Effect of Patient Resilience on Functional Outcomes After Anterior Cruciate Ligament Reconstruction.

Previous studies have examined the relationship between patient resilience and functional outcome scores after anterior cruciate ligament reconstruction (ACLR). However, past studies have failed to explore the longitudinal relationship between preoperative resilience and functional outcomes 2 years after ACLR. To evaluate the relationship between preoperative patient resilience and functional outcomes 2 years after ACLR. Cohort study; Level of evidence, 3. Patients were identified who underwent ACLR for anterior cruciate ligament tears between January and June 2020 at a single institution. Those who completed the Brief Resilience Scale preoperatively as part of routine patient questionnaires were considered for inclusion. Patients were contacted a minimum of 2 years after ACLR to complete the short form of the Knee injury and Osteoarthritis Outcome Score (KOOS-JR), Single Assessment Numeric Evaluation (SANE), International Knee Documentation Committee (IKDC) Subjective Knee Form, and visual analog scale (VAS). Outcomes were compared among patients with low resilience (LR), normal resilience (NR), and high resilience (HR), as defined in a previous study.23. A total of 81 patients were included in the final analysis, with 14 patients in the low preoperative resilience group, 54 in normal, and 13 in high. The mean age of the cohort was 32.0 years, and there were no significant differences in age, sex, race, graft type, or psychiatric comorbidities among the resilience groups. Significantly increased postoperative KOOS-JR scores were observed in patients in the HR group as compared with those in the NR and LR groups (94.8, 86.7, and 79.6, respectively; P = .031). There were also significantly increased postoperative SANE scores in patients in the HR group versus those in the NR and LR groups (92.3, 83.5, and 69.2; P = .012). Patients with high preoperative resilience achieved the IKDC Patient Acceptable Symptom State at significantly higher rates (P = .003). No significant differences were observed in postoperative VAS (P = .364), IKDC (P = .072), or change in IKDC (P = .448) over time among resilience groups. Postoperatively, 30 patients (37.0%) changed resilience groups, with 13 moving down and 17 moving up in category (low, n = 12; normal, n = 55; high, n = 14). Preoperative resilience correlated with KOOS-JR and SANE scores 2 years after ACLR but did not correlate with VAS, IKDC, or change in IKDC over the same period. Resilience was not static, with changes in resilience observed from initial to final evaluations. Resilience is not a strong predictor of postoperative patient-reported outcomes after ACLR.

Experimental Assessment between Dissimilar Techniques and Methodologies to Sports Knee Injury using Magnetic Resonance Imaging

The anterior cruciate ligaments, which are crucial for conserving the normal biomechanics of human being knees, are the majority commonly injured knee-ligaments. An anterior cruciate ligament injury is originated by a split or wrench of the anterior cruciate ligaments, which are imperative ligaments in the knee. ACL injure is mainly and frequently caused by sports like football, soccer, and the like that require quick pauses or direction changes, jumping, and landings. These days, the area of diagnostics heavily relies on magnetic resonance imaging. It is effective in determining the presence of meniscal tears and damage to the cruciate ligament. This study's primary objective is to use magnetic resonance imaging knee images to find anterior cruciate ligament tears, which can be useful in identifying issues with the knee. Inception-v3, an established deep transfer learning (DTL) model based on a DCNN was used in this study to classify anterior cruciate ligament tears in MRI scans. Classification, Preprocessing, and feature extraction are the major processes used in the current study executions. The dataset type utilized in this article of research study was built using the MRNet database. Seventy percent of the data set is used for preparation and testing, while the lingering thirty percent is utilized for performance analysis in this comparison model. The future augmented methodology can improve upon the present models' performance through the application of DL and ML techniques.

