Early patellar tendon rupture after total knee arthroplasty: A direct repair method

Figure 1 Locked fashion on the medial and lateral aspect of the quadriceps tendon. A and B: First we used two No. 5 non-absorbable sutures running in a locked fashion on the medial and lateral aspect of the quadriceps tendon, and sutured through two bone channels drilled longitudinally from the patella to both sides of the patellar tendon; C: Then we sutured the extensor mechanism to both tissues and closed the joint capsule; D: Finally we tied the patella with a circular suture of titanium cable, then tightened the titanium cable to form the tension band, fixed the titanium cable with cable clamps, and cut off the excessive titanium cable.
