Summary
The normal tibio-femoral angle (TFA) in the Rajasthani population ranges from 160°-174°. Radiological measurements of TFA were significantly higher than clinical measurements, with males exhibiting larger angles than females.
Area of Science:
- Orthopaedic surgery
- Human morphology
- Biomechanical analysis
Background:
- Tibio-femoral angle (TFA) varies across populations, impacting orthopaedic surgery.
- Limited data exists on TFA within the Indian population, particularly the Rajasthani demographic.
Purpose of the Study:
- Establish baseline data for TFA in the Rajasthani population.
- Correlate clinical TFA measurements with radiological findings.
- Investigate variations based on sex and measurement method.
Main Methods:
- Cross-sectional study of 500 healthy Rajasthani subjects.
- TFA measurements taken in standing and supine positions.
- Comparison with radiological measurements from 134 subjects.
Main Results:
- Normal TFA range in Rajasthani population: 160°-174°.
- Mean standing TFA: Right 170.96°, Left 170.14°.
- Radiological TFA measurements were significantly higher (mean difference +5.78°) than clinical measurements.
- Males showed higher TFA values than females.
Conclusions:
- The study provides crucial reference data for TFA in the Rajasthani population.
- Significant discrepancies exist between clinical and radiological TFA measurements.
- Sex-based differences in TFA warrant consideration in clinical practice.

01:16Bones of the Lower Limb: Femur and Patella
3.5K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

01:10Bones of the Lower Limb: Tibia and Fibula
5.9K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

01:23Knee Joint
2.4K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

2.0K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
