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...
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...
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...

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine

Context:

  • Patellar dislocation is a severe knee injury affecting athletes.
  • Surgical intervention is often required for treatment.

Purpose:

  • To evaluate the outcomes of arthroscopic surgery for patellar dislocation in athletes.
  • To assess the impact on return to sport and activity levels.

Summary:

  • A retrospective study analyzed 24 athletes (mean age 19.3) undergoing arthroscopic surgery for patellar dislocation.
  • Surgical treatment involved medial retinaculum suturing, with lateral release in 12 patients.
  • The reoccurrence rate was 12.5%, with an average Lysholm score of 83.4.
  • 45.8% returned to pre-trauma sport levels, while 37.5% ended their careers.

Impact:

  • Arthroscopic surgery can lead to good functional outcomes, but career-ending consequences are significant.
  • Athletes require comprehensive information regarding the seriousness of patellar dislocation and lengthy rehabilitation.
  • The study provides insights into the long-term prognosis for athletes after surgical patellar stabilization.
