“…Compared with CTRL individuals, lower magnitude HCF in those with symptomatic FAI has already been reported during gait (Ng et al, 2018b;Catelli et al, 2019b) and squat (Catelli et al, 2020). Our results showed that the ACM individuals also show significantly higher posterior HCF during both phases of the squat (descent and ascent) compared with their symptomatic peers, and resembling CTRL outputs.…”

“…It is hypothesized that the ACM kinematics, kinetics, and muscle forces outputs will resemble the CTRL levels, instead of the FAI. However, based on analysis of different tasks (Ng et al, 2018b;Catelli et al, 2019bCatelli et al, , 2020Catelli et al, , 2021, we expect the CTRL will still produce higher HCF compared to the other groups.…”

“…The cam-type hip morphology is defined by an aspherical femoral head-neck that produces elevated alpha angles and decreased anterior head-neck offsets (Nötzli et al, 2002), and can result in anterior hip or groin pain, labral tears, and damage to the acetabular articular cartilage (Ito et al, 2001;Gosvig et al, 2008;Bowman et al, 2010;Speirs et al, 2013). Previous studies on FAI pathomechanism have speculated the existence of the cam-type morphology as causative to limit the functional range of motion (ROM), which has been shown in patients with cam-type FAI who demonstrated less hip and pelvic ROM during gait (Kennedy et al, 2009;Rylander et al, 2011;Brisson et al, 2013;Diamond et al, 2016;Ng et al, 2018b;Catelli et al, 2019b;Savage et al, 2021), deep squat (Lamontagne et al, 2009(Lamontagne et al, , 2011Ng et al, 2015;Bagwell et al, 2016;Catelli et al, 2019aCatelli et al, , 2020, stairs (Rylander et al, 2013;Diamond et al, 2018;Catelli et al, 2019aCatelli et al, , 2021, and clinical assessments (Kapron et al, 2012;Ng et al, 2016). Recent in silico analyses have demonstrated reduced hip contact forces (HCFs) compared to matched healthy individuals while performing different tasks (Catelli et al, 2019b(Catelli et al, , 2020(Catelli et al, , 2021.…”

Cam morphology is defined as an aspherical femoral head-neck junction that causes abnormal contact of the acetabular rim with the anterior hip. Imaging confirmation of the cam morphology, associated with clinical signs and pain in the hip or groin, is characterized as femoroacetabular impingement (FAI) syndrome. Although some individuals with cam morphology do not experience any symptoms, sparse studies have been done on these individuals. Understanding the way asymptomatic individuals generate muscle forces may help us to better explain the progression of the degenerative FAI process and discover better ways in preventing the onset or worsening of symptoms. The purpose of this study was to compare the muscle and hip contact forces of asymptomatic cam morphology (ACM) and FAI syndrome men compared to cam-free healthy controls during a deep squat task. This prospective study compared 39 participants, with 13 in each group (ACM, FAI, and control). Five deep squatting trials were performed at a self-selected pace while joint trajectories and ground reaction forces were recorded. A generic model was scaled for each participant, and inverse kinematics and inverse dynamics calculated joint angles and moments, respectively. Muscle and hip contact forces were estimated using static optimization. All variables were time normalized in percentage by the total squat cycle and both muscle forces and hip contact forces were normalized by body weight. Statistical non-parametric mapping analyses were used to compare the groups. The ACM group showed increased pelvic tilt and hip flexion angles compared to the FAI group during the descent and ascent phases of the squat cycle. Muscle forces were greater in the ACM and control groups, compared to the FAI group for the psoas and semimembranosus muscles. Biceps femoris muscle force was lower in the ACM group compared to the FAI group. The FAI group had lower posterior hip contact force compared to both the control and ACM groups. Muscle contraction strategy was different in the FAI group compared to the ACM and control groups, which caused different muscle force applications during hip extension. These results rebut the concept that mobility restrictions are solely caused by the presence of the cam morphology and propose evidence that symptoms and muscle contraction strategy can be the origin of the mobility restriction in male patients with FAI.

