Summary
Anterior tibial tuberosity projection is not definitively linked to anterior knee pain. Radiological assessment found subjective shape unreliable, and objective measurements showed scattered data, complicating conclusions about femoro-patellar joint overloading.
Area of Science:
- Orthopedics
- Radiology
- Biomechanics
Background:
- Anterior knee pain syndromes are common.
- The role of tibial tuberosity morphology in these conditions is understudied.
- Tibial tuberosity anterior projection may influence patellofemoral joint mechanics.
Purpose of the Study:
- To investigate the relationship between tibial tuberosity anterior projection and anterior knee pain.
- To evaluate the reliability of subjective and objective assessments of tibial tuberosity morphology.
- To explore potential links between tuberosity hypoplasia and femoro-patellar joint overloading.
Main Methods:
- Morphological study of 77 knee joints using standard radiological methods.
- Classification of knees into groups with patellar syndromes and other conditions (e.g., meniscal).
- Subjective evaluation of tuberosity shape and objective measurement of anterior projection (ratio to account for skeletal size).
Main Results:
- Subjective evaluation of tuberosity shape was found to be unreliable.
- Objective measurements of anterior projection showed scattered values across morphological types.
- A definitive relationship between tuberosity hypoplasia and femoro-patellar joint overloading could not be established.
Conclusions:
- Subjective assessment of tibial tuberosity shape is not a reliable indicator for anterior knee pain.
- Objective measurement of anterior projection did not yield conclusive evidence for a direct link to femoro-patellar joint overloading.
- Future evaluations should consider the coronal plane position of the tibial tuberosity.

Bones of the Lower Limb: Femur and Patella
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 neck...
Bones of the Lower Limb: Tibia and Fibula
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...
Muscles that Move the Thigh
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...

Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
