ACL reconstruction demonstrates better stability compared to ACL repair for patients with Schenck III and IV knee dislocations. Arch Orthop Trauma Surg 2024:10.1007/s00402-024-05532-x. [PMID: 39249137 DOI: 10.1007/s00402-024-05532-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Accepted: 08/31/2024] [Indexed: 09/10/2024]
Abstract
PURPOSE This study compared mid-term outcomes of two anterior cruciate ligament (ACL) restoration techniques within an early total surgical care of acute knee dislocation: repair with additional internal bracing (ACLIB) and reconstruction with autograft (ACLR). Initial results at 12 months demonstrated that ACLR offered superior stability compared to ACLIB. METHODS Retrospective clinical study of patients with acute type III or IV KD. ACLIB or ACLR procedures were performed accompanied by simultaneous suture and internal bracing of the posterior cruciate ligament (PCL) and repair with lateral augmentation of the medial and lateral complex injuries utilizing Arciero's reconstruction technique. Patient-reported outcome measurements (PROMs), instrumental stability assessment via the Rolimeter-Test, and stress radiographs were analyzed. RESULTS The study involved 20 patients (5 IIIM, 5 IIIL, and 10 IV injuries) with an average follow-up of 35.2 ± 7.4 months. Notable differences in anterior tibial translation on stress radiography favouring ACLR persisted at 24-month follow-up in side-to-side difference (SSD) (ACLIB 2.8 ± 2.5 mm vs. ACLR 0.3 ± 2.6 mm; p = 0.0487), but Rolimeter test variance diminished (SSD ACLIB 2.5 ± 0.9 mm vs. ACLR 1.8 ± 1.7 mm). Both groups showed excellent PROMs (Lysholm Score: ACLIB 84.4 ± 15.8 vs. ACLR 89.9 ± 9.0; IKDC Score: ACLIB 77.1 ± 16.2 vs. ACLR 77.7 ± 8.6). CONCLUSION Our results indicate improved anterior stability at 12 months, which persisted at 24 months after ACL reconstruction compared with ACL repair by stress radiography. Both groups showed favourable patient-reported outcomes throughout the follow-up period. Notable rates of postoperative knee stiffness were observed in both groups. These were successfully managed with early, one-time arthroscopic arthrolysis within the first seven months of treatment, resulting in no major range of motion limitations at the 24-month follow-up. LEVEL OF EVIDENCE Retrospective cohort study, III.

Abstract
OBJECTIVES Multiple ligament knee injuries (MLKIs) are disruptive injuries, however, there are controversies in the results of acute and delayed reconstruction. Also, clinical outcomes between patients older or younger than 40 have not been compared in MLKIs. This study was designed to investigate the influence of age and timing of reconstruction on the outcomes of single-stage reconstruction of MLKIs. METHODS The patients who underwent reconstruction of multiple injured ligaments because of MLKIs between May 2013 and July 2019 were added to the cohort. The postoperative complications, knee range of motion (ROM), Lysholm score, International Knee Documentation Committee (IKDC) 2000 score, Tegner activity level, patient satisfaction, and SF-36 score were compared between young (≤ 40 years old, n = 41) and old patients (n = 61); acute (≤ 3 weeks after injury, n = 75) and delayed reconstruction (n = 27), using Mann-Whitney U test or χ2 test. RESULTS A total of 102 MLKI patients managed by single-stage multi-ligament reconstruction were retrospectively reviewed. Patients were followed up after surgery for a mean of 7.3 years (5.2-10.7 years). At the last follow-up, no significant difference was found in knee ROM, functional scores, and patient-reported outcomes between patients older or younger than 40; acute and delayed reconstruction (p > 0.05). The rate of complications in the delayed reconstruction group was higher than that of the acute reconstruction group (22.2% vs 5.3%, p < 0.05). The IKDC objective scores reached grade A in 63.7%-80.4% of patients, and grade B in 11.8%-23.5% patients. CONCLUSION The single-stage reconstruction of MLKIs can obtain comparative long-term functional and objective outcomes regardless of patients older or younger than 40; acute and delayed reconstruction, however, delayed reconstruction is related to a high rate of postoperative complications.

Abstract
INTRODUCTION Multiligament knee injury with posteromedial laxity is serious and usually requires surgery. Reconstruction is preferable to repair. The main aim of the present study was to report clinical results and laximetry for an original posteromedial corner (PMC) allograft reconstruction technique known as The Versailles Technique. The secondary aim was to determine prognostic factors for surgery. The study hypothesis was that anatomic PMC reconstruction by tendon allograft provides satisfactory medium-term clinical and laximetric results. METHODS A retrospective study assessed postoperative clinical and laximetric results after PMC allograft reconstruction at a minimum 12 months' follow-up. Laxity was assessed on comparative bilateral stress X-rays, and functional results on the International Knee Documentation Committee (IKDC) score, the Lysholm score and the Knee injury and Osteoarthritis Outcome Score (KOOS). RESULTS Twenty-six patients were included between 2013 and 2019. Mean follow-up was 27.4±9 months. Mean subjective IKDC score was 69.21±17.36, mean Lysholm score 77.78±14.98 and mean KOOS 66.44±18.52. OBJECTIVE IKDC results were 77% grade A, 22% grade B, and 0% grade C or D. Mean medial differential laxity in forced varus was 0.83±1.26mm. Mean subjective IKDC scores were poorer in Schenck KD-III than KD-I (p=0.03). Functional results were comparable with acute and with chronic laxity. Age correlated inversely with median KOOS (p=0.009). There was no correlation between postoperative radiologic laxity in forced varus and functional results. DISCUSSION Versailles anatomic PMC allograft reconstruction for acute or chronic posteromedial knee laxity showed medium-term efficacy in restoring good objective and subjective stability. LEVEL OF EVIDENCE IV; retrospective observational study.

Abstract
Multiligamentous knee injuries (MLKI) are rare but devastating injuries that have a potential to cause long-term sequelae and significant morbidity. Frequently occurring concomitantly with knee dislocations (KD), MLKI have many risk factors that influence their incidence and treatment outcomes. Proper understanding of these risk factors can assist the surgeon with evaluation, surgical planning, and managing patient expectations both pre- and postoperatively. The purpose of this review is fourfold: (1) identify the risk factors and injuries associated with MLKI, (2) describe factors implicated in the treatment of MLKI, (3) report the effect of these risk factors on outcomes of MLKI, and (4) provide a brief insight into MLKI at our tertiary referral academic care center. This was a retrospective review of literature relevant to MLKI. Studies that described injuries, risk factors, treatment techniques, or outcomes associated with MLKI were included in our review. A total of 35 studies (consisting of level 3 and 4 evidence) published between 2009 and 2020 were found and included in our analysis. In addition, 25 patients who underwent treatment for MLKI at the University of Chicago Medical Center between December 2015 and December 2019 were included in our analysis. MLKI tend to occur in the younger male population. Increasing age, body mass index, and severity of the injury have been correlated with worse functional and patient-reported outcomes. Operative treatment is indicated for MLKI; however, timing and repair versus reconstruction is still debated, and is often decided on a patient by patient basis. Retrospective cohort studies have indicated that reconstruction may be favored; however, further more rigorous studies are needed to better characterize this finding. MLKIs are devastating injuries with significant variability in presentation, treatment, and outcome. Variations in these are largely attributable to the mechanism and severity of injury, timing, and surgeon preference. A holistic approach, and understanding of the present literature, is required to best optimize patient outcome.

Abstract
INTRODUCTION Concomitant patellar tendon (PT) tear with cruciate or multi-ligament knee injuries (MLKI) following high-velocity injury requires a systematic approach. METHODS The study is a retrospective case series of patients (2008-2019) with concomitant PT ligament injury with cruciate or collateral ligament injury (MLKI), including bony avulsion injuries. Isolated cruciate and MLKI without patellar tendon tears are excluded. N = 32 patients (1 female and 31 male) are divided into two groups, Group 1 (11 patients) with PT tear and ACL tear and group 2 (21 patients) with PT tear and MLKIs. Patients were taken up for a single stage in types 1,2,3 and staged repair with reconstruction for types 4,5 of our new classification. All the patients are followed up regularly, and IKDC and Lyshom's score and objective radiological stress x-rays taken at each follow-up RESULTS: Incidence of PTT combined injuries among all knee ligament injuries is 0.57%. The mean age was 35.09+/-11.96 SD(group1) and 36.55+/-11.89 SD(group2). The average follow-up was 34.45 months +/- 12.86SD (group 1) and 35.3 months +/- 15.75 SD (group2). Mean post-operative Lysholm score and IKDC score of group 1 and group 2 improvement was statistically significant p-value <=0.01. The mean post-operative ROM of the two groups were 132.73 (SD 6.46) (Group 1) and 111.75 (15.75) (Group 2) and was a statistically significant p-value <0.01. Residual lag of 30° seen in all patients improved by 3rd month in group 1 and 6th month in group 2. Knee stiffness is seen in 2 patients and superficial infection in 2 patients. CONCLUSION PTT combined injuries are rare and occurs due to direct impact injuries. Single-stage PT repair with ACL reconstruction gives adequate stability, and extensor lag is eminent and needs supervised rehabilitation. PT with MLKI is a challenging scenario that can be performed in single-stage/multiple stages, depending on the injuries, surgical expertise, and institutional facilities. Newer simplified classification aids surgeons in planning a treatment strategy.

