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. This surface can wear out for several reasons; often the definite cause is not known. Arthritis often affects the knee joint. When the articular cartilage wears out, the bone ends rub on one another and cause pain. The most common type of arthritis is osteoarthritis. It occurs with aging and use.
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).In a person with osteoarthritis, the cartilage becomes damaged and worn out causing pain, swelling, stiffness and restricted movement in the affected joint. This condition most commonly affects the joints in the hips, knees, hands, and spine. Rarely, the disease may affect the shoulders, wrists, and feet.
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. 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. A fracture in the kneecap is rare but common in adult males.
Jumper's Knee
Jumper’s knee, also known as patellar tendinitis, is inflammation of the patellar tendon that connects your kneecap (patella) to your shinbone. This tendon helps in the extension of the lower leg.
Knee 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. A precise diagnosis of the underlying cause is important to develop an appropriate treatment plan.
PCL Injuries
Posterior cruciate ligament (PCL), one of the four major ligaments of the knee, is 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.
Stress Fracture of the Tibia
A stress fracture of the tibia or shinbone is a thin fracture, also called a hairline fracture that occurs in the tibia due to excess stress or overuse. The tibia is a weight-bearing bone in which stresses can accumulate from activities such as running and jumping.
Knee Ligament Injuries
The knee is a complex joint that consists of bone, cartilage, ligaments, and tendons that help in your joint’s movements. The knee is a hinge joint made up of two bones, the thighbone (femur) and shinbone (tibia). Ligaments are tough bands of tissue that connect one bone to another bone. The ligaments of the knee stabilize the knee joint. There are two important groups of ligaments that hold the bones of the knee joint together, collateral and cruciate ligaments - medial collateral ligament (MCL) and lateral collateral ligament (LCL), and anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL).
Meniscal Tears
There are two wedge-shaped cartilage pieces present between the thighbone and the shinbone each called a meniscus. The menisci stabilize the knee joint and act as shock absorbers.
MPFL Reconstruction
The medial patellofemoral ligament (MPFL) is a ligament that joins the kneecap (patella) to the thighbone (femur). Ligaments are fibrous connective tissue that attach bones to other bones. The MPFLis attached to the inside of the patella and helps stabilize it and position it in a groove at the lower end of the femur called the trochlea. Trauma or a blow to the knee may cause a tear in the ligament.
