Patella alta or high-riding patella refers to an abnormally high patella in relation to the femur. The patella sits high on the femur where the groove is very shallow. Here, the sides of the femoral groove provide only a small barrier to keep the high-riding patella in place.
Jul 6, 2023 · Patella alta, or a high-riding patella, describes a situation where the position of the patella is considered high. It may be idiopathic or may result secondary to a patellar tendon rupture. Epidemiology Associations. Several conditions are known to be associated with patella alta, including: idiopathic retropatellar pain 5
Patella Alta, aka high riding patella, is where the kneecap sits higher than normal on the thigh bone. This makes the knee less stable and prone to dislocation and anterior knee pain. In most cases, individuals are born with patella alta, but it can also develop secondary to a knee injury such as rupture of the patellar tendon.
Knee pain associated with patella alta (PA) can limit involvement in sport or work activities and prevent an individual from performing basic functional tasks. This case report describes the use of patellar taping to treat an individual with PA. Case Description. The patient was a 56 year-old female with bilateral knee pain associated with PA.
Apr 21, 2024 · Patella Alta, commonly referred to as a “high riding patella,” is a condition where the kneecap (patella) is positioned higher than usual on the femur. This anatomical variation can affect both athletes and non-athletes alike, leading to knee pain and mobility issues.
May 10, 2024 · Patellar instability is a condition characterized by patellar subluxation or dislocation episodes as a result of injury, ligamentous laxity or increased Q angle of the knee.
Patella alta is described as abnormally high-riding patella in relation to the femur, the trochlear groove, or the tibia with decreased bony stability. Patella alta represents an important predisposing factor for patellofemoral instability.
Jun 14, 2019 · A newer method to assess for patella alta is the patellotrochlear index (PTI), which is measured in the midsagital MRI as the ratio of the length of trochlear cartilage engaged with the patella to the patellar cartilage length . PTI of less than 12.5% suggests the presence of patella alta.
Nov 26, 2021 · Patella Alta refers to an abnormal and more proximal position of the patella in relation to the femur. When the patella is alta it leads to a delay of the patellar engagement within the groove during the early phase of flexion.
Patellofemoral pain syndrome occurs when nerves sense pain in the soft tissues and bone around the kneecap. These soft tissues include the tendons, the fat pad beneath the patella, and the synovial tissue that lines the knee joint. In some cases of patellofemoral pain, a condition called chondromalacia patella is present.
