Ever feel like your knees are knocking together, causing discomfort or even hindering your athletic performance? You might be experiencing knee valgus, often referred to as "knock knees." While it can seem daunting, understanding the condition and implementing the right strategies can make a world of difference. Let's explore what knee valgus is and, more importantly, how to fix knee valgus and get you moving comfortably and confidently again.
Understanding Knee Valgus (Knock Knees)
Knee valgus, or "knock knees," is a condition where the knees angle inward and touch or come close to touching while the ankles remain apart. This alignment issue puts excessive stress on the inside of the knees, ankles, and hips, and can contribute to various problems. It's more common in children, often correcting itself as they grow. However, it can persist or develop in adulthood due to factors like muscle imbalances, poor posture, injuries, or underlying medical conditions.
Why Fixing Knee Valgus Matters
Leaving knee valgus unaddressed can lead to a cascade of issues. The uneven weight distribution increases stress on certain joints, which can cause pain and discomfort. Here's why fixing knee valgus is essential:
- Pain: Knee pain, hip pain, and ankle pain are common due to the abnormal stress.
- Increased Risk of Injury: Knock knees increase the risk of ACL tears, meniscus tears, and patellar dislocations.
- Arthritis: Over time, the uneven wear and tear can accelerate the development of osteoarthritis in the knees.
- Reduced Athletic Performance: Knee valgus can hinder athletic movements and reduce overall performance.
- Poor Posture: Knee valgus can contribute to a hunched over posture, which will further cause back and neck pain.
How To Fix Knee Valgus: A Step-by-Step Guide
Now, let's get into the actionable steps you can take to fix knee valgus. Keep in mind that consistency is key. These exercises and strategies require regular practice to see lasting improvements. If your knee valgus is severe or causing significant pain, consulting a physical therapist or other healthcare professional is highly recommended.
Step 1: Identify and Address the Root Cause
Before diving into exercises, it's crucial to understand the underlying cause of your knee valgus. Is it due to muscle imbalances, poor posture, or a structural issue? Consulting with a physical therapist will help with properly identifying the cause. Once identified, you can target the specific muscles and movement patterns that need correction.
Step 2: Strengthening Weak Muscles
Weakness in certain muscle groups is a common contributor to knee valgus. Strengthening these muscles helps realign the legs and stabilize the knees.
Gluteus Medius Strengthening
The gluteus medius is a crucial hip abductor that helps control the position of the knees. Weakness in this muscle can lead to your knees caving inward.
- Side-Lying Leg Lifts: Lie on your side with your legs straight. Slowly lift your top leg towards the ceiling, keeping your knee straight and foot pointed forward. Lower the leg slowly. Perform 15-20 repetitions on each side.
- Clamshells: Lie on your side with your knees bent and feet stacked. Keeping your feet together, open your top knee like a clamshell. Lower the knee slowly. Perform 15-20 repetitions on each side. You can add a resistance band around your thighs to increase the challenge.
- Hip Abduction with Resistance Band: Stand with a resistance band around your ankles. Step sideways, keeping your feet hip-width apart. Perform 15-20 repetitions in each direction.
Hip External Rotator Strengthening
These muscles help rotate the hip outward, which counters the inward rotation that contributes to knee valgus.
- Banded Hip External Rotation: Sit with a resistance band around your knees. Keeping your feet together, push your knees outward against the band. Hold for a few seconds, then slowly release. Perform 15-20 repetitions.
- Glute Bridges with Band: Lie on your back with your knees bent and feet flat on the floor. Place a resistance band around your thighs. Squeeze your glutes and lift your hips off the floor, keeping your back straight. Hold for a few seconds, then slowly lower. Perform 15-20 repetitions.
Vastus Medialis Obliquus (VMO) Strengthening
The VMO is part of your quadriceps muscle and plays a vital role in knee stability. Strengthening it can help improve knee alignment.
- Terminal Knee Extensions (TKEs): Attach a resistance band to a stable object at ankle height. Stand with the band around your lower thigh, just above your knee. Slightly bend your knee, and then straighten it fully, focusing on squeezing your VMO at the end of the movement. Perform 15-20 repetitions.
- Leg Extensions: Using a leg extension machine, extend your leg from a bent position to a straight position. Focus on controlled movement and squeeze your VMO at the top. Perform 10-15 repetitions with a light weight.
