What Are the Most Serious Ligament Injuries

Your ligaments are flexible, strong bands of tissue that connect your bones to other bones in your joints. They make movement possible, allowing you to bend your knee or flex your foot. They also stabilize your joints (and you) by keeping your bones in their proper orientation. Although sturdy, ligaments can tear when strained or stretched beyond their capacities. 

Unfortunately, ligament injuries are relatively common, particularly in athletes and others who lead very active lifestyles. There are three levels of ligament injury. Grade one is a slight ligament tear or excessive stretch, as many individuals experience when spraining an ankle. Grade two is a moderate ligament tear, and grade three is a total ligament tear, where the ligament has detached from the bone or torn completely.

Complete ligament tears are also called ruptures, requiring surgical intervention to repair. Since your ligaments support your bones and help with flexibility, a total tear will severely limit your mobility.

Who Is at Risk for Ligament Injuries?

While athletes often experience ligament injuries, anyone can suffer from a ligament injury. Tears can happen when a ligament is fully stretched and exposed to trauma. An example would be turning your ankle while running, landing awkwardly from a jump, and slipping or falling during your daily routine. Elderly individuals are at increased risk of injury as their ligaments may weaken due to age, and are more likely to experience falls.

What Joint Is Most Likely to Experience Ligament Injuries?

Ligament injuries frequently occur in the knees. This is because your knees are critical for all body movement, and they also experience a lot of pressure due to having to support most of your body weight. Four major ligaments move and support your knee: the medial collateral ligament (MCL), posterior cruciate ligament (PCL), anterior cruciate ligament (ACL), and lateral collateral ligament (LCL).

Many healthcare practitioners consider (ACL) the worst ligament to injure in terms of affecting mobility and stability. Unfortunately, it is also one of the most common ligament injuries orthopedic doctors see.

The ACL stabilizes the knee by controlling the movement of the lower leg, preventing hyperextension of the joint. After an ACL tear, the knee will usually become extremely unstable and swollen, and the patient will struggle to bear weight on it. However, not all ACL injuries cause intense pain. Sometimes, rather than feel pain, an individual will first realize they have injured the ligament when they hear a popping sound.

Diagnosing and Treating an ACL Tear

To diagnose an ACL tear, your doctor will physically examine your knee and ask questions about how you were injured and the symptoms you are experiencing. In addition, your doctor will likely have an MRI done on your knee to get a complete image to assess the extent of the damage.

Treatments for an ACL tear will depend on the severity of the tear. Common treatments for ACL injuries include anti-inflammatory medications, muscle-strengthening exercises, icing, protective braces, and, in the case of a complete or near-complete tear, surgery.
Injuring any of the ligaments in your knee will put a serious damper on your day-to-day activities. To get back on your feet, seek medical care as soon as possible; contact Tchejeyan Orthopedics Sports Medicine today.

Arthritis is not technically a disease, but a condition defined by inflammation of the joints. It can affect one joint or many joints, and it can cause pain, stiffness, swelling, and weakness in the joints. It afflicts more than 50 million adults and over 300,000 children in the United States. Medical specialists break down arthritis into more than 100 different types, some of which go by another name. The most common type is osteoarthritis, but rheumatoid arthritis, gout, fibromyalgia and lupus are all classified as arthritic conditions. When you take it as a whole, arthritis, then, can strike at any age. However, the most common type, osteoarthritis, is the one that most people think of when they think of arthritis, and the type of arthritis people mean when talking about the knees. Osteoarthritis usually develops after the age of 50, but it can occur at any age. Since it is caused, essentially, by “wear and tear” on the knee joint, people who do a lot of weight-bearing activities can develop it early on in life. For example, a warehouse worker who has to carry heavy boxes around on a concrete floor every day and puts a lot of repetitive stress on his knees may develop arthritis while in his 30’s. The fact is, most people have some level of arthritis once they reach their 60’s, simply because the cartilage in the knee wears down after so many years of use and of bearing most of the body’s weight. Some people have a genetic predisposition to get arthritis, and those who are very physically active and those who already have bone anomalies are also more at risk. More men than women get arthritis before the age of 50, but after 50, more women than men will get arthritis. This is often because women gain wait after menopause, and this extra weight can put extra stress on the joints after half a lifetime of wear and tear. When to See a Specialist While pain and stiffness are the most common symptoms of arthritis, there are several other indicators. “Crepitus” is the word that is given to the creaking, grinding, snapping, or clicking noise that happens when patients move their joints, and it is a common symptom of arthritis. In addition, a person may have difficulty walking, the knees can buckle, skin can swell or feel warm or look red. If you have any of these symptoms and they do not abate after a few weeks of rest and taking over-the-counter anti-inflammatory or pain reliever medications, you should see an orthopedic specialist. Initially, your doctor will examine your knees to see if the symptoms you are experiencing are consistent with arthritis, or may be indicative of other knee problems. Your doctor will perform diagnostic tests, and may order images of your knee. If you are diagnosed with arthritis, the next step will be to determine what the appropriate treatment should be. How to Treat Arthritis in the Knees Nowadays, most joint diseases can be treated without any surgery or with minimally invasive surgical procedures. If your arthritis is not very advanced, your doctor might recommend that you take some basic steps that can relieve your condition, such as losing weight, selecting lower-impact exercises like walking, wearing special inserts in your shoes, wearing a knee brace, and getting some physical therapy. In many cases, these simple steps can do a great deal to relieve pain and weakness in the knees, and will provide more broad health benefits, as well. If the arthritis has progressed to the point that there is significant loss of bone and loss of cartilage, surgery is likely to be necessary. When possible, Dr. Tchejeyan at Tchejeyan Orthopaedics and Sports Medicine utilizes arthroscopy, a minimally invasive surgical method which usually does not involve the use of general anesthesia and is performed as an outpatient procedure. Take Care of Your Knees and Take Care of Your Health Even if you are young, you can get arthritis, so do not ignore chronic knee pain, thinking that it will “just go away” or that you are too young to have this condition. Arthritis in the knees can become so debilitating that it can prevent you from being able to carry out even normal, everyday activities. What is more, when you cut back on activities like walking, not only can the arthritis get worse, but your overall health will suffer and your enjoyment of life can be greatly reduced. If you have knee pain and suspect it may be arthritis, you need to get it diagnosed and treated so that you can get back on track with your life, regain your vigor, and improve your health.
