Knee Injury

knee injury

The knee is a very large and complex joint, composed of several bones, ligaments, and muscles. Because of its complexity and frequency of use, this joint is particularly prone to injury. Whatever your knee injury, Dr. Rovner provides a variety of treatments at his New Jersey area practice. He believes in a conservative approach to treatment, and will try non-invasive therapies before recommending surgery. When surgery is necessary, he can use advanced, arthroscopic techniques that will get you back to enjoying the activities you love in no time. To learn more, schedule your consultation with Dr. Rovner today.

The Anatomy of Your Knee

Your knee links two major leg bones: your femur (thigh bone) and tibia (shin bone). Between the bones are two C-shaped pieces of cartilage, called the medial and lateral menisci, that help to absorb shock and balance your weight across your knee. Articular cartilage covering the ends of the both of the bones provide additional absorption support for the joint. In front of the joint, the bony patella (knee cap) offers protection. On either side of the knee, the medial and lateral collateral ligaments (MCLs and LCLs) help to stabilize your knee and prevent the joint from moving too far to the side. One of the most important ligaments, the anterior cruciate ligament (ACL) is located in the center of the joint and prevents the tibia from rotating too far forward. Conversely, the posterior cruciate ligament (PCL) is located just behind the ACL and prevents the tibia from moving too far backward.

Common Knee Injuries

Dr. Rovner treats a wide range of knee injuries, including:

  • MCL injury: The MCL is the most commonly injured ligament in the knee, especially in sports injuries. An MCL sprain occurs when there is damage or a tear to the ligament, and can be caused by an outside force hitting the knee or when the foot is stopped and the body continues in motion. The symptoms of an MCL sprain include a popping or tearing noise at the time of the injury, swelling, bruising, stiffness, and difficulty walking.
  • ACL injury: An ACL injury is similar to an MCL injury in its causes and symptoms. An ACL injury can involve anything from mild damage to a complete tear. It usually occurs from improper movement, such as stopping too suddenly, although an outside blow can also damage the ACL. Symptoms include pain and swelling within 24 hours of the injury, difficulty walking, tenderness to the touch, and a compromised range of motion.
  • Meniscal injuries: Meniscal tears are one of the most common types of knee injuries. Although athletes most often suffer meniscal tears, patients of all activity levels can sustain this injury, especially as they get older. The symptoms of a torn meniscus include pain, swelling, stiffness, a feeling that the knee is about to give out, and a limited range of motion.
  • Chondromalacia and other cartilage injuries: Chondromalacia, also known as “runner’s knee” involves the deterioration of the cushioning cartilage between the femur and tibia. The condition can affect young athletes who put significant daily strain on their knees, but it can also affect older patients, especially those with arthritis. Symptoms of chondromalacia include a dull pain in the knee, especially when walking, going up the stairs, or after sitting for an extended period. Patients may also notice a popping or clicking noise in the knee.

Dr. Rovner can treat many of the above injuries with minimally-invasive surgery. With his safe and innovative techniques, patients can enjoy faster healing times, shorter hospital stays, and minimal surgical entry points and scaring.
