Background: Floorball is one of the most popular team ball sports in Northern Europe, particularly among youths. The injury incidence is high, as is the case in other pivoting youth team ball sports, such as football. The injury prevention exercise programme (IPEP) Knee Control is developed to reduce injuries in team ball sports. Though, programme effects and implementation factors in floorball has not been evaluated.The overall aim of this thesis was to evaluate the effects of the Knee Control IPEP and explore players' and coaches' experiences of using Knee Control in youth floorball. Methods:Study A was a cluster-randomised controlled trial (RCT) evaluating the effects of Knee Control in reducing floorball injuries. The RCT comprised of 48 clusters (clubs) with male and female floorball players (12-17 years) on the community level who were randomised into either an intervention or control group. Seventeen clusters (31 teams with 301 players) in the intervention group and 12 clusters (16 teams with 170 players) in the control group were included for analyses. During a pre-season implementation workshop, the intervention group coaches were instructed to use Knee Control and a standard running warm-up before every training session during the season. Control teams continued usual training. Teams were followed during a competitive season (26 weeks). Player exposure to floorball and occurrence of acute and gradual onset injuries were reported weekly via a web-based player survey using the Oslo Sports Trauma Research Centre overuse injury questionnaire. Team and player compliance to Knee Control was reported monthly by coaches. Players were divided into three compliance groups based on their average weekly number of Knee Control sessions: high (≥2 sessions), intermediate (≥1 to <2 sessions), and low dose (<1 session). Additionally, players and coaches in the intervention group answered a post-season survey on experiences using Knee Control.Study B was a qualitative study exploring facilitators and barriers of Knee Control use and how to overcome the barriers. Semi-structured focus group discussions, six with players (11-17 years old, n =42), and two with coaches (n =12) were conducted. Results:In Study A, the intervention group had a 35% lower incidence rate of injuries overall (adjusted incidence rate ratio (IRR), 0.65; 95% confidence interval (CI), 0.52-0.81) and 45% lower incidence of acute injuries (adjusted IRR, 0.55; 95% CI, 0.37-0.83) than the control group. There was no difference in the prevalence of gradual onset injuries. Male players in the high dose group had consistently lower injury incidence and prevalence compared to the low dose group, while no differences between the three compliance groups were seen in female players. Common facilitators of Knee Control use among coaches were support and education for coaches and high player motivation, and common barriers were that injury prevention training was time-consuming, a lack of space to execute the exercises, and a lack of player motivation. Players and ...

“… 1 , 2 , 3 , 4 It typically occurs due to gradual-onset knee disorders, defined as injuries that lack a definable sudden or precipitating inciting event. 5 Examples of gradual-onset knee disorders are knee osteoarthritis (OA), patellofemoral pain (PFP), chondromalacia patellae (CMP), and patellar tendinopathy (PT). Knee OA is frequent in older individuals, affecting 263 million individuals worldwide.…”

“…The patellar tendon is a common source of pain in young active individuals. 1,2 The central third of the patellar tendon is also commonly used as an autograft for anterior cruciate ligament reconstruction (ACLR) 3 especially among athletes. 4 After this surgery there is also a high rate of pain in the region of the patellar tendon.…”

Patellar tendons are assumed to be uniform in morphology and mechanical properties despite a higher prevalence of tendinopathies observed in the medial region. The purpose of this study was to compare the thickness, length, viscosity, and shear modulus of the medial, central, and lateral regions of healthy patellar tendons of young males and females in vivo. B‐mode ultrasound and continuous shear wave elastography were performed on 35 patellar tendons (17 females, 18 males) over three regions of interest. A linear mixed‐effects model (α = 0.05) was used to determine differences between the three regions and sexes followed by pairwise comparisons for significant findings. The lateral region (mean [95% confidence interval] = 0.34 [0.31–0.37] cm) was thinner compared with the medial (0.41 [0.39–0.44] cm, p < 0.001), and central (0.41 [0.39–0.44] cm, p < 0.001) regions regardless of sex. Viscosity was lower in the lateral (19.8 [16.9–22.7] Pa‐s) versus medial region (27.4 [24.7–30.2] Pa‐s, p = 0.001). Length had a region‐by‐sex interaction (p = 0.003) characterized by a longer lateral (4.83 [4.54–5.13] cm) versus medial (4.42 [4.12–4.72] cm) region in males (p < 0.001), but not females (p = 0.992). Shear modulus was uniform between regions and sexes. The thinner, and less viscous lateral patellar tendon may reflect the lower load the tendon experiences explaining the differences in regional prevalence of developing tendon pathology. Statement of Clinical Significance: Healthy patellar tendons are not uniform in morphology or mechanical properties. Considering regional tendon properties may help guide targeted interventions for patellar tendon pathologies.
