[Acute tibial tubercle avulsion fractures]

Area of Science:

• Orthopedic surgery
• Sports medicine
• Pediatric orthopedics

Background:

• Proximal tibia apophysis avulsion fractures are rare, affecting predominantly male adolescents due to sports-related stress.
• Osgood-Schlatter disease may predispose individuals to this injury.

Purpose of the Study:

• To provide an updated overview of the pathogenesis, diagnostics, and treatment of proximal tibia apophysis avulsion fractures.

Main Methods:

• Literature review of Level III and IV studies.
• Inclusion of original research findings.

Main Results:

• Predominantly affects males (97%), with Type III fractures being most common (48%).
• Surgical treatment (open reduction and internal fixation) is standard for displaced fractures.
• Excellent outcomes (95% return to prior activity level) are typical, with infrequent minor complications.

Conclusions:

• Acute proximal tibia apophysis avulsion is uncommon, with surgical fixation recommended for displaced injuries.
• Intra-articular fractures require careful assessment to avoid missed knee lesions.
• Successful treatment yields good to excellent results with rare significant complications.
