Abstract
Objective To investigate the clinical effect of precise platelet-rich plasma(PRP)injection combined with tanta-lum rod implantation under arthroscopy in the treatment of early osteonecrosis of femoral head(ONFH).Methods From October 2020 to October 2022,50 patients with early femoral head necrosis(62 hip joints)were divided into two groups,of which 25 ca-ses(32 hips)in the observation group were treated with arthroscopy assisted PRP injection combined with tantalum rod implanta-tion,and 25 cases in the control group(30 hip joints)were treated with simple core decompression and tantalum implantation.The X-ray films of the hip joints were reviewed at 1,2,3,6 and 12 months after the operation,and the changes of the femoral head density were observed.The Harris score of the hip joints and the VAS score of the pain were evaluated.Results The X-ray films of the hip joints 12 months after the operation showed that the femoral head in the observation group had good shape without cystic enlargement or the collapse of the femoral head,the integration of the internal plants and bone was good,and no loosening of the displacement occurred.In the control group,there were 6 cases of collapse of the femoral head,and the difference between the plant and bone integration was obvious.In the last follow-up,the effect of the observation group was significantly better than that of the control group.The Harris scores of the hip joints in the observation group were increased from(68.13±6.45)points before surgery to(89.64±7.14)points at the last follow-up.The Harris scores of the hip joints in the control group were in-creased from(68.73±7.15)points before surgery to(78.64±7.14)points at the last follow-up.The pain scores of VAS in the observation group decreased from(4.5±1.3)points to(1.8±1.1)points at the last follow-up.The VAS pain scores in the control group decreased from(4.3±1.2)points before surgery to(2.3±1.3)points at the last follow-up.The difference be-tween the two groups before and after the treatment was statistically significant(P＜0.05),and the difference between the two groups after the treatment was statistically significant(P＜0.05).Conclusion Arthroscopy assisted PRP injection combined with tantalum rod implantation and pure core decompression for early femoral head necrosis can significantly reduce the pain symptoms of the hips,improve the activity of the hips,and promote the growth of the new bones,with the short-term effects sig-nificant.It provides a new method for the clinical treatment of osteonecrosis of the femoral head.关键词
