patella

[pətel′ə]
Etymology: L, small dish
a flat, large sesamoid bone at the front of the knee joint, having a pointed apex that attaches to the patellar ligament. The convex anterior surface of the bone is perforated for the passage of nutrient vessels and covered by an expansion from the tendon of the quadriceps femoris. Also called kneecap.

pa·tel·la

, pl. patellae (pă-tel'ă, -ē) [TA]
The large sesamoid bone that covers the anterior surface of the knee. It is formed in the tendon of the quadriceps femoris muscle and is attached to the tibia by the patellar tendon.
Synonym(s): kneecap.
[L. a small plate, the kneecap, dim. of patina, a shallow disk, fr. pateo, to lie open]

patella

The knee cap. The patella is a large triangular SESAMOID bone lying on front of the knee joint within the tendon of the QUADRICEPS FEMORIS group of muscles.

patella

  1. the kneecap bone which is present in most mammals, and in some birds and reptiles, protecting the front of the joint from injury.
  2. the generic name of the LIMPET, Patella.

A standard midline longitudinal incision from superior pole of patella to tibial tuberosity was given.
The patella is the largest sesamoid bone which ossifies from one center in 77% and from two or three centers in 23% of children.
The patella is a large seasmoid bone which develops in the tendon of quadriceps femurs muscle.
Quadriceps contracture present (on keeping the patella on trochlear fossa, flexion of knee is possible only up to 600 and on release, patella dislocated laterally and full flexion was achieved)
The incision is then extended distally by curving it around the medial patellar border to the tibial tubercle with a small (2 mm to 3 mm) margin of tissue maintained along the medial patella in order to ease subsequent closure.
When securing the graft, the patella was pushed slightly laterally to avoid medial overtensioning.
Changes of osteoarthritis graded according to Kellgren and Lawrence system--on the medial and lateral facets of the patella were noted on preoperative Merchant views (Table 1) and the tibiofemoral compartment as well.
The complication that was not noticed in present study was fragmentation of patella after patellar desmotomy as observed in significant number of equines (Tnibar, 2001 and Stashak, 1987).
Maneuvers with flexion, extension, and manual manipulation of the patella were unsuccessful in reducing the patella.
Rupture of the patellar or quadriceps tendon or a fracture of the patella itself can disrupt the extensor mechanism [3].
The incision was made from the superior pole of the patella to the medial side where the patella tendon inserts into the tibia tubercle.
