Why Does My Knee Hurt When I Straighten It

Why My Knee Hurts When I Bend It And Straighten It

Why can’t I straighten my knee?

Sometimes I wonder why my knee hurts when I bend it and straighten it. Many people say that this condition usually occurs in people who are sedentary, or who spends most of their time seated. However, I live an active lifestyle so the reason as to why my knee hurts when I bend it and straighten it, still remains a mystery to me. This condition bothered me so much, but not enough to convince me to go and see a doctor. So, I decided to research online and found out a variety of reasons that could possibly explain why my knee hurts when I bend it and straighten it.

Among the various reasons I found online, what intrigued me was the so-called Runners knee. Its a condition that commonly affects runners or athletes, as its name suggests. However, this condition can also affect ordinary people. Whenever you have a runners knee, it makes you have difficulty in walking, sitting, standing, and even bending your knee. This condition will surely make you feel frustrated, especially if you are fond of doing the said activities.

If You Feel A Popping Or Cracking Sensation Behind Your Kneecap:

If this sensation occurs during a knee injury – you most likely tore your meniscus. The meniscus is a piece of cartilage in your knee that cushions and stabilizes the joint. This type of tear is very common in contact sports like football and non-contact sports that require jumping and cutting like volleyball. Other symptoms include pain in the knee, swelling, difficulty bending your knee, pain behind your knee when straightening your leg, or a tendency for your knee to lock or get stuck.

Potential Reasons Your Knee Hurts When Straight But Not When Bent

When you have knee pain when your leg is straight, it is usually related to one of the following:

  • Patellofemoral pain syndrome More commonly known as runners knee, this condition develops when the kneecap shifts out of its natural position. This can occur as the result of misalignment of the patellar groove, which is the track of tendons that keep the kneecap in its right place. Tension or weakness in the tendons can cause the misalignment, or it may be the result of a traumatic injury.When you have runners knee, it can be difficult to straighten the knee without pain.
  • Patellar tendinitis More commonly known as jumpers knee, this condition is the result of irritation and inflammation along the patellar tendon. The patellar tendon connects the bottom of your kneecap to the top of your shinbone. Frequent physical activities, especially those that involve jumping, can exert great amounts of force on the knee, which causes pain when trying to straighten the knee.

If you suspect you have knee pain from one of these conditions, please dont hesitate to reach out to a health care professional for assistance.;

Luckily, there are knee pain remedies that you can apply to lessen the pain, or totally get rid of it. Here are some of the things that I do every time my knee hurts when I bend it and straighten it:

  • Epsom Salt Soak
  • Epsom salt is surprisingly effective when it comes to treating knee pain. Epsom salt contains magnesium sulphate that acts as a pain reliever. To relieve your knee pain, soak it in a mixture of ½ cup Epsom Salt and warm water. If a large bowl isnt enough, fill your tub with water and pour in some Epsom salt in it.

  • Apple Cider Vinegar
  • If you dont have Epsom salt at home, then you can also use an alternative home remedy in the form of apple cider vinegar. Soak your knees in a mixture of warm water and apple cider vinegar. If you think soaking your knee in the mixture is too much, then you can just apply the mixture on your knee directly.

    You Notice An Obvious Deformity

    If you notice your knee jutting outward in a way it never has before, take note. A dislocated or fractured patella can cause injuries like this, explains Brian Schwabe, C.S.C.S., board-certified sports physical therapist based in Los Angeles.

    While some deformities occur over time, when the deformity is a result of an injury, it could be the result of a fracture or chronic wear on the knee joint. If you are already experiencing any kind of misalignment in your lower extremities, then you could be more prone to this type of injury.

    If you notice a bone deformity after an injury, he recommends seeking the assistance of an orthopedic doctor immediately.;The doctor will likely take x-rays as well as perform a visual diagnosis to determine if you need surgery.

    Five Common Reasons For Inside Knee Pain

    Pain on the inside of the knee can happen to anyone, whether youre a runner, footballer or casual gym-goer. Today, physiotherapist Matt looks in detail at five of the most common causes of medial knee pain. He also shares tips on how to avoid a knee injury and what to do if you it happens to you.

    Medial Collateral Ligament Strain

    The MCL is one of the four major ligaments of the knee. The others are the ACL , PCL and LCL . The role of these ligaments is to maintain the stability of the knee joint and prevent forces from moving the thigh and shin bones apart. The MCL runs vertically along the inside of the knee; from the thigh bone , across the knee joint to the shin bone . Ligament injuries often occur due to an obvious mechanism of injury, such as a twist or a force hitting the outside of the knee . Dependent on the severity of the injury, there may be swelling, bruising and pain on the inside of the knee. You may also experience difficulty walking and a feeling of instability in the knee.