The anterior cruciate ligament injury severity scale (ACLISS) is an effective tool to document and categorize the magnitude of associated tissue damage in knees after primary ACL injury and reconstruction. Knee Surg Sports Traumatol Arthrosc 2023:10.1007/s00167-023-07311-4. [PMID: 36629888 DOI: 10.1007/s00167-023-07311-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 01/02/2023] [Indexed: 01/12/2023]
Abstract
PURPOSE To develop a tool allowing to classify the magnitude of structural tissue damage occurring in ACL injured knees. The proposed ACL Injury Severity Scale (ACLISS) would provide an easy description and categorization of the wide spectrum of injuries in patients undergoing primary ACL reconstruction, reaching from isolated ACL tears to ACL injuries with a complex association of combined structural damage. METHODS A stepwise approach was used to develop the ACLISS. The eligibility of each item was based on a literature search and a consensus between the authors after considering the diagnostic modalities and clinical importance of associated injuries to the menisci, subchondral bone, articular cartilage or collateral ligaments. Then, a retrospective analysis of associated injuries was performed in 100 patients who underwent a primary ACL reconstruction (ACLR) by a single surgeon. This was based on acute preoperative MRI (within 8 weeks after injury) as well as intraoperative arthroscopic findings. Depending on their prevalence, the number of selected items was reduced. Finally, an analysis of the overall scale distribution was performed to classify the patients according to different injury profiles. RESULTS A final scoring system of 12 points was developed (12 = highest severity). Six points were attributed to the medial and lateral tibiofemoral compartment respectively. The amount of associated injuries increased with ACLISS grading. The median scale value was 4.5 (lower quartile 3.0; higher quartile 7.0). Based on these quartiles, a score < 4 was considered to be an injury of mild severity (grade I), a score between ≥ 4 and ≤ 7 was defined as moderately severe (grade II) and a score > 7 displayed the most severe cases of ACL injuries (grade III). The knees were graded ACLISS I in 35%, ACLISS II in 49% and ACLISS III in 16% of patients. Overall, damage to the lateral tibiofemoral compartment was predominant (p < 0.01), but a proportional increase of tissue damage could be observed in the medial tibiofemoral compartment with the severity of ACLISS grading (p < 0.01). CONCLUSIONS The ACLISS allowed to easily and rapidly identify different injury severity profiles in patients who underwent primary ACLR. Injury severity was associated with an increased involvement of the medial tibiofemoral compartment. The ACLISS is convenient to use in daily clinical practice and represents a feasible grading and documentation tool for a reproducible comparison of clinical data in ACL injured patients.

Abstract
INTRODUCTION Current classifications of complete knee dislocations do not capture the extent of the complex concomitant ligamentous and bony injuries, which may have an impact on future outcomes. The purpose of this retrospective study was to evaluate the epidemiology of complete knee dislocations as well as to present an updated classification system based on the author's experience at a Level-I trauma center. MATERIALS AND METHODS Only patients with complete loss of contact of the articulating bones and ≥ 18 years of age who admitted in our level-I trauma center between 2002 and 2019 were included. Patients were identified using a retrospective systematical query in the Hospital Information System (HIS) using the International Statistical Classification of Diseases and Related Health Problems Version10 (ICD-10) codes of the German Diagnosis Related Groups (G-DRG). RESULTS Final data included 80 patients, with the majority of patients being male (n = 64; 80.0%). Mean age was 34.9 years (range: 18-70 years). External protective fixation was applied in 32 patients (40.0%). Reconstruction of the posterior cruciate ligament and the anterior cruciate ligament were performed in 56.3% (n = 45) and 55.0% (n = 44) of cases, respectively. The lateral collateral ligament complex was surgically addressed in 47.5% (n = 38), while the medial collateral ligament complex was reconstructed in 40% (n = 32). Surgery of the lateral meniscus and the medial meniscus was needed in 31.1% (n = 25) and 30.0% (n = 24). Neurovascular surgery occurred in 13.8% (n = 11). From the characteristic injury-patterns the authors of this study present a new classification system that ranks the injuries from Grade-A to Grade-D according to their severity. CONCLUSION This retrospective study demonstrates that the historically used classification systems for dislocations of the knee are insufficient for these severe injuries. Concomitant ligamentous, neurovascular, bony, and meniscal injuries were frequent, and required several staged procedures. Consequently, an updated classification system is proposed.

Abstract
INTRODUCTION At present, limited knowledge regarding clinical, functional, and patient-reported outcomes at mid- and long-terms after surgical treatment of traumatic knee dislocations is available. This study aimed to investigate the mid-term recovery regarding clinical, functional, and patient-reported outcomes in patients following knee dislocation with associated multi-ligament injuries. MATERIALS AND METHODS The study design was a cross-sectional cohort study. Data were collected by retrospective chart review, clinical examination, and interview of patients. All patients treated surgically following a knee dislocation between January 2000 and December 2011 were included. The surgical technique was up to the decision of the individual surgeon. The main outcome was the Lysholm knee score. Secondary outcomes consist of clinical knee examination, functional performance test, pain, and patient-reported outcome across several domains in function, sport, pain, and quality of life. RESULTS Seventy-five patients (66.3%) accepted the invitation to participate. The mean age at the time of knee dislocation was 33.5 years, with a range of 16-65 years of age. The mean follow-up time was 78 months (R: 17-147). 75% of patient a Schenck's type 1 lesion and 23% a type 3. The median Lysholm knee score was 83 (R: 18-100). The mean KOOS for the five subscales were pain 84.5 (95% CI 80.5-88.5), symptoms 75.1 (95% CI 70.7-79.4), ADL 87.0 (95% CI 83.1-90.9), sport 59.9 (95% CI 53.3-66.4), and QOL 71.3 (95% CI 67.0-75.6). The mean Tegner activity level was 5.1 (95% CI 4.5-5.7). The median single assessment numeric evaluation (SANE) was 93 (R: 0-100). The pain intensity score for pain (VAS) during activity was reported with a mean of 2.7 (95% CI 2.1-3.3). The objective IKDC examination showed 76% of patients grouped by Grade A (normal knee function) or Grade B (nearly normal). CONCLUSION With a mean follow-up of 6.5 years, combined repair and reconstruction surgery following a knee dislocation shows good to excellent patient-reported outcome and more than 75% of patients experiencing normal knee functioned evaluated by the IKDC score.

Abstract
The aim of this study was to evaluate the incidence of knee osteoarthritis, failure rate of reconstruction, and clinical outcomes of patients with chronic multiligament knee injuries subjected to surgical treatment. Sixty-two patients with chronic knee dislocation subjected to multiligament reconstruction between April 2008 and July 2016 were evaluated, with a minimum follow-up of 24 months. Anteroposterior and lateral radiographs were performed in the pre- and last postoperative evaluation; the progression of degenerative changes according to the Kellgren-Lawrence classification (KL) was assessed. The Schenck classification, Knee Injury and Osteoarthritis Outcome Score (KOOS), time between injury and surgery, type of postoperative rehabilitation protocol (brace vs. external fixator), and physical examination for ligament instability were also evaluated. Univariate and multivariate analysis were performed, p <0.05 was considered significant. Fifty-two (83.9%) patients were men and 16.1% (n = 10) were women, with a mean age of 38.8 ± 1.3 years. The time from injury to surgery was 31.1 ± 6.1 months, and the follow-up time was 6.1 ± 0.5 years. The mean final KOOS was 79.3 ± 10.4 and the overall reconstruction failure occurred in 25.8%. Of all patients, 64.5% (n = 40) presented a KL classification of ≥2 and were defined as having radiographic osteoarthritis (OA). As 11.7% (n = 7) also presented arthritis in the contralateral knee, in 53.2% (n = 33) the progression was most likely due to the initial injury. The failure of ligament reconstruction or residual instability was present in 15 (35.7%) of patients with OA, and only one patient (4.5%) without OA. In the multivariate analysis, only reconstruction failure was an independent predictor of OA (odds ratio = 13.2 [p = 0.028]). There is a high incidence of knee OA following ligament reconstruction for chronic multiligament knee injuries. Ligament reconstruction failure was the only independent predictor for the development of OA in our study.

