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 tendon. Partial tears may be visualized using MRI scans. [4]
Patella fracture. Based on symptom, confirmed with X-rays. [3] 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] Complications may include injury to the tibia, femur, or knee ligaments. [2]
Frequency. 6 per 100,000 per year [4] 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.
The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the quadriceps femoris.
Osgood–Schlatter disease (OSD) is inflammation of the patellar ligament at the tibial tuberosity (apophysitis) [3] usually affecting adolescents during growth spurts. [5] It is characterized by a painful bump just below the knee that is worse with activity and better with rest. [3] Episodes of pain typically last a few weeks to months. [6]
Patellar tendinitis, also known as jumper's knee, is an overuse injury of the tendon that straightens the knee. [1] Symptoms include pain in the front of the knee. [1] Typically the pain and tenderness is at the lower part of the kneecap, though the upper part may also be affected. [2] Generally there is no pain when the person is at rest. [2]
The medial patellofemoral ligament (MPFL) is one of several ligaments on the medial aspect of the knee. It originates in the superomedial aspect of the patella and inserts in the space between the adductor tubercle and the medial femoral epicondyle. The ligament itself extends from the femur to the superomedial patella, and its shape is similar ...
The diagnosis is usually made clinically, but ultrasound or MRI can be used if there is any doubt. Quadriceps tendon rupture in plain X-ray: Incomplete rupture with haematoma in tendon. X-ray of a tear of the patellar tendon. On the left: The kneecap is pulled up. On the right: Significant dent in the soft tissue above the kneecap.
