Abstract A complication of total knee arthroplasty is patellar avascular necrosis. Surgical approaches for total knee arthroplasty include the medial parapatellar approach (MPa) and, less commonly, the subvastus approach (SVa). The argument that SVa retains better patellar vascularity than the MPa was investigated on 20 participants, (SVa, n = 10; MPa, n = 10) 18 months postoperatively. Outcomes were a radionuclide bone imaging technique, a new bone vascularity scale, and an anterior knee pain numerical assessment scale. Results indicated no significant difference between groups on imaging (P = .935), the components of the bone vascularity scale, or anterior knee pain (P > .999). The SVa appears to offer no benefit over the MPa in terms of patellar vascularity or anterior knee pain.