Abstract
INTRODUCTION Multiligament knee injuries are a rare but serious injury, affecting functional prognosis. The objective of this study was to assess the long-term clinical and laximetric outcomes of acute or chronic multiligament knee reconstructions, with lateral impairment, using autografts. HYPOTHESIS Autograft reconstructions give good long-term clinical and laximetric results. MATERIAL AND METHOD A retrospective monocentric consecutive study was conducted in patients who had multiligament knee reconstructions. The criteria for inclusions were cruciate ligament lesions associated with lateral injuries, reconstructed using autografts, regardless of the time to surgery. A minimum follow-up of 5-years was required. Twenty-nine patients were analysed. The average age at surgery was 30.2±13 years. The patients were clinically reviewed at the last follow-up. Differential residual laxity was objectively assessed with comparative dynamic X-rays. Functional IKDC, Lysholm and KOOS scores were analyzed. RESULTS The average follow-up was 7.5±1.7 years. The lesions were divided into 12 KD-I, 16 KD-IIIL and 1 KD-IV, including 16 acute lesions (time to surgery <30-day) and 13 chronic lesions. At the last follow-up, the objective IKDC identified: 3 stage A, 15 stage B and 11 stage C. The average scores were: subjective IKDC 70.1±16, Lysholm 76.8±14 and KOOS: pain 71.6±20, symptoms 83.6±22, activity 90.6±20, sport 58.8±23, quality of life 60.0±30. Dynamic X-rays showed an average differential laxity of 2.8±2.6mm anteriorly, 5.0±2.2mm posteriorly, and 2.0±2.5mm in varus. Four cases required surgery: 3 arthrolysis procedures for stiffness and 1 joint lavage for sepsis. DISCUSSION With an average follow-up of 7.5 years, multiligament knee reconstructions using autografts with lateral involvement provide good long-term control of frontal and sagittal laxities. A comparison with allograft reconstructions is necessary to be able to potentially overcome the morbidity associated to donor sites. LEVEL OF EVIDENCE IV; monocentric retrospective descriptive study.

Abstract
OBJECTIVE To explore the effectiveness of one-stage posterior medial corner (PMC) repair or reconstruction combined with anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction in treating KD-ⅢM dislocation. METHODS The clinical data of 15 patients with knee KD-ⅢM dislocation who met the selection criteria between January 2016 and July 2019 were retrospectively analyzed. There were 9 males and 6 females, aged 22-61 years (mean, 40.3 years). Injuries were caused by violence of flexion, valgus, and external rotation, including 10 cases of traffic accident injuries, 3 cases of crush injuries, 1 case of winch injury, and 1 case of explosion injury. The time from injury to operation ranged from 3 days to 6 months, with an average of 18.5 days. PMC repair combined with PCL+ACL reconstruction was performed in 10 cases in acute stage (within 3 weeks after injury), including 3 cases of irreducible dislocation. PMC+PCL+ACL reconstruction was performed in 5 cases with chronic dislocation. Before operation and at last follow-up, the knee joint function was evaluated by Lysholm score and International Knee Documentation Committee (IKDC) 2000 score. KT-3000 was used to evaluate the forward stability of the knee (calculated the difference of tibial anterior displacement of both knees), the X-ray films of the stress position of the knee joint was used to evaluate the valgus of the knee (calculated the difference of medial joint space width of both knees) and the backward stability (calculated the difference of tibial posterior displacement of both knees), and the internal and external rotation stability was evaluated by knee flexion 30° tibial external rotation and knee flexion 90° tibial internal rotation tests (calculated the difference of tibial internal rotation and the difference of tibial external rotation of both knees). RESULTS The operation time was 120-240 minutes, with an average of 186.5 minutes. Patients were followed up 24-48 months, with an average of 27.4 months. There was no complication such as infection, deep vein thrombosis, vascular injury, or heterotopic ossification. At last follow-up, the Lysholm score, IKDC2000 score, the difference of tibial anterior displacement of both knees, the difference of medial joint space width of both knees, the difference of tibial posterior displacement of both knees, the difference of tibial internal rotation and the difference of tibial external rotation of both knees significantly improved when compared with preoperative ones ( P<0.05). According to the IKDC2000 valgus stability grading standard, there were 3 cases of grade C and 12 cases of grade D before operation, and 10 cases of grade A and 5 cases of grade B at last follow-up, which was significantly improved when compared with that before operation ( Z=-4.930, P=0.000). At last follow-up, the pivot shift tests of 15 patients were negative. The anterior and posterior drawer tests of 10 patients were negative, 5 patients had mild instability, both the anterior and posterior drawer tests were positive. CONCLUSION KD-ⅢM dislocation of the knee joint can lead to the posterior medial and anterior instability. Acute dislocation combined with "dimple sign" requires surgical reduction as soon as possible to repair PMC and reconstruct PCL and ACL. In chronic patients, PMC is difficult to repair, it is recommended to reconstruct PMC, PCL, and ACL at one stage to improve knee joint stability. The early and middle effectiveness are satisfactory.

The accuracy of MRI in diagnosing and classifying acute traumatic multiple ligament knee injuries. BMC Musculoskelet Disord 2022; 23:43. [PMID: 35027036 PMCID: PMC8756613 DOI: 10.1186/s12891-021-04976-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 12/20/2021] [Indexed: 11/28/2022] Open
Abstract
Background Magnetic resonance imaging (MRI) is widely used for the evaluation of knee injuries, however, the accuracy of MRI in classifying multiple ligament knee injuries (MLKIs) remains unknown. This study aimed to investigate the accuracy of MRI in diagnosing and classifying acute traumatic MLKIs, we hypothesize that MRI had high accuracy in detecting and classifying MLKIs. Methods The clinical data of 97 patients who were diagnosed with acute traumatic MLKIs and managed by multi-ligament reconstruction between 2012 and 2020 were retrospectively reviewed. The MR images were read by two experienced radiologists and results were compared with intraoperative findings, which were considered as the reference for the identification of injured structures. The value of MRI in detecting injuries of anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), lateral collateral ligament (LCL), and meniscus was evaluated by calculating the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and kappa coefficients analysis. The value of MRI in classifying MLKIs was evaluated by calculating the agreement between MRI and intraoperative findings. Results For detecting the specific injured structures in MLKIs, MRI had high sensitivity (90.7% for ACL, 90.4% for PCL, and moderate specificity (63.6% for ACL, 50% for PCL) in detecting cruciate ligament injuries, moderate sensitivity (79.1% for MCL, 55.6% for LCL) and specificity (46.7% for MCL, 68.4% for LCL) in detecting collateral ligament injuries, fair sensitivity (61.5%) and low specificity (39.4%) in the diagnosis of injuries to the meniscus. For classifying the MIKIs, MRI had a moderate agreement with intraoperative findings in classifying KD-V (kappa value = 0.57), poor agreement in the KD-I (kappa value = 0.39) and KD-IIIM (kappa value = 0.31), meaningless in the KD-II and KD-IIIL (kappa value < 0). The overall agreement between MRI and intraoperative findings in classifying MLKIs was poor (kappa value = 0.23). Conclusions MRI is valuable in early detection and diagnosis of acute MLKIs, however, the accuracy of MRI in classifying MLKIs is limited. The management of MLKIs should be based on intraoperative findings, physical examinations, and comprehensive imaging results.

Abstract
Multiligament knee injuries (MLKIs) are debilitating injuries that increasingly occur in young athletes. Return to sport (RTS) has historically been considered unlikely due to the severity of these injuries. Reporting in the literature regarding objective outcomes following MLKI, including RTS, is lacking, as are clear protocols for both rehabilitation progressions and RTS testing. RTS following MLKI is a complex process that requires an extended recovery duration compared to other surgery types. Progressions through postoperative rehabilitation and RTS should be thoughtful, gradual, and criterion based. After effective anatomic reconstruction to restore joint stability, objective measures of recovery including range of motion, strength, movement quality, power, and overall conditioning guide decision-making throughout the recovery process. It is important to frame the recovery process of the athlete in the context of the severity of their injury, as it is typically slower and less linear. Improved reporting on objective outcomes will enhance our understanding of recovery expectations within this population by highlighting persistent deficits that may interfere with a full recovery, including RTS.

