Gross anatomy of the patella and the quadriceps: posterior views. Note the VL and VI tendons runs vertically, and the VM inserts obliquely to the patella and becomes tendinous only a few millimetres before it inserts to the patella. Note the small region of direct continuity of the VM tendon (arrow) with the patellar tendon. P, patella; VI, vastus intermedius; VL, vastus lateralis; VM, vastus medialis.
