Posterior tibial tendinopathy: what are the risk factors?

Area of Science:

• Orthopedics
• Podiatry
• Genetics

Background:

• Posterior tibial tendinopathy (PTT) is the primary cause of acquired flatfoot deformity in adults.
• Current research on PTT predominantly focuses on treatment strategies, neglecting underlying causal mechanisms.
• The multifactorial etiology of PTT involves both intrinsic and extrinsic risk factors.

Purpose of the Study:

• To critically evaluate reported etiologic factors for posterior tibial tendinopathy (PTT).
• To explore the potential role of genetic predisposition in the development of PTT.
• To identify gaps in current understanding regarding PTT etiology.

Main Methods:

• A comprehensive literature review was conducted.
• Searched English-language medical databases for studies published after 1936.
• Focused on identifying reported etiologic factors and genetic associations for PTT.

Main Results:

• No definitive consensus exists regarding the relative importance of identified PTT risk factors.
• Existing literature has not adequately considered a potential genetic basis for PTT.
• The interplay between known risk factors and genetic background remains unexplored.

Conclusions:

• Understanding the genetic component of PTT is crucial for a comprehensive risk profile.
• Investigating the interaction between genetic background and environmental/intrinsic factors is essential.
• Genetic association studies offer a novel approach to understanding PTT etiology.