Abstract
Background: The optimal timing of surgical intervention for multiligament knee injuries remains controversial. Purpose: To review the clinical and functional outcomes after acute and delayed surgical intervention for multiligament knee injuries. Study Design: Systematic review; Level of evidence, 4. Methods: We performed a search of the PubMed, Embase, Cochrane Library, and Web of Science databases from inception to September 2020. Eligible studies reported on knee dislocations, multiligament knee injuries, or bicruciate ligament injuries in adult patients (age, ≥18 years). In addition to comparing outcomes between acute and delayed surgical intervention groups, we conducted 3 subgroup analyses for outcomes within isolated knee injuries, knee injuries with concomitant polytrauma/fractures, and high-level (level 2) studies. Results: Included in the analysis were 31 studies, designated as evidence level 2 (n = 3), level 3 (n = 8), and level 4 (n = 20). These studies reported on 2594 multiligament knee injuries sustained by 2585 patients (mean age, 25.1-65.3 years; mean follow-up, 12-157.2 months). At the latest follow-up timepoint, the mean Lysholm (n = 375), International Knee Documentation Committee (IKDC) (n = 286), and Tegner (n = 129) scores for the acute surgical intervention group were 73.60, 67.61, and 5.06, respectively. For the delayed surgical intervention group, the mean Lysholm (n = 196), IKDC (n = 172), and Tegner (n = 74) scores were 85.23, 72.32, and 4.85, respectively. The mean Lysholm (n = 323), IKDC (n = 236), and Tegner (n = 143) scores for our isolated subgroup were 83.7, 74.8, and 5.0, respectively. By comparison, the mean Lysholm (n = 270), IKDC (n = 236), and Tegner (n = 206) scores for the polytrauma/fractures subgroup were 83.3, 64.5, and 5.0, respectively. Conclusion: The results of our systematic review did not elucidate whether acute or delayed surgical intervention produced superior clinical and functional outcomes. Although previous evidence has supported acute surgical intervention, future prospective randomized controlled trials and matched cohort studies must be completed to confirm these findings.

Abstract
OBJECTIVE Stepwise reconstruction of knee stability and physiological kinematics in acute knee dislocation. INDICATIONS The operative technique is demonstrated in a case of multiligamentous injury of the knee with involvement of both cruciate ligaments and additional medial and lateral peripheral injuries (type IV according to Schenck classification). CONTRAINDICATIONS Critical soft tissue conditions, infections, old age, obesity, lack of compliance. SURGICAL TECHNIQUE Time-limited arthroscopy in order to primarily identify and treat posterior horn/root injuries of the meniscus and concomitant intra-articular injuries. Anatomical placement of anterior cruciate ligament (ACL) drill wires for later ACL tunnel drilling is arthroscopically guided. Subsequent conversion to an anteromedial arthrotomy and ligament bracing of the posterior cruciate ligament. The ACL is reconstructed using the ipsilateral semitendinosus tendon. Medial and lateral peripheral injures are anatomically reconstructed followed by a posterolateral augmentation in a technique described by Arciero. FOLLOW-UP Limited weight bearing for 6 weeks and stepwise increase of flexion using a standard knee brace and close clinical monitoring. EVIDENCE Ligament bracing of both cruciate ligaments is an established treatment technique in acute knee dislocations and has been proven to achieve good to excellent clinical results. In an ongoing clinical study primary ACL reconstruction as a modified treatment approach indicated superior stability in a 12-month follow-up in patients with acute knee dislocations.

Abstract
Introduction Multiligament knee injuries are uncommon but serious injuries. There is ongoing debate on the optimal treatment of these injuries. We designed a study to establish the effects of repair or reconstruction on proprioceptive outcomes following multiligament injury to the knee. Materials and Methods A total of 34 patients were analysed by independent researchers who had no conflict of interest in the cases (23 in the repair group and 11 in the reconstruction group). Proprioception of the knee was measured using a previously validated tool to assess the reproduction of passive positioning. Functional outcome was measured using the Lysholm score. Sub-group analysis was performed. The mean time from injury to review was 83 months (range: 25-193 months). Results There were no significant differences in proprioceptive acuity between the injured (5.9±4.2°; range: 1.0-18.3°) and uninjured contralateral (control) knees (5.2±3.8°; range: 1.0-15.0°; p=0.35). Similarly, there was no significant difference in proprioceptive acuity identified between the injured knees that underwent repair (6.0±4.3°; range: 1.0-18.3°) or reconstruction (5.0±3.6°; range: 1.3-14°; p=0.53). Overall knee outcomes were good; the mean Lysholm score at final follow-up was 75.5±16.8 (range: 36-100). No significant differences were identified in any of the sub-groups. Conclusions We were unable to identify any differences in knee proprioceptive acuity between injured knees and controls nor between the types of surgical treatment, demonstrating equivocal recovery for both methods of treatment.

Abstract
PURPOSE The proximal tibiofibular joint (PTJF) can be injured with the structures in the lateral aspect of the knee in a multi-ligament knee injury (MLKI) patient. Such injuries are scarce but require attention in the management of the complex MLKIs. The assessment and management of such injuries are not well described in the English literature. This study describes the frequency of PTFJ injuries, clinical assessment and functional outcomes of such injuries in MLKI patients. METHODOLOGY The data were collected retrospectively from the cohort from 2013 to 2018. The 84 MLKI were included in the study, out of which 9 patients had associated PTFJ injury. All the PTFJ injuries were operated by one single surgeon (D.S) which involves stabilization with K-wires (Kirschner wire) and fixation with 4 mm cancellous cannulated screw along with reconstruction surgery for MLKI in single stage. RESULTS The frequency of PTFJ injury in our patient cohort is 10.71%. Three patients out of the nine patients received Larson procedure apart from the fixation of PTFJ. At a mean follow-up of 13 months, the Lysholm score was 77.4 (range: 69-86) and mean modified Cincinnati score was 62 (range: 52-72). There was grade I posterior laxity present in one patient with PCL and PLC injury, one patient with ACL, PCL and PLC injury, and one patient with ACL, PCL, MCL and PLC injury at final follow-up. Terminal flexion of 15° or more restriction was noted in six patients. All patients were satisfied with the outcome. CONCLUSION Evaluation of PTFJ should be an integral part of preoperative as well as an intraoperative examination of MLKI patients. The fixation of this joint is of utmost importance for the reconstructive ligament procedures on the lateral aspect of the knee. The dial test used for the assessment of the integrity of PLC injury should have a prerequisite of proximal tibiofibular joint stability, otherwise, it can lead to erroneous assessment.

Multiligament knee injuries treated by one-stage reconstruction using allograft: Postoperative laxity assessment using stress radiography and clinical outcomes. Orthop Traumatol Surg Res 2020; 106:937-944. [PMID: 31494067 DOI: 10.1016/j.otsr.2019.08.001] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2018] [Revised: 06/28/2019] [Accepted: 08/24/2019] [Indexed: 02/03/2023]
Abstract
BACKGROUND Surgical treatment of multiligament knee injuries (MLKIs) leads to better outcomes but there are controversies about optimal surgical strategies. Debates remain about timing of surgery: acute, staged or delayed and about graft choice: autograft, allograft or a combination of both. Therefore, we performed a retrospective study aiming to evaluate postoperative laxity using stress radiographs and clinical outcomes after one-stage reconstructions of injured ligaments using non-irradiated, fresh-frozen allografts. HYPOTHESIS MLKIs treated by one-stage reconstructions using non-irradiated, fresh-frozen allograft may lead to satisfactorily postoperative laxity and clinical outcomes. METHODS Between November 2013 and July 2015, 23 patients with MLKIs underwent one-stage reconstruction using allograft. Knee injuries were defined according Schenk classification of Knee Dislocation (KD). Patients were evaluated using the Knee injury and Osteoarthritis Outcome Score (KOOS), the Lysholm Knee Scoring Scale, and the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form at a minimum follow-up of 24 months. Postoperative anterior, posterior, varus, and valgus laxities were assessed using stress radiographs and expressed as side-to-side differences (SSD) in millimeters. RESULTS Three of 23 patients were lost to follow-up. There were 6 KD-I, 12 KD-III, and 2 KD-IV lesions, 12 lateral-side and 10 medial-side lesions, and 13 acute and 7 chronic cases. Three patients had associated neurovascular injuries. Mean follow-up was at 29.4±6.1 months. Mean valgus SSD was 0.2mm±1.4mm (range, -2.1-2.2mm), mean varus SSD was 1.4mm±2.5mm (range, -1.7-6.0mm), mean posterior SSD was 7.2mm±3.9mm (range, 1.2-16.0mm), mean anterior SSD was 3.6mm±5.1mm (range, -4.8-16.8mm). Overall IKDC ratings were: 4 grade A, 3B, 7C, and 6D. Three patients complained of postoperative instability, with an IKDC rating of D. The mean subjective IKDC score was 67.2±19.6, the mean Lysholm Knee Scoring Scale was 77.3±16.5, and the mean KOOS results were 78.5±16.6 for pain, 67.7±17.4 for symptoms, 86.5±14.2 for daily activities, 56±25.4 for sports, and 47.2±28.6 for quality of life. Nineteen of 20 patients returned to sport-6 to the same level. One patient underwent an arthroscopic arthrolysis due to postoperative arthrofibrosis. CONCLUSIONS Using non-irradiated allografts for one-stage reconstructions of all the injured ligaments in MLKIs is effective and safe. Anteroposterior stability was difficult to restore, but patients returned to their daily activities and sometimes to their sports activity at the same preinjury level. LEVEL OF EVIDENCE Level IV, case series.

