Knee Information

Knee Anatomy and Function- Helpful Information from our Knee Specialist on Long Island

Understanding How the Knee Works

A joint is formed by two or more bones that are connected by thick bands of tissue called ligaments. The knee is the largest joint in the body and is made up of three main parts:

  • The lower end of the thigh bone, or femur.
  • The upper end of the shin bone, or tibia.
  • The kneecap, or patella.

The thigh bone (femur) turns on the upper end of the shin bone (tibia), and the kneecap (patella) slides in a groove on the end of the thigh bone. Ligaments, which are bands of tissue, connect the thigh bone and the shin bone to help keep the knee joint steady. The quadriceps, the long muscles on the front of the thigh, help strengthen the knee.

A smooth substance called articular cartilage covers the surface of the bones where they touch each other within the joint. This articular cartilage acts as a cushion between the bones. The rest of the surfaces of the knee joint are covered by a thin, smooth tissue liner called synovial membrane, which makes a small amount of fluid that acts as a lubricant so that the joint bones will not rub against each other.

What Causes Knee Pain?

One of the most common causes of knee pain and loss of mobility is the wearing away of the joint’s cartilage lining. When this happens, the bones rub against each other, causing significant pain and swelling. The most common cause is a condition known as osteoarthritis. Trauma or direct injury to the knee can also cause osteoarthritis. Without cartilage there is no shock absorption between the bones in the joint, which allows stress to build up in the bones and contributes to pain.

Your Treatment Options for Knee Pain

You may be able to get pain relief from treatments like steroidal and nonsteroidal anti-inflammatory drugs, physical therapy, bracing, and cortisone injections. But, if you’ve tried these methods and haven’t experienced adequate relief, you don’t have to live with severe knee pain and the limitations it puts on your activities.

Knee replacement surgery may provide the pain relief you long for and enable you to return to the things you enjoy doing. Remember, even if your doctor recommends knee replacement for you, it is still up to you to make the final decision. The ultimate goal is for you to be as comfortable as possible with your choice — and that always means making the best decision based on your own individual needs.

If you do choose surgery, you’ll be in good company: More than a quarter-million Americans have knee replacement surgery every year.1 First performed in 1968, the procedure typically relieves pain and restores joint function.

What is the Most Common Knee Injury?

Because of the stress our knees undergo from everyday activity, it’s no surprise that injuries to our knees are some of the most common that Orthopedists see each day. The bones, tendons, cartilage, and ligaments that make up the knee must deal with sitting, standing, walking, jumping, and whatever else we put them through. If you’ve recently been injured or suffer from knee pain daily and looking for a knee specialist on Long Island, the Orthopedists at Advanced Orthopedics & Joint Preservation can help.

Common Knee Injuries:

When trying to decipher which knee injury is the most common, it’s important to first have an understanding of knee injuries themselves, and how they are caused and treated. 

  • Dislocation – When the joint is completely disrupted, jarring the tibia and femur out of place. Dislocation is extremely painful and usually occurs following a hit or blow to the knee area. In some instances the knee corrects itself, if not a doctor must correct the bones manually.
  • Ligament Damage – Most commonly associated with sports, ligament damage occurs when the knee is moved in a way it’s not meant to. This inhibits the tendons from supporting the movement and puts them at risk of tearing or stretching. The four ligaments in the knee are abbreviated to PCL, MCL, ACL, and LCL and injuries to this area range from Grade I to Grade III. Lower-grade injuries include stretching and straining and don’t usually require surgery. Higher grades need surgery if the patient wishes to return to normal mobility without pain.
  • Meniscus Tear – This occurs when the knee is moved quickly due to a sudden change in direction while running, or because of jumping and twisting motions. These causes are why meniscus tears often are a result of sports, but it can tear due to wearing out over time. Treatment involves resting your knee and leg, elevating to reduce swelling, compression, and ice. If swelling continues or pain doesn’t diminish, surgery is recommended.
  • Fracture – Your knee cap, also known as the patella, can be seriously damaged after a fall or direct blow to the knee. The patella acts as a shield to protect the delicate parts that make up the joint, leaving it exposed to external damage. Depending on the severity of the fracture, surgery may not be required, demanding 6-8 weeks of no applied pressure. If the bones are out of place, surgery is needed to fix the knee cap. 

