Summary
The GSB Knee joint prosthesis offers benefits of both surface and constrained hinge designs. This study reviews outcomes and complications from 150 knee replacement surgeries over five years.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Arthroplasty
Background:
- The GSB Knee joint is a novel prosthesis design.
- It aims to integrate advantages of condylar (surface) and constrained hinge joint prostheses.
- This design seeks to improve upon existing knee replacement technologies.
Purpose of the Study:
- To evaluate the clinical outcomes of the GSB Knee joint prosthesis.
- To identify and analyze complications associated with this specific knee arthroplasty.
- To assess the efficacy of the GSB Knee joint over a defined period.
Main Methods:
- A retrospective review of 150 knee arthroplasties using the GSB Knee joint.
- Data collection focused on surgical results and observed complications.
- Follow-up period covered observations over a 5-year span.
Main Results:
- The GSB Knee joint demonstrated a combination of features from surface and hinge designs.
- Observations included both successful outcomes and various complications.
- Detailed results and complication rates were recorded for the 150 procedures.
Conclusions:
- The GSB Knee joint represents a hybrid approach in knee arthroplasty.
- The study provides valuable insights into the performance and potential issues of this implant.
- Further research may be warranted based on these 5-year observations.

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 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...

Method of Joints
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...

Method of Joints: Problem Solving I
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint. Consider a truss structure with two forces of 20 N and 10 N acting at joints C and D, respectively. The method of joints can be used to determine the forces FCB, FDC,...
Method of Joints: Problem Solving II
Consider a truss structure with frictionless joints fixed to a wall and roller support. If a force of 150 N is applied to joint A, the forces in each member of the truss can be determined using the method of joints.
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...