Abstract
BACKGROUD Multi-ligamentous knee injuries have been a grey area due to unavailability of large scale control trials with a long term follow up. Several studies have documented good results with different protocols of management regarding time of treatment, repair versus reconstruction, choice of graft and sequence of repair. The author wishes to put forward long-term results of early (<6 weeks) single-stage surgery in multi ligamentous injuries. METHODS The prospective trial included 29 patients diagnosed with three or more ligaments involved. Patients having fractures involving proximal tibia, distal femur, patella, patients with history of compound trauma to knee, osteochondral lesions, associated neuro-vascular injury & poly-trauma patients were excluded from the study. The patients also underwent AP, lateral & stress skiagrams in addition to a standard 3T MR scan for pre-operative planning and confirmation of diagnosis. The pre & post-operative outcomes were assessed using KSS & Lysholm score. The patients were followed up for two years with clinical examination and stress skiagrams. RESULTS The mean increase in knee scores was statistically significant at both 12 months and 24 months (p < 0.05) with mean ROM of 132.8° at final follow-up. Three patients required manipulation under anaesthesia. All patients could carry out their activities of daily living at mean period of 8.2 months. Osteoarthritis was most common complication at 2 years follow-up. CONCLUSION The most important aspect of a single stage reconstruction lies in earlier restoration of function with a tremendous decrease in loss of medical expenses, improvement of quality of life and early & improved function in terms of both physical and psychological factors. Better restoration of kinematics from early rehabilitation is probably the factor responsible for the results. Osteoarthritis remains an important follow-up finding.

Abstract
PURPOSE This study aims to identify multiple ligament knee injury patterns that possess a high-risk of vascular lesion. METHODS We retrospectively compared torn ligament patterns and the presence of vascular lesions confirmed by magnetic resonance imaging and computed tomography angiography from 122 consecutive patients with diagnoses of multiple ligament knee injury made at the emergency department between January 2012 and December 2017. Patients were not eligible if they had an ipsilateral lower extremity lesion (dislocations or fractures at another level), initial evaluation at another hospital, or follow-up for less than 12 months. The primary outcomes were the comparison between the imaging findings of torn structures patterns and the presence of a vascular lesion. RESULTS We identified 48 eligible patients (50 knees) with multiligamentary knee lesions, of whom eight had popliteal artery damage, yielding an incidence of 16%. Our clinical examination detected six of these patients that were classified, according to the Schenck system, as KD-IIIL (6 knees) and KD-IIIM (2 knees). The odds of having a popliteal artery injury is 4.69 to 1 with a KD-IIIL injury that with any other type of injury on that classification (95% CI 0.960-22.98). CONCLUSIONS This data suggests that varus forces causing enough energy to produce a KD-IIIL lesion possess a higher popliteal artery injury risk, making recommendable a thorough examination of the vascular integrity when diagnosing a KD-IIIL lesion.

Abstract
BACKGROUND Knee dislocations are a potentially limb-threatening injury, and it is essential that emergency medicine clinicians are aware of them. OBJECTIVE This article provides a review of the diagnosis and management of knee dislocation for the emergency provider. DISCUSSION Knee dislocations are uncommon injuries with the potential for significant morbidity. A thorough history and examination are important, because 50% of dislocations may have reduced before arrival to the emergency department. Knee dislocations should be quickly reduced in the emergency department setting. The presence of equal pulses does not exclude vascular injury, and all patients should undergo serial vascular examinations and evaluation with ankle-brachial indices. Those with abnormal ankle-brachial indices should receive computed tomographic angiography. Radiographs are important to identify any fractures, while magnetic resonance imaging may be deferred until after admission. CONCLUSION Knee dislocation is a potentially dangerous medical condition requiring rapid diagnosis and management. It is essential for emergency clinicians to know how to diagnose and treat this disorder.

Abstract
Knee dislocation is one of the few real orthopaedic emergencies. It is a serious but relative uncommon injury, representing less than 0.02% of all orthopaedic injuries. Especially posterolateral knee dislocation is much rarer condition that is often missed or misdiagnosed. The main feature of this very rare condition is to be irreducible by closed reduction due to the interposition of soft tissues inside the enlarged medial joint space, such as the medial capsule and retinaculum, vastusmedialis, and medial meniscus. The pathognomonic sign of a posterolateral knee dislocation is the anteromedial distal thigh transverse "pucker" or "dimple sign." We report the case of an 87-year-old man who sustained an irreducible posterolateral fracture dislocation of the knee after being hit by car which has been treated with rotating hinge knee replacement with 1-year of follow-up.

Factors predictive of poorer outcomes in the surgical repair of multiligament knee injuries. Knee Surg Sports Traumatol Arthrosc 2019; 27:445-459.

Abstract
PURPOSE To investigate the influence of injury and treatment factors on clinical/functional outcomes in multiligament knee injuries (MLKI). METHODS Thirty-nine consecutive patients with confirmed and surgically treated MLKI who met inclusion criteria were scheduled for a follow-up visit to obtain: SF-12 and subjective feeling of normalcy between the operated and healthy knee, and IKDC, active range of motion (ROM), and stability exam (Lachman test, posterior drawer, and dial test at 30°). A chart review was used to obtain data on injury and treatment factors. RESULTS The postoperative mean (SD) outcomes were: IKDC score 62.7 (25.9), flexion-extension ROM 125° (29°), and percentage of normalcy 74% (20%). The postoperative normal/nearly normal stability exam was: Lachman test 36 (95%) patients, posterior drawer at 90° 38 (97%) patients, and dial test of 39 (100%) patients. There were 24 (61.5%) and 23 (59%) patients with complications and reoperations, respectively. The presence of bicruciate injuries was associated with worse Lachman (p = 0.03) and posterior drawer tests (p = 0.03). Presence of injury to meniscal structures was associated with worse Lachman test (p = 0.03), lower percentage of normalcy (p = 0.02) and extension lag (p = 0.04). Injury to cartilage structures was associated with worse IKDC scores (p = 0.04). IKDC was lower in cases of posterolateral corner reconstruction (p = 0.03) and use of allograft tendons for reconstruction (p = 0.02); ROM was lower in allograft reconstruction (p = 0.02) and need for meniscal repair (p = 0.01). Bicruciate reconstruction led to worst posterior drawer test (p = 0.006). CONCLUSIONS The outcomes of MLKI might be negatively influenced by bicruciate ligament, meniscal, and cartilage injuries; with regards to treatment characteristics, need for posterolateral corner or bicruciate ligament reconstruction, use of allografts, or need for meniscal repair may similarly diminish outcomes. While surgical treatment provides good overall function, ROM and stability, it rarely results in a "normal" knee and the chances of complications and reoperations are high.

Meniscal root tears occur frequently in multi-ligament knee injury and can be predicted by associated MRI injury patterns. Knee Surg Sports Traumatol Arthrosc 2018; 26:3731-3737.

