What Causes Weak Knees
Weak Quadriceps
The quads and, most importantly, the vastus medialis obliques , are the muscles that run along the front and side of the leg and attach to the knee.
These are super important for keeping the knee straight and absorbing shock from running and other weight-bearing activities. A weakness here will lead to an unstable knee and increased pressure on the knee joint a big ouch factor!
When it comes to exercises to strengthen knees, working the quads and VMO are key.
Weak Glutes
While you might be shaking your head and thinking, What does my butt have to do with my knees? the importance of the glute-knee connection may surprise you.
You see, the glute muscles are key players in hip adduction and abduction . Since they create this movement, theyre also able to resist it when necessary. Say, for example, when youre jogging the last thing you want is your hips and knees rotating the wrong way at the wrong time.
This is exactly what happens when you have weak glutes. And most of us have weak glutes because we sit so much and dont activate our glutes properly.
As a result, our knees are not supported by the glute muscles during exercise, which can lead to improper foot landing and rotations. In turn, you get a ton of shock and pressure on your knee joints instead of your glute muscles, where it could be absorbed efficiently.
Lesson: give your booty the attention it deserves!

Can Muscle Problems Cause Pain
Yes, problems in the knee muscles do cause pain! Tightness or weakness in the quadriceps, hamstrings and other muscles around the knee are often part of the cause of knee pain.
If there is muscle imbalance, it changes the way the forces go through the knee, and puts extra pressure on certain areas, leading to knee pain.
Knee muscles are also often injured. It may be that they are overstretched and tear, or that they are overused and become inflamed.
Common injuries associated with the knee muscles include:

Exercising With A Physical Therapist
Physical therapy is often part of treatment for arthritis and other joint problems. A physical therapist individualizes your treatment program to restore or maintain your physical functioning and carries out specific instructions from your orthopedist.
First, the therapist thoroughly evaluates your pain, functional ability, strength, and endurance. A physical therapy session may involve pain-relieving treatments using ice, heat, massage, or other approaches. The physical therapist supervises you in doing exercises and teaches you exercises you can do at home. Depending on the therapy center, there may be a pool and a variety of exercise equipment to use.
Gait retraining. Knee and hip problems can disrupt your normal walk by causing pain, restricting joint movement, or weakening muscles. A person’s usual pattern of standing, walking, or running may also invite joint problems if weakness in key muscles, poor coaching advice, or bad habits throw off the gait.
It may take many years of walking with an abnormal gait before joint injury occurs. Improper running leads to pain and injury more rapidly because it involves greater force with each stride.
If you have had a knee or hip replacement, gait retraining helps you relearn to stand up straight and use both legs evenly. Gait retraining may begin in the pool, where the water’s buoyancy takes weight off the joint, makes it easier to stand up straight, and reduces the fear of falling.
To Get Better Results
If you have healthy knees, aim for 2-3 sets of 8-12 reps of each exercise. If you havent worked out in a while, start with one set and build up from there.
If you have osteoarthritis, try to do these exercises 3-5 times per week for 8-12 weeks. Studies suggest this can help you manage the knee pain and improve your knee function.
Also:
- Stop doing these exercises if theyre painful or you feel a sharp pain in your knees.
- Dont push through the pain or you risk getting injured.
- Mild swelling is common, mostly if you havent exercised in a while. Too much swelling is a sign that you might be doing too much or theres an injury.
- Reduce the number of sets or repetitions if you have too much muscle soreness afterward.
- Combine these exercises with good sleep and nutrition habits for best results.
If you arent sure whether you can do these exercises or not, consult with a physical therapist first.

Knee Strengthening Exercises That Prevent Injury
Posted on
According to the results of a 2011 Gallup poll, more than 25 percent of Americans deal with chronic knee or leg pain. Common causes of pain include previous injury, muscle imbalance, overuse, underuse or limited mobility. Individual cases vary, but strengthening exercises can often alleviate or even cure knee pain.
General knee strengthening exercises build surrounding muscles like quadriceps, hamstrings, gluteus and calves to improve joint stability and support. See a physician for recommendations on knee exercises specific to your condition, and if you find that a particular exercise hurts, stop and try another. Aim for three sets of 10 repetitions of each exercise.
1. Squats
Squats strengthen your quadriceps, glutes and hamstrings. If your knees are unstable, stand in front of a chair while you do squats so that you can sit if you lose your balance.
Stand with your feet shoulder-width apart. While keeping your back straight, sit back and down as far as you can comfortably go without letting your knees extend past your toes. Pause briefly and stand back up. Start with quarter or half squats and build up to full squats as you grow stronger.
2. Sit to Stand
This functional exercise is just what it sounds like: sit down slowly in a chair, then slowly rise to a standing position again.
3. Lunges
Forward lunges is also a great addition to these existing knee strengthening exercises. This exercise will strengthen your thighs and hips and also improve balance.

What Can You Do For The Pain
Your plan will depend on your specific injury. Mild to moderate issues will often get better on their own. To speed the healing, you can:
- Rest your knee. Take a few days off from intense activity.
- Ice it to curb pain and swelling. Do it for 15 to 20 minutes every 3 to 4 hours. Keep doing it for 2 to 3 days or until the pain is gone.
- Compress your knee. Use an elastic bandage, straps, or sleeves to wrap the joint. It will keep down swelling or add support.
- Elevate your knee with a pillow under your heel when you’re sitting or lying down to cut down on swelling.
- Take anti-inflammatorymedications. Nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen will help with pain and swelling. Follow the instructions on the label. These drugs can have side effects, so you should only use them now and then unless your doctor says otherwise.
- Practice stretching and strengthening exercises if your doctor recommends them. You may want to do physical therapy, too.
Make an appointment with a doctor if you still have pain after 2 weeks of home treatment, if the knee becomes warm, or if you have fever along with a painful, swollen knee.
Some people with knee pain need more help. For instance, if you have bursitis, your doctor may need to draw out extra fluid from the bursa in your knee. If you have arthritis, you may need an occasional corticosteroid shot to settle down inflammation. And if you have a torn ligament or certain knee injuries, you may need surgery.
Exercise And Knee Pain
If your knee pain is due to an injury, surgery, or arthritis, gentle stretching and strengthening exercises may help ease the pain while also improving your flexibility and range of motion.
Exercising a knee thats injured or arthritic may seem counterintuitive, but in fact, exercise is better for your knee than keeping it still. Not moving your knee can cause it to stiffen, and this may worsen the pain and make it harder to go about your daily activities.
Gentle stretching and strengthening exercises can strengthen the muscles that support your knee joint. Having stronger muscles can reduce the impact and stress on your knee, and help your knee joint move more easily.
Before you start an exercise program for knee pain, be sure to talk to your doctor or physical therapist to make sure the exercises are safe for you. Depending on your situation, they may recommend some modifications.

These are common among athletes. There are two types of ligaments: collateral and cruciate. You have four main ligaments in your knee: the lateral collateral ligament, medial collateral ligament , posterior cruciate ligament, and anterior cruciate ligament .
Ligaments help keep the bones in your knee stable, but they are prone to injuries, particularly through contact or from changing direction suddenly when youâre running. Sports fans know that ACL and MCL injuries can sideline an athlete for months.
But for most people who donât make their living running full speed or getting hit, it usually takes several weeks to recover.