Step 3: Stretching Tight Muscles
Tight muscles can pull your knees out of alignment. Stretching these muscles improves flexibility and range of motion.
Adductor Stretching
Tight adductor muscles (inner thigh muscles) can contribute to knee valgus by pulling the knees inward.
- Groin Stretch (Butterfly Stretch): Sit on the floor with the soles of your feet together. Gently press your knees towards the floor. Hold for 30 seconds.
- Side Lunge Stretch: Step sideways into a lunge, keeping one leg straight and the other bent. You should feel a stretch in your inner thigh of the straight leg. Hold for 30 seconds, then switch sides.
Hip Flexor Stretching
Tight hip flexors can affect posture and contribute to muscle imbalances that lead to knee valgus.
- Kneeling Hip Flexor Stretch: Kneel on one knee with the other foot forward. Gently push your hips forward, feeling a stretch in the front of your hip. Hold for 30 seconds, then switch sides.
- Thomas Stretch: Lie on your back and bring one knee towards your chest. Let the other leg hang off the edge of the bed. You should feel a stretch in the front of your hip. Hold for 30 seconds, then switch sides.
Calf Stretching
Tight calf muscles can affect ankle mobility, which in turn can contribute to knee valgus.
- Gastrocnemius Stretch: Stand facing a wall and place one foot slightly behind the other. Lean towards the wall, keeping your back leg straight and heel on the ground. You should feel a stretch in your upper calf. Hold for 30 seconds, then switch sides.
- Soleus Stretch: Perform the same stretch as the gastrocnemius stretch, but bend your back knee. This targets the soleus muscle, which is located deeper in the calf. Hold for 30 seconds, then switch sides.
Step 4: Improving Posture and Body Awareness
Poor posture can exacerbate knee valgus. Consciously improving your posture and body awareness can make a significant difference.
- Stand Tall: Imagine a string pulling you up from the crown of your head. Keep your shoulders relaxed and your core engaged.
- Sit Properly: Sit with your feet flat on the floor and your back straight. Use a lumbar support if needed.
- Mirror Work: Practice your posture in front of a mirror to identify areas that need improvement.
Step 5: Proprioceptive Exercises
Proprioception is your body's awareness of its position in space. Improving proprioception helps your body maintain proper alignment and stability.
- Single-Leg Balance: Stand on one leg and try to maintain your balance. Start with your eyes open, and then progress to closing your eyes for an added challenge. Hold for 30 seconds on each leg.
- Wobble Board Exercises: Stand on a wobble board and try to maintain your balance. This helps improve your ankle and knee stability. Start with small, controlled movements and gradually increase the range of motion.
Step 6: Footwear Considerations
The shoes you wear can also influence your knee alignment. Supportive footwear with good arch support can help improve your lower body biomechanics.
- Arch Supports/Orthotics: If you have flat feet or overpronation, arch supports or custom orthotics can help correct your foot alignment and reduce knee valgus.
- Supportive Shoes: Choose shoes with good arch support and cushioning. Avoid shoes that are overly flexible or lack support.

Important Considerations When Working To Correct Knock Knees
While many cases of knee valgus can be addressed with exercise and lifestyle adjustments, it's crucial to be aware of certain situations that require professional medical attention. If you experience any of the following, it's essential to consult with a doctor or physical therapist:
- Severe Pain: If you experience intense or persistent knee pain that doesn't improve with rest or over-the-counter pain relievers.
- Sudden Injury: If your knee valgus is the result of a recent injury, such as a fall or sports-related incident.
- Limited Range of Motion: If you have difficulty bending or straightening your knee, or if your knee feels locked or unstable.
- Swelling or Inflammation: If your knee is visibly swollen, red, or warm to the touch.
- Underlying Medical Conditions: Certain medical conditions, such as arthritis or bone disorders, can contribute to knee valgus. In these cases, it's essential to address the underlying condition in addition to the knee valgus itself.
Addressing knee valgus takes time, effort, and consistency. By understanding the underlying causes and implementing a tailored approach that includes strengthening, stretching, posture correction, and proprioceptive exercises, you can make significant progress in improving your knee alignment and overall lower body health. Remember to listen to your body, be patient with yourself, and seek professional guidance when needed. You're on your way to healthier knees and a more active, pain-free lifestyle!
