Congrats on your appointment to serve at the

Orthopedic conditions affect people of all ages, from new borns to elderly individuals. Some conditions may be congenital while some may be developed after birth.
Our expert team of physicians, surgeons and nurses specialize in providing the utmost care and best possible treatment for spine disorders in the pediatric population.
Sports medicine involves treating sports injuries which occur when playing indoor or outdoor sports or while exercising.
The hip joint is one of the body’s largest weight-bearing joints and is the point where the thigh bone (femur) and the pelvis (acetabulum) join.
Limb lengthening is a reconstructive procedure where the deformed bone is straightened or missing bone is replaced.

ACL Tears

The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee that is located in the middle of the knee and runs from the femur (thigh bone) to the tibia (shin bone). It prevents the tibia from sliding out in front of the femur. Together with posterior cruciate ligament (PCL) it provides rotational stability to the knee.

An ACL injury is a sports related injury that occur when the knee is forcefully twisted or hyperextended. ACL tears in dancers often occur in a performance when landing from a leap or twisting in an unplanned way. An ACL tear usually occurs with an abrupt directional change with the foot fixed on the ground or when the deceleration force crosses the knee. Changing direction rapidly, stopping suddenly, slowing down while running, landing from a jump incorrectly, and direct contact or collision.

When you injure your ACL, you might hear a “popping” sound and you may feel as though the knee has given out. Within the first two hours after injury, your knee will swell and you may have a buckling sensation in the knee during twisting movements.

Diagnosis of an ACL tear is made by knowing your symptoms, medical history, performing a physical examination of the knee, and performing other diagnostic tests such as X-rays, MRI scans, stress tests of the ligament, and arthroscopy.

Treatment options include both non-surgical and surgical methods. If the overall stability of the knee is intact, your doctor may recommend nonsurgical methods. Non-surgical treatment consists of rest, ice, compression, and elevation (RICE protocol); all assist in controlling pain and swelling. Physical therapy may be recommended to improve knee motion and strength. A knee brace may be needed to help immobilize your knee.

Young athletes involved in pivoting sports will most likely require surgery to safely return to sports. The usual surgery for an ACL tear is an ACL reconstruction which tightens your knee and restores its stability. Surgery to reconstruct an ACL is done with an arthroscope using small incisions. Your doctor will replace the torn ligament with a tissue graft that can be obtained from your knee (patellar tendon) or hamstring muscle. Following ACL reconstruction, a rehabilitation program is started to help you to resume a wider range of activities.
