Knee

Knee Anatomy

The knee is a complex joint made up of different structures - bones, tendons, ligaments, and muscles. They all work together to maintain the knee’s normal function and provide stability to the knee during movement.

Having a well-functioning healthy knee is essential for our mobility and ability to participate in various activities. Understanding the anatomy of the knee enhances your ability to discuss and choose the right treatment procedure for knee problems with your doctor.

Bones of the Knee

The knee is a hinge joint made up of two bones, the thighbone (femur) and shinbone (tibia). There are two round knobs at the end of the femur called femoral condyles that articulate with the flat surface of the tibia called the tibial plateau. The tibial plateau on the inside of the leg is called the medial tibial plateau and on the outside of the leg, the lateral tibial plateau.

Knee Conditions

  • KneeACL Tears

    An ACL injury is a sports-related injury that occurs when the knee is forcefully twisted or hyperextended. An ACL tear usually occurs with an abrupt directional change when the foot is fixed on the ground or when the deceleration force crosses the knee.

  • KneeKnee Arthritis

    The joint surface is covered by a smooth articular surface that allows pain-free movement in the joint. Arthritis is a general term covering numerous conditions where the joint surface or cartilage wears out.

  • KneeKnee Pain

    Knee pain is a common condition affecting individuals of various age groups. It not only affects movement but also impacts your quality of life. An injury or disease of the knee joint or any structure surrounding the knee can result in knee pain.

  • KneePatellar Instability

    Any damage to the supporting ligaments may cause the patella to slip out of the groove either partially (subluxation) or completely (dislocation).

  • KneeQuadriceps Tendon Rupture

    The quadriceps can rupture after a fall, direct blow to the leg and when you land on your leg awkwardly from a jump. Quadriceps tendon rupture most commonly occurs in middle-aged people who participate in sports that involve jumping and running.

  • KneePatellar Tendon Rupture

    The patellar tendon works together with the quadriceps muscle and the quadriceps tendon to allow your knee to straighten out. Patella tendon rupture is the rupture of the tendon that connects the patella (kneecap) to the top portion of the tibia (shinbone).

  • KneeArticular Cartilage Injury

    Articular or hyaline cartilage is the tissue lining the surface of the two bones in the knee joint. Cartilage helps the bones move smoothly against each other and can withstand the weight of the body during activities such as running and jumping.

  • KneeKnee Fracture

    A fracture is a condition in which there is a break in the continuity of the bone. In younger individuals, these fractures are caused by high energy injuries, as from a motor vehicle accident.

  • KneeMultiligament Knee Injuries

    Injury to more than one knee ligament is called a multiligament knee injury and may occur during sports or other physical activities.

Knee Procedures

  • KneeKnee Arthroscopy

    Knee arthroscopy is a common surgical procedure performed using an arthroscope, a viewing instrument, to diagnose or treat a knee problem. It is a relatively safe procedure and you will usually be discharged from the hospital on the same day of surgery.

  • KneeACL Reconstruction with Patellar Tendon

    Anterior cruciate ligament (ACL) reconstruction with patellar tendon is a surgical procedure that replaces the injured ACL with a patellar tendon. The goal of ACL reconstruction surgery is to tighten your knee and to restore its stability.

  • KneeACL Reconstruction Procedure with Hamstring Tendon

    Anterior cruciate ligament (ACL) reconstruction with hamstring tendon is a surgical procedure to replace the torn ACL with part of the hamstring tendon taken from your leg. The hamstring is the muscle located on the back of your thigh.