A Comparative study of anterior cruciate ligament repair effectiveness in proximal ACL tears

Background. Anterior cruciate ligament (ACL) reconstruction is a gold standard surgical option for ACL tears. Another go-to method is primary ACL repair. The latter has its own limitations such as small range of indications – proximal tears only, which constitute a significant portion of ACL injuries. Although the primary repair has been known for a long time and is still developing, recent publications show conflicting outcomes. Aim of study was to compare functional outcomes of patients with ACL reconstruction and primary repair. Methods. During 2020-2023 we conducted randomized prospective multicenter control comparative study which included 170 patients with ACL tear types A, B, E according to Gächter classification, with injuries no older than 3 months. Patients were divided into two groups: 1st group – primary repair of ACL, 2nd group – ACL reconstruction. Knee function was assessed before surgery and 3, 6, 12, 24 months after the treatment using the IKDC 2000 and Lyshlom Knee Score. Results. Type E ACL injury prevailed in the sample. The most common associated injury in both cohorts was medial meniscus tear (39,3±0,05% and 45,3±0,05%). 15,5±0,04% patients with primary repair had chondrolabral defects, reconstruction group – 10,5±0,03%. 46,03±0,06% of 2nd and 25,35±0,05% of 1st group (p0,05) received pain relief therapy in the form of opioid analgesics. The proportion of patients requiring reoperation for ACL injury in 1st group was 3,5%, in 2nd group – 1,2%. Both groups had a statistically significant increase in functional outcomes at 3, 6, 12 months (p0,05). The difference of knee function between groups was not statistically significant (p0,05). Conclusion. Primary ACL repair still retains a large number of limitations: it cannot and should not replace ACL reconstruction, but should be used with strict adherence to the indications and surgical technique to show comparable functional outcomes.

Enhancing stability and outcomes in young Indian footballers: The synergistic effect of anterior cruciate ligament reconstruction with lateral extra-articular tenodesis – A prospective observational cohort study

Objectives: Anterior cruciate ligament (ACL) tears are frequently seen injuries in young footballers that can contribute to chronic knee instability, meniscal injuries, and increased risk of early-onset osteoarthritis if not properly treated. Materials and Methods: This study evaluated the clinical findings of combined ACL reconstruction and lateral extra-articular tenodesis (LET) in 22 male footballers aged 20–30. ACL reconstruction was carried out using hamstring autografts and LET was done utilizing a modified Lemaire procedure with iliotibial band autograft. Clinical findings were studied preoperatively and at six months and one year postoperatively utilizing the International Knee Documentation Committee (IKDC) and Tegner–Lysholm scores. Results: Mean IKDC and Tegner-Lysholm scores were similar or slightly improved at six months compared to pre-operative baselines and further increased at one year follow-up, with the improvements being statistically significant. There are no cases of graft failure occurred. Conclusion: A combination of ACL reconstruction and LET is a safe and effective treatment for ACL tears in young footballers, which can restore knee stability and allow them to go back to sports. Adding LET to ACL reconstruction may help lower the likelihood of graft failure in this high-risk population.

Epidemiology of paediatric winter sports-related injuries in France: The WINTRAUMA-1 retrospective cohort study.

To describe the epidemiology of injuries related to winter sports in patients younger than 15 years in France. We conducted a retrospective observational multicentre cohort study of patients younger than 15 years who were seen by mountain-community general practitioners for winter-sports injuries in 1999-2022. Of the 108 619 patients (mean age, 11.4 ± 2.8 years), 76 724 (70.6%), 26 186 (24.1%) and 2132 (2.0%) were injured while skiing, snowboarding and sledding, respectively. Helmet use was noted in 50 164 (46.2%) patients and increased over time but remained low among sledders. A collision was the mechanism in 12.3% of patients overall and 32.1% of sledders. The most common injuries overall were wrist fractures (48.5%), head and trunk injuries (42.3%), and anterior cruciate ligament (ACL) tears (23.7%), with wrist fractures being more common in beginners (24.7%) and head/trunk injuries and ACL tears in advanced participants (18.3% and 2.6%, respectively). Only 3699 (3.4%) patients were admitted after the general-practitioner visit, notably for leg or ankle fractures (9.5%). Winter sports-related injuries vary according to age, sex, skill level and sport. Admission rates are low but might be further decreased by better prevention. Protective measures should be tailored to each sport and individual.

