The knee joint contains the femur (thigh bone), tibia (shin bone) and the patella (knee cap). These bones are covered by a protective substance called articular cartilage which enables easy, smooth movements.

The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope-like structure located in the center of the knee running from the femur to the tibia. When this ligament tears, it doesn’t heal and often leads to the feeling of instability in the knee.
ACL reconstruction is a commonly performed surgical procedure. With recent advances in arthroscopic surgery, it can be performed with a minimal incision and low risk of complications.
Ligament reconstruction is surgery to reconstruct a torn ligament using a graft or artificial prosthesis. Ligaments are tough, non-stretchable fibers that hold your bones together. Ligament reconstruction is performed to improve joint function and stability and may be indicated for shoulder, elbow and knee injuries.

Arthroscopy is a surgical procedure in which an small camera is inserted into a joint. Arthroscopy is a term that comes from two Greek words, arthro-, meaning joint, and -skopein, meaning to examine.
The benefits of arthroscopy include smaller incisions, faster healing, more rapid recovery, and less scarring. Arthroscopic surgical procedures are often performed on an outpatient basis and the patient is able to return home on the same day.

The knee joint is one of the largest and the most complex joint in the body. The joint is made up of the femur (thigh bone), the tibia (shin bone), and patella (kneecap). Between the femur and the tibia lie two wedge-shaped pads of cartilaginous tissue called menisci, which serve to reduce friction in the joint as well as act as shock absorbers. The two menisci present in the knee are the lateral meniscus, on the outside, and the medial meniscus, on the inside of the knee.

The tough yet elastic tissue that covers the ends of bones in the knee is called articular cartilage. Working in tandem with meniscal cartilage, articular cartilage acts as a shock absorber for the knee, allowing the joint to withstand the day-to-day pressures of walking, running, sitting and standing.

What is Osteoarthritis (OA)?
Gradual breakdown of articular cartilage and bones within a joint. Osteoarthritis is typically caused by wear and tear and worsens over time. It most often occurs in individuals over the age of 50 but can be present in younger patients. Individuals with osteoarthritis may experience pain, swelling, stiffness and/or limited range of motion.
