Summary
Distal closing-wedge femoral osteotomy effectively corrects alignment, with most patients achieving bone healing within 6 weeks. This surgical technique sustained proposed correction in patients up to 15 years post-operation.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Distal femoral deformities can lead to knee osteoarthritis and pain.
- Surgical correction aims to restore neutral alignment and improve function.
Purpose of the Study:
- To detail the surgical technique of distal closing-wedge femoral osteotomy.
- To present a case series evaluating the outcomes of this procedure.
Main Methods:
- Retrospective review of 26 patients undergoing medial closing-wedge distal femoral osteotomy (2002-2013).
- Evaluation of medical files and imaging for correction degree and patient status.
- Assessment of bone healing, complications, and long-term outcomes.
Main Results:
- Achieved neutral alignment in all cases.
- Most patients exhibited bone healing by 6 weeks.
- Low complication rates including superficial infection and device discomfort; no deep vein thrombosis or pulmonary embolism.
- No conversion to total knee replacement observed.
Conclusions:
- Medial closing-wedge distal femoral osteotomy is a viable technique for correcting distal femoral deformities.
- The procedure demonstrated sustained correction for up to 15 years of follow-up.
- The technique offers a safe and effective option for managing specific knee alignment issues.

A wedge is a simple machine that serves various purposes, such as adjusting the elevation of structural or mechanical parts, providing stability for heavy objects, and splitting a body into two parts. This versatile tool can amplify an applied force, making it easier to manipulate large or heavy objects.
Consider using a wedge to lift a heavy slab. Here, the wedge functions by converting the applied force into a much larger force directed almost perpendicular to the initial force. This...

Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...

Friendship formation is a dynamic process shaped by psychological, cultural, and social factors. Friendships play a crucial role in emotional well-being, social development, and personal identity from childhood to adulthood.Childhood and Early FriendshipsFriendships in childhood often arise due to shared environments, such as school or neighborhood interactions. At this stage, proximity and common interests serve as the primary basis for connection. As children grow, their friendships evolve...

Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Understanding the maximum and minimum values of a function is essential for analyzing its overall behavior. These values, often referred to as extrema, provide insight into how a function behaves across its domain. In mathematical terms, extrema can be either local—representing peaks and valleys within a limited region—or absolute, indicating the highest or lowest points over an entire interval.A function’s extrema occur at critical numbers, which are values in the domain...