Prescription Testosterone is Associated with an Increased Risk of Anterior Cruciate Ligament Injury

To characterize the relationship between testosterone replacement therapy (TRT) and anterior cruciate ligament (ACL) injuries. A retrospective cohort study using a large insurance database was conducted. Patients who were prescribed TRT for at least 3 months were matched with controls who were not prescribed TRT. Rates of ACL tears were compared between the cohorts. Multiple subgroups were created based on age (<25 years, 25-35, 36-45, 46-55, 56-65, and 65+). Multivariable logistic regressions were performed to determine the association of TRT with ACL tears while accounting for demographic variables and comorbidities. After matching, there were 160,839 patients in both the TRT cohort and control cohort. The incidence of ACL injuries was 17.8 per 10,000 person-years (95% CI: 16.4-19.2) for patients who were prescribed TRT and 4.9 per 10,000 person-years (95% CI: 4.1-5.7) for controls (p<0.001). Within 2 years of filling a testosterone prescription for at least 3 months, 572 (0.35%) patients experienced an ACL injury compared to only 157 (0.10%) controls during the same follow-up period (OR: 2.77; 95% CI: 2.26-3.42, p<0.001). When stratified by age, all groups except the <25 years of age group demonstrated significantly higher rate of ACL tears (OR 3.91-12.3, p<0.001-0.009). When separated by sex, males on TRT were 3.13 (95% CI: 2.50-3.93, p<0.001) times more likely while females on TRT were 1.94 (95% CI: 1.13-3.41, p=0.018) times more likely to experience an ACL injury compared to controls. This study found that patients prescribed at least three months of TRT had a significantly higher incidence of ACL injuries compared to controls within a two-year follow-up period. Level III, retrospective comparative study.

Functional outcome after arthroscopic mosaicplasty for localised osteochondral defects in the knee

Background: Knee injuries are commonly encountered in active sports persons as well as nonathletes, with approximately 60% of patients having cartilage damage with or without associated ligament and meniscal injuries. In this study, we report on the functional outcome of autologous osteochondral grafting in localised cartilage lesions of the knee. MethodsA longitudinal follow-up study was conducted on 50 patients aged between 18-55 years with symptomatic focal cartilage defect in the knee of size less than 2.0 cm2 after necessary inclusion/exclusion criteria. Management involved arthroscopic autologous osteochondral grafting. The donor cartilage was from the non–weight-bearing region of the ipsilateral knee. Other associated intra-articular injuries were addressed in the same sitting. The patients were followed up after 6 weeks, 3 months and 6 months and clinical status documented by the Lysholm Knee Function Scale (LKFS). ResultsMost patients were young active males. Clinical presentation involved pain in all participants, followed by joint line tenderness. There was at least one associated injury to other intra-articular structures in 52% of the patients. The commonest associated injury was anterior cruciate ligament (ACL) tear followed by meniscus tear. The mean size of the focal cartilage defect was 1.013 cm2, ranging from 0.8 cm2 to 1.6 cm2. The mean preoperative LKFS was 56.97 ± 1.38 (standard error). There was a statistically (p < 0.001) as well as clinically significant (clinically important difference >13.0 and patient acceptable symptomatic state >70.0) improvement in the mean Lysholm score, which was 70 ± 1.32, 81.3 ± 1.12 and 92.1 ± 1.11 at the end of 6 weeks, 3 months and 6 months respectively. Eighty-four percent of the patients showed excellent functional outcome at 6 months (LKFS >90), whereas 8% and 4% had good and fair outcomes, respectively, at 6 months (LKFS: 70–90). Two patients (4%) who had failed ACL reconstruction had poor outcome (LKFS <70)at 6 months. ConclusionMosaicplasty is an excellent procedure for managing cartilage defects of small to medium sizes, less than 2.0 cm2. The short-term results are satisfying and can accelerate rehabilitation of sports injuries. It is noteworthy that instability is a contra-indication for the procedure to succeed.

Changes in the Elongation Pattern of the Medial Collateral Ligament During a Single-Leg Squat After Anterior Cruciate Ligament Reconstruction.

