Description
Kaiyuan Zheng and co-authors compare two ways of doing hip replacement surgery in a 2026 study drawn from two hospitals in China. Both groups used an approach from the back of the hip. In one group the surgeon preserved the piriformis, a small muscle at the back of the hip joint; in the other the muscle was handled the standard way. The study covered 420 patients treated between 2019 and 2024 for worn hip joints or death of the thigh bone head.
Patients were checked at one week, one month, three months, and twelve months after surgery. Hip function scores started alike in both groups and stayed alike at one year, with both groups scoring in the mid-nineties on the Harris Hip Score. The paper sets out whether sparing the muscle changes recovery or the risk of the new joint slipping out of place.
