Conditions

Knee Pain

The knee is one of the largest joints in the body, formed by the lower end of the femur, upper end of the tibia and the patella or knee cap. Several ligaments and muscles attach to the bones of the knee joint to maintain normal motion of the joint.

Baker’s Cyst

The knee consists of a fluid called synovial fluid, which reduces friction between the bones of the knee joint while you move your leg. Sometimes this fluid is produced in excess, resulting in its accumulation in the back of your knee. A Baker’s cyst or popliteal cyst is a fluid-filled swelling that develops into a lump behind the knee.

Bursitis

A bursa is a small fluid-filled sac found between soft tissues and bones. It lubricates and acts as a cushion to decrease friction between bones when they move. Bursitis refers to the inflammation and swelling of the bursa.

For more information about Bursitis, click on below tab.

Lateral Meniscus Syndrome

The knee joint is formed by the union of two bones, namely the femur (thigh bone) and the tibia (lower leg bone). At the junction of these two bones is a cartilage called the meniscus, which acts as a shock absorber. There are two menisci – the lateral and medial menisci.

For more information about Lateral Meniscus Syndrome, click on below tab.

Medial Meniscus Syndrome

Of the menisci within the knee, it is the medial that is more easily injured. Differences in the anatomical attachments of the medial meniscus compared to the lateral mean that the medial meniscus becomes distorted during combined flexion and rotation movements in a manner not experienced on the lateral side.

Knee Angular Deformities

Angular deformities of the knee are common during childhood and usually are variations in the normal growth pattern. Angular deformity of the knee is a part of normal growth and development during early childhood.

Knee Injuries

Pain, swelling and stiffness are the common symptoms of any damage or injury to the knee. If care is not taken during the initial phases of injury, it may lead to joint damage that may end up destroying your knee.

For more information about Knee Injuries, click on below tab.

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.

Ligament Injuries

The knee is a complex joint which consists of bone, cartilage, ligaments and tendons that make joint movements easy and at the same time more susceptible to various kinds of injuries.

For more information about Ligament Injuries, click on below tab.

ACL Tears

The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee that is 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.

For more information about ACL Tears, click on below tab.

PCL Injuries

Posterior cruciate ligament (PCL), one of four major ligaments of the knee are situated at the back of the knee. It connects the thighbone (femur) to the shinbone (tibia). The PCL limits the backward motion of the shinbone.

For more information about PCL Injuries, click on below tab.

MCL Tears

The medial collateral ligament (MCL) is the ligament that is located on the inner part of the knee joint. It runs from the femur (thighbone) to the top of the tibia (shinbone) and helps in stabilizing the knee. Medial collateral ligament (MCL) injury can result in a stretch, partial tear, or complete tear of the ligament.

Chondral (Articular Cartilage Defects)

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. Articular cartilage does not have a direct blood supply to it so has less capacity to repair itself.

Knee Fractures

Patella Fracture

The knee cap or patella is the largest sesamoid bone in the body and one of the components of the knee joint, present at the front of the knee. The undersurface of the kneecap and the lower end of the femur are coated with articular cartilage, which helps in smooth movement of the knee joint.

Tibial Eminence Spine Avulsions

Tibial eminence spine avulsion fracture is avulsion (tear away) of the tibial eminence (an extension on the bone for attachment of muscles) which most commonly involves the anterior cruciate ligament (ACL) insertion site.

For more information about Tibial Eminence Spine Avulsions, click on below tab.

Tibial Plateau Fracture

The tibia or shin bone is a long bone in the lower leg. Flat surfaces called medial and lateral tibial plateaus at the upper end of the tibia articulate with the femur (thigh bone) to form the knee joint. This surface is softer than the region of the tibia below.

For more information about Tibial Plateau Fracture, click on below tab.

Distal Femur Fracture

The femur or thigh bone is the longest and strongest bone in the body, connecting the hip to the knee. Distal femur fracture refers to fracture of the femur just above the knee joint. Distal femur fracture is less common than other types of femoral fractures affecting mostly elderly individuals.
