What is the patella embedded in?
tendon
The patella , most commonly referred to as the kneecap, is the largest sesamoid bone in the body. A sesamoid bone is one that is embedded in a tendon and, in the patella’s case, it exists within the quadriceps tendon.
What is patellar malalignment?
Patella malalignment syndrome is characterized by pain in the anterior portion of the knee. There can be numerous causes; however, the end result appears to be excessive lateral pressure on the patellofemoral articulation. This problem commonly affects athletes as an overuse injury.
How do you fix malalignment of the patella?
Non-surgical treatment may include physical therapy to strengthen the areas that have an effect on knee pain such as hip rotation, quadriceps, and hamstring exercises. A brace to realign the patella may also ease pain. NSAIDs (non-steroidal anti-inflammatories) can help alleviate pain and swelling during flare ups.
What causes patellar misalignment?
The primary cause of patellofemoral malalignment is an unbalanced set of forces across the patellofemoral joint causing the patella to not be centered within the trochlear groove, which is a part of the thigh or femur.
Why is the patella so important?
The patella functions to protect the knee joint, to lengthen the lever arm of the quadriceps femoris, and to increase the area of contact between the patellar ligament and the femur.
Do you keep your patella with a knee replacement?
After you receive anesthesia, your surgeon will make a cut over your knee to open it up. This cut is often 8 to 10 inches (20 to 25 centimeters) long. Then your surgeon will: Move your kneecap (patella) out of the way, then cut the ends of your thigh bone and shin (lower leg) bone to fit the replacement part.
What is malalignment of the knee?
Knee malalignment syndrome occurs when there is poor positioning between either of these joints. In knee malalignment of the patella-femur joint, the kneecap often feels like it is slipping or dislocating. This type of malalignment is also referred to as patellar instability.
What is malalignment syndrome?
Malalignment syndrome is a cluster of symptom consist of pain, joint dysfunction, muscle imbalance and postural adaptation resulted from a condition that occurs when one or more segments of the body are out of alignment.
Do you need surgery for patellar tracking disorder?
Surgery usually isn’t needed for patellar tracking disorder. You may need surgery if your kneecap dislocates after other treatments haven’t worked. There are several types of surgery that can correct a tracking problem. You and your doctor can decide which surgery is best for you.

Can you injure your patella?
An acute injury to the patella (kneecap) can happen from a blow to the knee or a fall. There may be damage to the soft tissues, such as a patellar tendon tear, or a fracture to the bone. Symptoms may include pain, swelling, or a feeling of instability or that the joint is locked.
How important is patella malalignment in the pathophysiology of patellar fasciitis?
The influence of patella malalignment has important implications since it is potent … Patella malalignment is associated with PF disease progression. Medial displacement and tilt of the patella predisposes to medial JSN progression, whilst lateral displacement is predictive of lateral JSN progression.
What is patellofemoral malalignment?
Patellofemoral malalignment: looking beyond the viewbox A clear understanding of the pathophysiology of anterior knee pain is inhibited by the use of imprecise, poorly defined, and often interchanged words, such as malalignment, patellar alignment, maltracking, subluxation, dislocation, and congruence.
What are the symptoms of patellar malalignment?
Though there are several symptoms and examinations that may help to suspect malalignment. Symptoms such as giving-way, stiffness, crepitation and tenderness should arouse suspicion for patellar malalignment, although these symptoms are shared by other conditions.
What does it mean when your patella is in the wrong position?
The normal patella should track in the groove of the femur in a relatively straight manner, but sometimes the patella can slip out of place due to injury or congenital abnormalities in the shape of the knee. This slippage may be very minor, or you may actually see that the patella is in the wrong position.
