What are the names of ligaments behind the patella?

I think you're referring to the cruciate ligaments. Sounds like you tore 'em. Ouch! Peace and happy recovery to you, Bu.

coronary ligaments ???

I call mine Alan and Ralph

I believe they are tendons of the quadriceps extensor.

If you want the ones in the knee, the ACL (anterior cruciate ligament), PCL (posterior cruciate ligament), MCL (medial collateral ligament, and LCL (lateral collateral ligament). There is also the tendons and ligament that attach the muscles of the quadriceps (quadricept tendon).

ACL

Four ligaments are present in the knee joint, the medical collateral ligament, lateral collateral ligament, anterior cruciate ligament, and posterior cruciate ligament. These ligaments provide strength to the knee joint.
The medial collateral ligament is located at the inside of the knee joint. It extends from the medial femoral epicondyle to the tibia. This ligament prevents excessive abduction of the knee.

The lateral collateral ligament is located at the outside of the knee joint. It extends from the lateral femoral epicondyle to the head of the fibula. This ligament prevents excessive adduction of the knee.
The anterior cruciate ligament extends posterolaterally from the tibia and inserts on the lateral femoral condyle. This ligament prevents excessive posterior movement of the femur on the tibia.

The posterior cruciate ligament extends anteromedially from the tibia posterior to the medial femoral condyle. This ligament prevents excessive anterior movement of the femur on the tibia.

Hope this helps.
