It indicates that something is getting stuck in the joint. It can be a loose body or a flap of torn cartilage. It may also indicate instability due to sprain or tear.

Damage to the pain that radiates from the inner side of the leg. Knee pain can occur immediately after an accident, usually due to a twisted knee, but it can also persist for some time while the knee recovers.

Osteoarthritis sufferers sometimes experience sharp knee painwhen sitting for long periods, such as 20-30 minutes. You may have arthritis if your knee pain subsides after a few minutes of action.

How Does The Knee Bend

The knee is a hinge joint, which means its main movement is bending and straightening . As the knee moves, a number of things are happening:

Muscles: They work in pairs with one relaxing and the other contracting to allow the movement e.g. to bend your knee you hamstrings contract and you quads relax

Bones: The femur and tibia have to roll, glide and spin to move smoothly. The patella shifts, tilts and rotates as it glides up and down through a groove on the thigh bone the position and movement of the patella is controlled by the surrounding muscle.

Cartilage: The special shock-absorbing cartilage that lines the knee moves and changes shape slightly to prevent it from getting trapped

Ligaments: These help control the movement and maintain stability by preventing excessive movement of the bones. There are two pairs of ligaments, the cruciate ligaments in the middle of the joint, and the collateral ligaments on either side

These structures all need to work together properly to allow for smooth, pain-free knee bending and straightening. Problems in any of these areas can lead to knee pain when bending. For example, if there is muscle weakness or ligament instability, the bones may move slightly out of position causing them to catch or grind on other structures in the knee.

Anterior Knee Pain Causes In Young Athletes:

Before you read this, it is worth repeating the majority of you will not have the issues that I outline below. The majority of you will have pain due to a gait abnormality or muscle imbalance. We all feel the need to have a specific label for why our knee hurts. Anterior knee pain due to muscle imbalance just doesnt cut if for some of you you want something more specific. I understand that.

The point I am trying to make is, if you assign the cause of your pain to a specific structural finding or something that your MRI report mentioned, then you may have difficulty getting past that and buying into the PT or exercise strategies that have been shown to work.

  • Chondromalacia: Chondromalacia is likely a very early sign of arthritis. It involves the softening of the cartilage under your patella . As the cartilage softens, it is thought that it irritates other tissue in the knee with certain activities. Im not convinced that this is a common cause of anterior knee pain. Chondromalacia is very common, even in people with no pain.

We find chondromalacia in so many people at the time of surgery for other things, such as an ACL tear. And those people rarely have pain in the front of their knee. So it is not entirely clear why some people might have pain due to chondromalacia, and others do not. Surgery is rarely needed.

Osteoarthritis : Arthritis of the patella causes pain because the cartilage under the kneecap is thinning. Arthritis, which only involves the patella in your knee, is more common in women. Physical therapy can be very effective in the early stages of osteoarthritis of the patella. Injections and over the counter medications may have a role in some patients. In some situations, when the arthritis is severe, a patient will need to consider a tibial tubercle osteotomy, replacement of the patella, or a total knee replacement if the arthritis is elsewhere within the knee.

How To Manage The Pain

Causes of Sharp Pain in the Kneecap when Climbing Stairs » Scary Symptoms

When you have knee pain when bending, there are some things you can do to help ease the pain. Depending on the injury and the amount of pain, you may even be able to eliminate it completely.

  • Allow your knees to rest for a few days after intense activities.
  • Put ice on your knee for 15-20 minute intervals every 3-4 hours for 2-3 days. This will ease the pain and help reduce the swelling.
  • Keep swelling down by adding support with a brace or bandage.
  • When you are sitting or lying down, place a pillow under your heel and knee to help reduce the pressure.
  • Use anti-inflammatory medications such as ibuprofen to help reduce pain and swelling.
  • Complete daily stretching and strengthening exercises to help keep the muscles, tendons, and ligaments around the joint strong.

Ligament Sprain Or Tear

Knee ligaments

Ligaments are soft tissue structures that help to stabilize the joint. A complete tear of any of the ligaments can cause stability issues along with pain and significant swelling. Partial tears of the ligament can cause sharp pain with movement along with some swelling.

Listed above are only some of the problems that may arise at the knee joint. It is important to be evaluated properly if you are having sharp knee pain. Many of these conditions can be managed conservatively and respond well to physical therapy. Stretching, strengthening and manual therapy can aid in recovery.

JOI is an expert with sharp knee pain. If you suspect that you may have one of these injuries, you should consider seeing a specialist. Be smart about your health. Get assessed, dont guess!

Is Anything Strange Happening

Or really, Is anything strange happening beyond your knee pain?

For example, can you still flex your knee all the way? Most people get frightened when their knee locks and cant straighten anymore. Often the culprit is called Bakers cyst, a fluid-filled sac behind the knee caused by inflammation.

A also triggers concern for many people. Nobody wants to hear a click with every step. Sometimes, its harmless, but if that clicking comes with pain, you might have a mechanical problem such as a torn meniscus, Dr. Burg says.

These are just a few examples among many. The knee is a complicated andcritical part of your everyday life. So when you have pain that comes withserious symptoms or lasts for more than a week or two, seek the right diagnosisby getting a physical exam and any necessary imaging that comes with it.

Sharp Pain And A Popping Sound

If you experience a sharp pain and popping sound when bending, you may have:

  • A ligament tear. The knee has four primary ligaments that stabilize and support the joint. A direct blow or sudden twisting motion can overstretch or tear any of the ligaments in the knee. Ligament injuries typically cause sudden, sharp pain, swelling, and a popping sound at the time of injury.
  • A meniscus tear. The knee has two C-shaped discs of cartilage on either side of the joint, called the menisci. A forceful twisting motion can cause either meniscus to tear. Meniscus tears typically cause a popping sound at the time of injury. Pain can be immediate or it can develop over the next several days.

