- A stringent outcome assessment is a key aspect of establishing evidence-based clinical guidelines for anterior cruciate ligament (ACL) injury treatment. To establish a standardized assessment of clinical outcome after ACL treatment, a consensus meeting including a multidisciplinary group of ACL experts was held at the ACL Consensus Meeting Panther Symposium, Pittsburgh, Pennsylvania, USA, in June 2019. The aim was to establish a consensus on what data should be reported when conducting an ACL outcome study, what specific outcome measurements should be used, and at what follow-up time those outcomes should be assessed. The group reached consensus on 9 statements by using a modified Delphi method. In general, outcomes after ACL treatment can be divided into 4 robust categories: early adverse events, patient-reported outcomes (PROs), ACL graft failure/recurrent ligament disruption, and clinical measures of knee function and structure. A comprehensive assessment after ACL treatment should aim to provide a complete overview of the treatment result, optimally including the various aspects of outcome categories. For most research questions, a minimum follow-up of 2 years with an optimal follow-up rate of 80% is necessary to achieve a comprehensive assessment. This should include clinical examination, any sustained reinjuries, validated knee-specific PROs, and health-related quality of life questionnaires. In the midterm to long-term follow-up, the presence of osteoarthritis should be evaluated. This consensus paper provides practical guidelines for how the aforementioned entities of outcomes should be reported and suggests the preferred tools for a reliable and valid assessment of outcome after ACL treatment.

- Purpose To compare patient-reported and clinician-reported outcomes, and radiographic results between patients who had had revision ACL reconstruction and those who had had primary ACL reconstruction. Design Systematic review and meta-analysis Data sources The MEDLINE, CINAHL, EMBASE and SPORTDiscus electronic databases were searched on 6 August 2015, using 3 main concepts: (1) revision ACL reconstruction, (2) primary ACL reconstruction and (3) treatment outcomes. Eligibility criteria for selecting studies Articles that compared patient-reported or clinician-reported outcomes or radiographic results between patients who had had revision ACL reconstruction and those who had had primary surgery with a minimum of 2 years follow-up were included. The outcomes evaluated were the Lysholm Knee Scoring Scale, objective International Knee Documentation Committee (IKDC) classification, Tegner Activity Scale, side-to-side difference in anterior tibial translation measured with KT-1000/2000 arthrometer, pivot shift test, tibiofemoral osteoarthritis grading on plain radiographs and subsequent knee surgeries. Results 8 studies (300 revision ACL reconstructions and 413 primary ACL reconstructions) were included in the meta-analysis. Patients who had had revision surgery reported inferior Lysholm Knee Scoring Scale scores (mean difference: 7.8 points), had inferior clinician-reported knee function as assessed with the objective IKDC classification (IKDC category A: 27% vs 57%; IKDC category C or D: 22% vs 8%) and pivot shift test (grade II or III: 7% vs 2%), and more radiographic evidence of tibiofemoral osteoarthritis (50% vs 25%) compared with patients who had had primary surgery. Conclusions Revision ACL reconstruction restored similar anterior-posterior knee laxity compared with primary ACL reconstruction. Patients who had had revision surgery reported inferior Lysholm Knee Scoring Scale scores, had inferior clinician-reported knee function and more radiographic signs of tibiofemoral osteoarthritis compared with patients with primary ACL reconstruction.

