Insights

A rare large symptomatic medial meniscus cyst with a posterior horn tear was diagnosed using MRI. Arthroscopic partial meniscectomy and open cystectomy effectively treated this knee condition.

Area of Science:

  • Orthopedic Surgery
  • Knee Anatomy
  • Diagnostic Imaging

Background:

  • Meniscal cysts are rare intra-articular or extra-articular masses.
  • Symptomatic medial meniscus cysts can cause significant knee pain and dysfunction.
  • Combined meniscal tears and cysts present diagnostic and therapeutic challenges.

Observation:

  • A large symptomatic medial meniscus cyst was identified.
  • The cyst was conjoined with a horizontal tear of the posterior meniscal horn.
  • Clinical, radiological, and ultrasound examinations preceded MRI confirmation.

Findings:

  • Magnetic Resonance Imaging (MRI) confirmed the diagnosis of a medial meniscus cyst with a posterior horn tear.
  • Literature recommends arthroscopic surgery, including meniscectomy and cyst decompression.
  • The presented case utilized arthroscopic partial meniscectomy and open cystectomy for treatment.

Implications:

  • Arthroscopic partial meniscectomy combined with open cystectomy offers an effective treatment strategy for large symptomatic medial meniscus cysts with meniscal tears.
  • This approach addresses both the cyst and the associated meniscal pathology.
  • Accurate diagnosis via MRI is crucial for planning appropriate surgical intervention.

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 group...
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 neck...
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 to...
