Summary
A new digital classification system based on AO classification effectively categorizes floating knee injuries. This system aids in surgical treatment planning and future clinical classification of these complex injuries.
Area of Science:
- Orthopedic Surgery
- Trauma Classification
- Digital Imaging Analysis
Background:
- Floating knee injuries represent complex trauma with varied presentations.
- Existing classification systems may not fully capture the nuances of these injuries.
- Standardized classification is crucial for effective treatment and outcome prediction.
Purpose of the Study:
- To develop and validate a digital classification system for floating knee injuries.
- To utilize the AO classification system as a basis for this new digital tool.
- To summarize injury patterns and distribution using the proposed classification.
Main Methods:
- A retrospective analysis of 100 floating knee injury cases (2005-2020).
- Application of a digital classification system derived from AO classification principles.
- Division of femur and tibia into three segments each, creating six combined injury types.
- Analysis of injury distribution and patterns based on the digital classification.
Main Results:
- The study analyzed 103 cases, categorizing them into six types.
- Type I injuries constituted the largest proportion at 42.7%.
- Injury types II through VI represented 18.4%, 9.7%, 10.7%, 11.7%, and 6.8% respectively.
Conclusions:
- The digital AO-based classification system effectively categorizes most floating knee injuries, including open fractures.
- This system provides a valuable reference for selecting surgical treatment plans.
- The proposed classification is expected to facilitate future clinical advancements in managing floating knee injuries.

01:18Classification of Bones
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
