Tibial Tubercle Osteotomy
𦡠What Is a Tibial Tubercle Osteotomy?
A Tibial Tubercle Osteotomy (TTO) is a surgical procedure used to realign the kneecap (patella) to help it track properly during movement. Itβs often done in people who have:
Repeated kneecap dislocations
Patellar instability
Kneecap pain caused by poor alignment (patellofemoral pain syndrome)
The tibial tubercle is the bony bump on the front of your shinbone (tibia) where the patellar tendon attaches. In TTO, the surgeon cuts this piece of bone and shifts it slightly β usually inward, downward, or both β to improve how the kneecap moves.
π§ Why Is It Done?
This procedure aims to:
Reduce stress on the kneecap
Improve alignment and stability
Prevent further dislocations or damage to the joint
Relieve chronic anterior knee pain
Itβs often done together with MPFL reconstruction, especially in patients with structural issues contributing to instability.
π οΈ How Is It Performed?
A 6 cm section of bone where the patellar tendon attaches is cut and moved.
Itβs then fixed in the new position using screws or a plate and screws.
This changes the pull of the tendon to improve kneecap tracking.
π Recovery
Weight-bearing is limited for the first few weeks β crutches and a brace are usually needed.
Physiotherapy is essential to regain strength and movement.
Most patients return to normal daily activities in 2β3 months.
Full return to sports may take 4β6 months, depending on healing and rehab progress.
β οΈ Risks and Considerations
Risks include but are not limited to infection, blood clots, delayed bone healing, fracture, or irritation from the screws (which may later be removed).
Not suitable for every patient β careful assessment of your knee and imaging is required.
