What does MPTA mean in UNCLASSIFIED
MPTA stands for Medial Proximal Tibial Angle. It is an anatomical measurement used to describe the angle formed by the medial border of the proximal tibia (shin bone) and the horizontal plane. This angle is important in assessing the alignment of the lower limb and in diagnosing and treating conditions such as knee pain and osteoarthritis.
MPTA meaning in Unclassified in Miscellaneous
MPTA mostly used in an acronym Unclassified in Category Miscellaneous that means Medial proximal tibial angle
Shorthand: MPTA,
Full Form: Medial proximal tibial angle
For more information of "Medial proximal tibial angle", see the section below.
Measurement of MPTA
The MPTA is measured on a lateral (side) radiograph of the knee. A line is drawn along the medial border of the proximal tibia, and another line is drawn parallel to the horizontal plane. The angle between these two lines is the MPTA.
Normal Range of MPTA
The normal range of MPTA is 83° to 93°. A MPTA that is outside of this range may indicate an alignment issue that could contribute to knee pain or other problems.
Clinical Significance of MPTA
An increased MPTA (greater than 93°) is associated with:
- Medial knee pain
- Osteoarthritis of the medial compartment of the knee
- Varus deformity (bowleggedness)
A decreased MPTA (less than 83°) is associated with:
- Lateral knee pain
- Osteoarthritis of the lateral compartment of the knee
- Valgus deformity (knock-kneedness)
Essential Questions and Answers on Medial proximal tibial angle in "MISCELLANEOUS»UNFILED"
What is the Medial proximal tibial angle (MPTA)?
The Medial proximal tibial angle (MPTA) is an anatomical angle formed by the intersection of the medial border of the proximal tibia and a line drawn perpendicular to the tibial axis. It is a commonly measured angle in orthopedic surgery, especially in the context of knee alignment and ligament reconstruction.
How is the MPTA measured?
The MPTA is typically measured on a lateral radiograph of the knee. The angle is formed by the intersection of a line drawn along the medial border of the proximal tibia and a line drawn perpendicular to the tibial axis. The tibial axis is defined as the line connecting the center of the knee joint to the center of the ankle joint.
What is the normal range for the MPTA?
The normal range for the MPTA varies slightly depending on the population being studied. In general, the average MPTA is around 87 degrees, with a range of approximately 83-91 degrees.
What factors can affect the MPTA?
Several factors can affect the MPTA, including:
- Age: The MPTA tends to decrease with age.
- Gender: Males typically have a slightly larger MPTA than females.
- Race: There are some variations in the MPTA among different racial groups.
- Ligament injuries: Injuries to the medial collateral ligament (MCL) can lead to an increase in the MPTA.
What is the clinical significance of the MPTA?
The MPTA is a useful measurement for assessing knee alignment and ligament stability. It can be used to diagnose and monitor conditions such as:
- Medial knee instability: An increased MPTA may indicate medial knee instability, which can be caused by MCL injuries.
- Osteoarthritis: Changes in the MPTA can be associated with the development and progression of osteoarthritis in the knee.
Final Words: The MPTA is an important anatomical measurement that can provide valuable information about the alignment of the lower limb. Abnormalities in the MPTA may indicate underlying conditions that require further evaluation and treatment.
