<p><strong><em>Outline: </em></strong><em>Anterior Knee Pain (AKP) is the most prevalent injury in running. Growing evidence suggests that hip muscle imbalance plays a role in the development of AKP. Gluteus Medius (GMed) is the main abductor of the hip and also stabilises the pelvis during gait. Studies show that hip-abduction strength is decreased in populations with AKP. This relates to increased hip-adduction, hip internal rotation and knee abduction, which are associated with higher patellofemoral contact pressures. <strong>Objective:</strong> The main aim of this study is to determine whether a standing exercise programme will improve hip-abductor strength. The second aim of the study is to determine whether there will be a decrease in running-related pain after completing a six-week standing exercise programme. </em></p><p><strong><em>Design: </em></strong><em>Within-participant pre-test/post-test comparative trial.</em></p><p><strong><em>Setting:</em></strong><em> The Sport’s Clinic at the Malta Football Association. Ta Qali National Stadium (Malta).</em></p><p><strong><em>Main outcome measures: </em></strong><em>GMed torque was measured using a Biodex® System 3 isokinetic dynamometer as demonstrated by Brent et al (2013). The Numerical Rating Scale was used to measure pain related to running. </em></p><p><strong><em>Results: </em></strong><em>Pre-test torque scores were higher on the affected side. Scores on the affected side improved by 22.81% from a mean baseline average of 96.00Nm/kg to 117.86Nm/kg, (p-value 0.013). Scores on the unaffected side improved by 27.97% from a mean baseline average of 90.14Nm/kg to 115.29Nm/kg (p-value 0.031). Post-test scores were more balanced between limbs. Pain scores decreased from 5.29 as measured on the NRS to 1.00 (p-value 0.000). </em></p><p><strong><em>Conclusion: </em></strong><em>Standing exercises aimed at strengthening the hip-abductors may prove to be a valid intervention for prevention and rehabilitation of AKP. However, better quality studies are needed in order to validate this.</em><em></em></p>

Abstract Background: Anterior knee pain (AKP) is a common limitation to children’s participation in social and physical activities. Therefore, to prevent the occurrence and protraction of AKP, it is crucial to identify risk factors. The purpose of this study was to clarify the factors associated with the occurrence and protraction of AKP in children and adolescents. Method: A three-year prospective cohort study was conducted with children and adolescents aged 8–14 in Japan. We recorded the occurrence of AKP, heel buttock distance, straight leg raising angle (SLRA), dorsiflexion angle of the ankle joint, and the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS). Logistic regression analysis was performed to calculate the odds ratio (OR) for each predicted risk factor for the occurrence and protraction of AKP among subjects without AKP at baseline. Results: We recruited 1,254 children and adolescents for the present study, and 1,133 children and adolescents who did not have AKP at baseline were included in the analysis. Six to nine percent of the subjects developed AKP annually. A high HSS Pedi-FABS score significantly predicted AKP occurrence (in 2017, OR 1.07, 95% CI 1.02−1.12, p = 0.003; in 2018, OR 1.05, 95% CI 1.01−1.10, p = 0.025). Of the participants, 32.9% developed chronic AKP during the follow-up period. When 8-year-old was used as a reference age, 13-year-old subjects (right side, OR 2.37, 95% CI, 1.00−5.61, p = 0.05) and 14-year-old subjects (right side, OR 2.57, 95% CI, 1.00−6.60, p = 0.049; left side, OR 6.32; 95% CI 1.33−30.00, p = 0.020) were at a significantly higher risk of AKP protraction. Conclusions: This study showed that a greater physical activity level was a risk factor for the onset of anterior knee pain in childhood. In addition, one-third of the children and adolescents developed chronic knee pain, and elderly adolescents were at a higher risk of protraction.

Background: Various factors predispose athletes with Anterior Knee Pain (AKP) making a holistic assessment & rehabilitation inevitable. Due to minimal rehabilitation services in under-resourced communities, runners are likely to report poorer health outcomes compared to other communities. Objective: The purpose was to report on the prevalence and determine extrinsic risk factors for AKP among runners in under-resourced communities. Materials & Methods: This was a cross-sectional study which included a population of 347 runners. Convenience sampling was used to recruit 183 participants aged between 13 and 55 with no history of knee surgery, traumatic or degenerative knee conditions. Questionnaires were used to collect data on AKP prevalence, and extrinsic risk factors. The SPSS (version 25) was used to analyse the data. Data were presented as frequencies and percentages and the results from chi-square and logistic regression tests. Results: Forty percent (40%) of participants presented with AKP, particularly males (n=106, 58%), youth (n=94, 51%) and participants with 3–5 years of running experience (n=57, 31%). Anterior knee pain was associated with age (X2=6.484, p=0.039) and running experience (X2=8.39, p=0.04). The following extrinsic risk factors contributed to AKP significantly: training load (p=0.04, Odds ratio [OR]=1.23); warm-up (p=0.04, OR=1.23); shoe condition (p=0.04, OR=0.14) and running surface (p=0.05, OR=1.2).  Discussion & conclusions: A substantial presence of AKP and its extrinsic risk factors were found among participants. These outcomes suggest that extrinsic risk factors should also be considered when managing AKP among runners. Keywords: Patellofemoral pain, external risk factors, athletes, poor resourced communities.

Clinical imaging in patellofemoral disorders is fundamental for the understanding of the pathology, and to find the adequate treatment option. Anatomical risk factors such as trochlear dysplasia, patella alta, lateralized tibiale tubercle (measured by the tibiale tubercle trochlear groove distance), torsional or coronal lower limb alignment that are the origine of patellar maltracking or even patellar dislocation, can be assessed with high reliability on conventional radiographs combined with MR imaging. The conservative and surgical treatment will highly rely on these findings. The importance of clinical imaging in unspecific anterior knee pain is less clear. It is mostly performed to exclude structural injuries, however is rarely reliable to diagnose the painful structure. Critical appraisal of morphological risk factors is necessary especially in the treatment of anterior knee pain, since fortuitous pathological findings are frequent.