Given the complexity and grading scale of ligament related injuries, these are seen as the most common. Ligament sprains and stretches are painful but can go away without strenuous treatment such as surgery and physical therapy. While these are just some of the most common injuries Orthopedists see when dealing with knees, many other ailments are just as serious and painful. For many knee-related injuries surgery is not needed to properly heal, don’t hesitate to reach out to a knee specialist on Long Island at Advanced Orthopedics & Joint Preservation.

Am I Qualified For Knee Replacement?

Are you a patient who’s knee pain has become so severe that it prevents you from participating in daily activities? If so, it might be time to discuss your options with an orthopedic surgeon about knee replacement surgery. You may qualify for knee replacement surgery if nonsurgical treatments such as physical therapy, medications, or the use of a walking aid no longer provide pain relief. At Advanced Orthopedics & Joint Preservation, we can diagnose your condition to determine if a surgical procedure applies to your current impairment. If you are considering knee replacement surgery, call us today to schedule an appointment with a knee specialist on Long Island.

 What Should I Expect From My Orthopedist?

The knee is the most commonly removed joint in the body. More than 600,000 people worldwide have knee replacement surgery each year and around 90 percent see an overall improvement in their mobility. To determine whether you need knee replacement surgery, an orthopedic surgeon will do a thorough examination of your knee, perform an X-Ray, conduct tests, and evaluate your medical history or past injuries. You’ll also have a physical exam to test your strength and balance. Here are some reasons why you might consider visiting a knee specialist on Long Island today:

  • Extreme pain or loss of mobility: If you are experiencing a severe level of pain that stops you from performing daily tasks, you could qualify for knee replacement. It’s one thing to experience pain during intense physical activity, but it’s another thing if you feel knee discomfort from any sort of physical activity. Pain can also cause extreme joint stiffness and loss of mobility. 
  • Other treatments failed: Usually, an orthopedist will try to relieve your pain through nonsurgical treatments before recommending surgery. When nonsurgical treatments like physical therapy, medications, injections, a walking aid like a cane or a mobility aid fail to relieve pain, surgery might be your next option.
  • A bowing in your leg: Bowing in or out of your legs generally signal knee problems. Bowed legs eventually cause problems in the knees and hips because of the pressure that the curved legs put on these joints.

Treating Meniscal Tears

If you’ve just experienced a popping sensation in your knee, followed by pain and swelling, you may have suffered a torn meniscus. While this is a common knee injury, it cannot be taken lightly and should receive immediate treatment. Should you have any questions about this injury or how it is treated, our knee specialist on Long Island at Advanced Orthopedics and Joint Preservation can help assist you.

What is the Meniscus?

The piece of cartilage that provides a cushion between your femur and tibia is known as the meniscus. Each knee joint houses two menisci, which are known as semilunar cartilages due to their crescent-like shape. The main function of the meniscus is to reduce the wear and tear placed on the femur and tibia from the movement of the joint.   Unfortunately, tears to this vital piece of cartilage are fairly common, often resulting in an athletic injury.   


Initially, when a meniscus tear occurs you may hear or feel a pop around your knee joint. After this, you may also experience:

  • Difficulty moving your knee.
  • Pain.
  • Swelling.
  • The feeling that your knee is unable to support you.

Reaching out to Advanced Orthopedics and Joint Preservation immediately after experiencing these symptoms can increase your recovery time.

Common Causes of Tears

Although meniscus tears are commonly associated with athletic based injuries, you don’t need to be a sports superstar to experience one. Something as simple as getting up too quickly from a squatting position can even lead to a tear. Any activity that causes you to vigorously twist and rotate your knee can result in a torn meniscus. Due to the nature of the game, some sports that are the most common culprits for this type of injury are some of the following:

  • Basketball.
  • Football.
  • Soccer.
  • Tennis.

No matter the cause, our knee specialist on Long Island has the necessary experience to guarantee proper injury treatment. 

Treatment and Rehab

In some cases, treating a torn meniscus can be done on your own by following the RICE method. This method includes resting, icing, compressing, and elevating the affected knee to reduce swelling and pain. If your knee is not receptive enough to this treatment, our knee specialist on Long Island may determine that surgery is needed. Some types of surgery that can be done to repair the knee are:

  • Arthroscopic repair – Small dart-like devices will be placed along with the tear as a means to stitch it up. 
  • Arthroscopic partial meniscectomy – A small piece of the torn meniscus is removed allowing the knee to function properly. 
  • Arthroscopic total meniscectomy – The entirety of the meniscus is removed.

It may be 4-6 weeks before you are fully healed from this type of injury. Contact Advanced Orthopedics and Joint Preservation today to learn more and discuss what treatment options are best for you.
