The patella is the largest sesamoid bone in the body and provides increased mechanical advantage for knee extension.
In our experiment, the sensor was sutured to the patellar tendon so that the sensor would stay underneath the patella when the knee flexed to different flexion angles.
The goal is restoration and maintenance of balance of the patella within the trochlea.
The joint is held in place by ligaments and covered at the front by the patella (kneecap).
Cartilage under the patella or kneecap wears away and the surface becomes rough and grainy.
A vertical incision is made over the pes anserinus insertion halfway between the medial border of the patella ligament and the posterior margin of the tibia.
Bone plugs from the patella and the tibial tubercle were taken in line with the incised tendon by using a small saw.
No other patient had an articular cartilage injury of the patella , trochlea, or tibia.
The patella and entire patellar tendon were left intact.
I had my knee reconstructed back in September and the surgeon took a strip from my patella to reinforce the cruciate ligament.