- To evaluate the time to return to playing following acute Achilles tendon rupture (ATR) and surgical repair in professional male football (soccer) players.Professional male football (soccer) players who sustained an ATR and underwent surgical repair were identified through internet-based injury reports from January 2008 to August 2018. Only League 1 and 2 players with injuries who had at least 1 year of follow-up from the search date were included. Injury history and time to return to play were retrieved from the public platform transfermarkt.com. For athletes who competed for at least two seasons after returning to play, re-ruptures and number of matches played were reported.118 athletes (mean age 27.2±7.2 years) were included. 113 (96%) returned to unrestricted practice after a mean of 199±53 days, with faster recovery in players involved in national teams. Return to competition was after a mean of 274±114 days. In the 76 athletes with at least two seasons of follow-up, 14 (18%) did not compete at the pre-injury level during the two seasons following the index injury. Six players (8%) sustained a re-rupture within the first two seasons after return to play; four re-ruptures were in footballers who returned to play <180 days after injury. Age >30 years and re-ruptures had higher odds ratios of not returning to the same level of play.96% of professional male football players who underwent surgery to repair an ATR returned to unrestricted practice and then competition after an average time of 7 and 9 months, respectively. However, 18% did not return to the same level of play within the two seasons following their return, with a higher risk in those experiencing a re-rupture.

- Objective To determine whether patient-related factors, concomitant injuries and preoperative knee laxity could predict a patient acceptable symptom state (PASS) in the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) at 1 and 2 years follow-up after anterior cruciate ligament (ACL) reconstruction in a multicentre cohort. Methods Patients between 14 and 50 years of age who underwent single-bundle ACL reconstruction with hamstring tendon autograft within 1 year from the index injury were eligible. Additionally, only patients who completed the IKDC-SKF questionnaire at 1 or 2 years of follow-ups were included. Preoperative knee laxity assessment of patients in the awake state was performed using rolimeter, the Lachman and the pivot-shift test. The pivot shift was graded according to the IKDC criteria and also quantified by the use of non-invasive technology for (1) lateral tibial translation and (2) tibial acceleration. The quantitative pivot shift (QPS) was examined in the awake state and under anaesthesia (EUA). Univariable logistic regression models were performed with achieving PASS in the IKDC as the dependent variable. Results A total of 86 patients had complete data on the IKDC-SKF score at 1-year follow-up, of which 67 patients (77.9%) achieved PASS (age 24.8±9.3 years, 43% females). Two-year data were available for 50 patients, of which 39 patients (78.9%) achieved PASS (age 23.9±9.2 years, 42.0% females). A low-grade manual pivot shift according to IKDC grading had increased odds of achieving PASS at 1 year (OR=2.96 (95% CI 1.01 to 8.66), P<0.05) compared with patients who displayed a high-grade pivot shift preoperatively. However, this was not confirmed by the preoperative QPS measures (awake: tibial translation; OR=0.99,(95% CI 0.72 to 1.35), (n.s.), acceleration; OR=1.04,(95% CI 0.68 to 1.59), (n.s.) EUA: tibial translation; OR=1.02 (95% CI 0.78 to 1.31), (n.s.), acceleration; OR=1.14 (95% CI 0.93 to 1.40), (n.s.)). None of the studied variables of patient characteristics, concomitant injuries or knee joint laxity predicted PASS at the 2-year follow-up. Conclusion Almost four in every five patients were able to achieve PASS 1 and 2 years after anatomic single-bundle ACL reconstruction. The presence of preoperative low-grade pivot shift increased the odds of achieving an acceptable level of knee function 1 year after ACL reconstruction compared with high-grade pivot shift; however, QPS did not confirm achievement of PASS in this study.

- Health state utility values are derived from preference-based measurements and are useful in calculating quality-adjusted life years (QALYs), which is a metric commonly used in cost-effectiveness studies. The purpose of this study was to convert the Achilles Tendon Rupture Score (ATRS) to the preference-based European Quality of Life-5 Dimension Questionnaire (EQ-5D) by estimating the relationship between the two scores using mapping.Data were collected from a randomised controlled trial, where 100 patients were treated either surgically or non-surgically for Achilles tendon rupture. Forty-three and forty-four patients in surgical group and non-surgical group completed the ATRS and the EQ-5D alongside each other during follow-up at three time points. Different models of the relationship between the ATRS and the EQ-5D were developed and analysed based on direct mapping and cross-validation. The model with the lowest mean absolute error was observed as the one with the best fit.Among the competing models, mapping based on using a combination of the ATRS items four, five, and six associated with limitation due to pain, during activities of daily living and when walking on uneven ground, produced the best predictor of the EQ-5D score.The present study provides a mapping algorithm to enable the derivation of utility values directly from the ATRS. This approach makes it feasible for researchers, as well as medical practitioners, to obtain preference-based values in clinical studies or settings where only the ATRS is being administered. The algorithm allows for the calculation of QALYs for use in cost-effectiveness analyses, making it valuable in the study of acute Achilles tendon ruptures.II.

