Referred Pain To The Knee

Why Is My Knee In Pain When Bending It?

There are several conditions in which a person can develop knee pain, despite any pathology being present in the knee whatsoever. The lower back and hip joint are both known to refer pain as far as the knee and even beyond when problems arise. Conditions of the spine where the discs or joints become compromised, potentially leading to a pinched nerve, can result in pain down the leg. If the L3-4 and L4-5 spinal levels are affected, you may experience pain that refers to the knee. If you develop an onset of pain that seems to travel to the knee and is accompanied by a new onset or change in your back pain, it may be suitable for you to be seen by a health professional who can help determine whether your pain is knee related or coming from your lower back.

There are several muscles around the hip joint that are known to refer pain down to the knee. When a muscle becomes tight and irritated, pain can often be felt beyond the borders of that muscle, and in the case of some of the muscles on the front or side of the hip, we will often feel the pain spread down as far as the knee. Many cases of knee pain are blamed on the iliotibial band , however, often, the problem is higher up in the hip. There should always be an assessment of the hip whenever there is knee pain.

Chronic Pain Behind The Knee

Pain at the back of the knee may occur gradually. You are unlikely to be able to pinpoint the exact time your injury occurred. These injuries often start out as a niggle which you may attempt to ignore. Eventually, they become progressively worse.

An acute injury may become chronic if it is not treated properly, or fails to heal.

Chronic knee injuries can be more difficult to treat so do not ignore the early signs!

If You Have Pain Behind Your Knee After Sitting:

It is likely you are experiencing a symptom of Chondromalacia Patellae. This is the most common cause of chronic knee pain. Chondromalacia Patellae is caused by your patella being pulled to the outer side of your femur, rather than in a straight line. This will cause discomfort when you stand up from sitting in a chair for a long period of time. In order to prevent this at work, taking microbreaks will help to keep your body loose. You may also feel discomfort after physical activity or a tightness or fullness in the knee area.

Understanding The Anatomy Of The Knee

To understand why the knee hurts when bent, we first must understand its anatomy and how it works. The bones of the lower and upper legs are connected by the knee joint. This joint consists of muscles, tendons, ligaments, cartilage, and bones that work together to allow us to move, give us flexibility, and support our body weight. Proper functioning of this joint also enables us to stand, walk, squat, jump, and turn. Lets examine the knee joint in detail.

What Causes Swelling Behind The Knee

Kneecap Pain When Bending Knee

There are a number of different causes of swelling behind the knee. In most cases, back of knee swelling is caused by a build-up of fluid or an abnormal growth in the popliteal space the soft area at the back of the knee.

Here we look at five common causes of swelling behind the knee, the causes and symptoms of each, how to tell whether its something serious and the best ways to treat causes of swelling behind the knee.

Brief Anatomy Of The Knee

The knee is a vulnerable joint that bears a great deal of stress from everyday activities, such as lifting and kneeling, and from high-impact activities, such as jogging and aerobics.

The knee is formed by the following parts:

  • Tibia. This is the shin bone or larger bone of the lower leg.

  • Femur. This is the thighbone or upper leg bone.

  • Patella. This is the kneecap.

Each bone end is covered with a layer of cartilage that absorbs shock and protects the knee. Basically, the knee is 2 long leg bones held together by muscles, ligaments, and tendons.

There are 2 groups of muscles involved in the knee, including the quadriceps muscles , which straighten the legs, and the hamstring muscles , which bend the leg at the knee.

Tendons are tough cords of tissue that connect muscles to bones. Ligaments are elastic bands of tissue that connect bone to bone. Some ligaments on the knee provide stability and protection of the joints, while other ligaments limit forward and backward movement of the tibia .

Types Of Knee Pain When Bending

Pain in the Knee, with Locking in the Joint

Inside the knee joint, there are two C shaped pieces of cartilage called menisci, which keep the surfaces of the upper leg bone and lower leg bones from grinding against each other. Injuries to this cartilage usually result from a trauma, like landing a jump or twisting your knee. You may also notice problems with range of motion, walking, or even a locking sensation in the joint. Resting the knee and managing inflammation will help heal minor tears, while physical therapy can help strengthen and stabilize it.

Pain Behind the Kneecap

Patella-Femoral Syndrome is a term that describes joint pain between the kneecap and upper leg bone. Under the kneecap is a smooth cartilage lining that creates a gliding surface between the bones, and if it softens or wears away it can result in pain and inflammation. According to Neuromuscular Specialist and co-founder of the Performance Institute in New York City, major contributing factors to this knee pain are poor alignment when landing, as well as imbalanced quadricep muscles, which can pull the kneecap side to side. Strengthening the quads and stretches to lengthen hamstrings and calfs will help reduce the risk of injury.

