Knee arthritis is one of the common diseases with the highest incidence in osteoarthrosis, which seriously affects people’s health, and as the patient’s medical history prolongs, the pain degree becomes more and more serious. In recent years, with the rapid development of nanotechnology, its application scope has gradually been involved the medical field. The application of nanotube-targeted drugs to treat osteoarthritis can repair bone to a certain extent and relieve patient pain symptom. Sports rehabilitation therapy, as an important nursing method in orthopedic treatment, can improve the patient’s body recovery ability and enhance the therapeutic effect of surgery. Based on this, this article proposes the application research of a nanotube combined with exercise rehabilitation therapy in the treatment of patients with knee arthritis. The research carried out in this article is mainly divided into three parts: the first part is the research of titanium dioxide nanotubes in orthopedic treatment, studying the diameter and drug loading of nanotubes, research on how to target the damaged bone tissue and release drugs, and discussing the tissue compatibility and safety of nanotubes to the human body; the second part is the study on exercise rehabilitation therapy in orthopedic treatment and study on how to exercise properly to enhance the patient’s body recovery; the third part is clinical investigation and research, according to the observation group in contrast with the indicators of the control group to draw conclusions. The results of this experiment show that in the clinical treatment of knee arthritis surgery, in the analysis of postoperative patients, the scores of the three groups of patients before treatment were relatively low, with scores ranging from 5 to 8, but the scores of the observation group were significantly higher than those of the first and second groups. The observation group ranged from 7 to 10. The joint scores of the observation group gradually increased at 1 week and 2 weeks after treatment. The increase in functional score was more pronounced. For patients with a longer medical history, perform appropriate helping exercises. Titanium dioxide nanotubes have good antibacterial properties as an endoplant and good histocompatibility with human bones. In the observation group combined with exercise therapy, various complications such as pain, swelling, and muscle atrophy were relatively small, allowing the patient to speed up the recovery of various body functions.

Sports ligament injury refers to muscle or joint injury caused by excessive use of limbs or long-term use of wrong training methods. This is a very common sports disease, and the body’s ability to heal itself is poor. At present, the clinical methods to treat this disease mainly include autologous structure transplantation, allogeneic structure transplantation, and artificial ligament reconstruction. Nanomaterials refer to materials made of them as basic units. Transplantation of homologous and allogeneic structures may cause immune rejection in the human body. Therefore, the use of nanomaterials to reconstruct artificial ligaments is the current research hotspot of sports injury repair. This article mainly studies the repair effect of nanomaterials on basketball sports ligament injuries. In this paper, by implanting nanofiber scaffolds in sports-injured rabbits, observing and comparing the healing, growth, and proliferation of damaged cells after implantation, and the compatibility of nanofibers with cell tissues, so as to determine that nanomaterials have an impact of lion sports injury repair and the interaction between nanomaterials and cells. According to the experimental results, the implantation of nanofiber scaffolds can greatly accelerate cell proliferation and differentiation and promote the healing of sports-damaged tissues; nanofiber scaffolds have good histocompatibility, so the use of nanomaterials can promote the repair of sports ligament injury in basketball sports.
