Icariin (Ica), the main active component of Herba Epimedii, has been identified as an osteogenic and angiogenic phytomolecule. To develop a bioactive scaffold for enhancing bone repair, Ica was loaded into porous tricalcium phosphate (TCP) scaffolds, and the obtained porous Ica/TCP composites were investigated for treating osteonecrosis of the femoral head (ONFH) in a rabbit model. ONFH was histopathologically confirmed at two weeks after methylprednisolone acetate injection, and the rabbits were treated with porous Ica/TCP scaffolds (group A), porous TCP scaffolds (group B), and autogenous cancellous bone graft (group C). At 12 weeks, the amount of newly formed bone in group A increased significantly compared with that in group B (P = 0.003). The mean histological and radiological scores for repaired defects in group A were significantly higher than those in group B (P = 0.007, P = 0.029, respectively), but were lower than those in group C (P = 0.032, P = 0.046, respectively). In addition, the expression of vascular endothelial growth factor by immunohistochemical testing and real-time polymerase chain reaction in group A was significantly higher than that in group B (P = 0.002, P = 0.001, respectively), but was lower than that in group C (P = 0.034, P = 0.005, respectively). Therefore, Ica can be a promising osteogenic and angiogenic compound for repairing bone defects and preventing the collapse of the femoral head in ONFH.

It is still unknown whether drainage is necessary and non‐drainage is safe and acceptable after tourniquet‐free total knee arthroplasty (TKA). We aim to investigate whether non‐drainage use is accepted in TKA that is performed without a tourniquet.

PURPOSE To compare the efficacy of multiple doses of oral tranexamic acid (TXA) with topical TXA administration in reducing blood loss following total hip arthroplasty (THA). PATIENTS AND METHODS In this double-blinded trial, 117 patients undergoing primary THA were randomized to receive 2 g TXA orally 2 h preoperatively, and two doses of 1 g TXA postoperatively (oral group) or 3 g of TXA topical administration in the operating room (topical group). The primary outcome was a reduction in hemoglobin concentration. Other outcomes-such as blood loss, TXA-related cost (¥), length of hospital stay (days), complications such as pulmonary thromboembolism (PE), deep vein thrombosis (DVT), and infection, blood coagulation and fibrinolysis, and hip function-were recorded. RESULTS The mean reduction in hemoglobin level was similar between the oral and topical groups (3.07 g/dL compared with 3.12 g/dL; p = 0.85). Similarly, there was no significant difference in the mean total blood loss between oral and topical administration (863 mL compared with 902 mL; p = 0.62). Three patients received an allogeneic blood transfusion, including one patient in the oral group and two patients in the topical group (p = 0.55). The oral group had a significantly lower TXA-related cost than the topical group: ¥944 and ¥4359, respectively (p = 0.01). No PE, DVT, cardiac infarction or renal failure occurred during the 90-day follow-up. The coagulation and fibrinolysis parameters were similar between the two groups. CONCLUSION Oral TXA is equivalent to topical TXA administration in the reduction of blood loss in the setting of primary THA without drainage.

BACKGROUND The debate over the use of cemented or cementless fixation in total knee arthroplasty (TKA) has never stopped since cementless fixation was introduced. We undertook a systematic review and meta-analysis to evaluate the optimal mode of fixation (full-cementless vs. full-cemented) in TKA. METHODS PubMed, Embase, and the Cochrane Library databases up to July 2017 were searched to identify randomised controlled trials (RCTs) and quasi-RCTs comparing full-cementless TKA and full-cemented TKA. The primary outcome was implant survivorship. Secondary outcomes included radiological outcomes (maximum total point-motion [MTPM], radiolucent line, rotation degree) and clinical outcomes (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] score, Knee Society Score [KSS] score, postoperative range of movement, blood loss and complications). RESULTS Seven studies were included in the systematic review and meta-analysis. The mean follow-up was 7.1 years (range from 2 to 16.6 years). There was no difference in implant survivorship (RR, 0.98; 95% CI, 0.95-1.01; p = 0.25; I2 = 0%), MTPM (weighted mean difference [WMD], 0.13 mm; 95% CI, -0.69-0.95; p = 0.75; I2 = 89.3%) and radiolucent line (RR, 1.36; 95% CI, 0.57-3.23; p = 0.48; I2 = 54%) between the cementless and cemented methods. There was a mean 0.22° more rotation in the full-cementless fixation group (95% CI, 0.13-0.32; p < 0.01; I2 = 28.5%). There were no significant differences relating to clinical outcomes (WOMAC score, KSS score, postoperative range of movement, blood loss and complications) between the two fixation groups. CONCLUSIONS Although more overall component rotation is found in full-cementless fixation, the implant survivorship and clinical efficacy are likely similar between full-cementless and full-cemented fixation. However, future RCTs with similar cementless prosthetic coating and longer-term follow-up are still needed to confirm our findings.