An anterior cruciate ligament (ACL) tear impairs knee biomechanics in daily activities and potentially breaks the synergy among other knee ligaments. Previous studies have demonstrated that the biomechanics of collateral ligaments is influenced by ACL deficiency. To investigate changes in the elongation patterns of the medial collateral ligament (MCL), lateral collateral ligament (LCL), and posterior cruciate ligament (PCL) during the execution of a single-leg squat before and after ACL reconstruction. Descriptive laboratory study. A total of 16 patients (mean age, 24.9 ± 8.5 years) with ACL deficiency were enrolled in the study. Magnetic resonance imaging scans of the affected knees were used to produce 3-dimensional models of the tibia and femur and identify insertion sites of the MCL, LCL, and PCL. Motion capture of a single-leg squat was performed through a biplanar radiographic system. Data were acquired before ACL reconstruction and at a minimum of 18 months (mean, 22.9 ± 4.1 months) postoperatively. The centroids of the ligaments' insertions were used to calculate the length of the investigated structures during the squat task. Absolute length (L), absolute length increase from the orthostatic resting position (ΔL), and relative length increase (ΔL%) were computed for each ligament, and preoperative and postoperative data were compared using the paired Student t test. The intraclass correlation coefficient was used to determine the reliability of the ligament insertion's identification and kinematics between 2 independent observers. Significant differences were found for the MCL in absolute length increase (P = .047; Cohen d = 0.60) and relative length increase (P = .043; Cohen d = 0.61) from rest between preoperatively and postoperatively (ΔL pre = 1.0 mm; ΔL post = -1.1 mm; difference = 2.1 mm) at 0° to 30° of knee flexion during the descending phase of the single-leg squat. No differences were seen in the elongation patterns of the LCL or PCL from before to after ACL reconstruction. The MCL was significantly longer between 0° and 30° in ACL-deficient knees compared with ACL-reconstructed knees during the descending phase of a single-leg squat. No differences were identified for the LCL or PCL. Early ACL reconstruction could have a protective effect on the MCL in combined ACL and MCL lesions.

Influence of Injury to the Kaplan Fibers and Anterolateral Ligament on Pivot-Shift Phenomenon in Adult and Adolescent Patients With Anterior Cruciate Ligament Injury: A Retrospective Cohort Study.

Studies have shown that Kaplan fibers (KFs) play a role in controlling anterolateral rotatory knee laxity in anterior cruciate ligament (ACL) injury. However, recent clinical studies have suggested that KF injuries are not associated with a higher-grade pivot shift in knees with acute ACL injuries. To compare the effect of KF and anterolateral ligament injury on anterolateral rotatory laxity as measured by the pivot-shift test in both adult and adolescent patients with acute ACL injury. Cross-sectional study; Level of evidence, 3. This study consisted of patients who experienced primary acute ACL tears between January 2019 and December 2021. The magnetic resonance imaging examinations and pivot-shift tests for these individuals were conducted within 14 days after injury. Variables associated with concomitant injury were included in a binary logistic regression model to evaluate risk factors of a high-grade pivot shift and a KF injury. The study included 540 patients with acute ACL tears (64 adolescent patients and 476 adults). The main risk factor for a high-grade pivot shift after acute ACL injury in adults was partial or total disruption of anterolateral ligament continuity (odds ratio [OR], 2.271; 95% CI, 1.499-3.442). In adolescent patients, the main risk factor was KF injury (OR, 19.98; 95% CI, 2.367-168.669), including edema and disruption of continuity. The main risk factor for a high-grade pivot shift after acute ACL injury differs between adolescent patients and adults: the KF injury sign in adolescent patients indicates a higher-grade pivot shift.

