Tibial Tubercle Transposition

Tibial Tubercle Transposition

What is Tibial Tubercle Transposition?

Tibial tubercle transposition is a surgical procedure performed to improve the alignment and tracking of the kneecap (patella). The procedure involves repositioning the tibial tubercle, which is the bony attachment site of the patellar tendon on the shinbone. By adjusting the position of this attachment point, the surgeon can help reduce abnormal pressure on the kneecap and improve knee stability. Tibial tubercle transposition is commonly recommended for patients with recurrent patellar instability, patellar maltracking, or cartilage damage related to improper kneecap alignment.

What are the Benefits of Tibial Tubercle Transposition?

Tibial tubercle transposition may provide several benefits for patients experiencing chronic kneecap instability or pain.

Benefits may include:

• Improved patellar alignment and tracking
• Reduced risk of recurrent kneecap dislocation
• Decreased knee pain during activity
• Improved knee stability
• Reduced pressure on damaged cartilage
• Enhanced function during sports and daily activities
• Better long-term knee mechanics

When is Tibial Tubercle Transposition Recommended?

This procedure may be recommended when conservative treatments fail to relieve symptoms or when structural alignment problems contribute to ongoing instability.

Tibial tubercle transposition may be recommended for:

• Recurrent patellar dislocations
• Chronic patellar instability
• Patellar maltracking
• Cartilage damage behind the kneecap
• Patellofemoral pain syndrome
• Abnormal kneecap alignment
• Failed non-surgical treatment options

What Does Preparation for Tibial Tubercle Transposition Involve?

Preparation for tibial tubercle transposition typically begins with a detailed orthopedic evaluation, imaging studies, and a review of the patient’s symptoms and activity level. X-rays, MRI scans, or CT scans may be used to assess kneecap alignment and cartilage damage. Patients may be asked to stop certain medications prior to surgery and arrange for assistance during the initial recovery period. Preoperative instructions regarding fasting, bracing, and rehabilitation planning are also discussed before the procedure.

How is Tibial Tubercle Transposition Performed?

During the procedure, the surgeon makes an incision over the front of the knee and carefully cuts and repositions the tibial tubercle to improve kneecap alignment. The bone segment is then secured in its new position using surgical screws or fixation devices. In some cases, additional procedures such as cartilage restoration or ligament reconstruction may be performed at the same time to further improve knee stability and function.

What to Expect During Recovery After Tibial Tubercle Transposition?

Recovery following tibial tubercle transposition typically involves a structured rehabilitation program focused on restoring motion, strength, and stability. Patients may initially use crutches and a knee brace while the bone heals. Physical therapy plays an important role in recovery and gradual return to activity. Swelling and discomfort are common during the early healing phase, but most patients experience progressive improvement over several months.

What are the Risks and Complications of Tibial Tubercle Transposition?

As with any surgical procedure, tibial tubercle transposition carries certain risks and potential complications.

Possible risks and complications include:

• Infection
• Bleeding
• Blood clots
• Knee stiffness
• Persistent pain
• Delayed bone healing
• Hardware irritation
• Recurrent instability
• Nerve or blood vessel injury
• Need for additional surgery
