Update on Patellar Instability

Area of Science:

• Orthopedics
• Sports Medicine
• Biomechanical Engineering

Background:

• Patellar instability is a common condition resulting from anatomical variations and altered patellofemoral alignment.
• It significantly impacts patient function and requires a comprehensive understanding of contributing factors.

Purpose of the Study:

• To review and synthesize current knowledge on patellar instability.
• To summarize risk factors, diagnostic criteria, and treatment options for patellar instability.

Main Methods:

• A literature review was performed using major databases: MEDLINE (via Pubmed), LILACS, and Cochrane Library.
• The review focused on identifying current concepts regarding diagnosis and management of patellar instability.

Main Results:

• Accurate diagnosis relies on detailed clinical assessment, patient history, individual risk factors, and imaging studies.
• Treatment strategies for patellar instability are debated and involve both conservative and surgical interventions.

Conclusions:

• Effective management of patellar instability necessitates a combined approach, addressing both soft tissue and bony abnormalities.
• Bone structure abnormalities are a primary indication for surgical intervention, particularly in cases of lateral patellar instability.
