Knee Joint01:23

Knee Joint

3.4K
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 Patella

8.2K
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...

Ankle Joint01:10

Ankle Joint

3.4K
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...

Muscles that Move the Leg01:23

Muscles that Move the Leg

6.9K
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...

Summary
This summary is machine-generated.

The GUEPAR hinge knee prosthesis showed complications like patellar displacement and loosening, necessitating re-operation in some cases. Adding a patellar prosthesis improved pain outcomes, but overall use should be limited to specific situations.

Area of Science:

  • Orthopedic surgery
  • Biomaterials science

Background:

  • The GUEPAR hinge knee prosthesis was evaluated for early and late outcomes.
  • A series of 184 operations performed before January 1, 1974, were analyzed.

Purpose of the Study:

  • To assess the efficacy and complications of the GUEPAR hinge knee prosthesis.
  • To identify factors influencing patient outcomes and recommend improvements.

Main Methods:

  • Retrospective analysis of 184 GUEPAR hinge knee prosthesis cases.
  • Evaluation of complications including patellar displacement, infection, and loosening.
  • Assessment of functional results with a 5-to-8-year follow-up for 99 patients.

Main Results:

  • Patellar displacement occurred in 27% of cases, often causing pain and instability.
  • Deep infections occurred in 8.3% of cases, with healing achieved through revision or arthrodesis.
  • Loosening occurred in 16% of cases, primarily due to inadequate technique, requiring re-operation in 6% of patients.
  • Late functional results showed 60% excellent or good outcomes, 29% fair, and 11% poor.
  • Addition of a patellar prosthesis was effective in managing pain.

Conclusions:

  • The GUEPAR hinge knee prosthesis has significant complication rates, including patellar displacement and loosening.
  • Addition of a patellar prosthesis is advisable to address pain.
  • The use of this prosthesis should be restricted to specific cases.
  • Recommendations for preventing complications include using a patellar prosthesis, reinforced models, and cementing under pressure.
