Reconstructed hip joint position and abductor muscle strength after total hip arthroplasty

Reconstructed hip joint position and abductor muscle strength after total hip arthroplasty

We evaluated 60 limbs in 30 patients with unilateral primary total hip arthroplasty and nondiseased contralateral hip. The ratio of femoral offset (FO) to the body weight lever arm (FO ratio) and the ratio of the height of hip center (HC) to pelvic height (HC ratio) were calculated on radiographs. I...
