ObjectiveTo compare the efficacy of robot-assisted versus traditional core decompression combined with human umbilical cord-derived mesenchymal stem cell transplantation for osteonecrosis of the femoral head.MethodsA total of thirty-eight patients were divided into two groups according to the surgical technique. The observation group (20 patients, 28 hips) underwent robot-assisted core decompression, while the control group (18 patients, 22 hips) underwent traditional decompression. Both groups underwent human umbilical cord-derived mesenchymal stem cell implantation. Relevant parameters were compared between the groups.ResultsAt the final follow-up, the observation group showed lower visual analog scale scores and necrotic volume as well as higher Harris hip scores and femoral head survival rates than the control group; however, these differences were not statistically significant. The observation group required significantly fewer intraoperative fluoroscopies, experienced less intraoperative blood loss, and had a shorter operation time than the control group (all p < 0.01).ConclusionOur findings suggests that the robotic-assisted technique demonstrates comparable clinical and radiological outcomes as the traditional technique in the treatment of osteonecrosis of the femoral head. However, it may offer significant advantages in terms of surgical precision.
