Insights

Mucoid degeneration of the anterior cruciate ligament (ACL) causes knee pain. Arthroscopic surgery can treat this rare condition, with ACL resection as a last resort.

Area of Science:

  • Orthopedics
  • Radiology
  • Sports Medicine

Background:

  • Mucoid degeneration is a rare, degenerative condition affecting ligaments.
  • The anterior cruciate ligament (ACL) is crucial for knee stability.
  • Accurate diagnosis of ACL pathology is essential for effective treatment.

Observation:

  • A 39-year-old male patient presented with symptomatic knee pain and restricted flexion.
  • Magnetic Resonance Imaging (MRI) revealed characteristic findings suggestive of mucoid degeneration of the ACL.
  • The "celery stalk sign" on MRI is a key indicator of this condition.

Findings:

  • Mucoid degeneration of the ACL, while uncommon, presents a diagnostic challenge.
  • The "celery stalk sign" on MRI is pathognomonic for mucoid degeneration of the ACL.
  • This condition can lead to significant knee dysfunction and pain.

Implications:

  • Early diagnosis and appropriate management of ACL mucoid degeneration are crucial.
  • Arthroscopic debridement with volume reduction offers a viable treatment option.
  • In severe or refractory cases, ACL resection may be necessary to restore function.

Knee Joint01:23

Knee 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...

Bones of the Lower Limb: Femur and Patella01:16

Bones 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...

Muscles that Move the Leg01:23

Muscles that Move the Leg

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...

Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
