A patellar dislocation, also known as a patella dislocation, occurs when the patella, or the kneecap, slips out of its normal position. The patella typically rests in a groove, known as the trochlear groove at the end of the thigh bone (femur). It is primarily held in place by two main structures: the medial patellofemoral ligament and the ...
The tibia and fibula are the two long bones in the leg that articulate with the femur to form the knee joint. The bones of the foot provide support for the body weight and enable walking, running, and other forms of locomotion. Patellar Dislocation: What Is It, Causes, Diagnosis, Treatment, and More.
Patellar tendon ruptureis a rupture of the tendonthat connects the patellato the tibia. The tell-tale sign of a ruptured patella tendon is the movement of the patella further up the quadriceps. When rupture occurs, the patella loses support from the tibia and moves toward the hip when the quadriceps musclecontracts, hindering the leg's ability ...
Chondromalacia patellae is a radiologic diagnosis characterized by pathologic wear and tear of smooth cartilage underneath the patella and the term is used interchangeably with patellofemoral pain syndrome. Chondromalacia patellae can be caused by weakness of the core and thigh muscles; recurrent joint injuries or trauma such as repetitive ...

Summary. Osgood-Schlatter disease is a common condition that affects the knee in adolescents, typically during the growth spurt that occurs just before puberty. It is caused by repetitive traction of the patella ligament on the tibial tuberosity, causing it to become inflamed, which results in a painful swelling just under the knee.
Anterior drawer test. With the patient supine, flex the patient’s knee to 90º and place their foot flat on the table. Stabilize the ankle with your hip and pull the proximal tibia anteriorly (toward you). This test assesses for a tear of the anterior cruciate ligament (ACL). Joint laxity indicates a positive test.
Calcaneal or heel spurs are bone growths that typically occur at the bottom of the heel bone. They represent the body ’s response to inflammation of a tendon or ligament at its attachment point to the bone and are usually associated with plantar fasciitis. Although heel spurs are painless, they can result in heel pain when pressing on ...
A Salter-Harris fracture refers to a injury, or fracture, through the growth plate of a long bone. Examples of a long bone are the humerus in the arm and the tibia in the leg. Present in children, the growth plate, also called the physeal or epiphyseal plate, is an area of cartilage that actively develops into new bone, increasing the bone’s ...
Legg-Calvé-Perthes disease, or LCPD, and slipped capital femoral epiphysis, or SCFE for short, are distinct hip conditions that commonly cause limp in children. In LCPD, a disrupted blood supply causes deformation of the femoral head and subsequently leads to osteonecrosis. On the other hand, in SCFE, a weakness of the growth plate causes ...