The Relationship Between Exogenous Testosterone Use and Risk for Primary Anterior Cruciate Ligament Rupture

Background: In the United States, testosterone therapy has markedly increased in recent years. Currently, there is a paucity of evidence evaluating the risk of ligamentous injuries in patients taking testosterone replacement therapy (TRT). Purpose/Hypothesis: The purpose of this study was to quantify the association between TRT and the incidence of anterior cruciate ligament (ACL) injuries and the subsequent risk of ACL reconstruction (ACLR) failure. It was hypothesized that individuals receiving TRT would demonstrate an increased risk for index ACL injury and ACL rerupture. Study Design: Cohort study; Level of evidence, 3. Methods: This is a retrospective cohort study utilizing the PearlDiver database. Records were queried between 2011 and 2020 for patients aged 18 to 59 years who filled a testosterone prescription. A matched control group based on age, sex, Charlson Comorbidity Index, tobacco use, diabetes, and hypothyroidism consisted of patients aged 18 to 59 years who had never filled a prescription for exogenous testosterone. International Classification of Diseases, 9th and 10th Revisions and Current Procedural Terminology (CPT) codes were utilized to identify patients with ACL injuries and those undergoing reconstruction. Multivariable logistic regression was used to compare rates of ACL injury at 6 months, 1 year, and 2 years after initiating TRT. ACLR failure was also examined at 1-year intervals for 5 years for individuals filling a TRT prescription. Results: A total of 851,816 patients were enrolled, with 425,908 patients in the TRT and control groups, respectively. The TRT cohort was significantly more likely to experience an ACL tear during 6-month (OR, 2.66; 95% CI, 2.17-3.26), 1-year (OR, 2.46; 95% CI, 2.11-2.86), and 2-year (OR, 2.22; 95% CI, 1.98-2.48) periods. The rate of reconstruction failure did not differ between the 2 cohorts at up to 5 years of follow-up ( P &gt; .05). Conclusion: Patients receiving TRT were significantly more likely to sustain a primary ACL rupture but were not at a statistically significant increased risk of reconstruction failure.

Evaluating the Importance of Return to Sports and Hamstring Strength in a Discrete Choice Experiment for Anterior Cruciate Ligament Injury.

With emerging treatments for anterior cruciate ligament (ACL) injury, analysis of patient preferences is lacking to align clinical care and research with patient priorities. To identify patient priorities for outcomes after surgical intervention if they were to sustain an ACL tear, analyze what outcome measures influenced preferences, and determine whether patient demographics influenced preferences. Cross-sectional study. The authors screened patients aged 18 to 30 years who presented for upper extremity complaints to a single institution in 2023. Patients were excluded for current lower extremity injury or history of a knee injury requiring surgical consultation. The authors designed a discrete choice experiment through literature review of outcome measures for bridge-enhanced ACL restoration (BEAR) and ACL reconstruction (ACLR) with hamstring tendon autograft. Measures included return to sports, risk of arthritis, risk of reinjury, and hamstring strength. Patients chose surgery A (ACLR with hamstring tendon autograft) or surgery B (BEAR) and then rated the importance of each outcome measure on their selection. In total, 100 participants (36 female; mean age, 25.1 ± 4.0 years) completed the discrete choice experiment. Overall, 56.0% participated in sports and 80.0% were employed. Based on surgery choice group, there were no significant differences in sex, age, Marx Activity Scale score, sports participation, or employment status between patients who selected BEAR or ACLR with hamstring tendon autograft (all P > .361). Return to sports and hamstring strength were significant priorities for patients in procedure selection (P ≤ .011). Of the patients who selected ACLR with hamstring tendon autograft, 31.6% would not elect to undergo this procedure. In this discrete choice experiment of adults without prior ACL injury, return to sports and hamstring strength were identified as patient priorities when selecting a procedure for ACL injury. Risk of reinjury, however, was not a significant factor in procedure selection. Importantly, these priorities were maintained regardless of patient characteristics, activity level, or employment status.

Arthroscopic meniscus transplant using autologous semitendinosus with bone marrow aspirate-derived fibrin clot along with anterior cruciate ligament reconstruction – A case report

Subtotal and total meniscectomy is known to advance osteoarthritis in patients. Meniscus transplant using semitendinosus autograft is a viable option in young patients. We have presented the early follow-up, along with technical video, for arthroscopic meniscus transplant with autologous semitendinosus graft with bone marrow aspirate-derived fibrin clot along with anterior cruciate ligament (ACL) reconstruction, in the primary surgery, in a patient of ACL tear along with near-complete loss of medial meniscus due to auto-meniscectomy. The patient showed good functional and radiological outcome at 9 months.

