A patella fracture is a break of the kneecap. [1] Symptoms include pain, swelling, and bruising to the front of the knee. [1] A person may also be unable to walk. [1]

Patellar tendon rupture can usually be diagnosed by physical examination. The most common signs are: tenderness, the tendon's loss of tone, loss of ability to raise the straight leg and observation of the high-riding patella. Radiographically, patella alta can be detected using the Insall and Salvati method when the patella is shorter than its ...
A patellar dislocation is a knee injury in which the patella (kneecap) slips out of its normal position. [5] Often the knee is partly bent, painful and swollen. [1] [2] The patella is also often felt and seen out of place. [1] Complications may include a patella fracture or arthritis. [3]
Bipartite patella is a condition where the patella, or kneecap, is composed of two separate bones. Instead of fusing together as normally occurs in early childhood, the bones of the patella remain separated. [1] The condition occurs in approximately 1–2% of the population [2] [3] and is no more likely to occur in males than females.
Patella, its tendon and tibial tuberosity. The condition is usually seen in athletic individuals typically between 10 and 14 years of age. Following a strain or partial rupture of patellar ligament the patient develops a traction ‘tendinitis’ characterized by pain and point tenderness at the inferior (lower) pole of the patella associated with focal swelling.
The patella rests in the trochlear, which is found in the distal part of the femur. The patella can dislocate from the groove because of trauma or an unnatural twisting of the knee. [5] When dislocated, the soft tissue layer that the patella rests in is damaged; the patella is forced out of its groove and back into place.
CT angiogram 3D reconstruction, posterior view showing a normal artery on the left, and occlusion to right popliteal artery as a result of a knee dislocation [10] Symptoms include knee pain. [2] The joint may also have lost its normal shape and contour. [2] A joint effusion may, or may not, be present. [2]
