What type of joint is the patella?
synovial joint
The patellofemoral joint is a synovial joint between the condyles of the femur and the articular surface of the patella.
What categories can you use to differentiate knee pain?
Knee pain can be divided into three major categories:
- Acute injury: such as a broken bone, torn ligament, or meniscal tear.
- Medical conditions: rheumatoid arthritis, osteoarthritis, infections.
- Chronic use/overuse conditions: osteoarthritis, chondromalacia, IT band syndrome, patellar syndromes, tendinitis, and bursitis.
How does the patellofemoral joint work?
The compression forces of the patellofemoral joint are influenced by the quadriceps muscle force and the knee flexion angle. The patella acts as a pulley with the quadriceps tendon attaching to it proximally and the patellar tendon attaching to it distally transmitting the forces of the knee extensor mechanism.
What is a patellofemoral arthroplasty?
During knee replacement surgery, damaged bone and cartilage is resurfaced with metal and plastic components. Patellofemoral replacement is a type of “partial” knee replacement in which only a portion of the knee is resurfaced.
How bad is patellofemoral syndrome?
Patellofemoral pain is a painful knee condition. It’s sometimes called “runner’s knee.” It has to do with the way your kneecap (patella) moves on the groove of your thigh bone (femur). It’s most common in people who participate in high-impact activities that include jumping and running.
What movements occur at the patellofemoral joint?
As a gliding joint, the patella has movement in multiple planes. These motions include superior/inferior glide, medial and lateral glide, medial and lateral tilt, and medial and lateral rotation.
What is the purpose of the patellofemoral joint?
The patellofemoral joint is where the back of your patella (kneecap) and femur (thigh bone) meet at the front of your knee. It’s involved in climbing, walking on an incline, and several other knee movements.
What is a patellofemoral joint replacement?
Patellofemoral joint replacement, also called partial knee replacement, or unicompartmental knee replacement, is a surgical treatment option for individuals with arthritis of the knee that is confined to the patellofemoral compartment anterior aspect of the knee.
How long does a patellofemoral replacement last?
With current kneecap implants, a kneecap replacement can last for up to 20 years.
Is there a validated classification system for patellofemoral disorder?
First of all, reference must be made to a validated and organic classification system. The Lyonnaise school, over the years, has perfected a simple and organic sytem for classifying patellofemoral pathology and this classification is now internationally recognized (1). Classification of patellofemoral disorders
What kind of pain is patellofemoral pain?
Patellofemoral pain (PFP) is a common musculoskeletal-related condition that is characterized by insidious onset of poorly defined pain, localized to the anterior retropatellar and/or peripatellar region of the knee.
Where does the patellofemoral joint sit on the knee?
The patellofemoral joint is where your kneecap connects to the thigh and shin. The joint sits in front of the knee and is a complex structure of muscles, connective tissue, and bones. What causes patellofemoral pain syndrome?
How is the diagnosis of patellofemoral instability done?
Patellofemoral disorders must be approached through a correct process of diagnostic framing, performed using language that is, as far as possible, unequivocal. First of all, reference must be made to a validated and organic classification system.
