The patella Flashcards
What is function of the patella?
The patellar has two main functions
Leg extension- enhances the leverage of the quadriceps tendon
Protection- Protects the anterior aspect of the knee joint from physical trauma
What causes a patellar dislocation
High force impacts, forceful sudden twisting of the knee. Sports such as football,rugby and ice hockey
What occurs during a patella fracture
Direct trauma or sudden contraction of the quadriceps muscle. Typically fractures causes a proximal and distal fragment
Describe the anatomy of the patella
The patella is Triangular shaped with anterior and posterior surfaces.
The Apex of the patella is situated inferiorly and connects to the tibial tuberosity via the patella ligament.
The Base forms superior aspect and attachment point for quadriceps tendon
On the posterior aspect the patella articulates with the medial condyle of the femur,
The lateral facet articulates with the lateral condyle of the femur.
