rare but complicated injuries, which are difficult to return to the level of activity prior to the injury. The study demonstrated a hypothesis that good knee stability and early gain of range of motion could be achieved with deliberate design of the treatment protocol and proper application of the instruments. METHODS Fifteen patients with posterior knee dislocations associated with extensor apparatus ruptures were evaluated after reduction and repair of extensor apparatus. Following that, multiple-ligament reconstruction in association with use of a lateral knee-spanning external fixator was applied for at least six weeks. Ligament reconstructions were performed using allografts. Range of motion and knee stability were both measured at each follow-up evaluation at a mean time of 36months. The assessment was made using the Lysholm Knee Scoring Scale. RESULTS The mean Lysholm scale score was 87.6 (range 73-95), with excellent in 11 cases, good in two, and fair in two. In the final evaluation, the range of motion was a mean range of 123.4° (range 100-135). CONCLUSION The use of a lateral knee-spanning external fixator ensured the safety of repaired vessels, knee stability after reduction, and early rehabilitation with range of motion.

Acute surgical management of traumatic knee dislocations--Average follow-up of 10 years. Knee 2016; 23:267-75. [PMID: 26545616 DOI: 10.1016/j.knee.2015.09.019] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2014] [Revised: 09/22/2015] [Accepted: 09/25/2015] [Indexed: 02/02/2023]
Abstract
BACKGROUND Traumatic knee dislocations have been managed historically by means of either delayed reconstruction or non-operative methods. More recently, there has been a trend towards early reconstruction. There is no clear consensus in the literature as to how such patients should be managed and in what time frame. OBJECTIVE The aim of this study was to establish the long-term outcome of patients who underwent acute surgical management of their traumatic knee dislocation. METHODS Thirty-six patients with traumatic knee dislocations were treated by multi-ligament reconstruction. All surgical interventions occurred within 21 days of presentation. The collateral ligament complexes were primarily repaired where possible and reconstructions were performed with either autograft, allograft or the ligament augmentation and reconstruction system (LARS) synthetic graft. RESULTS The mean time to surgery was 12 days (1 to 21) with a mean follow-up of 10.1 years (7 to 19). The International Knee Documentation Committee (IKDC) assessment demonstrates that 56% of patients went on to have "nearly normal" knee function and the average Tegner-Lysholm score of 80 (57 to 91), is consistent with good function. The Knee Outcome score (KOS) was 84% for Activities of Daily Living and 74% for Sports. CONCLUSION This study demonstrates a high level of overall knee function following the acute surgical reconstruction of traumatic knee dislocations.

[PMID: 25620500 DOI: 10.1016/j.arthro.2014.11.032] [Citation(s) in RCA: 97] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2014] [Revised: 11/18/2014] [Accepted: 11/18/2014] [Indexed: 02/06/2023]
Abstract
PURPOSE The role of synthetic devices in the management of the cruciate ligament-injured knee remains controversial. The aim of this systematic review was to assess the safety and efficacy of synthetic devices in cruciate ligament surgery. METHODS A systematic review of the electronic databases Medline, Embase, and The Cochrane Library (issue 1, 2014) on January 13, 2014, was performed to identify controlled and uncontrolled trials. Trials that assessed the safety and efficacy of synthetic devices for cruciate ligament surgery were included. The main variables assessed included rates of failure, revision, and noninfective effusion and synovitis. Patient-reported outcome assessments and complications were also assessed where reported. RESULTS From 511 records screened, we included 85 articles published between 1985 and 2013 reporting on 6 synthetic devices (ligament augmentation and reconstruction system [Ligament Augmentation and Reconstruction System (LARS; Surgical Implants and Devices, Arc-sur-Tille, France)]; Leeds-Keio [Xiros (formerly Neoligaments), Leeds, England]; Kennedy ligament augmentation device [3M, St Paul, MN]; Dacron [Stryker, Kalamazoo, MI]; Gore-Tex [W.L. Gore and Associates, Flagstaff, AZ]; and Trevira [Telos (limited liability company), Marburg, Germany]). The heterogeneity of the included studies precluded meta-analysis. The results were analyzed by device and then type of reconstruction (anterior cruciate ligament [ACL]/posterior cruciate ligament [PCL]/combined ACL and PCL). The lowest cumulative rates of failure were seen with the LARS device (2.6% for ACL and 1% for PCL surgery). The highest failure rate was seen in the Dacron ACL group (cumulative rate, 33.6%). Rates of noninfective synovitis and effusion ranged from 0.2% in the LARS ACL group to 27.6% in the Gore-Tex ACL group. Revision rates ranged from 2.6% (LARS) to 11.8% (Trevira-Hochfest; Telos). Recent designs, specifically the LARS, showed good improvement in the outcome scores. The mean preoperative and postoperative Lysholm knee scores were 54 and 88, respectively; the mean preoperative and postoperative Tegner activity scale scores were 3.3 and 6, respectively. CONCLUSIONS Preliminary results for newer-generation devices, specifically the LARS, show lower reported rates of failure, revision, and sterile effusion/synovitis when compared with older devices. LEVEL OF EVIDENCE Level IV, systematic review of Level II through IV studies.