The Impact of Anterior Cruciate Ligament Tear on Player Performance and Longevity in La Liga League Soccer Players

AbstractAnterior cruciate ligament (ACL) rupture is among the most studied sports injuries. We investigate the impact of ACL reconstruction (ACLR) on performance and longevity in La Liga to elucidate performance parameters impacted after surgery in professional soccer players and variables impacting return-to-play (RTP).Demographic and performance data for La Liga players with ACLR between 1993 and 2020 were collected three seasons before and after injury and compared with two healthy controls. Analysis was conducted between and within ACLR and control groups. Pearson's correlation coefficients and a multiple linear regression model analyzed relationships between demographic variables and RTP.After exclusion, 23 professional soccer players were identified for the ACLR group. One year after index, ACLR had lower goals, shots on-target, assists, pass percentage, tackles, tackle success percentage, blocks, and clearances compared with control (p &lt; 0.05). Two years after index, ACLR had lower assists, pass percentage, and tackle success percentage than control (p &lt; 0.05). Three years after index, ACLR had fewer matches and blocks versus control (p &lt; 0.05). Pearson's correlation showed a positive correlation between experience and RTP (p = 0.001). Multiple linear regression found RTP to increase 32.66 days for each additional year of experience (p &lt; 0.001).With performance metrics showing significant decreases up to 2 years post-ACLR but largely recovering within 3 years of RTP, results support that soccer players undergoing ACLR eventually recover to preinjury levels of play. Players should be counseled on initial declines in performance metrics the first few years after RTP.

Functional Assessment of Anterior Cruciate Ligament Reconstruction Using Peroneus Longus vs. Hamstring Tendon at 6, 12, And 24 Months Follow Up: A Meta-Analysis

Background: Anterior cruciate ligament (ACL) tear occurs between 29 to 38 cases per 100.000 people annually with more than half of cases requiring an ACL reconstruction. Peroneus longus tendon (PLT) has growing popularity as an autograft for ACL reconstruction providing comparable outcomes with proper graft diameter size, lack of donor site morbidity and uncomplicated harvesting technique. Unfortunately, certain studies did not agree with the superiority of PLT to the standard hamstring tendon (HT). Objective: The aim of study is to compare the knee functional outcome of an ACL reconstruction using peroneus longus and hamstring tendon according to recent publications. Methods: This study conducted a thorough systematic search for relevant scientific reports on multiple medical databases, including PubMed, Embase, and Google Scholar, using a combination of keywords such as "peroneus longus," “hamstring tendon,” "ACL reconstruction," “IKDC,” and “Lysholm”. The search was performed in April 2013-2023, resulting in 1567 studies. Two reviewers (RR, WA) independently screened the abstracts and reference lists, with any discrepancies resolved through consensus, concluding 5 included studies. Results: Five studies are included with a total of 538 patients consisting of 267 patients who underwent ACL reconstruction with PLT and 271 patients who underwent ACL reconstruction with HT. Up to 24 months follow-up, there are equally balanced satisfactory functional outcomes between ACL reconstruction using peroneus longus and hamstring tendon, in terms of IKDC (I2 = 74%; SMD = 0.08 95%CI, -0.21 to 0.38; p = 0.57) and Lysholm score (I2 = 75%; SMD = 0.06 95%CI, -0.27 to 0.39; p = 0.73). Conclusion: ACL reconstruction using the peroneus longus tendon is a safe and effective procedure with excellent short to long term functional outcome of the knee.

Lateral femoral impaction fractures during an ACL tear extend posteriorly on the weight-bearing area of the tibiofemoral joint.

Posterior elongation of the physiological terminal sulcus (TS) due to lateral femoral condyle impaction fracture (LFC-IF) after an anterior cruciate ligament (ACL) tear could potentially decrease the weight-bearing area of the tibiofemoral joint, decrease the tension on lateral meniscus and cause flattening of the LFC which would influence rotational knee motion and cause anisometry of the lateral and anterolateral stabilizers. Therefore, the purpose of the study was to assess if the LFC-IF elongates the physiological TS posteriorly. One hundred patients magnetic resonance images (MRIs) (75 males, 25 females, mean age 32.2 years, SD = 8.2) were included with a 1:1 ratio between the full-thickness ACL tear group and the control group (patients with knee MRI performed due to other reasons, with no tear of ACL on MRI and negative clinical tests). Two independent raters evaluated the sagittal T1-weighted preselected MRI scans. The principal measurement of interest was the distance from the intersection of the Blumensaat line with subchondral bone to the posterior border of the TS/LFC-IF. The median distance from the Blumensaat line to the posterior border of the TS/LFC-IF was significantly higher in the ACL tear group: 14.3 mm, interquartile range (IQR) = 11.6-16.4 mm versus control group: 12.8 mm, IQR = 9.0-15.0 mm, p = 0.038. Intrarater and inter-rater reliabilities were >0.90. LFC-IF after full-thickness ACL tear significantly elongates the physiological TS in the posterior direction. Level III.

Evaluation of Return to Military Activities after Combining Anterior Cruciate Ligament Reconstruction with Modified Lateral Extra-articular Tenodesis Versus Anterior Cruciate Ligament Reconstruction Alone in Primary Anterior Cruciate Ligament Tear in Soldiers. A Randomized Comparative Study

Abstract Background: This study aimed to assess the clinical result, complications, failure rate, and return to resuming military duty of a single-stage anterior cruciate ligament reconstruction (ACLR) procedure utilizing quadrupled semitendinosus tendon graft joint with modified lateral extra-articular tenodesis (LET). This study evaluates the potential impact of combined modified LET with ACLR versus ACLR alone on the rate of return to high-impact military activities, which we call return to sports (RTSs), and the subsequent rate of the anterior cruciate ligament (ACL) graft failure. Materials and Methods: A total of 198 soldiers with primary ACL tears with a high-grade pivot test (grade 3) were included and randomized using the simple randomized method and divided into two groups. A consecutive cohort of military personnel with an isolated ACL tear undergoing ACLR with modified LET (group A, n = 116) and ACLR alone (group B, n = 82) were analyzed between 2016 and 2021. Both groups were followed up for a minimum of 2 years. Soldiers underwent a survey evaluating knee function (knee injury and osteoarthritis outcome score [KOOS]), RTS criteria (RTS type), symptoms (International Knee Documentation Committee [IKDC] subjective), activity level (Tegner score), and fear of movement (Tampa Scale of Kinesiophobia-11) to assess psychological readiness for sport participation. Results: Among these, a mean age of 32 ± 2.93 years underwent primary ACLR with modified LET (n = 116) or without LET (n = 82) procedure. A total of 31 soldiers (15.6%) experienced ACL graft failure, including 26 (31.7%) reconstructions without LET and 5 (4.3%) with LET. Combined with LET during primary ACLR, it lowered the risk of graft failure by 2.8 times. Multivariable analysis revealed a significant reduction in graft rupture risk (relative risk = 0.325, P = 0.029) associated with LET compared to ACLR alone after adjusting for age, anthropometric factors, and tibial slopes. 105 out of 113 (90.5%) soldiers were able to return to military duty in group A (combined ACLR with modified LET), whereas 51 of 81 (62.9%) of the soldiers who underwent ACLR alone (group B) returned to military duty (P = 0.05). Conclusion: At 24 months postoperatively, combined ACLR plus LET showed a significantly higher RTS rate than ACLR alone. The combined ACLR with the modified LET group also showed a lower failure rate than the ACLR alone group. No marked differences were observed in KOOS sub-scores, IKDCsubjective, and Tegner activity scores.

This paper aims to provide comprehensive knee injury prevention and rehabilitation strategies for basketball players, enhancing their athletic performance and joint health.

