There are some reports that increased adductor muscle activity may be related to the display of
knee valgus during certain movements, including bilateral squats (Padua et al. 2012) and unilateral squats (Mauntel et al. 2013).
Healthy dorsiflexion improves quad activation and helps keep the knee from
valgus collapse, or diving inward.
Female athletes have wider hips, putting a higher
valgus stress angle on their knees (knees inward), a stress that is the major factor of most non-contact ACL injuries.
However, the contribution of gluteus maximus force production and neuromuscular activity to knee
valgus during normal movement remains unclear.
Tighten Your Buns: Glute Bridges or Hip Thrusts One of the most common issues people have with squatting is known
as valgus collapse, or the knees collapsing inwards during the «up» phase of the exercise.
● Increased curvatures of the spine are usually due to slightly pronated or
valgus feet.
For the prevention of
hallux valgus using shoes that separates each toe of your foot.
MYTH Anatomical abnormalities of the lower body such as flat feet or knee
valgus make people more susceptible to running injuries.
Importantly in this regard, Homan et al. (2013) found that knee
valgus motion did not differ between groups with high and low hip abduction and hip external rotation strength.
An angular limb deformity, also called premature closure of a growth plate, radius curvus or
carpus valgus, is an abnormally shaped or crooked leg caused by stunted growth of one of the two long bones in a dog's front leg.
Someone who squats
with valgus knees (knees which collapse inwards on the ascent on squat) are likely to suffer from an imbalance in their hips or glutes, which could also show in how they stand, walk or run.
The most common reasons for knee
valgus include insufficient ankle dorsiflexion range of motion, poor hip mobility, poor gluteal strength and development and muscle poor coordination in the lower body in general.
It is in the absence of adequate hip extension and weak VMO that the «dreaded»
valgus occurs.
Gluteus medius: A key player is stabilizing your hips, the gluteus medius abducts, or brings your leg out to the side and helps prevent your knee from dipping in,
termed valgus collapse.
When the knee is bent to 30 degrees and an outward force applied to the lower leg to stress the medial ligament, pain is felt but there is no joint laxity (
play valgus stress test video).
Moreover, Lloyd and Buchanan (2001) noted that the gracilis does possess a muscle moment arm that is supportive of knee
valgus moments during knee extension movements.
Of particular note is the trial by Lubahn et al. (2011), which reported that adding a lateromedial (outward) force during the single - leg squat directed to increase knee
valgus actually decreases the muscle activity of the gluteus medius.

Tarsal plantigrade collapse,
tarsal valgus, tarsal varus, post-op arthrodesis, and neurological presentations are common orthopedic injuries that can affect your pet's ankle joint and cause pain and lameness.
These include tight extensor and adductor muscles and ligaments, poor muscle tone or development, atrophy or dystrophy, transitional vertebrae, high - calorie diet and rapid growth rate, excessive activity before skeletal maturity, anteversion or
valgus deformity, poor positioning on the radiography table, narrow pelvis, and possibly (though not likely) estrus.
While
carpal valgus (turning out at the pasterns) and external rotation of the foot are «acceptable» within the descriptions of «breed type», the occasional or perhaps frequent abnormalities of the ligaments and joints in the elbow that accompany this should be avoided or treated.
The inward collapse of the knees, also referred to
as valgus collapse and medial knee displacement, is a very common sight in the weight room.
Big things that leads to ME is repeated flexion, pronation (from palm up to palm down), and
valgus stress to the elbow (upper arm does not move and the forearm moves away from the body).
A good clean until the catch, and then legs split apart and stagger, there's
valgus collapse on one leg, and the lifter takes a few steps to stabilize himself and get the hips underneath the bar.
Anatomical abnormalities of the lower body such as flat feet or knee
valgus make people more susceptible to running injuries.
Carpal hyperextension,
carpus valgus, carpus varus, post-op arthrodesis, and neurological presentations are common orthopedic injuries that can affect your pet's wrist joint and cause pain and lameness.
They observed that lower levels of gluteus maximus EMG amplitude that predicted reduced
knee valgus.
Shoes interfere with this natural process and can promote plantar fasciitis, hallux
valgus, bunions, ingrown toenails, corns, and Morton's neuroma.
Generally speaking, lifters who squat narrow keep their feet pointed forward and lifters who squat with a wider stance tend to flare their feet slightly, thereby allowing for a greater hip involvement and reducing the risk of knee
valgus.
Another great way to correct
the valgus knee collapse is the plate squat.
Knee
valgus, otherwise known as knee caving, is one of the most common squatting mistakes beginners and advanced lifters do.
This is essentially the complete opposite action to that seen during the typical ACL tear (
the valgus position described above).
Thus, the client with knee
valgus may have short and overactive adductors that internally rotate the are working pull the femur and subsequently pull on the piriformis
Yes, the vastus medialis does stabilize the knee but it helps resist
a valgus stress / strain on the knee.
Proper squat form requires your knees to grow slightly further apart as you lower your body, rather than collapse inward (
valgus knee position).
That's called knee
valgus, or medial knee displacement.
Soft surfaces — such as sand and grass, requires more stability and challenges pronation, inward collapsing of the knees (
valgus) and base of support.
The most common compensations seen in those with a hip internal rotation deficit (HIRD) include overpronation at the feet, a knee
valgus, reduced step length, external rotation of the foot toward terminal stance phase and increased lumbar and knee extension.
If you learn to squat, or deadlift, properly without form issues such as
valgus knees or hip impingement your general movement will be better and you will be more able to build strength in the vital areas surrounding the posterior chain (in this example).
Of course, I couldn't leave out another common HUGE mistake — > Knees Caving /
Valgus Collapse!
The caveat is only if you perform them properly - not with the eye watering knee
valgus and lack of hip extension that the typical player performs the lifts with that more resembles a sumo squat - reverse curl combo.
DO NT DO: ❌ Knees Caving /
Valgus Collapse — super common when squatting with an anterior pelvic tilt & heels lifted, especially when coming out of the hole.
Is the client better able to prevent their knee from collapsing inward (
valgus) during a lunge (assessing knee stability)?
If an individual has arches that are collapsed inward, which is known as
a valgus foot, this could cause the leg bones to rotate inwards in such a manner as to create increased curves in the lower back and upper back and promoting rounded shoulders.
Additionally, assessment of movement quality is also routinely carried out in simpler ways within sports medicine, such as where measurements of knee
valgus or lumbar movement are carried out.
Excessive knee
valgus has been linked to gluteus medius weakness, by way of reduced hip abduction strength (Jacobs et al. 2007; see review by Cashman, 2012).
Knee
valgus is thought to be an important predictor of anterior cruciate ligament injury, particularly in females (Hewett et al. 2005).
