The patella can also be fractured indirectly. For example, a sudden contraction of the quadriceps muscle in the knee can pull apart the patella. [1] Diagnosis is based on symptoms and confirmed with X-rays. [3] In children an MRI may be required. [3] Treatment may be with or without surgery, depending on the type of fracture. [2]
If the tendon rupture is a partial tear (without the two parts of the tendon being separated), then non-surgical methods of treatment may suffice. The future of non-surgical care for partial patella tendon ruptures is likely bioengineering. Ligament reconstruction is possible using mesenchymal stem cells and a silk scaffold. [5]
Printable version; In other projects ... A quadriceps tendon rupture is a tear of the tendon that runs from the quadriceps muscle to the top of the knee cap. [1 ...
The bones of the knee are the femur, patella, tibia, and fibula. The fibula is on the lateral side of the knee and the patella has little effect on the medial side of the knee. The bony congruity of the medial knee consists of the opposing surfaces of the medial femoral condyle and the medial tibial plateau.
[1] [2] In those who are otherwise healthy, treatment is generally by surgery. [1] Occasionally, if the bones are well aligned and the ligaments of the knee are intact, people may be treated without surgery. [2] They represent about 1% of broken bones. [2] They occur most commonly in middle aged males and older females. [3]

Femur with Q angle: the angle formed by a line drawn from the anterior superior iliac spine through the center of the patella and a line drawn from the center of the patella to the center of the tibial tubercle. Some studies have suggested that there are four neuromuscular imbalances that predispose women to higher incidence of ACL injury.
Surgery after a first dislocation is generally of unclear benefit. [6] [4] Surgery may be indicated in those cases where a fracture occurs within the joint or where the patella has repeatedly dislocated. [3] [4] [5] Patellar dislocations occur in about 6 per 100,000 people per year. [4] They make up about 2% of knee injuries. [1]