    Malpositioning Of The Implants

    Surgeons make an effort to balance the knee at the time of surgery. This means finding the proper size and alignment of the knee replacement so that the knee joint is not too tight, and not too loose, and so this balancing is the same with the knee straight and bent.

    This is precisely why a knee replacement is a difficult procedure, and the art of perfecting this takes many years. Errors in the positioning of an implant may not be apparent on the operating table and only become evident when the recovery is stalled.

    Newer patient-specific knee replacements are tailor-made and may reduce the risk of malpositioning.

    How Did You Hurt Your Knee

    Why do your knees hurt?

    Traumatic injuriesare noticeable right away and worsen dramatically the next day as pain and inflammation set in. traumatic injuries typically occur playing sports, during slips, falls, and other work-related accidents. The trauma is caused by the injury exceeding the tolerance of knee structures leading to breaks, ruptures or tears.

    Knee ligaments, bones, and menisci are the most commonly damaged structures in the knee joint. Injuries to bone and connective tissue result in long term pain and will impede normal knee function for some time after the initial injury. Less serious traumatic injuries may result in only painful, superficial contusions which heal relatively quickly. If you believe you have incurred serious knee trauma you should visit a doctor as soon as possible. If bone or connective tissue within your joint is damaged a surgical assessment could be required.

    Overuse injuriestypically cause knee pain that comes and goes and varies in intensity. Sometimes our favorite activities subject our knees to stressful movement patterns repetitively. Think jumping, squatting, kneeling, running, lunging type movements. Moving in this way over and over again can irritate knee structures such as bursae, tendons, and articular cartilage.

    Degenerative Joint Disease is the number one cause of long term disability relating to knee pain. Pain often comes on slowly and over time those affected by arthritis will experience constant pain while performing weight-bearing activities.

    Knee Injury: 6 Things To 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.
  • 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.

    Your Knee Keeps Buckling

    When you got hurt, did it feel like your knee gave way underneath you? Were not talking about a temporary sensation of weakness or some wobbliness, but more like your shin and thigh bone werent connecting or staying in place. A buckling knee could signal an ACL tear or a cruciate ligament injury.

    It could start with a small pop or crack, or you could feel it after a strenuous exercise session or a soccer game.

    Either way, your knee feels unstable or weak. Your knee may give out momentarily, which is scary because you might not trust yourself to walk safely when this happens. According to Dr. Howard Luks, an orthopedic surgeon, this could indicate a tear in the patella or the quadriceps tendon.

    These tendons are on the front of your knees and offer a lot of support to keep you upright. If theyre not in top form, youre bound to feel weak in the knees , and you might not be able to walk at all. If this is the case, you could need surgery.

    On the other hand, the weakness could be temporary, caused by wear and tear, improper footwear, or a strain. If youre a weekend warrior or youre over the age of 30 , you might experience this symptom on a regular basis.

    However, if the weakness is recurring and happens every time you exercise, its possible you have a time bomb thats waiting to happen. When in doubt, seek advice from a physician.

    If your knee buckles under you when you are walking, then it usually indicates instability, she says.

    Chondromalacia: What Makes Knee Pain Worse

    Medical Author: Melissa Conrad Stöppler, MDMedical Editor:Barbara K. Hecht, PhD

    Chondromalacia, technically termed chondromalacia patellae, is the most common cause of chronic knee pain. The condition develops due to softening of the cartilage beneath the knee cap , resulting in small areas of breakdown and pain around the knee. Instead of gliding smoothly over the knee, the knee cap rubs against the thigh bone when the knee moves. The changes can range from mild to complete erosion of the cartilage. This process is sometimes referred to as the patellofemoral syndrome.

    Chondromalacia commonly occurs in females. Girls in their teens are at elevated risk because the cartilage of the knee is subjected to excessive and uneven pressure due to the structural changes that accompany rapid growth. Chondromalacia may also occur in adults over age 40 as part of the wear-and-tear process that eventually leads to osteoarthritis of the knee joint. Other factors that may precipitate chondromalacia include trauma, overuse, or abnormal forces on the knee joint. It can develop in skiers, runners, cyclists, and soccer players, especially if someone is knock-kneed or flat-footed.

    The pain of chondromalacia occurs in the front or inside of the knee. The pain is generally worse with activities such as running, jumping, using stairs, or kneeling. The pain is also typically worse after prolonged sitting with the knees bent. This pain is called the “theater sign” of chondromalacia.
