“…Return to sport is of primary importance for a successful outcome following anterior cruciate ligament reconstruction (ACLR) [ 1 ]. However, athletes who do return to sport after ACLR are significantly more likely to sustain a second ACL injury compared to their previously uninjured counterparts [ 2 , 3 , 4 ], leading to inferior functional outcomes [ 5 ]. Hence, it is important to mitigate secondary injury risk through the identification and treatment of associated risk factors.…”

(1) Background: Biomechanics during landing tasks, such as the kinematics and kinetics of the knee, are altered following anterior cruciate ligament (ACL) injury and reconstruction. These variables are recommended to assess prior to clearance for return to sport, but clinicians lack access to the current gold-standard laboratory-based assessment. Inertial sensors serve as a potential solution to provide a clinically feasible means to assess biomechanics and augment the return to sport testing. The purposes of this study were to (a) develop multi-sensor machine learning algorithms for predicting biomechanics and (b) quantify the accuracy of each algorithm. (2) Methods: 26 healthy young adults completed 8 trials of a double limb jump landing task. Peak vertical ground reaction force, peak knee flexion angle, peak knee extension moment, and peak sagittal knee power absorption were assessed using 3D motion capture and force plates. Shank- and thigh- mounted inertial sensors were used to collect data concurrently. Inertial data were submitted as inputs to single- and multiple- feature linear regressions to predict biomechanical variables in each limb. (3) Results: Multiple-feature models, particularly when an accelerometer and gyroscope were used together, were valid predictors of biomechanics (R2 = 0.68–0.94, normalized root mean square error = 4.6–10.2%). Single-feature models had decreased performance (R2 = 0.16–0.60, normalized root mean square error = 10.0–16.2%). (4) Conclusions: The combination of inertial sensors and machine learning provides a valid prediction of biomechanics during a double limb landing task. This is a feasible solution to assess biomechanics for both clinical and real-world settings outside the traditional biomechanics laboratory.

“…Sports injuries around the knee, which are common in the paediatric age group, are treated surgically to prevent secondary injuries that may occur in the future. 5 It has been reported that 90% of the paediatric age group can return to sports with postoperative rehabilitation and in a shorter time than adults. 6 This is explained by the fact that the paediatric age group is less afraid of the risk of re-injury and has a better neuromuscular structure than adults.…”

Purpose The aim of this study was to compare the injury patterns of orthopaedic trauma patients in the paediatric age group who presented to our hospital during and after lifting the curfew due to the pandemic, with the patients of the same age group who presented to our institution during the same time period last year. Methods Patients, aged 0 years to 18 years, who presented to our clinic between 21 March 2020 and 31 May 2020 (during curfew) (Group A1, n = 111), between 01 June 2020 and 31 August 2020 (Group A2, n = 214) and during the same periods in 2019 Group B1 (n = 220) and Group B2 (n = 211) were included. Patients with pathological fractures, traumas occurring earlier than the aforementioned date range and those consulted while being hospitalized in another department were excluded from study. Patients’ demographics, the department they presented to, the anatomical region affected by trauma, trauma mechanism, the location of trauma, the treatment applied and the length of hospital stay were recorded. Results The prevalence of outdoor traumas (72.9% versus 61.1%), high-energy traumas (40.1% versus 26.5%), the rate of the patients treated with surgery (28% versus 17.1%) and the rate of admission to the emergency department (90.2% versus 58.3%) were significantly higher in Group A2 when compared with Group B2 (p < 0.05). Conclusion The significant increase was observed in the number of outdoor injuries, high-energy traumas and fracture patterns that require surgical treatment during the first three months following the lift of the curfew, in comparison with the corresponding dates from last year. We think that children’s lower extremity muscle strength and neuromuscular control was decreased due to staying home for a prolonged period of time. Level of Evidence Level III, Case-control study.

“…Rupture is typically treated with surgical reconstruction to re-establish structural integrity of the knee joint, with the new ACL often crafted through harvesting of the patella, quadriceps, or semitendinosus/gracilis tendon. 7 Worldwide, the incidence of ACL reconstructive surgery is increasing, [8][9][10][11] with recent published evidence suggesting 20%-25% of patients will sustain a secondary injury, [12][13][14] and 36% develop knee joint osteoarthritis within 10 years following surgery. 15 Rupture and subsequent reconstructive surgery of the ACL is known to cause negative effects on the morphology and function of the quadriceps muscle group.…”

Anterior cruciate ligament (ACL) injury and reconstructive surgery is known to cause long-term negative impacts on quadriceps muscle size. With the known link between reduced muscle size and the health and functioning of the knee joint, it is important rehabilitation programs aim to restore quadriceps mass as safely and quickly as possible. However, a comprehensive review of interventions investigating the impact of training interventions on quadriceps muscle size in ACL-reconstructed individuals has yet to be undertaken. Therefore, this article systematically reviews the evidence investigating training interventions that aim to improve quadriceps size in ACL-reconstructed individuals. A literature search was performed in MEDLINE, SPORTDiscus, CINAHL, and Web of Science. Observational and experimental studies investigating training interventions impact on quadriceps muscle size in ACL-reconstructed individuals were included. Risk-of-bias assessment (Downs and Black) was completed on included studies, data was extracted, and a best evidence synthesis was undertaken. 718 articles were returned in the initial search; following screening, six articles were included in this review. Results from the best evidence synthesis suggest there is moderate evidence for eccentrically biased training to increase quadriceps size. Both traditional resistance training and blood flow restriction training showed conflicting results for improving quadriceps size. However, the results for traditional resistance training and blood flow restriction training may have been limited by differing imaging methods across included studies. This review highlights the positive changes in quadriceps size seen following traditional, eccentrically biased and blood flow restriction exercise interventions in ACL-reconstructed limbs, despite the limited number of studies. Further work is needed to identify and optimize the best practice for hypertrophic training in these individuals.
