*'''Lateral Patellar Ligament'''

*'''Lateral Patellar Ligament'''

The lateral patellar ligament attaches to the cranio-lateral aspect of the [[Hindlimb - Anatomy & Physiology#Patella|patella]] and to the lateral aspect of the [[Bones and Cartilages - Horse Anatomy#Tibia and Fibula|tibial tuberosity]]. This arrangement is crucial for the equine [[Stay Apparatus - Horse Anatomy#Pelvic Limb|stay apparatus]] and provides a '''locking ability'''. This ligament contains tendinous tissue from the ''biceps femoris'' and ''tensor fasciae latae'' muscles.

*'''Medial Patellar Ligament'''

*'''Medial Patellar Ligament'''

The medial patellar ligament connects the parapatellar fibrocartilage to the medial aspect of the [[Bones and Cartilages - Horse Anatomy#Tibia and Fibula|tibial tuberosity]] . This ligament  contains tendinous elements of the ''sartorius'' and ''gracilis'' muscles.

Contraction of the quadriceps while in rest enables the [[Hindlimb - Anatomy & Physiology#Patella|patella]]  to be hooked over the trochlea of the [[Bones and Cartilages - Horse Anatomy#Femur|femur]] due to the binding loop formed by the patella, middle and medial patellar ligaments.  The '''femeropatellar joint''' capsule sometimes communicates with the '''lateral femerotibial''' cavity and usually with the '''medial'''. No communication exists between the femorotibial joints.