“…While a plethora of literature on the relationship between HJCF and movements, such as walking, running, and stair climbing exist (Heller et al, 2001 ; Bergmann et al, 2004 ; Lenaerts et al, 2008 ; Giarmatzis et al, 2015 , 2017 ; Wesseling et al, 2015 ; Meyer et al, 2018 ; Kainz et al, 2020 ), only sporadic research has been done regarding other activities, such as single-leg standing or cycling (Bergmann et al, 2001 ; Varady et al, 2015 ; Damm et al, 2017 ) and even less that have dealt with specific hip-strengthening exercises. Catelli et al ( 2020 ) compared HJCFs during a squat between patients with the cam-type femoroacetabular impingement for both pre- and post-hip-corrective surgeries and with those of a healthy control in which they found no significant difference. In vivo measurements via instrumented endoprosthesis showed that only weight-bearing exercises caused significantly high HJCF (up to 441% of the body weight), whereas most of the others, such as non-weight-bearing, isometric exercises, did not (Schwachmeyer et al, 2013 ).…”

An increase in hip joint contact forces (HJCFs) is one of the main contributing mechanical causes of hip joint pathologies, such as hip osteoarthritis, and its progression. The strengthening of the surrounding muscles of the joint is a way to increase joint stability, which results in the reduction of HJCF. Most of the exercise recommendations are based on expert opinions instead of evidence-based facts. This study aimed to quantify muscle forces and joint loading during rehabilitative exercises using an elastic resistance band (ERB). Hip exercise movements of 16 healthy volunteers were recorded using a three-dimensional motion capture system and two force plates. All exercises were performed without and with an ERB and two execution velocities. Hip joint kinematics, kinetics, muscle forces, and HJCF were calculated based on the musculoskeletal simulations in OpenSim. Time-normalized waveforms of the different exercise modalities were compared with each other and with reference values found during walking. The results showed that training with an ERB increases both target muscle forces and HJCF. Furthermore, the ERB reduced the hip joint range of motion during the exercises. The type of ERB used (soft vs. stiff ERB) and the execution velocity of the exercise had a minor impact on the peak muscle forces and HJCF. The velocity of exercise execution, however, had an influence on the total required muscle force. Performing hip exercises without an ERB resulted in similar or lower peak HJCF and lower muscle forces than those found during walking. Adding an ERB during hip exercises increased the peak muscle and HJCF but the values remained below those found during walking. Our workflow and findings can be used in conjunction with future studies to support exercise design.

Hips with developmental dysplasia (DDH) are at a heightened risk of premature hip osteoarthritis, which is often expedited by mechanically induced articular tissue damage. A prevalent form of damage in DDH is labral tears caused by abnormal loading at the shallow acetabular edge. Although the majority of reported DDH‐related labral tears occur in the antero‐superior acetabulum, posterior labral tears are prevalent in individuals whose lifestyle involves frequent high hip flexion tasks such as squatting. To better understand region‐specific risks for chondrolabral damage during high hip flexion, we used image‐based musculoskeletal models to compare acetabular edge loading (AEL) during double‐legged squat between hips with symptomatic DDH (n = 10) and healthy controls (n = 10). Compared to controls, hips with DDH had higher instantaneous posterior AEL at the lowest point of squat (2.6 vs. 1.8 ×BW, p ≤ 0.04), and higher accumulative loading across the duration of the squatting motion (2.6 vs. 1.9 ×BW*s, p ≤ 0.04). Elevated posterior AEL coincided with increased net hip extension moments and posterior joint reaction forces, and was correlated with the severity of DDH acetabular deformity. Our findings suggest that posterior AEL is elevated in hips with symptomatic DDH during double‐legged squat, which may contribute to chondrolabral damage in individuals who often perform such high hip flexion tasks. Clinical evaluation of DDH should consider patient‐specific anatomy and lifestyle factors when establishing diagnoses and planning personalized treatment.
