Surgical repair of a tibialis anterior tendon rupture : a case report.

A 61-year-old man who stretched in the morning presented a rupture of the tibialis anterior tendon treated by extensor hallucis longus transfer. Rupture of the tibialis anterior tendon is rare. Surgical treatment seems to be more efficient in improving the function.

Knee size chart nomogram for evaluation of tibial tuberosity-trochlear groove distance in knees with or without history of patellofemoral instability.

Purpose: Lateralized tibial tubercle is a cause of patellar instability. Before proceeding with reduction of the tibial tubercle-trochlear groove (TT-TG) distance, surgeons prefer to know whether this distance is pathologic. However, the pathological value remains discussed and may vary with the size of the knee.

Risk of vascular injury when screw drilling for tibial tuberosity transfer.

Purpose: During tibial tubercle transfer, popliteal vessels are at risk from drills and screws. The risk is around 0.11%, as described in the literature.
