METHODSĀ :
The pre-operative radiographic examinations showed no abnormalities (Figure 1), while magnetic resonance imaging demonstrated quadriceps discontinuity and hyperintensity surrounding the insertion of the quadriceps tendon (Figure 2). On inspection, there was palpable gap on suprapatellar region (Figure 3A). On intraoperative finding we noticed huge defect of the quadriceps tendon that was surrounded by fibrotic tissues (Figure 3B-D).
