With the rapid development of outdoor sports in our country, the condition of hip joint injury of athletes appears constantly. With the continuous progress of modern biotechnology and iatrotechnique, nanomaterials are also gradually used in the treatment of biological medicine. The purpose of this study is to use nanoscaffold materials in combination with athletics rehabilitation therapy to treat and analyze hip injuries in athletes. In this study, 290 patients with hip injuries in our hospital from June to October 2019 were studied. The hip joint injury patients were divided into the control group and the experimental group according to sex and age. The recovery of the hip joint injury in normal condition, the recovery in the pharmacotherapy, and the recovery in the combined therapy with the nanoscaffold material were compared. The function of nanoscaffold materials in experiments can be determined by detecting changes in related indicators in vivo. The results showed that there were 48 cases of ligament injury, accounting for 67.7% of hip joint injury. 22 cases had muscle and tendon injury, and 12 cases had articular cartilage injury and bursa injury. There was no significant difference in red blood cells, lymphocytes, and white blood cells after nanoscaffold material drug delivery therapy, while parathyroid hormone and osteocalcin changed greatly, which indicated that nanoscaffold material carrier therapy could promote the absorption and treatment of drugs in hip joint. Therefore, the research conclusions of this paper is that nanoscaffold material combined with rehabilitation therapy can effectively treat athletes with hip joint injury. It will contribute to the research and practical application of nanomaterials in modern medicine.
