Complete disruption of vastus intermedius tendon and partial rupture of vastus medialis tendon

Quadriceps tendon ruptures are common injuries, however isolated ruptures are rare. Particularly, reports for isolated vastus intermedius ruptures are very scarce. We present a case of a 62-years-old male patient who sustained a complete rupture of vastus intermedius tendon with a partial rupture of vastus medialis while rectus femoris tendon was intact, after a fall from standing height. Due to lag in extension, surgical treatment was performed, consisted of an end-to-end Krakow suture technique accompanied with two anchors placed on osseous attachment to the superior pole of the patella. A hinged knee brace locked in full extension was applied for 4 weeks. Gradual range of flexion was suggested after the 3rd postoperative week. Full range of motion was achieved in the 7th postoperative week.