Abstract
PURPOSE The frequency of meniscal root tears in association with multi-ligament knee injury has not been established but adds to the complexity of surgical reconstruction and may have long-term consequences. Therefore, identifying root tears, on preoperative imaging, is important. The aim of this study was to identify the frequency of meniscal root tears, on preoperative magnetic resonance imaging, following multi-ligament injury and distinguish associated injury patterns that may aid detection. METHODS Cases were identified from a prospectively collected institutional database. The magnetic resonance imaging of 188 multi-ligament injuries [median age 31 years (range 16-64)] was retrospectively reviewed by three musculoskeletal radiologists with the presence of meniscal injuries recorded alongside the ligament injury pattern and intra-articular fractures. Assessment of injury pattern was solely made on this imaging. RESULTS 38 meniscal root injuries were identified in 37 knees (overall frequency = 20.2%; medial = 10.6%; lateral = 9.6%). The frequency of meniscal root tears was not increased in higher grade injuries (21.5% vs. 17.0%, n.s.). Valgus injury patterns were associated with lateral root tears (p < 0.05) and varus patterns were associated with medial root tears (p < 0.05). Further, fractures in the same compartment were associated with both medial and lateral root tears (p < 0.05). CONCLUSIONS Meniscal root tears occur more frequently in multi-ligament knee injury than previously reported with isolated anterior cruciate rupture. Root tears can be predicted by ligament injury patterns and fractures sustained (suggestive of a compressive force). In multi-ligament cases, the preoperative magnetic resonance imaging can be used to detect these tears and associated patterns of injury. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND AND PURPOSE Traumatic dislocation of the knee (TKD) is a rare injury, accounting for approximately 0.02% of orthopaedic injuries. They are a challenging entity for orthopaedic surgeons to manage, and can have devastating consequences. The aim of this study was to describe the epidemiology of traumatic knee dislocations (TKD'S) and contrast the incidence of neurovascular injury between isolated and multi-trauma dislocations as well as key patient reported outcomes achieved between these groups. MATERIAL AND METHODS Patients who had a traumatic disruption of the tibiofemoral articulation between March 1 2007 and February 31, 2015 were identified from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Data was cross-checked with medical records and radiological reports to confirm true multi-ligamentous dislocation. VOTOR collects information pertaining to orthopaedic injuries, treatment, complications and outcomes from four adult hospitals in Victoria, Australia, including the major trauma centers. Patient-reported outcomes are collected by VOTOR at 12 months post-injury including the EQ-5D-3L (EQ-5D) and Glasgow Extended Outcome Scores (GOS-E) and return to work status. Patient reported functional and quality of life outcomes at 12 months after injury were analysed. RESULTS A cohort of 88 patients were identified that fit the inclusion criteria for the study, and at 12 months post-injury there was data available for 80 patients (90.9%). There were 38 (42.9%) patients who experienced an isolated traumatic knee dislocation and 52 (57.1%) who experienced a traumatic knee dislocation in association with another injury. Of the 88 patients identified as eligible for the study, two had bilateral knee dislocations, hence there were 90 multi-ligamentous knee injuries. Those who were injured at a higher velocity were more likely to have additional injuries. Dislocations that occurred at a lower velocity were shown to have better overall outcomes, as did dislocations that occurred in isolation. CONCLUSIONS Traumatic knee dislocations that occur in isolation typically result in better outcomes than those that occur with associated injuries. TKD's are a rare but severe injury that requires further research in order for functional outcomes to be optimized.

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.

Abstract
Traumatic knee dislocation is a rare but potentially limb-threatening injury. Thus proper initial diagnosis and treatment up to final ligament reconstruction are extremely important and a precondition to successful outcomes. Reports suggest that evidence-based systematic approaches lead to better results. Because of the complexity of this injury and the inhomogeneity of related literature, there are still various controversies and knowledge gaps regarding decision-making and step-sequencing in the treatment of acute multi-ligament knee injuries and knee dislocations. The use of ankle-brachial index, routine or selective angiography, braces, joint-spanning or dynamic external fixation, and the necessity of initial ligament re-fixation during acute surgery constitutes current topics of a scholarly debate. The aim of this article was to provide a comprehensive literature review bringing light into some important aspects about the initial treatment of knee dislocation (vascular injury, neural injury, immobilization techniques) and finally develop an accurate data-based universal algorithm, enabling attending physicians to become more acquainted with the management of acute knee dislocation.

Abstract
BACKGROUND Knee dislocations often require multiple concurrent ligament reconstructions, which involve creating several tunnels in the distal femur. Therefore, the risk of tunnel convergence is increased because of the limited bone volume within the distal aspect of the femur. PURPOSE To assess the risk of tunnel convergence and determine the optimal reconstruction tunnel orientations for multiple ligament reconstructions in the femur. STUDY DESIGN Descriptive laboratory study. METHODS Three-dimensional knee models were developed from computed tomography scans of 21 patients. Medical image processing software was used to create tunnels for each of the primary ligamentous structures, replicating a surgical approach that would be used in multiple ligament reconstructions. Thereafter, the tunnel orientation was varied in surgically relevant directions to determine orientations that minimized the risk of tunnel convergence. The orientation of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) tunnels was held constant throughout the study, while the orientation of the fibular collateral ligament (FCL), popliteus tendon (PLT), superficial medial collateral ligament (sMCL), and posterior oblique ligament (POL) tunnels was varied to avoid convergence. RESULTS A high risk of tunnel convergence was observed between the FCL and ACL tunnels when the FCL tunnel was aimed at 0° in the axial and coronal planes. Aiming the FCL tunnel 35° anteriorly minimized convergence with the ACL tunnel. No tunnel convergence was observed for the PLT tunnel aimed 35° anteriorly and parallel to the FCL tunnel. To avoid convergence between the sMCL and PCL tunnels, the sMCL tunnels should be aimed 40° proximally in the coronal plane and 20° to 40° anteriorly. During concomitant POL reconstruction, the sMCL should be aimed 40° proximally and anteriorly and the POL 20° proximally and anteriorly. The PLT and POL tunnels aimed at 0° in both the coronal and axial planes had an increased risk of violating the intercondylar notch. CONCLUSION Femoral tunnel orientations during multiple ligament reconstructions need to be adjusted to avoid tunnel convergence. On the lateral side, aiming the FCL and PLT tunnels 35° anteriorly eliminated convergence with the ACL tunnel. On the medial side, tunnel convergence was avoided by orienting the sMCL tunnel 40° proximally and anteriorly and the POL tunnel 20° proximally and anteriorly. The POL and PLT tunnels aimed at 0° in the axial plane had an increased risk of violating the intercondylar notch. CLINICAL RELEVANCE The risk of tunnel convergence with the ACL and PCL femoral tunnels can be reduced by adjusting the orientation of the FCL and PLT tunnels and the sMCL and POL tunnels, respectively.

Abstract
PURPOSE Traumatic knee dislocations (KDs) are unusual yet limb-threatening injuries; the timing of surgical intervention is still debated. A systematic review was performed to determine the optimal timing of surgery with respect to injury pattern. METHODS A comprehensive search of Medline, EMBASE, and Cochrane Central Register of Controlled Trials was performed for studies published between 1 January 1974 and 20 April 2014 on the surgical management of "knee dislocation" and "multiligament knee injuries". Surgical timing was classified as acute, chronic, or staged. A systematic review was performed for patients with KD-III according to Schenck's classification using individual patient data. RESULTS Twelve studies including 150 patients (153 knees) with KDs fulfilled the study requirements. Sixty-nine cases with KD-IIIM and 84 cases with KD-IIIL were identified. Excellent or good results were demonstrated in 79.1 % (34 cases) of cases managed with staged treatment versus 58.4 % (45 cases) of cases undergoing acute surgery (p = 0.02), and versus 45.5 % (15 cases) of cases undergoing chronic surgery (p = 0.002). No statistically significant difference was found in the percentage of excellent or good results between the acute and chronic surgery groups (n.s.), or between the KD-IIIM and KD-IIIL groups (n.s.). CONCLUSION Staged treatment yields the best clinical results for patients with KD-III. No statistically significant difference was shown in the clinical results between acute surgery and chronic surgery groups. LEVEL OF EVIDENCE IV.

Abstract
Knee dislocations are catastrophic injuries that demand emergent evaluation and often require a multidisciplinary approach. Long-term outcome studies are relatively scarce secondary to the variability in any given study population and the wide variety of injury patterns between knee dislocations. Multiple controversies exist with regard to outcomes using various treatment methods (early vs late intervention, graft selection, repair vs reconstruction of medial and lateral structures, rehabilitation regimens). Careful clinical evaluation is essential when knee dislocation is suspected.

