Disrupted quadriceps tendon post knee arthroplasty: A case series.

Abstract

QTR (Quadriceps Tendon Rupture) occurs rarely after TKA (Total Knee Arthroplasty) but is a severe complication which has an association with morbidity and adverse outcomes. Rare literary evidence is available which deals with the complications. Delayed management may cause adverse outcomes so the focus is on the timely management of the disease; although, the diagnosis process is full of challenges because we expect weaker quadriceps after TKA as the surgical intervention violates quadriceps muscle. In case of postoperative trauma with the outcomes of weaker extensor weakness, a USG assessment is necessary to reduce the chances of prompt QTR performance after exclusion of the fracture. We have shared our experience about the treatment of four cases of QTR in the early postoperative time with focused efforts on prevention. We can reduce the chances of rupture with meticulous surgical approaches in the course of medial parapatellar method in order to preserve quadriceps integrity.
