Abstract
Patellar tendon ruptures from the tibial tuberosity are very uncommon. Various surgical techniques are described for patellar tendon ruptures from the tibial tuberosity. A 58-year-old male without any predisposing factors had pain and swelling in the right knee due to a road traffic accident. Tense swelling and ecchymosis were present around the right knee with a palpable defect over the patellar tendon and an inability to extend the right knee. An MRI report revealed avulsion of the distal patellar tendon from the tibial tubercle insertion and medial meniscus tear. Primary repair was done with a double-loaded suture anchor and augmentation was done by using a Gracilis tendon. After the months, the knee range of motion (ROM) of the patient reached up to 90 degrees, and there was no extension lag on straight leg raise. Hamstring augmentation with a primary repair is the safest and a good surgical option in elderly patients with patellar tendon ruptures from the tibial tuberosity.
Highlights
The incidence of patellar tendon rupture is less than that of rupture of the quadriceps tendon[1,2]
An acute distal patellar tendon rupture occurred in a 58-year-old male due to a road traffic accident
Various surgical techniques are described for patellar tendon ruptures from the tibial tuberosity, including end-to-end suture repair with stainless steel wires cerclage reinforcement [6], primary repair and allograft augmentation [7], primary repair with suture anchor [3], and SpeedBridge repair [8]
Summary
The incidence of patellar tendon rupture is less than that of rupture of the quadriceps tendon[1,2]. Patellar tendon ruptures from the tibial tuberosity are very uncommon [3,4]. An acute distal patellar tendon rupture occurred in a 58-year-old male due to a road traffic accident. We treated the distal patellar tendon rupture by combining repair with a suture anchor and augmentation with a Gracilis tendon. A 58-year-old male was brought to our hospital with complaints of pain, swelling, and difficulty in moving the right knee He gave a history of a road accident in which he fell from a motorcycle seven days ago. An MRI T2 image revealed avulsion of the distal patellar tendon from the tibial tubercle insertion and a medial meniscus tear (Figure 1). The patient resumed his daily routine as a farmer after six months with terminal restriction of knee flexion