Sharp Knee Pain When Standing Still

How to Fix Patellar Tendonitis (No More KNEE PAIN!)

If your knee pain gets worse after prolonged stillness but eases with movement, it is likely from arthritis.

That stiff feeling occurs because the joint-hydrating fluid surrounding the knee has grown still because of a lack of movement. This may occur during sleeping, sitting, or standing for extended periods of time.

TIPS TO AVOID PAIN: isometric exercises are extremely low-impact and great for rapidly strengthening muscles, as well as supporting tendon and ligament health.

Try incorporating one or two of these isometric exercises when youve noticed youve had a prolonged period of no movement. They are great when performed before getting out of bed in the morning, or before you get up from sitting.

Knee Function And Anatomy

The knee is a complex system of bones, cartilage, ligaments, tendons, and muscles responsible for weight-bearing and movement. See this image for a visual representation of these many components and how they connect. Any situation or condition that causes stress, inflammation or injury to any of these components can result in sharp knee pain.

  • Bones: The bones of the knee include the femur , patella , and tibia . The knee joint works to keep these bones securely in place.
  • Cartilage: The two types of cartilage in the knee are the minuscular cartilage and the articular cartilage. The cartilage act as cushions around the bones of the knee that reduce friction during movement, and help the bones move smoothly against each other. There is a medial meniscus on the inner side of the knee and a lateral meniscus on the outer side of the knee.
  • Ligaments: The knee has four ligaments that connect bones to other bones and promote stability: medial collateral, lateral collateral, posterior cruciate, and anterior cruciate ligaments. These ligaments prevent the side-to-side movement of the femur as well as excessive backward and forward movement of the femur and tibia.
  • Tendons: The tendons are similar to the ligaments and connect bone to muscle. The patellar tendon is the largest and attaches to the quadriceps.
  • Joint capsule and bursa: The joint capsule and bursa are fluid-filled membranes that lubricate the joint and reduce friction.

Furniture And Knee Pain

The ergonomic design of the chair that youre sitting in can have an impact on knee pain.

For example, if you sit for long periods of time at the office, your chair should be properly designed and positioned correctly with the other furniture you are using, such as your desk.

If your workspace is not positioned at the correct distance and height, you could be holding yourself in an awkward position that, over time, can result in knee pain.

Knee pain at a workstation is often intensified by the chair being too low or positioned so you keep your knees bent for too long.

What Is Pain Behind The Knee

What Causes Knee Pain When Squatting or Bending?

Since the knee is the largest and most complex joint in the body, it makes sense that it might hurt sometimes. Although knee pain is a common complaint, it is less common behind the knee.

Pain in the back of the knee is called posterior knee pain, and it can have a variety of causes. Occasionally, posterior knee pain is “referred” from the front of the knee or the spine.

Workspace Ergonomics: Best Practices

According to Mayo Clinic, if you work at a desk or counter, you can take these steps to ease knee and other joint pain:

  • Select an ergonomic chair that properly supports your spinal curves.
  • Set the height of your chair so when your feet are resting flat on the floor, your thighs are parallel to the floor.
  • Consider a footrest if you cant adjust chair height properly, or if the height of your desk requires you to raise your chair beyond where you can rest your feet flat on the floor.
  • Adjust the chairs armrests so your arms can comfortably rest on them with your shoulders relaxed.
  • Your desk should allow clearance for your knees, thighs, and feet.
  • If you work at a computer, put the monitor directly in front of you with the top of the screen at eye level . It should be about an arms length away when youre sitting up straight in your chair.
  • Your keyboard should be directly in front of your monitor.

If you have knee pain while sitting, you might also consider a standing desk.

If you have knee pain when sitting, a number of reasons could cause it, including:

  • sitting with your knees bent for too long
  • poor furniture ergonomics

Where Is Your Pain

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

The hunt for the cause of knee pain is like the search for a home:Location matters.

For example, pain below your kneecap might be a sign of patellar tendinitis, or inflammation in the tendon that connects the kneecap to the shinbone, says rheumatologist Scott Burg, DO. Pain above the kneecap often means quadriceps tendinitis.

Pain on the inside or outside of your knee could be a sign of a torn ligament , Dr. Burg says. But it also could indicate a torn or degenerative meniscus, which is the cartilage that lines and cushions your knee joint.

Those are just a couple of causes, not including various types of arthritis. Location is important, but we also ask other questions, Dr. Burg explains.

Sharp Knee Pain When Taking The Stairs

There are two directions/causes of this type of sharp knee pain.

When traveling up the stairs, this indicates a problem within the knees tibiofemoral joint. When traveling downstairs, the problem most likely stems from the knee cap.

Both of these are considered mechanical problems within the knee. Either way, the solution actually remains the same!

TIPS TO AVOID PAIN: if your knees arent aligned with the rest of your body, it can aggravate your knees causing the sharp pain with stairs. Start with these 3 simple stretches to realign your knees and relieve discomfort.

Can You Bend Your Knee With A Torn Meniscus

It may be difficult to bend or straighten your knee fully if you have a torn meniscus. This is because bending or straightening the knee places pressure on the menisci located in between the thigh and the shin bones.

With a torn meniscus, it is best to rest and refrain from placing weight on the affected knee to give it time to heal and avoid the injury from worsening.

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 .