Players in the Women's National Basketball Association Are More Likely to Tear Their Anterior Cruciate Ligament if They Are a Guard, Forward, or Driving to the Basket: A Case-Control Study.

The Women's National Basketball Association (WNBA) has grown in popularity since its induction in 1996. Furthermore, it is well known that female athletes are at an increased risk of anterior cruciate ligament (ACL) tears compared with their male counterparts. The purpose was to examine the player positions and player movements during basketball games and practices that contribute to ACL tears in WNBA players. Player position and demographics from WNBA players who suffered an ACL tear from 1996 to 2021 were collected from publicly available sources. Entertainment and Sports Programming Network (ESPN) news reports and video analysis were reviewed to determine what movements each player was performing when the injury occurred. Injured players were matched with two noninjured players by age, position, height, and league experience. Performance statistics were collected one season prior to injury and compared with the matched controls. A total of 62 WNBA players with ACL injuries were identified with an average age of 26.7 (±3.9) years. More guards and forward were seen in the injured cohort and more players were injured while driving to the basket (p < 0.05). ACL injuries occurred more commonly during games than in practice (p < 0.05). Compared with controlled match cohort, the players who suffered ACL tears started more games (p = 0.007), had higher minutes played per game (p = 0.003), more field goals per game (p = 0.04), more field goal attempts per game (p = 0.03), more 3-point attempts per game (p = 0.04), more rebounds per game (p = 0.04), more steals per game (p = 0.02), and more points per game (p = 0.02). WNBA guards and forward were more likely to tear their ACL, especially while driving to the basket during real game play. Additionally, players with higher playing times, rebounds, and steals per game had higher rates of ACL tears. However, there was no impact on their performance on season statistics after returning to sport. LEVEL OF EVIDENCE: III.

Anterior Cruciate Ligament Tear: Individualized Indications for Non-Operative Management.

Anterior cruciate ligament (ACL) rupture represents a common sports injury that is mostly managed operatively. However, non-operative treatment can also play a role, despite the limited high-quality published data on ACL tear management. Both methods have shown favorable outcomes, but clear guidelines based on high-quality research are lacking. Several factors should be considered and discussed with the patient before deciding on the best treatment method. These include patient characteristics and expectations, concomitant injuries, and clinical evaluation, with laxity or/and instability being one of the most essential parameters examined. This should eventually lead to an individualized approach for each patient to ensure the best possible outcome. This review aims to delve into all parameters that are related to ACL rupture and guide physicians in choosing the most appropriate treatment method for each patient.

Evaluation of the reliability and accuracy of MRI for the diagnosis of meniscal ramp lesions.

Meniscal ramp lesions are a special type of meniscal injury that affects the periphery of the posterior horn of the medial meniscus and/or its meniscocapsular attachments, strongly associated with anterior cruciate ligament (ACL) tears. Due to their location, these lesions can be missed arthroscopically so it is essential to diagnose them on preoperative magnetic resonance imaging (MRI). To evaluate the accuracy of MRI in detecting meniscal ramp lesions in patients with ACL tears using arthroscopy as the reference standard. Two musculoskeletal radiologists, blinded to the surgical findings, retrospectively and independently evaluated 106 knee MRI scans for the presence of meniscal ramp lesions in non-consecutive patients who underwent arthroscopic ACL reconstruction between January 2019 and July 2022 by a single surgeon at one institution. Having arthroscopy as reference, the diagnostic sensitivity and specificity as well as the positive and negative predictive values (PPV/NPV) of the MRI scans were calculated. Cohen's kappa coefficient was used to test inter-observer reliability. A P value <0.05 was considered statistically significant. In the study group of 106 patients (72 men, 34 women; mean age = 33.84 ±13.12 years), 76 had an arthroscopy-confirmed meniscal ramp lesion, while 30 did not. The sensitivity and specificity of MRI for the detection of meniscal ramp lesion were 88% and 87%, respectively. The PPV and NPV were 94% and 74%, respectively. Inter-rater reliability was excellent (k = 0915). This study demonstrates that MRI can accurately detect meniscal ramp lesions.