- The purpose of this investigation was to compare the magnitude of rotatory knee laxity in patients with a partial anterior cruciate ligament (ACL) tear, those with a complete ACL tear, and those who had undergone a failed ACL reconstruction. It was hypothesized that rotatory knee laxity would increase with increasing injury grade, with knees with partial ACL tears demonstrating the lowest rotatory laxity and knees that had undergone failed ACL reconstruction demonstrating the highest rotatory laxity.A prospective multicenter study cohort of 354 patients who had undergone ACL reconstruction between 2012 and 2018 was examined. All patients had both injured and contralateral healthy knees evaluated using standardized, preoperative quantitative pivot shift testing, determined by a validated, image-based tablet software application and a surface-mounted accelerometer. Quantitative pivot shift was compared with the contralateral healthy knee in 20 patients with partial ACL tears, 257 patients with complete ACL tears, and 27 patients who had undergone a failed ACL reconstruction. Comparisons were made using 1-way analysis of variance (ANOVA) with post hoc 2-sample t tests with Bonferroni correction. Significance was set at p < 0.05.There were stepwise increases in side-to-side differences in quantitative pivot shift in terms of lateral knee compartment translation for patients with partial ACL tears (mean [and standard deviation], 1.4 ± 1.5 mm), those with complete ACL tears (2.5 ± 2.1 mm), and those who had undergone failed ACL reconstruction (3.3 ± 1.9 mm) (p = 0.01) and increases in terms of lateral compartment acceleration for patients with partial ACL tears (0.7 ± 1.4 m/s), those with complete ACL tears (2.3 ± 3.1 m/s), and those who had undergone failed ACL reconstruction (2.4 ± 5.5 m/s) (p = 0.01). A significant difference in lateral knee compartment translation was found when comparing patients with partial ACL tears and those with complete ACL tears (1.2 ± 2.1 mm [95% confidence interval (CI), 0.2 to 2.1 mm]; p = 0.02) and patients with partial ACL tears and those who had undergone failed ACL reconstruction (1.9 ± 1.7 mm [95% CI, 0.8 to 2.9 mm]; p = 0.001), but not when comparing patients with complete ACL tears and those who had undergone failed ACL reconstruction (0.8 ± 2.1 [95% CI, -0.1 to 1.6 mm]; p = 0.09). Increased lateral compartment acceleration was found when comparing patients with partial ACL tears and those with complete ACL tears (1.5 ± 3.0 m/s [95% CI, 0.8 to 2.3 m/s]; p = 0.0002), but not when comparing patients with complete ACL tears and those who had undergone failed ACL reconstruction (0.1 ± 3.4 m/s [95% CI, -2.2 to 2.4 m/s]; p = 0.93) or patients with partial ACL tears and those who had undergone failed ACL reconstruction (1.7 ± 4.2 m/s [95% CI, -0.7 to 4.0 m/s]; p = 0.16). An increasing lateral compartment translation of the contralateral, ACL-healthy knee was found in patients with partial ACL tears (0.8 mm), those with complete ACL tears (1.2 mm), and those who had undergone failed ACL reconstruction (1.7 mm) (p < 0.05).A progressive increase in rotatory knee laxity, defined by side-to-side differences in quantitative pivot shift, was observed in patients with partial ACL tears, those with complete ACL tears, and those who had undergone failed ACL reconstruction. These results may be helpful when assessing outcomes and considering indications for the management of high-grade rotatory knee laxity.Prognostic Level III.

