Magnitude of Deformity Correction May Influence Recovery of Quadriceps Strength After Total Knee Arthroplasty.

ABSTRACT:

Background

Malalignment of the lower extremity is commonly seen in patients with severe osteoarthritis undergoing total knee arthroplasty (TKA) and is believed to play a role in quadriceps strength loss. Deformity correction is typically achieved through surgical techniques to provide appropriate ligamentous balancing. Therefore, this study examined the influence of change in lower extremity alignment on quadriceps strength outcomes after TKA.

Methods

Seventy-three participants (36 male; mean age, 62 years; and mean body mass index, 29.7 kg/m²) undergoing primary unilateral TKA were used in this investigation. Before surgery and at 1 and 6 months after surgery, measures of isometric knee extensor strength, quadriceps activation, and long-standing plain films were
