What is a calcified fabella?
The fabella is a small sesamoid bone found in some mammals embedded in the tendon of the lateral head of the gastrocnemius muscle behind the lateral condyle of the femur. It is an accessory bone, an anatomical variation present in 39% of humans. Rarely, there are two or three of these bones (fabella bi- or tripartita).
How is fabella syndrome treated?
Fabella pain syndrome can be treated with physical therapy, injection of local anesthetics or steroids near the site, radial extracorporeal shock wave therapy (rESWT) or fabellectomy [6]. Physical therapy entails the patient be placed in a prone position with the legs supported at an angle of 30 degrees flexion [15].
Is patella a sesamoid bone?
The patella is a sesamoid bone located in the major extensor tendon of the knee joint, in the hindlimb of many tetrapods.
Can a fabella be removed?
After the arthroscopic visualization of the fabella along with assessment of damage to the surrounding structures, the fabella is excised. The use of the arthroscopic procedure allows for excision of this sesamoid bone with minimal resection, thereby decreasing the risk of injury to surrounding tissue.
What is a knee fabella?
The fabella is a sesamoid bone in the posterolateral capsule of the human knee joint. The presence of the fabella in humans varies widely and is reported in the literature to range from 20% to 87% [1-7]. The fabella is located in the posterior aspect of the knee where lines of tensile stress intersect.
What is the fabella bone?
The fabella is a sesamoid bone that is embedded in the lateral head of the gastrocnemius muscle and often articulates directly with the lateral femoral condyle. It is present in 10-30% of the general population with a higher incidence in Asians.
How do I know if I have fabella bone?
Medical professionals search for the fabella bone by palpating at the back of the knee and checking for swelling or tenderness in the surrounding area. If they believe the fabella is indeed the reason, an ultrasound or magnetic resonance imaging (MRI) is used to confirm their diagnosis.
How common is fabella syndrome?
The presence of the fabella in humans varies widely and is reported in the literature to range from 20% to 87% [1-7]. The fabella is located in the posterior aspect of the knee where lines of tensile stress intersect.
Is fabella normal?
The fabella is a sesamoid bone in the posterolateral capsule of the human knee joint. The presence of the fabella in humans varies widely and is reported in the literature to range from 20% to 87% [1-7].
How can you tell if you have fabella?
Examination. Physical examination may reveal the presence of swelling/tenderness in the posterolateral aspect of the knee. Palpation of the fabella may suggest the presence of a firm nodule in the left posterolateral popliteal fossa, medial to the tendon of the biceps femoris, and approximately 1 cm in diameter.