Abstract
OBJECT
Knee dislocations are often accompanied by stretch injuries to the common peroneal nerve (CPN). A small subset of these injuries also affect the tibial nerve. The mechanism of this combined pattern could be a single longitudinal stretch injury of the CPN extending to the sciatic bifurcation (and tibial division) or separate injuries of both the CPN and tibial nerve, either at the level of the tibiofemoral joint or distally at the soleal sling and fibular neck. The authors reviewed cases involving patients with knee dislocations with CPN and tibial nerve injuries to determine the localization of the combined injury and correlation between degree of MRI appearance and clinical severity of nerve injury.
METHODS
Three groups of cases were reviewed. Group 1 consisted of knee dislocations with clinical evidence of nerve injury (n = 28, including 19 cases of complete CPN injury); Group 2 consisted of knee dislocations without clinical evidence of nerve injury (n = 19); and Group 3 consisted of cases of minor knee trauma but without knee dislocation (n = 14). All patients had an MRI study of the knee performed within 3 months of injury. MRI appearance of tibial and common peroneal nerve injury was scored by 2 independent radiologists in 3 zones (Zone I, sciatic bifurcation; Zone II, knee joint; and Zone III, soleal sling and fibular neck) on a severity scale of 1–4. Injury signal was scored as diffuse or focal for each nerve in each of the 3 zones. A clinical score was also calculated based on Medical Research Council scores for strength in the tibial and peroneal nerve distributions, combined with electrophysiological data, when available, and correlated with the MRI injury score.
RESULTS
Nearly all of the nerve segments visualized in Groups 1 and 2 demonstrated some degree of injury on MRI (95%), compared with 12% of nerve segments in Group 3. MRI nerve injury scores were significantly more severe in Group 1 relative to Group 2 (2.06 vs 1.24, p < 0.001) and Group 2 relative to Group 3 (1.24 vs 0.13, p < 0.001). In both groups of patients with knee dislocations (Groups 1 and 2), the MRI nerve injury score was significantly higher for CPN than tibial nerve (2.72 vs 1.40 for Group 1, p < 0.001; 1.39 vs 1.09 for Group 2, p < 0.05). The clinical injury score had a significantly strong correlation with the MRI injury score for the CPN (r = 0.75, p < 0.001), but not for the tibial nerve (r = 0.07, p = 0.83).
CONCLUSIONS
MRI is highly sensitive in detecting subclinical nerve injury. In knee dislocation, clinical tibial nerve injury is always associated with simultaneous CPN injury, but tibial nerve function is never worse than peroneal nerve function. The point of maximum injury can occur in any of 3 zones.

Abstract
BACKGROUND In the context of acute knee dislocations, suture repair of ruptured cruciate ligaments leads to good clinical results in 80% of cases. Disadvantages are low primary stability and subsequently secondary elongation of the sutured ligaments. In the present study, we compared primary stability of suture repair, reinforced by different suture augments, to cruciate ligament reconstruction. OBJECTIVE The concept of ligament bracing with transosseous suture repair of the cruciate ligaments and additional suture augmentation is biomechanically superior to cruciate ligament reconstruction. MATERIAL AND METHODS A total of 42 porcine knee joints divided into seven groups were examined. The stability of four different suture/augmentation combinations were compared to cruciate ligament reconstruction with human hamstring tendons. The investigational setup consisted of testing 1000 cycles with 20 N to 154 N load in a.-p. translation and 60° flexion. Elongation and load to failure were measured. RESULTS Neither reconstruction (3.13 ± 1.65 mm; 362 ± 51 N) nor augmented suture repair (1.89-2.5 mm; 464-624 N) achieved the primary stability of the intact cruciate ligament (0.63 ± 0.34 mm, 1012 ± 91 N). In comparison to ligament reconstruction, all four augmented suture repairs showed minor elongation in the cyclic test and a higher load to failure. The isolated suture repair showed poor results (6.79 ± 4.86 mm, 177 ± 73 N). CONCLUSION Augmented suture repair provides significantly higher stability compared with isolated suture repair and reconstruction with hamstring tendons. The concept of ligament bracing could be a promising future treatment option in acute knee dislocations. Clinical results remain to be seen.

Abstract
OBJECTIVE Reconstruction of knee stability by primary ligament sutures and additional augmentation after knee dislocation. INDICATIONS Acute knee dislocation Schenck type III and IV. Operative treatment should be performed within 7 days after injury. CONTRAINDICATIONS Chronic instability after knee dislocation, refixable bony avulsions, critical soft tissue, infection, lack of compliance. SURGICAL TECHNIQUE Supine position with electric leg holder. Short arthroscopic assessment of concomitant injuries. Schenck type III medial injuries and Schenck IV injuries: anteromedial parapatellar arthrotomy. Injuries type Schenck III lateral: anteromedian arthrotomy. Armoring of ligament stumps for transosseus sutures. Placement of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) drill tunnels. Extracortical diversion of the suture armorings and insertion of augmentation systems. Fixation of the PCL augmentation in 70-90° flexion. Fixation of the ACL augmentation in 20-30° flexion. Knotting of the transosseus ligament sutures. If necessary (postero-)lateral and/or medial stabilization. POSTOPERATIVE MANAGEMENT Limited weight bearing with 20 kg for 6 weeks. Stabilizing brace (e.g., Hypex-Lite®, Albrecht) generally for 12 weeks. Mobilization under tension of the quadriceps muscle for 6 weeks. RESULTS In total, 20 patients have been treated using the principle of "ligament bracing". So far 8 patients (aged 18-60 years, median 33 years) have been assessed with a follow-up of 10-15 months (median 12 months) postoperatively. In all, 6 patients showed stable knees with good results. Recurrent instability of the ACL was observed in 2 patients; the collateral ligaments and PCL were stable. For the evaluation the following scores were used: IKDC score, Tegner score, and Lysholm score. To objectify the data, stress radiography and physical examination were performed. Using the operative technique mentioned above, no complications occurred. During follow-up 2 patients reported a deficiency of flexion.

Abstract
BACKGROUND Knee dislocations from minor trauma have been reported sparsely in the literature. The consensus is that these injuries tend not to be associated with neurovascular compromise. PURPOSE To present a series of atraumatic knee dislocations in obese and morbidly obese patients and to compare operative versus conservative treatment. STUDY DESIGN Case series; Level of evidence, 4. METHODS This study included 19 patients (21 knees) who presented with knee dislocation from a low-velocity or ultra low-velocity incident. Charts, radiographs, and magnetic resonance images (MRIs) were reviewed, and patients were reviewed based on their latest follow-up. We included patients in our database from 2001 to 2011 and compared knees of patients who had ligament repair or reconstruction (9 total knees) verses nonoperative treatment (12 total knees). Range of motion, activity levels, and knee laxity information were collected as outcome measures to compare operative and nonoperative results. RESULTS The mean age at presentation was 30.3 years (range, 15-74 years), with 5 men and 14 women. The average body mass index (BMI) was 41.4 kg/m(2) (range, 30-64.4 kg/m(2)), with an average follow-up of 31 months (range, 12-72 months). Five patients (27%) had a popliteal artery injury, and 7 (44.4%) had a peroneal nerve injury at presentation. Four had a vascular repair, 1 had an amputation, and 3 of 7 patients had return of peroneal nerve. Ligament reconstruction was performed on 9 individuals. The average operating time for ligament reconstruction was 183% of that with injury-matched normal-weight patients. Eight operative patients who complied with therapy had an average range of motion of 91.4° (range, 60°-110°). The nonoperative patients had an average range of motion of 60.45° (range, 0°-120°). Two of these patients later required a total knee arthroplasty (3 total knee arthroplasties overall). CONCLUSION Knee dislocations from minor falls occur in obese patients and are often accompanied by neurovascular complications. While surgical reconstruction is more time consuming and more difficult than that in normal-weight individuals, it may be preferable to nonoperative treatment.

Abstract
Multiligamentous knee injuries are rare but serious injuries that can threaten limb viability. As such, they require careful management to give patients the best chance of immediate and ultimate functional recovery. However, as these injuries are rare, there is paucity in prospective comparative studies large enough to provide high level evidence for best practice. This lack of comprehensive and convincing evidence has made the management of multiligamentous knee injuries an area of active debate and controversy. The debate on whether surgical management leads to better outcomes than non-operative management, the optimal timing of surgery after injury and whether repair is better than reconstruction is still ongoing. Using the Oxford Levels of Evidence, this review summarises the latest high level evidence to provide answers to these issues. Recommendations for practice have also been offered and assigned a grade using a published scale.

Abstract
Objective The aim of the study was to: 1) evaluate the differences in pre-post operative knee functioning, mechanical stability, isokinetic knee muscle strength in simultaneous arthroscopic patients after having undergone an anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) with hamstring tendons reconstruction, 2) compare the results of ACL/PCL patients with the control group. Design Controlled Laboratory Study. Materials and Methods Results of 11 ACL/PCL patients had been matched with 22 uninjured control participants (CP). Prior to surgery, and minimum 2 years after it, functional assessment (Lysholm and IKDC 2000), mechanical knee joint stability evaluation (Lachman and “drawer” test) and isokinetic tests (bilateral knee muscle examination) had been performed. Different rehabilitation exercises had been used: isometric, passive exercises, exercises increasing the range of motion and proprioception, strength exercises and specific functional exercises. Results After arthroscopy no significant differences had been found between the injured and uninjured leg in all isokinetic parameters in ACL/PCL patients. However, ACL/PCL patients had still shown significantly lower values of strength in relative isokinetic knee flexors (p = 0.0065) and extensors (p = 0.0171) compared to the CP. There were no differences between groups regarding absolute isokinetic strength and flexors/extensors ratio. There was statistically significant progress in IKDC 2000 (p = 0.0044) and Lysholm (p = 0.0044) scales prior to (44 and 60 points respectively) and after the reconstruction (61 for IKDC 2000 and 94 points for Lysholm). Conclusions Although harvesting tendons of semitendinosus and/or gracilis from the healthy extremity diminishes muscle strength of knee flexors in comparison to the CP, flexor strength had improved. Statistically significant improvement of the knee extensor function may indicate that the recreation of joint mechanical stability is required for restoring normal muscle strength. Without restoring normal muscle function and strength, surgical intervention alone may not be sufficient enough to ensure expected improvement of the articular function.

