Treatment of neglected quadriceps tendon ruptures using LARS™ ligament augmentation: A case series

Abstract

Background Late presentation of Quadriceps tendon rupture (QTR) is rare. Treatment of neglected QTR's can be challenging due to scar tissue and muscle wasting and may require augmentation. Delayed tendon repairs tend to have less favourable outcome compared to acute repairs. There are very few case reports of delayed repair using various techniques. Methods a case series of 5 patients (6 tendon ruptures) presenting late with quadriceps tendon rupture. Repair was performed using a Codivilla V—Y plasty to extend the tendon, followed by LARS artificial ligament augmentation. All patients then received 6 weeks targeted physiotherapy after wound healing. Results Repair using our technique was possible in all patients. No patients needed to return to theatre due to re-rupture or infection. Only one patient required oral antibiotics for a superficial wound infection. No patient was left with a functional deficit following physiotherapy, with 4 of the 6 repairs achieving a full range of movement. Conclusions V—Y plasty followed by LARS augmentation can be used safely and reproducibly for the repair of delayed presentation quadriceps tendon ruptures in our cohort comprising of both healthy and co-morbid patients to achieve good functional results.

Fracturas apendiculares en caninos politraumatizados, complicaciones asociadas y tratamientos actuales

“…Las fracturas que se producen como consecuencia de traumatismos severos tienen que pasar por un proceso fisiológico de recuperación, este puede tener algunas complicaciones, una de estas es el daño tendinoso-muscular (R. García et al, 2014). Los daños producidos en el mecanismo extensor ocasionan pérdidas significativas de la función, estas son frecuentes después de un traumatismo (Mahoney et al, 2021).…”
