BACKGROUND: Quadriceps tendon rupture (QTR) is an uncommon injury. In chronic QTR there may be a large defect and direct repair is not possible with sutures or transosseous anchors. There is no gold standard surgical procedure for the treatment of chronic QTR. We propose a novel technique in which the quadriceps tendon (QT) is reconstructed using a transfer of ipsilateral sartorius tendon. METHODS: Between January 2002 and April 2020, 19 patients undergoing sartorius muscle transfer for chronic QTR were prospectively recruited. The Knee Society Score (KSS), range of motion (ROM), and Medical Research Council (MRC) Scale for QT muscle strength were collected preoperatively and at a minimum of 2 years follow up. RESULTS: The mean age of our cohort was 53.4 ± 9.8 years with a female patient count of 12 (54%). The mean body mass index recorded was 28.5 ± 3.2 kg/m CONCLUSION: Satisfactory clinical outcomes of ipsilateral sartorius muscle transfer for chronic QTR can be expected a mean of 4.4 years after surgery.
