Knee Anatomy

The knee is a complex joint made up of different structures including bones, tendons, ligaments and muscles. They all work together to maintain 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.

Knee Conditions

Knee 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.

Knee 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. In older people, the most common cause is a weak and fragile bone.

Knee Osteoarthritis

Osteoarthritis also called degenerative joint disease, is the most common form of arthritis. It occurs most often in older people. This disease affects the tissue covering the ends of bones in a joint (cartilage).

Knee Pain

Knee pain is a common condition affecting individuals of different 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.

Knee Sprain

Knee sprain is a common injury that occurs from overstretching of the ligaments that support the knee joint. A knee sprain occurs when the knee ligaments are twisted or turned beyond its normal range, causing the ligaments to tear.

Fractures of the Tibia

A crack or break in the tibia is referred to as a tibia fracture. It is a common injury that is usually caused by an injury or repetitive stress on the tibia.

Runner's Knee

Patellofemoral pain syndrome also called runner’s knee refers to pain under and around your kneecap. Patellofemoral pain is associated with a number of medical conditions such as anterior knee pain syndrome, patellofemoral malalignment, and chondromalacia patella.

Patellar Dislocation

Patellar dislocation occurs when the patella moves out of the patellofemoral groove, (trochlea) onto the bony head of the femur. If the kneecap partially comes out of the groove, it is called subluxation; if the kneecap completely comes out, it is called dislocation (luxation).

Patellar Instability

Any damage to the supporting ligaments may cause the patella to slip out of the groove either partially (subluxation) or completely (dislocation). This misalignment can damage the underlying soft structures such as muscles and ligaments that hold the kneecap in place. Patellar (kneecap) instability results from one or more complete or partial dislocations (subluxations).

Patellofemoral Instability

Patellofemoral instability means that the patella (kneecap) moves out of its normal pattern of alignment. This malalignment can damage the underlying soft structures such as muscles and ligaments that hold the knee in place.

Patella Fracture

The kneecap or patella forms a part of the knee joint. It is present at the front of the knee, protecting the knee and providing attachment to various muscle groups of the thigh and leg. Any breakage or damage to the kneecap is known as patella fracture.

Patellar Tendon Rupture

Patellar tendon rupture is the rupture of the tendon that connects the patella (kneecap) to the top portion of the tibia (shinbone).

Patellar Tendinitis

Patellar tendinitis, also known as "jumper's knee", is an inflammation of the patellar tendon that connects your kneecap (patella) to your shinbone. This tendon helps in extension of the lower leg.

Knee Injury

Knee infection is a serious medical condition that needs immediate treatment. Infection may occur followed by a knee replacement surgery or trauma and is usually caused by bacteria. Infection may spread to the space of the knee joint or deep layers of your knee causing serious complications.

Osteonecrosis of the Knee

Osteonecrosis is a condition in which the death of a section of bone occurs because of lack of blood supply to it. It is one of the most common causes of knee pain in older women. Women over 60 years of age are commonly affected, three times more often than men.

Anterior Knee Pain

Anterior knee pain is characterized by chronic pain over the front and center of the knee joint. It is common in athletes, active adolescents (especially girls) and overweight individuals.

Unstable Knee

The knee joint is one of the largest joints in the body. This highly complex joint has several tissues supporting and stabilizing its movement. Damage to any of the supportive structures causes instability of the knee joint.

Knee Procedures

Total Knee Replacement

Total knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn out or damaged surfaces of the knee joint is removed and replaced with an artificial prosthesis.

Computer Navigation for Total Knee Replacement

Total knee replacement surgery involves replacing the damaged surfaces of the articulating bones with artificial implants where computer navigation provides your surgeon with real-time 3-D images of your mapped knee and the surgical instruments during surgery.

Robotic Assisted Knee Replacement

Robotic-assisted knee replacement surgery is an alternative to the conventional knee replacement procedure. It is performed using robotic-arm technology that allows your surgeon to precisely perform the surgery through a smaller incision as compared to traditional surgery.

Robotic Assisted Partial Knee Surgery

Robotic-assisted partial knee surgery is an innovative alternative to the conventional surgical procedure to treat degenerative knee diseases such as osteoarthritis. It is performed using robotic-arm technology that allows your surgeon to precisely perform the surgery through small incisions.

Robotic Unicondylar Knee Replacement

A unicondylar knee replacement is a procedure to replace part of the knee joint with a prosthetic implant to relieve pain and improve the function of the joint. Advances in technology have allowed this procedure to be performed in a minimally invasive manner with robotic assistance.

Ultrasound-Guided Genicular Nerve Block

The genicular nerves are nerves surrounding your knee joint that are responsible for the transmission of pain impulses. Knee disorders causing excessive pain can be treated by blocking the genicular nerves from transmitting nerve impulses. The procedure may be performed under the guidance of ultrasound imaging.

Partial Knee Resurfacing

Partial knee resurfacing is a surgical procedure which involves resurfacing and replacement of only the diseased surface of the knee joint instead of the entire joint.

Unicondylar knee Replacement

Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement.

Revision Knee Replacement

Revision knee replacement surgery involves replacing a part or all your previous knee prosthesis with a new prosthesis. Although total knee replacement surgery is successful, sometimes the procedure can fail due to various reasons and may require a second revision surgery.

Custom Knee Replacement

Custom Knee Replacement is an advanced surgical procedure in which the damaged knee joint is replaced by a customized implant, specifically designed to match the unique size and shape of each patient’s knee.

Outpatient Total Knee Replacement

Total knee replacement is the surgical treatment for knee arthritis, where the damaged knee is removed and replaced with an artificial knee implant.

Tricompartmental Knee Replacement

Tricompartmental knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn-out or damaged surfaces of the knee joint are removed and replaced with artificial parts.

After Knee Replacement

These are certain procedures and precautions you need to follow after knee replacement surgery for a faster recovery.

Knee Osteotomy

Knee osteotomy is a surgical procedure in which the upper shinbone (tibia) or lower thighbone (femur) is cut and realigned. It is usually performed in arthritic conditions affecting only one side of your knee.

Knee Implants

Knee implants are artificial devices that form the essential parts of the knee during a knee replacement surgery. The knee implants vary by size, shape, and material. Implants are made of biocompatible materials that are accepted by the body without producing any rejection response.

Viscosupplementation

Viscosupplementation refers to the injection of a hyaluronan preparation into the joint. Hyaluronan is a natural substance present in the joint fluid that assists in lubrication. It allows the smooth movement of the cartilage-covered articulating surfaces of the joint.

Physical Therapy for Knee

Physical therapy is an exercise program that helps you to improve movement, relieve pain, encourage blood flow for faster healing, and restore your physical function and fitness level.
