Patellar Tendon Avulsion with Tibial Tuberosity Sleeve Fragment

Abstract

Rupture of the patellar tendon is relatively rare. We report a case of patellar tendon avulsion with a tibial tuberosity sleeve fragment in pediatric patient. In pediatric patient, diagnosis is sometimes difficult due to uncompleted ossification. In the present case, which involved the presence of a small fleck of bone from tibia, we were able to attain a diagnosis using the Koshino-Sugimoto index and MRI and easily determine the optimal treatment with the use of the suture anchor and tension band wiring method.

Krackow technique in patellar tendon rupture with tibial tuberosity avulsion with anterolateral rim of tibial plateau fracture: A case report

“…Systemic illness like diabetes, chronic steroid use, quinolone treatment, chronic renal failure 1,6 may increase risk of patellar tendon rupture because of tendon degeneration. 7 This article describes the case of a simultaneous patellar tendon rupture with tibial tuberosity avulsion fracture in a middle-aged person in a road-traffic accident. We believe the mode of injury in our patient was direct impact on the knee due to accident causing tibial tubercle fracture with anterolateral rim of tibial plateau fracture with patellar tendon rupture.…”

“…Zernicke et al reported that a load of 17.5 times the body weight is required to rupture the human patellar tendon. 7 In tibial tuberosity avulsion fractures, the initial avulsion may be followed by rotation, causing tension in the surrounding soft tissues. The presence of rotation is often evident on radiographs.…”