Abstract
Objective Describe the ligamentous and associated injuries that occur in the traumatic knee dislocation, relating them to the mechanisms of trauma and to identify patterns of injuries. Methods Twenty three knee dislocations were described in the period between March 2010 and March 2011. After the diagnosis of the lesions, the reduction and transarticular external fixation of the dislocated knees were done. At the second moment, the patients were evaluated with physical examination under anesthesia and the surgical exploration of peripheral lesions was perfomed by a surgeon of the knee surgery group of this institution. The patients data with the description of the injuries were found and registered. Results 65% of patients were male, the average age was 35 years and the most common mechanism of trauma was the motorcycle accident (60%). The lesion of the anterior cruciate ligament (ACL) occurred in 75% of the cases, and the lesion of posterior cruciate ligament (PCL) in 95%. The medial peripheral injuries happened in 65% of the dislocations, and the lateral lesions in 40%. The most common dislocations were classified as KDI (25%) and as KDIIIm (25%). The arterial injury was present in 15% of the cases, and the nervous injury where registered in one patient (5%). At the initial radiographic evaluation, 45% of the dislocations presented reduced. Conclusion The characteristics of the knee dislocations described showed a great range of variability demonstrating that an individualized evaluation of each case is mandatory. The surgeon should be able to recognize and choose the correct treatment to these lesions.

Abstract
Complex ligament injuries can compromise a knee joint and residual conditions comprise stiffness (arthrofibrosis), instability, cartilage damage leading to osteoarthritis and bone deformity. Accurate diagnosis must address the direction and extent of the instability, the severity of any cartilage lesion and an analysis of the axis and bone deformity as well as important cofactors. Therapeutic options are adhesiolysis, ligament reconstruction, cartilage regeneration and axis correction. As a consequence patients mostly profit from the procedure but there is never a return to the functional level that existed before injury.

Abstract
PURPOSE Treatment of knee dislocation is still controversial. There is no evidence to favour ligament suture or reconstruction. Until now, no meta-analyses have examined suture versus reconstruction of cruciate ligaments in knee dislocations with respect to injury pattern and rupture classification. METHODS We searched Medline, the Cochrane Controlled Trial Database, and EMBASE for studies on surgical treatment for 'knee dislocation' and 'multiple ligament injured knee'. A meta-analysis was performed using individual patient data. RESULTS Nine studies including 195 patients (200 knees) with a mean age of 31.4 (±13) years fulfilled the study requirements. Thirteen cases of type II dislocations, 63 cases of type III medial, 84 cases of type III lateral, and 40 cases of type IV dislocations, according to Schenck's classification, were found. Poor or moderate results were found in 70 % of patients without surgical treatment of ACL or PCL (n = 27). Patients (n = 40) treated by sutures of the ACL and PCL demonstrated a significantly greater proportion of excellent or good results (40 and 37.5 %, respectively) (p < 0.001). Patients who underwent reconstruction of the ACL and PCL (n = 75) showed excellent or good results (28 and 45 %, respectively). No significant difference was found when comparing suture versus reconstruction of the ACL and PCL (n.s.). The outcome depends considerably on Schenck's injury pattern classification. CONCLUSION Conservative treatment after knee dislocation yields poor clinical results. Suture repair of cruciate ligaments can still serve as an alternative option for multiligament injuries of the knee and achieve good clinical results, which are comparable to those of ligament reconstruction. The data provided by this meta-analysis should be reinforced by a prospective study, in which suture repair and ligament reconstruction are compared. LEVEL OF EVIDENCE IV.

Abstract
OBJECTIVE The purpose of the study was to report our early outcome in the management of multiligament knee injuries with the ligament advanced reinforcement system (LARS). SUBJECTS AND METHODS Between 2007 and 2010, 9 of 11 patients operated on for multiligament knee injuries were included in this study; 2 patients were excluded due to complicated neurovascular injuries, open knee dislocations and severe comorbidities. All patients were managed acutely (<3 weeks) by reconstructions of the cruciate and collateral ligaments with LARS ligament and were followed up for an average of 30 months (18-46 months). RESULTS The mean Lysholm score of the 9 patients at final follow-up was around 90 (range 88-94) with an average Tegner activity score of 5.5. The postoperative function of 1 case of KD-11 and 2 cases of KD-111 was rated as 'A,' while the remaining cases were rated 'B'. At final follow-up, minor osteoarthritic degeneration was detected in 1 case of KD-III and 2 cases of KD-IV. Superficial infection developed in 1 case, and no cases of knee synovitis and premature osteoarthritis were recorded. CONCLUSION A creditable outcome at mean of 30 months' follow-up was obtained in acute single-stage reconstruction of uncomplicated multiligament knee injuries with LARS ligament.

Abstract
An acute knee dislocation is an uncommon injury, with a high rate of associated vascular and neurologic injuries as well as potentially limb-threatening complications. High-energy trauma is the most common cause of an acute knee dislocation, although lower-energy injuries, such as those sustained during athletic competition, are increasing in incidence. Injuries to the popliteal artery and common peroneal nerve are relatively common, requiring a high index of suspicion and complete neurovascular examination in a timely fashion. All cases of suspected knee dislocation should have an ankle-brachial index performed, reserving arteriography for those with an abnormal finding. Initial management consists of closed reduction, if possible, and application of a hinged brace or external fixator. Definitive management remains an area of controversy, although anatomic surgical repair or reconstruction is favored by most surgeons to help optimize knee function. Most patients treated for a knee dislocation can expect to return to their daily activities, but with less predictable returns to sporting activities.

Abstract
Knee dislocations are rare and often associated with damage to the surrounding structures. We present a case where a soldier sustained a complex knee dislocation during routine training. This trauma was associated with a compartment syndrome, occlusion of the popliteal artery, lesion of the peroneal nerve and multiple lesions of ligaments and tendons of the knee.

Abstract
BACKGROUND Traumatic knee dislocations that result in multiple-ligament knee injuries are unusual and are poorly studied. We are not aware of any prospective data regarding their treatment. Both the optimum timing of surgery for repair or reconstruction and the aggressiveness of rehabilitation are debated. The purpose of this systematic review was to compare the outcomes of early, delayed, and staged procedures as well as the subsequent rehabilitation protocols. METHODS We surveyed the literature and retrieved twenty-four retrospective studies, involving 396 knees, dealing with the surgical treatment of the most severe multiple-ligament knee injuries (those involving both cruciate ligaments and either or both collateral ligaments). Data were extracted, and surgical timing was categorized as acute, chronic, or staged. Early postoperative mobility and immobilization were also compared. RESULTS We found that acute treatment was associated with residual anterior knee instability when compared with chronic treatment (odds ratio, 2.58; 95% confidence interval, 1.2 to 5.8; p = 0.018). Significantly more patients who were managed acutely were found to have more flexion deficits when compared with those who were managed chronically (odds ratio, 5.18; 95% confidence interval, 1.5 to 17.5; p = 0.004). Staged treatments yielded the highest percentage of excellent and good subjective outcomes (79%; 95% confidence interval, 62.2% to 89.3%). Additional treatment for joint stiffness was significantly more likely in association with acute treatment (17%; 95% confidence interval, 13.0% to 22.4%; p < 0.001) and staged treatment (15%; 95% confidence interval, 7.6% to 28.2%; p = 0.001) when each was compared with chronic treatment (0% [zero of seventy-one]; 95% confidence interval, 0.0% to 5.1%). Early mobility was not associated with increased joint instability in acutely managed patients. Early mobility yielded fewer range-of-motion deficits but did not reduce the rate of follow-up manipulation or arthrolysis. CONCLUSIONS This review of the available literature suggests that delayed reconstructions of severe multiple-ligament knee injuries could potentially yield equivalent outcomes in terms of stability when compared with acute surgery. However, in the acutely managed patient, early mobility is associated with better outcomes in comparison with immobilization. Acute surgery is highly associated with range-of-motion deficits. Staged procedures may produce better subjective outcomes and a lower number of range-of-motion deficits but are still likely to require additional treatment for joint stiffness. More aggressive rehabilitation may prevent this from occurring in multiple-ligament knee injuries that are treated acutely.
