Summary

This summary is machine-generated.

A new knee plica variant, the extended medial coronal plane plica (EMCPP), was identified. Excision may relieve symptoms but can complicate total knee arthroplasty (TKA) due to scarring.

Area Of Science

  • Orthopedic Surgery
  • Anatomy
  • Radiology

Background

  • The knee joint's complex anatomy includes synovial plicae, which can cause symptoms when inflamed or hypertrophied.
  • Recent literature has described new plica variants in the coronal plane.
  • Understanding plica variations is crucial for diagnosing knee pain and planning surgical interventions.

Observation

  • A previously unreported variant, the extended medial coronal plane plica (EMCPP), was observed in a 70-year-old female patient.
  • The patient presented with knee osteoarthritis and a loose body, experiencing temporary symptom relief after plica and loose body excision.
  • Despite initial relief, the patient later required total knee arthroplasty (TKA) for progressive osteoarthritis.

Findings

  • The extended medial coronal plane plica (EMCPP) is a novel anatomical finding in the knee.
  • Surgical excision of the EMCPP can provide temporary symptom relief for specific knee conditions.
  • Internal scarring or the plica itself post-excision may present challenges during subsequent TKA procedures.

Implications

  • Recognition of the EMCPP variant is important for accurate diagnosis and surgical planning in knee disorders.
  • The potential for internal scarring after EMCPP excision could impact the feasibility and outcome of total knee arthroplasty.
  • Further research is warranted to elucidate the clinical significance and long-term effects of this plica variant.

Bones of the Lower Limb: Femur and Patella 01:16

2.4K

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...

Knee Joint 01:23

1.7K

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...

Muscles that Move the Leg 01:23

1.6K

The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Muscles that Move the Thigh 01:20

The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Bones of the Lower Limb: Tibia and Fibula 01:10

3.2K

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
