Summary
A rare suprapatellar plica, a remnant of embryonic tissue, can cause knee swelling. This case highlights a check-valve mechanism leading to this uncommon presentation.
Area of Science:
- Orthopedics
- Embryology
- Knee Anatomy
Background:
- The suprapatellar plica is a synovial membrane remnant.
- Pathologic synovial plica is an uncommon condition.
- It can present with varied clinical symptoms.
Observation:
- A case of pathologic suprapatellar plica is presented.
- This plica exhibited a check-valve mechanism.
- The mechanism resulted in knee joint swelling.
Findings:
- The check-valve mechanism in the suprapatellar plica causes fluid to be trapped.
- This leads to recurrent or persistent knee joint effusion.
- The condition mimics other causes of knee swelling.
Implications:
- Understanding this mechanism aids in diagnosing knee swelling.
- It highlights the importance of considering embryologic remnants in knee pathology.
- Accurate diagnosis can lead to appropriate treatment for suprapatellar plica syndrome.

01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
