Perioperative outcomes of the quadriceps-sparing subvastus approach versus medial parapatellar approach for primary total knee arthroplasty.

Aims & Objectives: The quadriceps-sparing subvastus (SV) approach for total knee arthroplasty (TKA) is theorized to prevent extensor mechanism injury, accelerate recovery and is often compared to the medial parapatellar (MPP) approach. We aimed to compare postoperative outcomes of SV and MPP approaches after TKA in the veteran population.

Materials & Methods: We conducted a retrospective cohort study of all unilateral primary TKAs performed at our institution with an MPP or SV approach between January 1st, 2017 and December 31st, 2020.