Accumulating evidences have indicated that the functional -94 ins/del ATTG polymorphism in the promoter region of human nuclear factor-kappa B1 (NFKB1) gene may be associated with cancer risk. However, some studies yielded conflicting results. To clarify precise association, we performed a comprehensive meta-analysis of 42 case-control studies involving 43,000 subjects (18,222 cases and 24,778 controls). The overall results suggested that the -94 ins/del ATTG polymorphism had a decreased risk for cancer, reaching significant levels in five genetic models (dominant model: OR = 0.86, 95% CI = 0.79–0.95, P = 0.002; recessive model: OR = 0.84, 95% CI = 0.74–0.94, P = 0.003; homozygous model: OR = 0.77, 95% CI = 0.66–0.90, P = 0.001; heterozygous model: OR = 0.90, 95% CI = 0.83–0.98, P = 0.011; allelic model: OR = 0.89, 95% CI = 0.83–0.96, P = 0.002). Furthermore, the -94 ins/del ATTG polymorphism could confer a decreased or increased risk for cancer development among Asians and Caucasians, respectively. Additionally, the stratification analysis revealed a significant association between the variant and decreased risk of oral, ovarian, and nasopharyngeal cancer in Asians. After we adjusted p values using the Benjamini-Hochberg false discovery rate method to account for multiple comparisons, these associations remained.

Abundant literature confirms that intravenous (IV) and intra-articular (IA) administration of tranexamic acid (TXA) reduces blood loss in total knee arthroplasty (TKA). Oral formulations of TXA exhibit profound cost-saving benefits. However, comparisons of the clinical efficacy among three different modalities of TXA administration have not been previously investigated in the setting of TKA with no closed suction drain and tourniquet. A total of 180 patients undergoing TKA were randomized to receive 2-g oral TXA 2 hours preoperatively, 20-mg/kg IV TXA 5 minutes prior to incision, or 2-g IA TXA. The primary outcome was 72-hour blood loss. Secondary outcomes were reductions in hemoglobin, the rate of transfusions, and adverse events. No significant differences were identified with regard to the mean 72-hour blood loss among the three groups (1003 mL in oral group, 1108 mL in IV group, and 1059 mL in IA group, respectively). Similarly, hemoglobin reduction was equivalent among the groups. Only one patient in IV group exhibited deep venous thrombosis. No difference was identified regarding transfusion rates. Oral TXA results in similar blood loss in TKA, with a profound cost-saving benefit, compared with the IA and IV formulations.

The accuracy of using 2-dimensional anteroposterior pelvic radiography to assess acetabular cup coverage among patients with developmental dysplasia of the hip after total hip arthroplasty (THA) remains unclear in retrospective clinical studies. A group of 20 patients with developmental dysplasia of the hip (20 hips) underwent cementless THA. During surgery but after acetabular reconstruction, bone wax was pressed onto the uncovered surface of the acetabular cup. A surface model of the bone wax was generated with 3-dimensional scanning. The percentage of the acetabular cup that was covered by intact host acetabular bone in vivo was calculated with modeling software. Acetabular cup coverage also was determined from a postoperative supine anteroposterior pelvic radiograph. The height of the hip center (distance from the center of the femoral head perpendicular to the inter-teardrop line) also was determined from radiographs. Radiographic cup coverage was a mean of 6.93% (SD, 2.47%) lower than in vivo cup coverage for these 20 patients with developmental dysplasia of the hip (P<.001). However, both methods yielded highly correlated measurements for cup coverage (Pearson r=0.761, P<.001). The size of the acetabular cup (P=.001) but not the position of the hip center (high vs normal) was significantly associated with the difference between radiographic and in vivo cup coverage. Two-dimensional radiographically determined cup coverage conservatively reflects in vivo cup coverage and remains an important index (taking 7% underestimation errors and the effect of greater underestimation of larger cup size into account) for assessing the stability of the cup and monitoring for adequate ingrowth of bone.