Tendinopathy And Muscle Complex Injuries

Tendon injuries are associated with repetitive mechanical stresses that cause degenerative lesions. Hamstrings, gastrocnemius, and popliteus tendon typically cause posterior knee pain.

The hamstrings are frequently injured in sports that require sprinting. Semimembranosus tendinopathy usually presents as an aching pain localized to the posteromedial knee with tenderness on palpation inferior to the joint. Some of the possible risk factors for hamstring injury include body mechanics, flexibility, balance, hamstring strength, improper warm-up, fatigue, specific activities, running techniques, and psychosocial factors.

The gastrocnemius muscles superficial location and action across the knee and ankle make it susceptible to injury. Pain in the gastrocnemius occurs during knee flexion with resistance and during calf raises.

The popliteus muscle can also be a significant source of posterior knee pain. Both the muscular and tendinous aspects of the popliteus can be injured. Injuries to the popliteus may promote injuries to other structures in the postero-lateral complex and to ligaments of the knee. The mechanism of injury is thought to occur from direct stretch or when overused to maintain posterolateral stability. Guha et al. suggested that a stable knee with posterolateral pain and hemarthrosis on exam indicates a rupture of the popliteus tendon.

Issues That Can Cause Pain Behind The Knee While Youre Bending It

What is Causing the Pain Behind Your Knee, How to Tell

The knee is one of the most complex joints in the human musculoskeletal system, and physical therapists are trained to treat this system. This knowledge allows your therapist to pinpoint the cause of your knee pain. Some common issues that typically cause posterior knee pain include:

  • Knee bursitis Bursae are small sacs of fluid that help reduce friction between bones and soft tissue. Your knee contains several of these structures. The semimembranosus bursa is one thats located at the back of the knee. When it becomes inflamed, it can trigger posterior knee pain.
  • Hamstring tendinitis There are tendons that connect the hamstring muscles to your knee. Hamstring tendinitis occurs when these tendons become inflamed. This condition often leads to posterior knee pain, joint weakness and swelling behind the knee.
  • Ligament injuries Both the anterior cruciate ligament and the posterior cruciate ligament are located in the middle of the knee. Injuries to these ligaments can cause pain to radiate into the back of your knee.

    Hamstring Injury And Pain At The Back Of The Knee

    An injury to your hamstring is a very common reason for sharp pains at the back of your knee.

    Your hamstring starts at the bottom of your pelvic bone and crosses the back of the knee and ends at the lower leg. Doctors from the American Academy of Orthopedic Surgeons say that your hamstring helps you bend your knee.

    Hamstring injuries can result in pulling the hamstring muscle or completely tearing it. This can result in pain at the back of your leg below your knee. You may also notice bruising of your leg and may find it difficult to walk for a few weeks.3

    Dr. Tyler Wheeler on WebMD says that you can prevent hamstring injuries by warming up before exercising. You should also strengthen your glutes which make up your buttocks to prevent extra strain on your hamstring muscles.

    At the end of the article, you can find out how to treat a pulled or torn hamstring and help ease the pain behind your knee.

    Burning Pain In Knee Cap

    When you feel pain in your knee cap, you imagine the worst. You begin to believe you’ve injured your knee. Maybe you even wonder if you have a torn meniscus.

    Burning pain under or around your knee cap is a common overuse injury. The official diagnosis for this syndrome is chondromalacia or patellofemoral pain syndrome, also known as PFS. The injury is also commonly known as runner’s knee.

    When you run, you put stress on your knee cap and the tendons in it. If you’re not used to running long miles and attempt a long run, you will feel this pain. You will also feel it if you begin to increase your mileage too quickly.

    Your tendons in your knee cap are firing up and becoming inflamed. You have tendonitis in your knee or runner’s knee.

    Stopping activity will help this heal more quickly as will ice and appropriate NSAID or anti-inflammatory medications.

    How Did You Hurt Your Knee

    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.

    Common knee pain problems in your teenager can be generally divided into three types:

    • Anterior knee pain, also called patellofemoral pain.
    • Injures to ligaments and tendons of the knee or to the kneecap itself.
    • Medical conditions that affect the knee.

    Anterior knee pain happens when your teens kneecap is pulled out of its groove from increased pressure. Increased pressure on the knee joint is caused by:

    • Abnormal hip rotation due to imbalances in muscle strength and flexibility around the hips.
    • Improper training methods or equipment.
    • Poor flexibility of the thigh muscles, which support the knee joint. Thigh muscle weakness or tightness.
    • Overuse of the knee from repetitive bending of the knee during running, jumping, and other activities.
    • Problems with alignment, for example, the kneecap not being properly aligned within the knee or having flat feet, which changes the normal gait.

    Knee pain resulting from sprains, strains and tears to ligaments and tendons or injuries to other soft tissues. These conditions include:
