Varus knee, also known as genu varum, is a condition that causes the legs to turn inward and the knees to face outward. It is relatively common in infants and toddlers and usually resolves itself as they grow older. In adults, varus knee can be caused by improper bone formation due to rickets, cancer, or arthritis. Certain exercises can help strengthen the muscles around the knee and minimize pain and discomfort caused by the condition. These include stretching and strengthening exercises, such as yoga, squats, and exercises that target the hip external rotator muscles. In severe cases, surgery may be required to realign the tibia and femur.

Hip external rotators
Varus knee is a condition that causes the legs to turn inward, resulting in bowlegs. It occurs when the tibia (shinbone) turns inward instead of aligning with the femur (thighbone), causing the knees to turn outward. While this condition is common in infants and toddlers, it usually resolves by the time children learn to walk. However, in older children and adults, varus knee is typically caused by improper bone formation due to rickets, cancer, or arthritis.
Exercises that strengthen the hip external rotator muscles have been proven to positively impact varus knee. The hip external rotators are a group of muscles that enable the thigh and knee to rotate outward, away from the body. These muscles are essential for maintaining stability during everyday movements such as stepping sideways or getting in and out of a car. They also play a crucial role in preventing injuries and reducing knee and lower back pain.
The gluteal muscles, including the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae, are essential for hip external rotation. The gluteus maximus, a large muscle in the buttocks, is the most powerful external rotator of the hip. The psoas major and iliacus muscles form the iliopsoas muscle, with the psoas major assisting in hip external rotation.
The lateral rotator group, consisting of six small muscles, also contributes to hip external rotation. These muscles include the piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris, and obturator externus. They originate from the hip bone and connect to the upper part of the femur. Additionally, the obturator externus is innervated by the lumbar plexus, while the other muscles in this group are innervated by the sacral plexus.
To strengthen the hip external rotators, various exercises and stretches can be performed. One such exercise involves standing with the feet shoulder-width apart and moving the left leg out to the side by 6 to 8 inches, followed by lifting the left foot off the ground by 1 to 2 inches. Yoga, squats, and specific hip stretches can also strengthen and improve the flexibility of the hip external rotators.

Hip abductors
Varus knee, also known as genu varum, is a condition that causes the legs to turn inward, resulting in a bow-legged appearance. While it is commonly observed in infants and toddlers, it usually resolves on its own before they turn two. In older children and adults, varus knee is often caused by improper bone formation due to rickets, cancer, or arthritis.
The hip abductors are responsible for most of the forces exerted on the hip while standing on one leg, which can be significantly greater than body weight. They stabilize the pelvis, preventing it from dropping or sagging excessively to one side during the stance phase of gait or single-limb stance. Additionally, they contribute to pelvic stabilization during walking and running, allowing for smooth abduction and rotation at the hip joint.
Weakness in the hip abductors can lead to insufficient pelvic stabilization, resulting in altered biomechanics and various issues in the kinetic chain. This can cause increased medial femoral rotation and valgus knee moments, leading to an increased Q-angle and subsequent patellar tracking issues. Furthermore, weakness in these muscles can contribute to knee pain, particularly in conditions like patellofemoral pain syndrome (PFPS) and iliotibial (IT) band syndrome.
To prevent and treat these issues, strengthening the hip abductors is essential. Hip abduction exercises such as lying side leg lifts, clamshells, banded side steps, and squats can improve hip abductor strength, enhance stability, and reduce pain associated with conditions like PFPS.

Quads
Varus knee, also known as genu varum, is a condition that causes the legs to turn inward, resulting in a bow-legged appearance. This occurs when the tibia (shinbone) turns inward instead of aligning with the femur (thighbone), causing the knees to angle outward. While many children outgrow this condition, some develop varus knee due to improper bone formation caused by rickets, cancer, or arthritis. In adults, varus knee can lead to osteoarthritis and cause pain, particularly during weight-bearing activities.
To prevent and treat varus knee, various exercises can be performed to strengthen the muscles around the knee and improve tibiofemoral alignment. Quadriceps, or quads, are a group of four muscles located in the front of the thigh that work together to extend the knee and stabilise the knee joint. Strong quads are crucial in maintaining proper knee alignment and preventing injuries.
One effective exercise for strengthening the quads is squats. To perform a basic squat, stand with your feet shoulder-width apart, look straight ahead, and extend your arms forward. Slowly bend both knees, keeping them aligned with your feet, and then straighten your legs to return to the starting position. It is important to maintain proper form throughout the exercise to avoid placing excessive stress on the knees.
Another exercise that targets the quads is the lunge. To perform a lunge, take a big step forward with one foot and lower your body towards the floor by bending both knees at a 90-degree angle. Ensure that your front knee is aligned with your second toe and does not extend beyond your toes. Push off your front foot to return to the starting position and repeat with the other leg. Lunges help improve balance and strengthen the muscles supporting the knee joint.
Additionally, neuromuscular exercises that focus on the lower limb muscles, including the quads, can be beneficial for varus knee. These exercises aim to improve the position and movement of the trunk and lower limb joints, enhancing dynamic stability and muscle activation patterns. By practicing more neutral knee positioning during specified exercises, individuals can improve control of their knee and hip muscles, reducing the risk of injury and improving overall function.
In summary, strengthening the quadriceps muscles through exercises like squats, lunges, and neuromuscular training can help prevent and manage varus knee. These exercises improve knee stability, alignment, and overall function, reducing pain and the risk of further complications. It is important to consult with a healthcare professional or physiotherapist to determine the most appropriate exercise program for your specific needs and to ensure proper form during exercises.

Hamstrings
Varus knee, also known as genu varum, is a condition that causes the legs to turn inward and the knees to face outward. It is caused by the tibia (shinbone) turning inward instead of aligning with the femur (thighbone). While varus knee is common in infants and toddlers, it usually resolves on its own before they turn two years old. In older children and adults, varus knee is usually caused by improper bone formation due to rickets, cancer, or arthritis. Certain professions can also increase the risk of developing varus knee.
To prevent and treat varus knee, physical therapy and weight training can help strengthen the muscles surrounding the leg bones. Exercises such as squats and yoga poses can improve mobility, flexibility, and muscle strength. In more severe cases, surgery may be required to realign the tibia and relieve pressure on the knee.
The hamstrings are crucial muscles located at the back of the thigh that play a significant role in knee stability and movement. They are responsible for hip extension, knee flexion, and leg rotation. Strong hamstrings are essential for maintaining proper knee alignment and preventing injuries.
To prevent knee varus and maintain healthy hamstrings, here are some recommended exercises:
- Squats: Stand with your feet shoulder-width apart, look straight ahead, and slowly bend both knees while keeping your knees aligned with your feet. Ensure your knees do not extend beyond your toes.
- Yoga: Practise yoga poses that focus on strengthening and stretching the muscles around the knees and hips. Yoga improves mobility, flexibility, and muscle strength.
- Hamstring stretches: Stand with your feet hip-width apart and bend one knee slightly. Reach for your toes and feel the stretch in the back of your leg. Hold for 30 seconds and repeat on the other side.
- Leg curls: Lie on your back and bend one knee, keeping your foot flat on the ground. Slowly lower your leg until you feel a stretch in the back of your thigh. Hold for a few seconds and repeat on each side.
- Bridge pose: Lie on your back with your knees bent and feet flat on the ground. Lift your hips towards the ceiling, squeezing your hamstrings. Hold for a few seconds and lower back down.
By incorporating these exercises into your routine, you can help prevent knee varus by strengthening and stretching your hamstrings. Remember to always consult with a healthcare professional or a physiotherapist before starting any new exercise routine, especially if you are experiencing knee pain or other symptoms.

Stretching and strengthening exercises
Varus knee, also known as genu varum, is a condition that causes the legs to turn inward, resulting in bow-leggedness. It occurs when the tibia (shinbone) turns inward instead of aligning with the femur (thighbone), causing the knees to turn outward. While this condition often resolves itself in young children, it can persist or develop in adults due to improper bone formation caused by rickets, cancer, or arthritis. Certain professions can also increase the risk of developing varus knee.
To prevent and manage varus knee, stretching and strengthening exercises are recommended. Here are some specific exercises that can help:
Stretching Exercises:
- Stand near a wall or door and lift your right leg, keeping your knee slightly bent. Place your heel on the wall and slowly extend your leg until you feel a stretch in your hamstring. Hold this position for 10 seconds, work for 30 seconds, and then repeat with the other leg. As your flexibility increases, move closer to the wall for a deeper stretch.
- Stand facing forward with your feet shoulder-width apart. Move your left leg out to your side approximately six to eight inches, and then lift your left foot off the ground one to two inches. Slowly bend your right knee about 10 degrees and hold this position for 45-60 seconds, feeling the stretch in your left hip. Repeat on the right side.
Strengthening Exercises:
- Squats are an excellent exercise for leg muscle therapy and strengthening the entire lower body. Stand with your feet shoulder-width apart, look straight ahead, and put your arms straight in front of you. Slowly bend both knees evenly, keeping your knees aligned with your feet. Then, straighten your legs.
- Exercises that strengthen the hip external rotator muscles can improve hip flexibility and reduce lower back pain associated with poor leg alignment. Stand facing forward with your feet shoulder-width apart. Move your left leg out to your side approximately six to eight inches, and then lift your left foot off the ground one to two inches.
In addition to these specific exercises, yoga is recommended for improving mobility and flexibility, which can help with genu varum. Swimming, cycling, rowing, pilates, and tai chi are also suggested as suitable forms of exercise for varus knee. It is important to consult with a doctor or medical professional to determine the appropriate exercise program for your specific needs and condition.
