What is Retropatellar osteoarthritis?
Abstract. Retropatellar arthrosis produces painful malfunction of the patellofemoral joint. The pressure of the patella on the femoral condyles is a function of the flexion of the knee joint.
Does patellofemoral pain syndrome go away?
Left untreated, patellofemoral pain syndrome generally gets worse over time. If you continue using the affected knee without treatment, you may cause further injury.
What is Retropatellar?
Patellofemoral pain syndrome can be defined as retropatellar or peripatellar pain resulting from physical and biochemical changes in the patellofemoral joint. It should be distinguished from chondromalacia, which is actual fraying and damage to the underlying patellar cartilage.
What is lateral facet syndrome?
Lateral patellar compression syndrome refers to pain under and around your kneecap. It is a common complaint among runners, jumpers, and other athletes such as skiers, cyclists, and soccer players. The patella, also called kneecap, is a small flat triangular bone located at the front of the knee joint.
What is the difference between osteoarthritis and osteoarthrosis?
In short, “osteoarthritis” means inflammation of the joint, while “osteoarthrosis” means degeneration of the joint.
What happens to the cartilage on the retropatellar facet?
Pathologically, in the initial stage the cartilage on the retropatellar facet undergoes softening and swelling, in the second and third stages fissuring and fibrillation with a “crab meat” appearance, and in the final stage thinning and ulceration. As a result, the subchondral bone becomes exposed (Wiles et al. 1956).
What causes pressure on the lateral patella facet?
Chronic anterior knee pain with a stable patella is often associated with overload and increased pressure on the lateral facet due to pathologic lateral soft-tissue restraints. “Lateral pressure in flexion” is a term describing the pathologic process of increasing contact pressure over the lateral patellar facet as knee flexion progresses.
How is patellofemoral pain syndrome related to overuse?
Because bending the knee increases the pressure between the patella and its various points of contact with the femur, patellofemoral pain syndrome is often classified as an overuse injury.4–8 However, a more appropriate term may be “overload,” because the syndrome can also affect inactive patients.
When does retropatellar chondropathy change to osteoarthritis?
In the last stage, chondropathy has completely changed to osteoarthritis. The cartilage is then almost completely gone and the two bone ends are exposed. In the case of retropatellar chondropathy, the layer of cartilage deteriorates at the back of the kneecap.
