RETINACULUM PATELLAE Meaning and
Definition
-
The term "retinaculum patellae" refers to a fibrous band or ligament located in the knee joint, specifically on the front aspect of the knee. It is commonly known as the patellar retinaculum or patellar ligament. The retinaculum patellae is composed of strong connective tissue and functions to hold the patella (kneecap) securely in place.
The retinaculum patellae consists of two parts: the medial patellar retinaculum and the lateral patellar retinaculum. The medial part is located on the inner side of the knee and attaches the patella to the tibia, while the lateral part is situated on the outer side and connects the patella to the fibula. Together, these bands provide stability to the knee joint and prevent excessive lateral movement of the patella during knee flexion and extension.
In addition to stabilizing the patella, the retinaculum patellae also plays a crucial role in transmitting forces between the thigh muscles (quadriceps) and the lower leg. During activities such as walking, running, or jumping, the retinaculum patellae acts as a mechanism for the transfer of muscular forces from the quadriceps muscles to the lower leg, facilitating movement and ensuring proper alignment.
In summary, the retinaculum patellae is a fibrous band in the knee joint that holds the patella in place and provides stability during knee movement. It also facilitates the transmission of forces between the thigh and lower leg muscles, enabling efficient motion and alignment of the knee joint.

One of several fibers of insertion of the vastus lateralis (r. patelloe laterale) or of the vastus medialis (r. patelloe mediale) which run past the patella on either side to be inserted into the condyle of the tibia.

Etymology of RETINACULUM PATELLAE
The word "retinaculum patellae" has its etymology rooted in Latin.
- "Retinaculum" derives from the Latin word "retinere", meaning "to hold back" or "to restrain". It is a noun that refers to a band, ligament, or structure that secures or holds something in place.
- "Patellae" is the genitive form of the Latin word "patella", which translates to "kneecap".
Therefore, "retinaculum patellae" literally translates to "the restraining band/ligament of the kneecap". It is a term used in anatomy to refer to a fibrous band that holds the kneecap in its position within the knee joint.
