Arthroscopic-assisted core decompression for osteonecrosis of the femoral head.

ABSTRACT: The management of pre-collapse osteonecrosis of the femoral head is controversial. Core decompression is a technique that theoretically decreases the intraosseous pressure of the femoral head, resulting in a local vascularized healing response. Its efficacy has been shown in delaying early subchondral collapse. We describe the technique of arthroscopic-assisted core decompression of the femoral head for osteonecrosis. The advantages of this technique include evaluation of the presence or absence of articular cartilage injury, subchondral collapse, and guidance during reaming and curettage. It also allows the ability to address any concomitant soft-tissue or bony pathology associated with or in addition to the osteonecrotic lesion.

Project description:BACKGROUND: To investigate the efficacy of the sole core decompression surgery for the treatment of steroid-induced femoral head osteonecrosis. METHODS: The model was established by administration of steroids in combination with horse serum. The rabbits with bilateral femoral head osteonecrosis were randomly selected to do the one side of core decompression. The other side was used as the sham. Quantitative RT-PCR and western blot techniques were used to measure the local expression of BMP-2 and PPAR-?. Bone tissues from control and operation groups were histologically analyzed by H&E staining. The comparisons of the local expression of BMP-2 and PPAR-? and the bone regeneration were further analyzed between different groups at each time point. RESULTS: The expression of BMP-2 in the osteonecrosis femoral head with or without decompression was significantly lower than that in normal animals. BMP-2 expression both showed the decreasing trend with the increased post-operation time. No significant difference of BMP-2 expression occurred between femoral head osteonecrosis with and without decompression. The PPAR-? expression in the femoral head osteonecrosis with and without core decompression both was significantly higher than that in control. Its expression pattern showed a significantly increased trend with increased the post-operation time. However, there was no significant difference of PPAR-? expression between the femoral head osteonecrosis with and without decompression at each time point. Histopathological analysis revealed that new trabecular bone and a large number of osteoblasts were observed in the steroid-induced femoral head osteonecrosis with lateral decompression at 8?weeks after surgery, but there still existed trabecular bone fractures and bone necrosis. CONCLUSIONS: Although decompression takes partial effect in promoting bone regeneration in the early treatment of femoral head osteonecrosis, such an effect does not significantly improve or reverse the pathological changes of femoral head necrosis. Thus, the long-term effect of core decompression in the treatment of steroid-induced femoral head osteonecrosis is not satisfactory.

Project description:BackgroundVarious Joint-preserving therapy (JPT) methods have been performed and tried in recent decades, but their results and efficacy were inconsistent and controversial. The purpose of this study is to evaluate its effectiveness and whether there are statistical differences in treatment between different interventions based on published RCT studies.MethodsFollowing the PRISMA-NMA checklist, Medline, EMBASE, Web of Science, and Cochrane Library databases were searched and collected related RCT studies. The sources were searched from inception up to October 30, 2020. The primary outcomes including the rate of radiographic progression and conversion to THA and the secondary outcome -Harris Hip Scores (HHS) were extracted and compared in a Network meta-analysis.ResultsSeventeen RCT studies involving 784 patients (918 hips) with seven interventions including CD (core decompression), CD + BG (bone graft), CD + TI (tantalum rod implantation), CD + CT (Cell therapy), CD + BG + CT, VBG (vascularized bone graft), and nonsurgical or conservative treatment for ONFH were evaluated. In the radiographic progression results, CD + CT showed a relatively better result than CD, CD + BG and non-surgical treatment, the surface under the cumulative ranking curve (SUCRA) plot displayed that CD + CT (96.4%) was the best, followed by CD (64.1%).In conversion to THA results, there were no significant differences between the JPT methods and non-surgical treatment. In HHS, there was also no significant difference, other than CD + BG showed a statistical difference than non-surgical treatment only in terms of Cis, but the SUCRA was highest in non-surgical treatment (80.5%) followed by CD + CT (72.8%).ConclusionsThis Net-work meta-analysis demonstrated that there was no statistical difference in the outcome of radiographic progression and conversion to THA, also in HHS, other than CD + CT showed a relatively superior result in radiographic progression than nonsurgical treatment, namely, it's maybe an effective method for delaying disease progression or reducing disease development based on current evidence.
