# Subchondral insufficiency fracture of the knee: progress in the pathogenesis and treatment

## TL;DR

This paper reviews the causes and recent treatment developments for a knee condition that can lead to severe arthritis.

## Contribution

The paper provides a comprehensive summary of recent progress in understanding and treating subchondral insufficiency fractures of the knee.

## Key findings

- SIFK has unclear pathogenesis and can rapidly progress to end-stage osteoarthritis.
- Current clinical treatment often involves knee replacement due to a lack of definitive strategies.
- Recent years have seen more effective treatments proposed, though they remain unsummarized.

## Abstract

Subchondral Insufficiency Fracture of the Knee (SIFK) is a disease with unclear pathogenesis and rapid progression, it is prone to developing end-stage osteoarthritis. Due to the lack of a definitive treatment strategy for SIFK in the clinic, knee replacement is often the preferred measure. However, in recent years, as the disease has become better understood, more and more effective treatments have been proposed, but there is a lack of summarization. Therefore, this article summarizes its pathogenesis and therapeutic advances.
