Complications of Tibial Tuberosity Osteotomy

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Surgical Complications

Background:

• Tibial tuberosity osteotomy (TTO) is a common orthopedic procedure.
• Understanding potential complications is essential for patient safety and successful outcomes.

Purpose of the Study:

• To review and summarize the potential complications associated with tibial tuberosity osteotomies (TTOs).
• To provide guidance on how to avoid or mitigate these surgical risks.

Main Methods:

• Literature review of studies reporting complications after TTO.
• Analysis of risk factors and preventative measures for identified complications.

Main Results:

• TTO carries risks including tibial fracture (1-3%), nonunion (1%), painful hardware (3-77%), recurrent instability (~5%), deep vein thrombosis (4%), and wound complications (~1%).
• Smaller, countersunk screws and meticulous soft tissue handling can reduce specific risks.
• Severe complications like compartment syndrome and pulmonary embolism are rare.

Conclusions:

• While TTO is generally safe, awareness of potential complications is vital.
• Adherence to specific surgical techniques can minimize risks such as fracture, hardware irritation, and DVT.
• Proactive management strategies are key to optimizing TTO outcomes and patient recovery.
