“…This is primarily because its low incidence makes it inherently difficult to evaluate treatments with large, prospective clinical trials. Recent evidence suggests an incidence of 0.072 events per 100 patient-years [2]. Although this is substantially higher than the previously reported incidence of 0.001 events per 100 patient-years in the general population and 0.0125 events per 100 patient-years within orthopaedic injuries, it is still very low [14,18].…”

“…Although this is substantially higher than the previously reported incidence of 0.001 events per 100 patient-years in the general population and 0.0125 events per 100 patient-years within orthopaedic injuries, it is still very low [14,18]. Because multiligament injuries often reduce spontaneously, the actual incidence may be slightly higher as a result of missed diagnoses [1][2][3][4]9]. The low incidence of this injury also presents barriers to epidemiologic investigation [3].…”

“…Because the mechanism of injury is often associated with high-energy trauma or sports, it is not surprising that this patient population is relatively young. Indeed, case series have established young athletes as a common patient population and there is evidence of an inverse relationship between patient age and risk for injury [2,3]. The data demonstrated that males were more likely to undergo multiligament reconstruction, as 72% of the population was male.…”

“…The mean patient age in our sample was 32 years. The mean age typically reported in the literature for patients with multiligament knee injuries is between 29 and 37 years [2,22,26]. Because the mechanism of injury is often associated with high-energy trauma or sports, it is not surprising that this patient population is relatively young.…”

“…As a result, the epidemiologic profile of multiligament knee injuries remains conspicuously incomplete. A recent study on the demographics of knee dislocations, the first population-based study on the topic in more than five decades, has provided essential data on the incidence of this injury [2]. However, to our knowledge, there still are no population-based data on the outcomes of multiligament knee reconstruction.…”

Background The multiple-ligament-injured knee represents a special challenge, being an uncommon injury that is both severe and complicated to treat. Many studies have evaluated patients treated for this injury, but most are limited in their scope. The evaluation of this injury and its treatment using an administrative database might provide a different perspective.Questions/purposes Using a large administrative database, we determined (1) the number of multiligament knee reconstructions in New York State, (2) the rate of 90-day hospital readmission, and (3) the frequency of subsequent knee surgery. We examined the rates of these outcomes as a function of diagnosis, admission type, discharge status, comorbidity burden, and patient demographic factors. Methods We used the New York Department of Health Statewide Planning and Research Cooperative System (SPARCS), a database with information on patient characteristics, diagnoses, and treatments, to identify patients who underwent a multiligament procedure in a nonfederal facility from 1997 to 2005 using ICD-9-CM and Current Procedural Terminology codes. SPARCS collects data from all nonfederal acute care facilities, with an estimated reporting completeness of almost 99% for the years in this study. We evaluated data on patient age, sex, admission type, discharge status, and comorbidity burden (using Elixhauser comorbidities) and developed a multivariable logistic regression model to assess the influence of confounding variables. Results We identified 1032 patients in this database who underwent multiligament knee reconstruction in New York State from 1997 to 2005. The frequency of readmission within 90 days was 4.8% (n = 49). Readmission was more likely for patients who underwent inpatient multiligament reconstruction (odds ratio [OR] = 2.3; 95% CI: 1.2-4.4; p = 0.014), had a diagnosis of dislocation (OR = 2.2; 95% CI: 1.2-3.9; p = 0.011), or had various Elixhauser comorbidities, including chronic lung disease (OR = 6.4; 95% CI: 1.5-27.2; p = 0.013), fluid and electrolyte disorders (OR = 19.7; 95% CI: 2.5-155.7; p = 0.005), and anemia deficiency (OR = 5.6; 95% CI: 1.05-29.4; p = 0.044). Two hundred eighty-seven patients (28%) underwent subsequent knee surgery between their index

PurposeThis study investigates the clinical and activity‐based outcomes after anterior cruciate ligament reconstruction (ACLR) versus multiligamentous knee reconstruction (MLKR) following a pivoting sports injury.MethodsFifty MLKR patients were included, of which 20 (40%) were injured during pivoting sports. A further 50 patients undergoing ACLR following an injury during pivoting sports were consecutively recruited for comparison. Patients were assessed before the surgery and at 6‐, 12‐ and 24 months with patient‐reported outcome measures (PROMs) including the International Knee Documentation Committee (IKDC) form, Tegner activity scale (TAS) and anterior cruciate ligament return to sport after injury (ACL‐RSI) score. Knee movement, the single (SHD) and triple (THD) hop tests for distance, and peak isokinetic knee extensor and flexor strength were assessed, with Limb Symmetry Indices (LSIs) calculated. Outcomes were compared across groups: (1) ACLR (n = 50), (2) MLKR (n = 50) and (3) MLKR due to pivoting sport injury (n = 20).ResultsIKDC, TAS and ACL‐RSI scores remained lower (p < 0.05) in the full MLKR versus ACLR cohort at all timepoints. Comparing the ACLR and MLKR cohort that had injuries specifically during pivoting sports, the IKDC (p < 0.001) and TAS (p = 0.009) were higher in the ACLR group at 6 months, and the ACL‐RSI was higher at 6 (p < 0.001) and 12 (p = 0.007) months, there were no further differences. Hop and knee extensor strength LSIs were lower (p < 0.05) in the full MLKR (versus ACLR) cohort at all timepoints (apart from the 24‐month SHD LSI). However, the ACLR group only demonstrated greater LSIs than the pivoting sport MLKR for the SHD at 6 months (p < 0.001), and knee extensor strength at 6 (p < 0.001) and 12 (p < 0.001) months.ConclusionsWhile the recovery of patients undergoing MLKR due to a pivoting sports injury is delayed compared with their ACLR counterparts, the clinical outcome and activity profile are similar by 24 months.Level of EvidenceLevel IV.

PurposeKnee joint dislocations, though rare, present significant challenges due to potential complications like vascular and nerve damage, and are known to be often linked to sports injuries, accidents and obesity. This study aims to analyse the epidemiology, incidence and treatment approaches for knee dislocations in Germany from 2019 to 2022.MethodsThis retrospective cohort study utilized data from the German Institute for the Hospital Remuneration System to examine knee dislocation cases across German medical institutions. Patient data coded under International Statistical Classification of Diseases and Related Health Problems 10 for ‘knee dislocation’ enabled detailed analysis by age, sex and surgical procedures categorized by operation and procedure codes. The Patient Clinical Complexity Level (PCCL) assessed complication severity.ResultsAnalysis of 1643 knee dislocation cases revealed an incidence rate of 0.44–0.54 per 100,000 inhabitants annually. During the years 2020 and 2021, there were fewer cases of knee dislocations. Male patients comprised 50%–56% of cases, with an average hospital stay of 11 days. Most cases were PCCL 0 (62%–72%) and predominantly affected patients aged 18–29 years. Anterior tibial dislocations were common among classified cases. Injuries included ligament ruptures, meniscus lesions and grade I soft‐tissue injuries. Patients with pre‐existing knee prostheses constituted 0%–16% annually. Treatment involved closed reduction, external fixation and surgeries like capsuloligamentous reconstructions and arthroscopic procedures. Revision knee arthroplasty was required in 2%–9% of cases, with obesity rates up to 7%.ConclusionsThis study provides valuable insights into the epidemiology, incidence and treatment of knee dislocations in Germany, with a focus on demographic risk factors, treatment complexities and the impact of obesity and knee prostheses. The findings emphasize the importance of specialized care in larger hospitals, comprehensive management of concomitant injuries and the need for improved coding accuracy. Future research should aim to refine treatment protocols.Level of EvidenceLevel III.
