- Introduction: Achilles tendon ruptures (ATRs) may occur at varying locations with ruptures at the mid-substance (MS) of the tendon most common, followed tears at the musculotendinous (MT) junction. There is scant literature about the outcome of MT ATR. This study compared the outcome of patients with a MT ATR with patients following a MS ATR. Methods: The diagnostic features and clinical outcome of 37 patients with a MT ATR were compared with a cohort of 19 patients with a MS ATR. Patients in both groups were managed non-operatively and received the same rehabilitation protocol with weight-bearing rehabilitation in protective functional brace. Results: From February 2009 to August 2023, 556 patients presented with an ATR. Of these, 37 (6.7 %) patients were diagnosed with a MT tear. At final follow-up, at 12 months following injury, the MT group reported an Achilles tendon total rupture score (ATRS) of mean (standard deviation (SD)) of 83.6 (3.5) (95 % confidence interval (CI) 81.8, 85.4) and median (inter-quartile range (IQR)) ATRS of 86 points (78–95.5) and the MS group mean (SD) of 80.3 (8.5) (95%CI) 76.1, 80.5) and median (IQR) of 87 points (59–95) (p = 0.673). Functional evaluation, however, revealed statistically significant differences in mean (SD) heel-rise height index MT group 79 % (25) (95%CI 65.9, 92.1) and MS group 59 % (13) (95%CI 51.9, 67.1) (p = 0.019). In the MT rupture group, there were considerably less complications than the MS rupture group. Conclusions: When managed non-operatively, with only a 6 weeks period of brace protection, patients have little limitation although have some residual reduction of single heel-rise at the one-year following MT ATR. Level of evidence: IV.

- Anterior cruciate ligament (ACL) reconstruction techniques have evolved over the past four decades. There is evidence that non-anatomic reconstruction techniques, such as traditional transtibial drilling, fail to recreate the native anatomy of the ACL, which can lead to increased rotatory knee instability, revision risk, and post-traumatic osteoarthritis. Anatomic ACL reconstruction has emerged as the gold standard, with the goal of restoring the patient's native anatomy and knee kinematics. This review will summarise the relevant anatomy, modern anatomic ACL reconstruction techniques, and literature supporting anatomic ACL reconstruction as the new paradigm. Level of evidence: Level V, review article.

- 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. Level of evidence Level III, prospective cohort.

- Background: The evidence supporting best practice guidelines in the field of cartilage repair of the ankle is based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on "terminology for osteochondral lesions of the ankle" developed at the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. Methods: Forty-three international experts in cartilage repair of the ankle representing 20 countries were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within four working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed, and the available evidence for each state-ment was graded. Discussion and debate occurred in cases where statements were not agreed on in unanimous fashion within the working groups. A final vote was then held, and the strength of consensus was characterised as follows: consensus, 51%-74%; strong consensus, 75%-99%; unanimous, 100%. Results: A total of 11 statements on terminology and classification reached consensus during the 2019 Interna-tional Consensus Meeting on Cartilage Repair of the Ankle. Definitions are provided for osseous, chondral and osteochondral lesions, as well as bone marrow stimulation and injury chronicity, among others. An osteochondral lesion of the talus can be abbreviated as OLT. Conclusions: This international consensus derived from leaders in the field will assist clinicians with the appro-priate terminology for osteochondral lesions of the ankle.

- Objective To determine the relationship between preoperative static knee joint laxity and non-invasive quantitative pivot shift (QPS) in patients with anterior cruciate ligament (ACL) rupture. Methods Patients with an ACL injury participating in a multicentre trial were analysed if they had complete preoperative data on the following laxity tests: the rolimeter, the KT-1000 (134N and manual maximum force), the Lachman, the anterior drawer and QPS. The QPS was assessed via a non-invasive inertial sensor system and an image analysis system for tibial acceleration and lateral tibial translation, respectively. Awake examination and examination under anaesthesia (EUA) were performed. Correlation between absolute values of static laxity and the QPS for each leg was assessed by Spearman’s rho. The Lachman and the anterior drawer were dichotomised into low- and high-grade, and differences between the groups in terms of continuous values of QPS were assessed. Results A total of 58 patients were included (41.4% women, mean age 27.1±9.8 years). Awake static laxity and QPS acceleration were negatively correlated in the ACL-deficient knee, meaning that a greater acceleration correlated to a lesser static tibial translation, and vice versa. The mean QPS acceleration correlated with the static tests as follows: the rolimeter r=−0.30 (P=0.024), the KT-1000 134N r=−0.25 (P=0.06) and the KT-1000 manual maximum r=−0.37 (P=0.004). A negative correlation between awake QPS acceleration and the static tests was also shown for the non-involved knee. Patients with a high-grade Lachman’s test in the EUA had significantly greater QPS acceleration (P=0.0002) and QPS translation (P<0.001) compared with patients with a low-grade. The corresponding analysis for the anterior drawer showed a significantly greater QPS translation in the high-grade group (P=0.01), while no differences were found in the QPS acceleration. Conclusion Static anteroposterior and dynamic knee laxities, as presented by QPS, are poorly correlated in the ACL-deficient knee and should therefore be considered as separate entities of the knee examination. These findings strengthen the implementation of non-invasive technology for quantification of the pivot shift when establishing treatment algorithms for ACL reconstruction.
