MIS TKA with a Subvastus Approach

  • Mark W. PagnanoEmail author


Performing minimally invasive (MIS) total knee arthroplasty (TKA) through a subvastus approach makes sense on an anatomic basis, on a scientific basis, and on a practical basis. Anatomically, the subvastus approach is the only approach that saves the entire quadriceps tendon insertion on the patella1–5 (Fig. 32.1). Scientifically, the subvastus approach has been shown, in prospective randomized clinical trials, to be superior to the standard medial parapatellar arthrotomy and to the so-called quadriceps-sparing arthrotomy3,6,7 (Table 32.1). Practically, MIS TKA with a subvastus approach is reliable, reproducible, and efficient and allows the MIS technique to be applied to a broad group of patients, not just a highly selected subgroup8 (Table 32.2).
