Special Issue Information

Dear Colleagues,

The anterior cruciate ligament (ACL) is one of the most commonly injured ligaments of the knee in the athletic population. The treatment of this injury very often requires the implementation of appropriate surgical interventions and long-term physical rehabilitation programs, which are necessary to safely return to the pre-injury level of activity. However, despite improvements in the management of ACL injuries, many athletes worldwide are still injured each year, making it more imperative than ever to prevent the onset of the injury and minimize—if not eliminate—the adverse effects of re-injury.

The anatomy of the athlete’s musculoskeletal system related to lower-limb joint alignment, skeletal asymmetries or deviations, non-fatigued or fatigue-induced functional imbalances, postural control, and fitness deficits are only some of the intrinsic factors which in recent years have been under continuous research.

Research related to the biomechanical analysis of injury is also ongoing, being undertaken by many investigators in an attempt to identify the sports-related factors that contribute to its provocation during the execution of athletic movements such as cuts, jumps, and landings.

Establishing effective and balanced rehabilitation programs with strength training and neuromuscular exercises that will increase athletes’ compliance continues to be pursued by clinical therapists, while simultaneously seeking methods and tests that will optimally assess athletes’ readiness before returning to sports activities.

Furthermore, wearable technology, the use of fMRI to identify brain mechanisms underlying ACL injury risk and sports-related movements, and the application of virtual reality (VR) as well as augmented reality (AR) to identify deficits and enhance neuromuscular training, consistently gain ground in individualized ACL injury prevention and rehabilitation.

This Special Issue is addressed to all those working in these areas, and welcomes original papers, review articles, and meta-analyses that provide insight into "Recent Advances in the Prevention and Rehabilitation of ACL Injuries". We are looking forward to your contributions.

A Single-Leg Vertical Hop Test Is an Effective Tool to Measure Functional Performance after Anterior Cruciate Ligament (ACL) Reconstruction

Abstract

This study evaluated the single-leg vertical hop test (SLVHT), using digital sensor technology, for the functional assessment of rehabilitation progress in patients after ACL reconstruction (ACL-R). Between January 2019 and June 2022, 143 patients (26.6 (8.9) years, m/f 66/34%) completed return-to-sport testing at 3 and 6 months after ACL-R. The jump height during SLVHT was quantified with a digital motion sensor, containing a three-axis acceleration gyroscope sensor, and the limb symmetry index (LSI) (injured/non-injured leg ratio) was calculated. Three months postoperatively, the jump height of the injured leg was 59.6% (13.5 (5.5) cm) that of the non-injured leg (22.9 (6.2) cm; p < 0.01). After 6 months, the jump height of the injured leg (18.4 (6.9) cm) improved by 44.1% compared to that at the 3-month follow-up but was still lower than the non-injured leg jump height (23.2 (7.0) cm, p < 0.001; LSI = 79.6%). Men jumped higher than women, but their LSI was not different at 3 (59.6 vs. 59.5%) and 6 months (80.6 vs. 77.8%). Regression analysis identified the non-injured leg jump height as the primary independent predictor of the jump height of the injured leg (β = 0.776, T = 51.506, p < 0.001). SLVHT, using digital sensor technology, is a simple and cost-effective functional test to assess rehabilitation progress after ACL-R, with the potential for multi-centre data analysis. Full article

Pre-Season ACL Risk Classification of Professional and Semi-Professional Football Players, via a Proof-of-Concept Test Battery

by Charis Tsarbou, Nikolaos I. Liveris, Sofia A. Xergia, Maria Tsekoura, Konstantinos Fousekis and Elias Tsepis

Abstract

This study aimed to identify football players at high risk (HR) for anterior cruciate ligament (ACL) injury via a four-test battery and assess possible factors affecting classification. Ninety-one professional and semi-professional male athletes participated in a field-based pre-season screening. The cut-off points of the test battery were 10% acknowledged inter-limb asymmetry limit for quadriceps and hamstring isometric strength and single-leg triple hop for distance, in addition to the upper limit of 6 errors in the landing error scoring system (LESS). Additional assessment of hip adductors and core stability completed the global functional profile of the players. Sixty-one players were identified as HR and thirty as low-risk (LR) for ACL injury. Discriminant analysis showed that the proposed test battery classified accurately 78.0% of them, with 91.8 sensitivity and 61.9% specificity. Only four misclassified players in the LR group were at risk of inadequate treatment. All participants were considered healthy, and history of a previously rehabilitated injury did not interfere with the results. LESS seems to be the best predictor for injury-risk grouping. Prone bridge time was also a whole-body variable discriminating between groups. The proposed test battery provides a promising option for field-based pre-season ACL risk assessment of football players and needs to be studied prospectively. Full article

Abstract

The quadriceps femoris muscle (QF) is of clinical importance since it has been correlated with pathologies at knee level, such as anterior cruciate ligament (ACL) injury, pain processes and complex clinical conditions. Among the variables that have been related to these clinical conditions are anthropometric measurements, architecture and muscular behavior of the QF. The aim of this study was to determine the relationship between the rectus femoris (RF) and vastus intermedius (VIM) muscles’ behavior measured by rehabilitative ultrasound imaging (RUSI) M-mode under maximal voluntary isometric contraction (MVIC) and anthropometric measurements. This was a cross-sectional, observational study. Sixty-two asymptomatic volunteers were included (20.42 ± 4.97 years, most women 59.7%). RUSI measurements were muscle contraction/rest thickness and contraction/relaxation velocity. Anthropometric measurements were, lower limb length, RF length, QF tendon length, distance between spines, proximal, middle and distal thigh perimeter. Statistically significant correlations (p < 0.05) were found between VIM thickness at rest and contraction with thigh perimetry, RF length and dominant lower limb length. For the RF, a correlation was found between the thickness at rest and the length of this muscle (p = 0.003). There is a correlation between anthropometric variables and muscular behavior measured by RUSI M-mode. Full article

The Utilization of Lean Six Sigma Methodologies in Enhancing Surgical Pathways and Surgical Rehabilitation

by Seán Paul Teeling, Michelle McGuirk, Martin McNamara, Marie McGroarty and Aileen Igoe

Appl. Sci. 2023, 13(12), 6920; https://doi.org/10.3390/app13126920 - 08 Jun 2023

Abstract

The authors offer their perspective on the application of Lean Six Sigma methodology to surgical pathways, from referral to post-operative rehabilitation, and how it has resulted in sustainable improvements in patient outcomes, and patient and staff satisfaction. The origin of Lean Six Sigma is described before considering its application to improving scheduled surgical care. The concept of ‘flow’, and its relevance to pre-, intra-, and post-operative care, is discussed as well as the role of Lean Six Sigma in supporting innovation and in promoting an organizational culture that promotes openness to new ideas. The elements of the methodology that render it especially suitable for the redesign of surgical pathways include eliciting the customer voice, co-design, enabling system awareness and inculcating a continuous improvement mindset. The necessary conditions for the successful implementation of Lean Six Sigma initiatives include managerial support, high-quality education and training, and alignment with organizational strategy. Future directions for practice and research are discussed before presenting a key finding from the literature and from the authors’ collective experience: Lean Six Sigma initiatives will not lead to sustainable improvements where the key elements of the methodology are not recognized and enacted, and where the necessary conditions are absent.
