Resumen
Este estudio detalla una técnica quirúrgica para la resección extrarticular amplia de la articulación de la rodilla y su reconstrucción con endoprótesis. El objetivo es lograr márgenes oncológicos adecuados preservando la extensibilidad de la articulación de la rodilla.
Área de la Ciencia:
- Oncología Ortopédica
- Reconstrucción Quirúrgica
- Oncología Musculoesquelética
Sus antecedentes:
- Los tumores de la articulación de la rodilla y las fracturas complejas plantean importantes desafíos para el salvamento de la extremidad.
- La resección extrarticular es crucial para lograr márgenes de seguridad oncológica.
- La reconstrucción endoprotésica ofrece una opción viable para la preservación de la extremidad.
Objetivo del estudio:
- Describir una técnica para la resección extrarticular amplia en bloque de la articulación de la rodilla.
- Esbozar el proceso de reconstrucción utilizando una endoprótesis de la articulación de la rodilla.
- Enfatizar la preservación de la extensibilidad de la articulación de la rodilla después de la cirugía.
Principales métodos:
- Un abordaje lateral con disección cuidadosa y osteotomías del fémur y la tibia.
- Osteotomía rotuliana y manejo de tejidos blandos para el acceso a la articulación.
- Reconstrucción utilizando una endoprótesis tumoral modular después de la extirpación del tumor.
Principales resultados:
- La técnica descrita facilita la resección tumoral amplia con márgenes adecuados.
- La reconstrucción endoprotésica permite la preservación de la extremidad y la restauración funcional.
- El manejo postoperatorio incluye carga de peso controlada y ejercicios progresivos de rango de movimiento.
Conclusiones:
- La resección extrarticular amplia combinada con la reconstrucción endoprotésica es una estrategia eficaz para los tumores de la articulación de la rodilla.
- Este enfoque tiene como objetivo equilibrar el control oncológico con la preservación funcional de la extremidad.
- La técnica quirúrgica cuidadosa y la rehabilitación postoperatoria son clave para el éxito de los resultados.

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...

01:16Structural Joints: Synovial Joints
6.5K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

01:03Structural Joints: Fibrous Joints
3.6K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

01:17Structural Joints: Cartilaginous Joints
3.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable

00:58Introduction to Joints
4.7K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...