- Objectives The purpose of this investigation was to identify clinical and demographic variables that may predict compliance, defined as patient follow-up at 1-year and 2-year postoperative appointments, after anterior cruciate ligament reconstruction (ACLR). Methods A total of 107 patients undergoing primary ACLR across four centres were prospectively followed for 2 years. Demographic and clinical data were recorded preoperatively and postoperatively, including patient-reported outcomes such as the Marx Activity Rating Scale, Cincinnati Occupational Rating Scale (CORS), International Knee Documentation Committee Subjective Knee Evaluation Form and Activities of Daily Living Scale (ADLS). Compliance was retrospectively defined using the presence or lack of outcome measures at 1-year and 2-year postoperative visits. Univariate analysis was done to compare demographic and clinical variables between compliant and non-compliant patients at 1-year and 2-year follow-up. Significant variables were entered into a logistic regression model. Significance was set at p<0.05. Results The overall rate of compliance at 1-year and 2-year postoperative appointments was 83.2% (89/107) and 57.0% (61/107), respectively. Regression analysis showed that residence in Kobe, Japan compared with Pittsburgh, USA (OR 10.28; 95% CI 1.0003 to 105.28), and ‘very strenuous’ (OR 16.74; 95% CI 3.21 to 87.43) and ‘strenuous’ (OR 18.78; 95% CI 2.01 to 175.78) preinjury activity level were independent factors associated with compliance at 1-year follow-up. At 2 years follow-up, younger age (OR 0.95; 95% CI 0.91 to 0.997), and greater preoperative score on CORS (OR 1.03; 95% CI 1.01 to 1.06) and on ADLS (OR 1.04; 95% CI 1.01 to 1.07) were independently associated with compliance. Conclusion While patients with greater level of strenuous activity were more likely to follow-up after ACL surgery at 1 year, patients who were younger and had higher preoperative function measured by CORS and ADLS were more likely to follow-up at 2 years. Differences in follow-up rates among the USA, Italy, Sweden and Japan may highlight important cultural, socioeconomic and infrastructural differences across international healthcare systems. Orthopaedic surgeons may consider the results of this study during preoperative discussion with their patients and design of future ACL clinical research trials. Level of evidence Level III, prospective cohort.

- The main goal of this work was to evaluate the pivot shift test in awake and anesthetized patients by using two different quantitative methodologies and comparing the results with the standard clinical grading, taking advantage of a multicenter international study.Patients between 16 and 50years of age undergoing primary unilateral single-bundle anterior cruciate ligament (ACL) reconstruction were considered eligible. The pivot shift test was performed pre-operatively, with the patient awake and again with the patient under general anaesthesia. The pivot shift test was clinically graded as defined by the International Knee Documentation Committee. The instrumented assessment was performed by using two non-invasive acquisition systems; specifically, a system exploiting an inertial sensor and a video-based application developed on a commercial tablet using skin markers. Lateral compartment translation and the tibial acceleration reached during joint reduction were used as quantitative parameters.A total of 103 patients were enrolled in the study. Statistically significant difference was found between the distributions of clinical grade evaluated in awake patients and those under general anaesthesia (P<0.01). Comparing awake patients to those under general anaesthesia, lower values were found both for tibial acceleration (3.7±1.5 vs 6.0±4.6m/s(2), P<0.01) and lateral compartment translation of the involved limb (2.2±1.7 vs 3.0±2.2mm, P<0.01).This study indicated that significant differences in the grading of the pivot shift test exist between awake and anesthetized patients, regardless of the use of quantitative instruments during the evaluation. Actual clinical assessment reported indeed its weakness, presenting subjective variability and dependence on tester's experience. However, several factors might influence the validity of awake examination such as experience level of examiner and cultural factors, as seen in this international multicenter study.Prospective comparative study, Level II.
