Summary
Rotating hinge knee prostheses are increasingly used for complex knee conditions. A rare failure case highlights the risk of medial collateral ligament insufficiency, suggesting surgical modifications to prevent complications.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Rotating hinge knee prostheses are advanced implants used for severe knee instability or bone defects.
- These prostheses are often employed as salvage procedures in complex orthopedic cases.
- Modern implant designs have increased the application frequency of rotating hinge knee systems.

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 Patella
4.7K
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...
