Sequential bilateral quadriceps tendon rupture in a young individual with chronic kidney disease.

Quadriceps tendon rupture (QTR) is a rare but debilitating condition that impairs knee extension, crucial for gait. It typically affects the elderly but may occur in younger individuals with systemic comorbidities such as chronic kidney disease (CKD). We report a case of sequential bilateral QTRs in a young male with CKD. The patient initially presented with left knee pain, swelling and extension lag. Imaging confirmed a full-thickness quadriceps tendon tear, which was surgically repaired using two double-loaded titanium suture anchors, followed by an uneventful recovery. Seven months later, he sustained a similar injury to the right knee. MRI confirmed a full-thickness avulsion tear and the same surgical technique was applied. At a 14-month follow-up, the patient achieved full, pain-free range of motion and improved functional outcomes in both knees. This case highlights the rarity of bilateral sequential ruptures and demonstrates successful management using suture anchor fixation and a structured rehabilitation programme.
