- Abstract: BACKGROUND:The titanium alloy bone trabecular bone socket cup prosthesis printed by 3D technology has superior biological characteristics,which helps to promote osteogenic differentiation of stem cells.The Kidney Tonifying and Blood Activating Decoction has the functions of tonifying the kidneys,strengthening tendons,promoting blood circulation,and relieving pain.However,the application of the combination of the two in elderly hip arthroplasty is rarely reported.OBJECTIVE:To evaluate the application value and safety of 3D printed titanium alloy bone trabecular cup prosthesis combined with modified Kidney Tonifying and Blood Activating Decoction in elderly hip arthroplasty.METHODS:A total of 200 elderly patients who received hip arthroplasty in Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2022 to January 2024 were selected and randomly divided into control group(n=100)and trial group(n=100).The control group underwent Pinnaele cup prosthesis hip arthroplasty combined with modified Kidney Tonifying and Blood Activating Decoction,while the trial group underwent 3D printed titanium alloy bone trabecular cup prosthesis hip arthroplasty combined with modified Kidney Tonifying and Blood Activating Decoction.The medication was taken continuously for 1 week before hip arthroplasty and for 4 weeks after arthroplasty.The differences in pain,swelling,hemorheology,inflammatory factors,bone metabolism,intra-articular stress,and hip abduction muscle strength were compared between the two groups to evaluate the clinical efficacy and safety of the two treatment options.RESULTS AND CONCLUSION:(1)Four weeks after surgery,the pain visual analog scale score,limb swelling,whole blood viscosity,and plasma viscosity of the trial group were lower than those of the control group(P＜0.05).The interleukin-6 level of the trial group was lower than that of the control group,and the interleukin-10 level was higher than that of the control group(P＜0.05).The levels of type Ⅰ collagen carboxyl terminal peptide β specific sequence and tartrate-resistant acid phosphatase 5b in the trial group were lower than those in the control group,while the levels of osteocalcin,bone-specific phosphatase and typeⅠ procollagen amino-terminal propeptide were higher than those in the control group(P＜0.05).The intra-articular stress and hip abduction muscle strength in the trial group were higher than that of the control group(P＜0.05).(2)Three months after surgery,the excellent and good treatment rate in the trial group was higher than that in the control group,and the incidence of safety evaluation events such as postoperative incision hematoma and infection was lower than that in the control group(P＜0.05).(3)It suggests that 3D printed titanium alloy trabecular acetabular cup prosthesis combined with modified Kidney Tonifying and Blood Activating Decoction can improve the blood rheology of elderly patients with hip arthroplasty,inhibit inflammatory response,reduce postoperative pain and swelling,and enhance bone metabolism,thereby promoting postoperative hip joint function recovery,and reducing the incidence of adverse events,with high safety.
